CUBRID - Open Source Database Management System Optimized for Web

Java Stored Procedure: Invalid call: it can not return ResultSet

2012-05-11T04:59:17-07:00

I am running the following example in my cubrid database.

function:

create function rset() return cursor
as language java
name 'JavaSP2.TResultSet() return java.sql.ResultSet'

Stored procedure:

public static class JavaSP2 {
public static ResultSet TResultSet(){

try{
Class.forName("cubrid.jdbc.driver.CUBRIDDriver");
Connection conn = DriverManager.getConnection("jdbc:default:connection:");
((CUBRIDConnection)con).setCharset("euc_kr");

String sql = "select * from station";
Statement stmt=con.createStatement();
ResultSet rs = stmt.executeQuery(sql);
((CUBRIDResultSet)rs).setReturnable();

return rs;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}

CUBRID says:

execute error:-911
line 1 is not executed (error)Error description:
Invalid call: it can not return ResultSet.

I try to solve it doing casting but dont work. When I registering the function cubrid dont allow set java.sql.ResultSet as return value instead use

CREATE FUNCTION "rset"() RETURN CURSOR
AS LANGUAGE JAVA 
NAME 'JavaSP2.TResultSet() return cubrid.jdbc.driver.CUBRIDResultSet'

How do I escape strings in PHP to pass binary data to a table via an insert or update statement ?

2012-05-16T01:18:46-07:00

This is on the back of my previous question, it would be important for Cubrid to have a similar function to mysql_escape_string for passing of binary information to an SQL statement.

How should I do this in the interim, I have already done the normal replace single quotes with double single quotes.

How do I silent install CUBRID Server?

2012-05-11T08:24:45-07:00

Hi, I want to install CUBRID Server using .ini file with all the parameters, dba password, java_stored_procedure=yes, etc. How can I do it?

I wrote a RedBeanPHP driver for CUBRID

2012-03-18T06:23:52-07:00

Hi there,

Just for your information I wrote a RedBeanPHP driver for CUBRID, so this ORM is now compatible with CUBRID. While the installation was a bit challenging (fedora) I find the CUBRID database quite easy to use. The CUBRID Manager is also very nice. Great work. Here is the announcement of the CUBRID Driver:

http://www.redbeanphp.com/extra/roadmap

The driver works with PDO.

Yet another product that supports your database. If you like you may use this fact to promote the CUBRID database even more.

Cheers,

Gabor.

Please provide an example of using blob_from_file in an update or insert statement reading a file from /tmp/

2012-05-15T06:38:21-07:00

For Example

UPDATE tblfile SET fileimage = BLOB_FROM_FILE ('/tmp/image.png') WHERE fileid = '2b93d4629241d287915a422f6d1a90374de95ef0'

BUT

This is giving me a Cannot coerce blob to type unknown data type error.

fileimage is a blob

Scalability and Sharding in CUBRID

2012-05-13T20:56:07-07:00

I think that cubrid might give an answer to all of my scalability needs. I wanted to know more about it.

1) How can I deploy cubrid on amazon aws?
2) How many servers I need to start with

3) How Cubrid knows which keys to shard against?
4) Does cubrid can automatically add Amazon EC2 servers or i need to add them and tell about it?
5) How can I backup/restore DB, is it easy? and how much time it takes to restore 1TB of data
6) What is the optimal size of each shard? (in GB)
7) recommended environment to run crubid (Windows or Linux), differences if there are any
8) Why I haven't heard about crubid after two weeks of intensive searching? from what I can tell, it should be super popular?

9) Does Curbid support clustering?

10) why should I use curbid over Amazon RDS, both features and price wise?

Please help me out, just starting with Cubrid

I've spent two weeks going over all the possible options, including all the available NoSQL, NewSQL options. All middleware options, building my sharding enviroment myslef, etc, etc. There are solutions out there, but they are so expensive it hurts. I just can't believe I found you guys. Hope that I can develop my new app using Curbid. Really want to find a solution already, a DB that can easily scale with all the features I need.

Best PHP IDE to work with CUBRID Database

2012-05-14T22:34:30-07:00

When developers review various IDE for PHP, it is not accident that PHPStorm is among the top ranked. Because it is one of the best feature-rich PHP Development Tools out there. The good news is JetBrains, the company behind this project, has just released a new version of PHPStorm 4.0. If you try PHPStorm 4.0, I bet you won't wish to come back to your current IDE. It's really the smartest PHP IDE I have ever used!

I am sure there are still many geeks who use Notepad++ or TextMate to write their code. I had personally used Notepad++ for over 6 years. It is great for source code editing. It is small and fast. But when it comes to working in a team on a large project, control the version of the code, commit, push to, or auto sync with the remote stage server which is accessible only through SSH, merge the remote changes, and all this with a press of a keyboard shortcut, you need a fully fledged IDE which will help you accomplish all these effortlessly. And PHPStorm is that IDE which lets you focus on creating the beautiful code and leave the rest to the IDE.

I won't enumerate all the features available in PHPStorm in this blog, but I want to tell you only about my favorite ones.

Intelligent PHP Editor

Auto completion

It is not just the usual code completion or syntax highlighting features which are available in almost all source code editors and IDEs. In addition to that PHPStorm shows auto complete suggestions for array indexes within your PHP code. This is very convenient!

What I like even more is how easy it is to replace the code by another code suggested by PHPStorm. Assume you have accidentally typed cubrid_close() instead of cubrid_connect().

Instead of manually pressing several times on Backspace/Delete key on your keyboard to delete the "close()" part of the function, all you have to do is to place the cursor after the underscore, start typing your desired function, then press Tab key on your keyboard. This will automatically replace the rest of the word with the one selected in the auto complete list. I like this feature very much! It saves so much time!

Support for CUBRID PHP API syntax

PHPStorm is the first IDE to provide code completion for CUBRID PHP API. I would give the credit to them just for this feature!

It is not just the code completion, but also the entire documentation of the selected API is available on keyboard shortcut (Ctrl+J).

Code quality analysis

Support for PHP Code Sniffer

PHPStorm has really valuable features to improve the quality of your PHP code. Its on-the-fly error checking allows you to detect coding standard violations using popular PHP Code Sniffer. Also, it provides PEAR, Zend as well as Drupal coding style support as well as various techniques for code refactoring. It is just perfect for PHP coding.

Integrated PHPUnit

It is so easy in PHPStorm to write test cases and run them with PHPUnit. It is even more pleasant to instantly see how much of your code is covered by the tests. It helps you immediately spot where you have to fill the gaps.

Visual PHP debugger

PHP debugging in PHPStorm is very easy. In fact you need zero configuration to have it working. Once you install your favorite debugger (I personally use Xdebug; Zend Debugger is also supported), it is ready to go. You can debug both local and remote servers. The debugging session is kept alive while you move between web pages. If you have difficulties configuring the debugger, there is a step by step tutorial and even a video tutorial.

Powerful set of keyboard bindings

This is perhaps the best thing in PHPStorm. There are so many predefined keyboard shortcuts in PHPStorm that you can accomplish almost anything instantly with just your keyboard be it code committing or pushing, adding or deleting a file from your local repository, uploading a file to the remote server via SFTP or FTP, syncing with the remote VCS repository (I personally use Git, but it also supports SVN, Mercury, CVS, TFS, and Perforce). Various server side operations can be triggered by a mere shortcut.

My most favorite shortcut is Ctrl+Cmd+↑ to upload the currently active file to the remote stage server via SFTP so that I can see the changes live on the development server. It is especially convenient when you do not have the full test server on your local machine. By the way, you will not find this shortcut in PHPStorm because I have set it for myself. In PHPStorm you can assign your own shortcut to any available action. For this go to Settings > Keymap. In my case I have assigned the above shortcut for Settings > Keymap > Plugins > Remote Hosts Access > Upload to Default server. Super convenient!

Full support for PHP 5.4

The latest version of PHPStorm has full support for PHP 5.4 including traits, class member access on instantiation, short array syntax, array dereferencing on function call, binary literals, expressions in static calls, etc. If you want to develop for PHP 5.4, PHPStorm will make it very easy! It is just perfect for PHP reliant Web applications development.

Frequent updates

Last but not least, I like how frequently PHPStorm gets patches. Once in a while it pops up a message window asking you to update the IDE. The updates are available immediately on all supported operating systems (Windows, Mac OS X, Linux). You сan feel how the developers are trying to make their product better.

But...

I should say that there is one BUT, maybe the BIG one. PHPStorm is a commercial IDE (99 USD). For some this may be the important criteria when choosing the code editor. But I will tell you what! Try it (free trial for 30 days)! You will really love it! They also provide free licenses to open source projects (our team is using PHPStorm under the open source license) as well as to educational institutions. So if you are an official member of an open source project, requests your free license and enjoy coding!

Error 1023

2012-05-11T13:52:31-07:00

I am TRYING to use the Ado.net connector to get data from a resultset and is very frustrating!

Inside the source code this received from server the error 1023. I cant see it in the manual.

I am very tired to try it, and this forum and Q&A are really death, no users here.

my code:

          string ConnectionString = "server=localhost;database=demodb;port=30000;user=dba;password=123456";
            DataTable dt = new DataTable();
            DataSet ds = new DataSet();
            CUBRIDConnection con = new CUBRIDConnection(ConnectionString);

            CUBRIDCommand com = new CUBRIDCommand();
            com.CommandType = CommandType.StoredProcedure;
            com.Connection = con;
            com.CommandText = "select rset()";
            CUBRIDParameter pan = new CUBRIDParameter();
            pan.Direction = ParameterDirection.Output;
            pan.CUBRIDDataType = CUBRIDDataType.CCI_U_TYPE_RESULTSET;
            pan.ParameterName = "?p1";

　
            CUBRIDDataAdapter dap = new CUBRIDDataAdapter(com);
            con.Open();
            int val =  dap.Fill(ds);

            con.Close();

hi, as feature can be create java stored procedures directly in CUBRID Manager.

Tutorial How to Use Java Stored Procedures In .NET (code C#)

2012-05-14T09:06:35-07:00

ADO.NET doesn't provide the same data types as JDBC particularly ResultSet.

Well, my english is not good, so I need much time to write some words. Therefore, I will write all the code and exact steps, so you only need to copy and paste.

Requirements

C# compiler, editor, Visual studio any version, express, etc.
Eclipse or any java compiler.
CUBRID 8.4.1
Understanding of C# development.

Little explanation

When you run the Java stored procedure in CUBRID Manager, you can use SELECT or CALL methods. For example, if you need to call rset() stored procedure which returns STRING, then you can use CALL rset() or SELECT rset().

If you read this manual, you can find examples of Java stored procedures where you can see one with ResultSet return value. Here is the problem: ADO.NET provider cannot handle it because the ResultSet is a Java type.

But if the Stored procedure returns STRING or other native type like INTEGER you can use SELECT rset() to get the value.

Solution

My solution is get a ResultSet value by converting it to an XML file.

Example in Java:

import java.sql.*;

import cubrid.jdbc.driver.*;

import java.sql.Connection;

import java.sql.Statement;

import java.sql.Driver;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.ResultSetMetaData;


import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.DocumentBuilderFactory;

import javax.xml.transform.*;

import javax.xml.transform.stream.*;

import javax.xml.transform.dom.*;

import org.w3c.dom.Document;

import org.w3c.dom.Element;


public class JavaSP3 {

    public static String TResultSet(){

        ResultSet rs = null;

        Statement stmt = null;

        String sql;


        try {

            Class.forName("cubrid.jdbc.driver.CUBRIDDriver");

            Connection con = DriverManager.getConnection("jdbc:default:connection:");

            ((CUBRIDConnection)con).setCharset("euc_kr");


            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

            DocumentBuilder builder =factory.newDocumentBuilder();

            Document doc = builder.newDocument();

            Element results = doc.createElement("Results");

            doc.appendChild(results);

                    

            sql = "select * from athlete";

            stmt=con.createStatement();

            rs = stmt.executeQuery(sql);

            ResultSetMetaData rsmd = rs.getMetaData();

            int colCount = rsmd.getColumnCount();

                      

            while (rs.next()) {

                Element row = doc.createElement("Row");

                results.appendChild(row);

                for (int ii = 1; ii <= colCount; ii++) {

                    String columnName = rsmd.getColumnName(ii);

                    Object value = rs.getObject(ii);

                    Element node = doc.createElement(columnName);

                    node.appendChild(doc.createTextNode(value.toString()));

                    row.appendChild(node);

                }

            }


                      

            String valor = getDocumentAsXml(doc);

            return valor;

                     

        }

        catch (Exception e)

        {

            e.printStackTrace();

        }

        

        return null;


    }


    public static String getDocumentAsXml(Document doc)

          throws TransformerConfigurationException, TransformerException {

        DOMSource domSource = new DOMSource(doc);

        TransformerFactory tf = TransformerFactory.newInstance();

        Transformer transformer = tf.newTransformer();

        //transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION,"yes");

        transformer.setOutputProperty(OutputKeys.METHOD, "xml");

        transformer.setOutputProperty(OutputKeys.ENCODING,"ISO-8859-1");

        transformer.setOutputProperty

           ("{http://xml.apache.org/xslt}indent-amount", "4");

        transformer.setOutputProperty(OutputKeys.INDENT, "yes");

     

        java.io.StringWriter sw = new java.io.StringWriter();

        StreamResult sr = new StreamResult(sw);

        transformer.transform(domSource, sr);

        return sw.toString();

     }


}

C# code:

using System.Data;

using CUBRID.Data.CUBRIDClient;

using System.Data.Common;

using System;


namespace ConsoleApplication1

{

    class Program

    {

        static void Main(string[] args)

        {


            string ConnectionString = "server=localhost;database=demodb;port=30000;user=dba;password=123456";

            DataTable dt = new DataTable();

            DataSet ds = new DataSet();

            CUBRIDConnection con = new CUBRIDConnection(ConnectionString);


            CUBRIDCommand com = new CUBRIDCommand();

            com.CommandType = CommandType.Text; //Important ADO.NET driver crash using call convention

            com.Connection = con;

            com.CommandText = "select rset();";

            CUBRIDParameter pan = new CUBRIDParameter();

            con.Open();

            DbDataReader reader = com.ExecuteReader();

            CustomAdapter da = new CustomAdapter();

            da.FillFromReader(dt, reader);

            con.Close();


            DataRow fila = dt.Rows[0];

            Console.WriteLine(fila[0].ToString());

            Console.ReadKey();           


        }

    }


   

    public class CustomAdapter : System.Data.Common.DbDataAdapter

    {

        public int FillFromReader(DataTable dataTable, IDataReader dataReader)

        {

            return this.Fill(dataTable, dataReader);

        }

        protected override System.Data.Common.RowUpdatedEventArgs CreateRowUpdatedEvent(DataRow a, IDbCommand b, StatementType c, System.Data.Common.DataTableMapping d)

        {

            return (System.Data.Common.RowUpdatedEventArgs)new EventArgs();

        }


        protected override System.Data.Common.RowUpdatingEventArgs CreateRowUpdatingEvent(DataRow a, IDbCommand b, StatementType c, System.Data.Common.DataTableMapping d)

        {

            return (System.Data.Common.RowUpdatingEventArgs)new EventArgs();

        }


        protected override void OnRowUpdated(System.Data.Common.RowUpdatedEventArgs value)

        {


　

        }

        protected override void OnRowUpdating(System.Data.Common.RowUpdatingEventArgs value)

        {


　

        }

    }


}

See these lines:

CUBRIDCommand
com = new CUBRIDCommand();
com.CommandType = CommandType.Text; //Important ADO.NET driver crash using call convention
com.Connection = con;
com.CommandText = "select rset();";

CommandType need be Text, the CUBRID engine will return you the result as STRING.

This will get you aN XML document with all the resultSet value. Of course the XML file will be very big, so you will need some compression.

You should also create this function in CUBRID:

CREATE FUNCTION "rset"() RETURN STRING

AS LANGUAGE JAVA

NAME 'JavaSP3.TResultSet() return java.lang.String'

And load the .class file generated in Eclipse using:

C:\CUBRID\bin\loadjava -y demodb JavaSP3.class

JavaSP3.class is the class generated for Eclipse, you can find it the bin directory after you compile the .java file.

JWhoisServer CUBRID Tutorial

2012-05-12T00:58:17-07:00

This tutorial will cover how to use JWhoisServer with CUBRID. The first step is of course to download and install the JWhoisServer application according to your specific environment. If you require any help regarding the installation of JWhoisServer, check out the detailed documentation available here:http://jwhoisserver.sourceforge.net/

After installing JWhoisServer, you must configure the Database. In order to use CUBRID as the database, you must follow these easy steps:

Create a database to use (for example let's name the database: "jwhoisserver") using either CUBRID Manager or "cubrid createdb jwhoisserver".
Start the database either from CUBRID Manager or by using "cubrid server start jwhoisserver".
Run the following SQL scripts found in the sql/cubrid folder:
- struct.sql
- data.sql
- test.sql (optional)
The scripts can be ran using csql or CUBRID Manager (right click on the database and choose "Run SQL Script").
Copy cubrid_jdbc.jar file to the jdbcdrivers folder within the installation folder of JWhoisServer

Configure server.cfg file to use the CUBRID connection parameters (the db section should like the code below):

###### db #####################################################

db.type=cubrid

# connections settings
# see: /etc/jwhoisserver/dbconfig.cfg
db.host=localhost
db.port=30000
db.name=jwhoisserver
db.user=public
db.pass=

###### END db #################################################

Depending on your setup, you will have to quote special field names.
For the sample database this has to look like:

# cubrid requires to escape special names
db.person.tablejoin=LEFT JOIN country ON country_key\=country_fkey LEFT JOIN "type" on type_key\=type_fkey
db.person.display=mntnr_fkey;"type";name;address;pcode;country."short" AS country;phone;fax;email;changed

db.domain.displayshort="domain";'active' AS status
db.domain.display="domain";mntnr_fkey;changed
db.domain.table="domain"
db.domain.qfield="domain"

Java Whois Server

2012-05-12T00:27:58-07:00

JWhoisServer is a small, fast and highly configurable RFC 3912 compliant whois server written in java and using a Relational Database Management System (RDBMS) as a storage engine.

JWhoisServer has support for IPv6 and IDN and is ready for ICANNs "new gTLDs Program".

ART CUBRID Tutorial

2012-05-13T19:08:13-07:00

This tutorial will cover how to use ART with CUBRID. First of all, install the latest version of CUBRID. Then, install ART using the tutorial presented here: http://art.sourceforge.net/InstallArt.html (pay attention to the note below).

Important! Before you define the ART properties in the installation process above, you must follow these steps:

1. Create a CUBRID database. We'll call it "artdb" in our example.

2. Connect to the database as the public user and run the SQL scripts (right click on database name and select "Run SQL Script") located within the ART archive you have downloaded: database\art_tables.sql and database\quartz\tables_cubrid.sql

3. The properties for the CUBRID database are: cubrid.jdbc.driver.CUBRIDDriver (JDBC Driver) and jdbc:cubrid:localhost:30000:artdb:public:: (JDBC URL). We use "localhost" with no password. Change the values to your IP address and database password for public user.

Now you are ready to create your ART Queries. Just follow the simple steps below and you will set up ART with CUBRID in no time.

1. Login

The default credentials are admin/admin.

2. Define a new datasource

From the Admin Console, click on the Datasources button

and define connection parameters to your database:

JDBC Driver: cubrid.jdbc.driver.CUBRIDDriver

JDBC URL: jdbc:cubrid:<ip_address>:<port>:<database>:<user>:<password>:

Example URL: jdbc:cubrid:localhost:30000:demodb:public:: (dba with no password)

3. Define a new query

Back to the Admin Console, click on the Objects button to reach the Object Management Console

4. Click on Create New Object and define a new query

This sample query shows how to define parameters: just surround the parameter label with #.

5. Click on Save Changes to reach the Object Editor page

6. Click on the Parameters button, then New to create the new parameter

If the query doesn't use parameters, this step can be skipped.

That's all.

From the Admin Console, click on Users to create a new user and then on User Privileges to grant the user permission to run the query.

Have the user to set the View Mode to Schedule to get the result in his mailbox at a given time (if the user has the required admin level to schedule jobs).

SIDU CUBRID Tutorial

2012-05-06T23:32:00-07:00

Using SIDU to connect and run SQL in CUBRID is very easy and straightforward. No need to install or configure SIDU.

Download and extract

Just download the zip archive and extract into a directory accessible by your Web browser. In this tutorial we will extract it to http://localhost/sidu35/.

Connect to a database

When you navigate to your http://localhost/sidu35/. Choose "CUBRID" as your database engine and fill out the necessary database connection fields.

Notice that you can connect to more than one database simultaneously by separating them with semicolon. This assumes that the database user is the same, i.e. username and password are the same for both databases.
Also you can easily to any remote database considering that ports are open on the remote server.

Before you actually connect to a database, you may want to test the connection by clicking on the Test button. If the connection can be established using the provided credentials, you will see the "Connection OK" message in green as shown below. Now you can press the "Connect" button.

Databases and tables

Once you are connected, you can see a list of databases and tables on the left panel.

If you click on any table, SIDU will display first 15 records of this table by running "SELECT * FROM tbl ORDER BY 1 DESC LIMIT 15".

Editing in Query Results

You can edit records/column directly from the query results. Each field in the query result is an editable input field. Place the cursor and start typing and changing values. You can change multiple rows at once. When done editing, press the "Save" icon (7th in the results panel toolbar above the results). This will save all the changes automatically. Isn't it super convenient!?

Filter in Query Results

Another great feature in SIDU is the filtering the results. In the "where" field right below the results toolbar enter a valid SQL condition. Then press the green arrow button, which is to right of the "where" field, to narrow the search scope.

Remember that in CUBRID strings are wrapped in single quotes.

Execute Multiple Queries

In SIDU you can also execute multiple SQL. There are two different ways to do this:

Run All will execute all SQL statements one by one, but display the results from only the first query.
Multi will execute all SQL statements one by one, and will displays all results obtained from each query.

Below is the output of Run All command.

And this is the output of Multi command. Notice that both queries results are displayed.

Refresh Window

When you create/drop/alter a table, the panel with a list of databases and tables is not automatically refreshed. In order to refresh the page, click on the Refresh "Window" icon on the main toolbar.

Conclusion

There are many other things that SIDU can do, but we leave the rest to you! SIDU is a really great app. It does exactly what its name says: SELECT, INSERT, DELETE, UPDATE. If you do not need any sophisticated database administration functionality, SIDU may be exactly what you need. It is ideal for Web developers!

How to call Java Stored Procedure from C#? (Solved)

Semantic: Cannot coerce host var to type date.

2012-05-13T11:56:51-07:00

I am very unhappy, this database has many bugs with ADO.NET.

I am trying to insert to datetime to database.

#region FechaNacimiento
CUBRIDParameter tblpacientesfechanacimiento = new CUBRIDParameter();
tblpacientesfechanacimiento.CUBRIDDataType = CUBRIDDataType.CCI_U_TYPE_DATE;
tblpacientesfechanacimiento.Direction = System.Data.ParameterDirection.Input;
tblpacientesfechanacimiento.ParameterName = "?p11";
tblpacientesfechanacimiento.Value = objeto.tblPacientesFechaNacimiento;
#endregion
com.Parameters.Add(tblpacientesfechanacimiento);

tblPacientesFechaNacimiento is type "DateTime"

When can give me a feedback, I have 3 days fighting with this database, is very annoying!! has many problems!!! I am thinking in rollback to postgresql.

How to return a Java Resultset on CUBRID function

2012-05-11T06:17:01-07:00

Hi,

I am trying to return a resultset from a java stored procedure, of course, I use a function to get the result but the server say error when execute the function.

Server error is:

 execute error:-911
line 1 is not executed (error)

Error description:
Invalid call: it can not return ResultSet.

my function:

 CREATE FUNCTION "rset"() RETURN CURSOR
AS LANGUAGE JAVA 
NAME 'JavaSP2.TResultSet() return cubrid.jdbc.driver.CUBRIDResultSet'

the server set automatically return cubrid.jdbc.driver.CUBRIDResultSet instead return java.sql.ResultSet as example in the link http://www.cubrid.org/manual/840/en/Note

(this editor is very disgusting has very problems to indent code nad insert images)

my Stored procedure:

code

 import  java.sql.*;

import cubrid.jdbc.driver.*;

public class JavaSP2 {
 
public static  cubrid.jdbc.driver.CUBRIDResultSet TResultSet(){
  
    	 try{
   		  
             Class.forName("cubrid.jdbc.driver.CUBRIDDriver");
             Connection con = DriverManager.getConnection("jdbc:CUBRID:localhost:33000:demodb:::","dba","123456");           
   		     String sql = "select * from athlete";		
   		     CUBRIDStatement stmt= (CUBRIDStatement) con.createStatement();		
   		     CUBRIDResultSet rs = (CUBRIDResultSet)stmt.executeQuery(sql);		
   		  return  (cubrid.jdbc.driver.CUBRIDResultSet)rs;
   		  } 
   	      catch (Exception e)
   	      {		
   		     e.printStackTrace();
 }
   	  	return null;
 
  }
 
}

Create the demodb CUBRID Demo Database

2012-04-16T19:12:47-07:00

In this tutorial you will learn how to quickly create the demodb CUBRID demo database which comes with every installation of CUBRID. This assumes that you do not have demodb database already installed, which is usually automatically installed during [CUBRID Installation Instructions|CUBRID installation]. If you have it installed, follow [Getting started with demodb (CUBRID Demo Database)|Getting started with demodb] guide.

Note: For Ubuntu demodb can be installed using sudo apt-get cubrid-demodb ([Installing CUBRID on Ubuntu])

The demodb database files are included in CUBRID binaries. Therefore when you install CUBRID, the demodb files can be found in /demo directory inside the directly where you installed CUBRID. To find where CUBRID has been installed type $CUBRID in the command line. This will give you the directory where CUBRID files reside.

In the /demo directory you will find two files:

demodb_schema
This files contains all the SQL instructions which CUBRID has to execute to create the demodb database.
demodb_objects
This file contains all the data which will be INSERTed into demodb database.

Before creating any database, you need to decide in which directory you would like to keep its files. In this tutorial let's assume we want to keep files for this database in our user's home directory in "CUBRID_databases" directory.

cd ~
mkdir CUBRID_databases
cd CUBRID_databases
mkdir demodb
cd demodb

Now run the following command when you are in /demodb directory to create the demodb database.

cubrid createdb --db-volume-size=100M --log-volume-size=100M demodb

This will create the demodb database and allocate 100 megabytes of disk space (DB Volume) for it. For this demo database 100M is enough. For other databases you create, you can adjust these values. See Creating Database manual page.

Now load both demodb_schema and demodb_objects files into the newly created demodb database.

cubrid loaddb -u dba -s $CUBRID/demo/demodb_schema -d $CUBRID/demo/demodb_objects demodb

This will load all the demodb database's data into CUBRID Server. dba will become the owner of this database with a blank password.

Congratulations! Now CUBRID demodb database has been loaded and ready to be explored!

At this moment you may want to continue to [Getting started with demodb (CUBRID Demo Database)|Getting started with demodb] tutorial.

Installing CUBRID on Ubuntu

2012-01-24T20:49:06-08:00

To install CUBRID using apt-get on Ubuntu, we need to add CUBRID's repository so that Ubuntu knows where to download the packages from, and then tell the OS to update its indexes.

sudo add-apt-repository ppa:cubrid/cubrid
sudo apt-get update

Now install the latest version of CUBRID:

 sudo apt-get install cubrid

To install earlier version, indicate the version as:

sudo apt-get install cubrid-8.3.1

To complete the installation and set the CUBRID PATH variables, reboot your OS. Until you reboot, you can also run the command ". /etc/profile.d/cubrid.sh" every time you open up a terminal if cubrid command is not found.

Optional: If you want to install the demodb sample database, run the command:

 sudo apt-get install cubrid-demodb

Important! If you encounter any permission errors, make sure all files in /opt/cubrid folder are accessible by the "cubrid" user. To ensure this, use the command:

sudo chown cubrid:cubrid -R /opt/cubrid

Sharing Connection Information in the CM and CQB_kr

2012-05-03T00:03:36-07:00

사용중인 큐브리드 매니저에 등록된 수많은 호스트 접속정보를 어떻게 다른 PC의 큐브리드 매니저로 적용할 수 있을까. 물리적으로다른PC에서의 큐브리드 매니저에 호스트 정보들을 수동으로 등록하는 것은 매우 번거로운 작업이다. 이번 글에서는 간편하게 접속정보를 이관하는 방법을 소개한다.

1. CM 기존버전의 접속 정보 파일을 백업한 후 새 버전의 설정 파일을 덮어쓰기
CUBRID Manager 8.4.0이전 버전에서는 호스트정보 이전 기능을 제공하지 않는다. 따라서, 수동으로 기존버전의 CM설정파일을 별도로 복사한 후, CUBRID Manager 새버전을 설치한 후 동일 파일을 덮어쓰기 한다.

설정파일 : cubridmanagerworkspace.metadata.pluginsorg.eclipse.core.runtime
.settingscom.cubrid.cubridmanager.ui.prefs

2. CM 기존버전이 있는 상태에서 CM새버전을 추가 설치한 후 워크스페이스전환

CM 기존 버전이 있는 시스템에서 별도디렉터리에 최신 버전의 CM클라이언트를 설치한다. 이후, 새버전의 CM에서 기존 워크스페이스로 전환하여 접속 호스트 정보를동일하게 사용할 수 있다.

그림1 - 같은 PC에 두 버전의 CM

매니저에서 <파일> -> <워크스페이스 전환> -> 워크스페이스경로에서 CM 기존 버전의 워크스페이스를 지정하여 접속 환경을 공유할 수 있다.

그림2 - 워크스페이스 전환을 위한 워크스페이스 경로 설정

그림3 - 버전이 다른 CUBRID매니저가 같은 워크스페이스를 사용하여 동일한 접속 환경을 공유한 화면

3. CM 기존버전이 있는 상태에서 CM 새 버전을 추가 설치한 후 워크스페이스가져오기
CM 8.4.0 이상 버전에서는 <파일> -> <워크스페이스 가져오기> 메뉴를 통해 기존 버전의 워크스페이스를 새 버전에 추가할 수 있다. <그림4>와 같이 가져오기할 워크스페이스 경로를 선택하면, 새 버전에 사용중이던 접속 환경이 추가된다.

그림4 - 워크스페이스가져오기

그림5 - 워크스페이스 가져오기 예시

4. 접속정보 내보내기/가져오기 기능을 추가하여 접속 정보 이관하기
CM 8.4.1 버전 이상부터는 일부/전체 호스트에 대한 접속 정보를 xml 파일로 내보내기하고, 이를 가져오기할 수 있다. 이를 사용하여 공유하고자 하는 접속 정보를 원격 운영자 환경에 쉽게 적용할 수 있다. <파일> -> <접속정보 내보내기>를 클릭하여, 접속 정보를 덤프할 호스트를 선택한다. 아래 예시에서는 a_host, b_host호스트 정보를 지정한 디렉토리에 xml파일로 내보냈다.

그림6 - 접속정보 내보내기

원격의 다른 컴퓨터에서는 ab_host.xml을 선택하여 호스트정보를 가져올 수 있다.

그림7 - 접속정보 가져오기

※주의사항: 접속정보 설정파일인com.cubrid.cubridmanager.ui.prefs 또는 접속정보 내보내기를 수행한*.xml은 호스트

이름, IP, 접속포트, JDBC 드라이버, CM 사용자 계정, 암호가 정보가 저장되어 있으므로, 파일 공유 시

유의하여야 한다.

//아래는 ab_host.xml의 내부이다.
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<hosts>
