CUBRID Q&A

Join between multiple Shard

2013-03-20T20:17:56-07:00

Hi,

I might miss this out when skimming tru the docs. How do we run query (join) accross multiple shard? if I had few tables in the join that is sharded and they are shard base on different columns, how will the performance like? any best practices or things to avoids?

I forgot my DB password. How can I reset it?

2013-03-18T19:20:04-07:00

The previoud employee used auto-saveed DB's password in the client tool. Unfortunately he didn't tell me what it is.

I cannot access a DB. On the console, is it possible to reset DB password? I know DBA is a username.

[CUBRID][ODBC CUBRID Driver][-1006]Server handle not found

2013-03-18T18:31:46-07:00

I am developing my application with CUBRID ODBC.

When querying with SELECT, fetching the result works fine. When the last data doesn't exist, it should return False so to end up While loop, however it returns the following error after reader.Read()

ERROR [HY000] [CUBRID][ODBC CUBRID Driver][-1006]Server handle not found

ERROR [01000] [CUBRID][ODBC CUBRID Driver][0]Fetch error

As I said, obtaining results is fine but that error seems a little uncomportable.

I encountered Error code= -41 and Error code= -52 Internal error: object overflow address 0|760|-1 may be corrupted

2013-02-12T17:42:22-08:00

From today, all of sudden it is unable to select data.

When tried the 1st query, the error was -493

Error messages in a SQL log file:
Syntax: Internal error: object overflow address 0|760|-1 may be corrupted. select * from scan_temp where (rownum between 1 and 5000)

I searched how to handle this, and the link http://www.cubrid.com/zbxe/346902 said I should try "cubrid checkdb" so I did.

cubrid chckdb -S -r [databasename]

then I have found different error codes(-41 and -52) the log file of [databasename]_checkdb :
Time: 02/07/13 10:36:29.408 - ERROR *** file ..\..\src\storage\file_manager.c, line 5089 ERROR CODE = -41 Tran = 1, EID = 1

Internal error: object overflow address 0|760|-1 may be corrupted.

---------------------------

I also tried to backup with cubrid backupdb utility, but failed.

How should I do?

Error: 13 An I/O error occurred while reading page 16384 of volume ..Invalid argument

2013-02-12T17:21:31-08:00

I am using CUBRID 2008 R2.2 version on Windows 2003 for years and recently the following error occurs :

02/12/13 11:44:44.965 ERROR -13 1 37 An I/O error occurred while reading page 16384 of volume "C:\CUBRID\databases\SPOMS\SPOMS_data_x001".... Invalid argument

I have seen many times these days. What happened in our CUBRID server and how can I solve the problem?

Strange behavior in HA mode

2013-01-02T00:54:07-08:00

Hi!

I setup a ha cluster with master+slave following this tutorial: http://www.cubrid.org/manual/843/en/CUBRID%20HA.

I called my nodes : cubrid and cubrid2.

All nodes have this in cubrid.conf:

[@demodb]
ha_mode=on
force_remove_log_archives=no
log_max_archives=100

cubrid_ha.conf:

[common]
ha_copy_sync_mode=sync:sync
ha_port_id=59901
ha_node_list=demodb@cubrid:cubrid2
ha_db_list=demodb
ha_apply_max_mem_size=500

cubrid@cubrid:~$ cubrid heartbeat status
@ cubrid heartbeat list
 HA-Node Info (current cubrid, state master)
   Node cubrid2 (priority 2, state slave)
   Node cubrid (priority 1, state master)
 HA-Process Info (master 882, state master)
   Applylogdb demodb@localhost:/var/opt/cubrid/databases/demodb_cubrid2 (pid 3342, state registered)
   Copylogdb demodb@cubrid2:/var/opt/cubrid/databases/demodb_cubrid2 (pid 3340, state registered)
   Server demodb (pid 3123, state registered_and_active)


cubrid@cubrid2:~$ cubrid heartbeat status
@ cubrid heartbeat list

 HA-Node Info (current cubrid2, state slave)
   Node cubrid2 (priority 2, state slave)
   Node cubrid (priority 1, state master)
 HA-Process Info (master 2478, state slave)
   Applylogdb demodb@localhost:/var/opt/cubrid/databases/demodb_cubrid (pid 2704, state registered)
   Copylogdb demodb@cubrid:/var/opt/cubrid/databases/demodb_cubrid (pid 2702, state registered)
   Server demodb (pid 2485, state registered)

When I do some benchmark on the node "cubrid2", I can see node "cubrid" sending the data to cubrid2 then cubrid2 to my client. Using "top" command I can see node "cubrid" becomes busy with many INSERT, where as node "cubrid2" idle.

When I shutdown the node "cubrid", "cubrid2" becomes the new master but I can't send any query to cubrid2, it times out (trying to fetch data from node "cubrid"). When node "cubrid" is back, cubrid2 answer (I have to reload the heartbeat).

I'm using CUBRID version 8.4.3 from Ubuntu (12.04) repository

Thanks!

비동기 질문

2013-01-03T20:25:25-08:00

node.js에서 node-cubrid를 이용 중인데요.

한번에 여러 query()를 보내니, 'Another query is already in progress! - denying current query request.' 라는 메시지가 나옵니다. 아무래도 비동기를 지원하지 않는 것 같은데요.

node.js는 근본이 비동기인데, 쿼리 실행할때마다, 커넥션 새로 맺고 쿼리 실행하고 하면, 잘 버틸 수 있을지 의문이 들구요. 한가지 불편한 것은 비동기 방식으로 작성하다가, cubrid에서만 동기 방식으로 작성해야되니, 여러가지를 고려 안할 수가 없네요. mysql 모듈은 비동기를 잘 지원하던데, cubrid는 비동기 지원이 힘든건가요?

Error: The argument is invalid

2012-11-15T19:21:04-08:00

When I execute a query "SELECT * FROM t_info" on Java application thru CUBRID JDBC,
an error "The argument is invalid" popped up. I'd like to know what happened and how I handle.

Error: Your transaction has been unilaterally aborted by the system.

2012-11-12T20:00:06-08:00

When I insert records into CUBRID DB(2008 R3.0), the following error was popped up.
"ERROR CA001CUBRIDCUBRID ODBC Driver Transaction(index1, dba@localhost|20383) has been unilaterally aborted by the system"
What does it mean and what can I do?

JDBC: Cannot coerce host var to type nchar

2012-04-18T07:01:55-07:00

I created a test table with all *char types supported by CUBRID.

When using JDBC to persist a row in which each column is set to a string value containing only uppercase latin letters (e.g. char_col=KFX, varchar_col=J, nchar_col=XZDFOY, nchar_varying_col=YYCY), I get the following exception:

Caused by: cubrid.jdbc.driver.CUBRIDException: Semantic: Cannot coerce host var to type nchar.
    at cubrid.jdbc.driver.CUBRIDConnection.createCUBRIDException(CUBRIDConnection.java:829)
    at cubrid.jdbc.driver.CUBRIDStatement.checkExecuteError(CUBRIDStatement.java:941)

    at org.databene.platform.db.DBSystem.persistOrUpdate(DBSystem.java:867)
    ... 44 more

The code that provoked the error was something like this:

            PreparedStatement statement = ...;
            statement.setObject(1, "KFX");
            statement.setObject(2, "J");
            statement.setObject(3, "XZDFOY");
            statement.setObject(4, "YYCY");
            int rowCount = statement.executeUpdate();

The table definition is

    create table chartest (
        char_col          char(4) not null,
        varchar_col       varchar(8) not null,
        nchar_col         nchar(6) not null,
        nchar_varying_col nchar varying(10) not null
    );

What's wrong?

What does "Error: CCI, -4, Cannot communicate with server" mean?

2012-02-14T20:00:49-08:00

I installed CUBRID and the PHP API yesterday. Everything was working perfect. I was quite glad. I created some code and could work with CUBRID. But today in the morning I started my Web server, navigated to my site, and I saw this error:

Error: CCI, -4, Cannot communicate with server

What does it mean, and how can I resolve it?

How do I SHOW CREATE TABLE in CUBRID?

2011-11-28T22:43:30-08:00

MySQL provides SHOW CREATE TABLE syntax which shows the CREATE TABLE statement that creates the given table including all its CONSTRAINTS and INDEXes. How do I obtain the same information in CUBRID?

Edit: I need an SQL solution so that I can execute the query in scripting language such as PHP. So, CUBRID Manager solution is not exactly what I am looking for.

Considering that $object_name = 'stadium', the following will be the output.

CREATE TABLE stadium(
    code INTEGER NOT NULL,
    nation_code CHAR NOT NULL,
    name VARCHAR(50) NOT NULL,
    area NUMERIC,
    seats INTEGER,
    address VARCHAR(100),
    CONSTRAINT pk_stadium_code PRIMARY KEY (code)
);

Does anyone know pure PHP solution?

Can I install and run two versions of CUBRID on the same machine?

2012-04-12T07:04:15-07:00

I need to test my app against both versions and I'm not sure if installing both would be a good idea.

I'm interested in knowing if this would work both on Windows and on Ubuntu.

Thanks!

How does CUBRID compare to Postgres in terms of security (brute force, sql injection, etc.)?

2012-10-11T21:25:19-07:00

How does CUBRID compare to Postgres in terms of security (brute force, sql injections, etc.)? I am currently weighing my options right now and am impressed with CUBRID's speed but an concerned about security and data protection.

Does the CUBRID db supports the Grails Hibernate function?

2012-10-08T00:44:19-07:00

I am encountering big problem with the cubrid database and grails hibernate function. I have created the domain class and the mappings as follow.

class DEvent {
    String city
    String name
    DUser organizer
    String venue
    Date startDate
    Date endDate
    String description
    
    static hasMany = [volunteers:DUser, sponsorships:SponsorShip, tasks:Task, messages:Message]
    
    String toString(){
        "$name, $city"
    }

    static constraints = {
        name()
        city()
        description(maxSize : 5000)
        organizer()
        venue()
        startDate()
        endDate()
        volunteers(nullable : true)
        sponsorships(nullable : true)
        tasks(nullable : true)
        messages(nullable : true)
    }

And my DUser domain class look like this:

class DUser {
    String fullName
    String userName
    String password
    String email
    String website
    String bio
    
    String toString(){ fullName}
    
    static constraints = {
        fullName()
        userName()
        email()
        website()
        bio(maxSize:5000)
    }
}

When i try to run the grails application it prompted to a error message l

How to connect the Grails web application with CUBRID database?

2012-10-05T00:36:13-07:00

Hi,

I am creating web application with Grails web frame work. I have created the application and modify the DataSource.groovy file like this.

dataSource {
    pooled = true
    driverClassName = "cubrid.jdbc.driver.CUBRIDDriver"
    username = "dba"
    password = "123"
}

And my environment for the connection is development coded like this which connects my application to the CUBRID database.

environments {
    development {
        dataSource {
            dbCreate = "create" // one of 'create', 'create-drop', 'update', 'validate', ''
            url = "jdbc:cubrid://localhost:30000/grailsDB"
        }
    }
}

I tried several times with CUBRID bt its not work out. It populates the following error message.

Error creating bean with name 'transactionManagerPostProcessor': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Cannot resolve reference to bean 'hibernateProperties' while setting bean property 'hibernateProperties'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateProperties': Cannot resolve reference to bean 'dialectDetector' while setting bean property 'properties' with key [hibernate.dialect]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dialectDetector': Invocation of init method failed; nested exception is org.springframework.jdbc.support.MetaDataAccess Exception: Error while extracting DatabaseMetaData; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class 'cubrid.jdbc.driver.CUBRIDDriver'.

The driver is not supported (Cannot load JDBC driver class 'cubrid.jdbc.driver.CUBRIDDriver' Error message) but the application is coded in Groovy language. Its well supported with Java language. Please give a solution it would be a great help. Thank you.

How can you catch an Exception in python using the CUBRIDdb driver?

2012-10-04T08:11:17-07:00

I want to catch the Error exception or a specific exception using the Python driver. I saw nothing related to this in the manuals.

Does CUBRID support empty list in IN operators like "WHERE id IN()"?

2011-11-07T23:53:42-08:00

I am generating in the code an SQL statement which has IN operator in the WHERE clause. IN operator should received a list of record IDs. However what will happen if that list is just empty?

MySQL correctly parses an empty IN() in which case it just says that nothing has been fond.

Does CUBRID accept empty list in IN operator?

How does CUBRID handle the case sensitivity of identifiers ?

2012-09-25T00:54:56-07:00

I've noticed that CUBRID is case insensitive in regards to identifiers, which goes against the SQL standard, which requires that quoted identifiers be handled in a case sensitive manner. Is this the way CUBRID does it by default or can it be changed using a setting ?

How do I drop a UNIQUE index ?

2012-09-25T01:45:01-07:00

I ran the following commands:

CREATE TABLE "ITEMS" ("N" integer, "A" integer);

CREATE UNIQUE INDEX "test_index" ON "ITEMS" ("N");

ALTER TABLE "ITEMS" DROP INDEX " test_index";

and I got the error:

Error description:

Index "test_index" does not exist.

How can I remove this unique index ?

Can't create composite foreign key with a different cardinality

2012-09-25T02:00:42-07:00

I can't create composite foreign key with a different cardinality than the referenced table's primary key, even if there is a unique index:

CREATE TABLE "ITEMS" (

"ID" integer AUTO_INCREMENT PRIMARY KEY,

"ITEM_ID" integer FOREIGN KEY REFERENCES "ITEMS",

UNIQUE ("ITEM_ID", "ID"),

FOREIGN KEY ("ID", "ITEM_ID") REFERENCES "ITEMS"("ITEM_ID", "ID")

);

gives error:

The number of keys of the foreign key 'fk_items_id_item_id' is different from that of the primary key 'pk_items_id'.

How can you get CUBRID system parameters using SQL ?

2012-09-20T04:01:22-07:00

In CSQL you can use the following function:

;Get system_parameter - get the value of a system parameter.

I need the same output as ";Get ansi_quotes" and ";Get no_backslash_escapes" in either SQL or using the Python Driver.

Basically, I need to know if ansi_quotes and no_backslash_escapes options are active within cubrid.conf. For other scenarios it would be good to be possible to obtain using SQL the values specified in the manual page:

http://www.cubrid.org/manual/841/en/cubrid.conf%20Configuration%20File%20and%20Default%20Parameters

How can you get Collations list from the server ?

2012-09-20T02:14:25-07:00

In MySQL this can be obtained using "SHOW COLLATION" query. Is there a CUBRID equivalent ?

How to find out if the database is case sensitive or not regarding table names ?

2012-09-19T22:41:58-07:00

In MySQL, in order to find out if the database table names are case sensitive, you can use "SHOW VARIABLES LIKE 'lower_case_table_names' ". What's the equivalent for CUBRID ?

Case-insensitive identifiers and object names

2011-11-04T01:27:11-07:00

The object names in CUBRID are case-insesitive? Is there a parameter controlling this?

Does it make any difference in SQL and drivers what letters-case is used?

How can you get the transaction isolation level in CUBRID ?

2012-09-19T22:08:04-07:00

Hello,

I tried running the command "GET TRANSACTION ISOLATION LEVEL;" in CUBRID Manager and Python Driver. I followed the example below:

http://www.cubrid.org/manual/841/en/GET%20TRANSACTION%20ISOLATION%20LEVEL

Instead of getting the result, in Python Driver I obtained a "None" object, while in CUBRID Manager, the output was simply:

1'th SQL successfully executed.[0.446 second]
GET TRANSACTION ISOLATION LEVEL;

How can this command be ran correctly to obtain the isolation level ?

I checked now and in CSQL it works like this:

csql> GET TRANSACTION ISOLATION LEVEL;
=== <Result of GET ISOLATION LEVEL Command in Line 1> ===
       Result
=============
  REPEATABLE READ SCHEMA, READ UNCOMMITTED INSTANCES
Current transaction has been committed.
1 command(s) successfully processed.

However, I need it to work in Python Driver and CUBRID Manager also.

Best regards,

Ovidiu

How to instal CUBRID server with .net aplications in windows 7

2012-09-19T21:50:03-07:00

How to use CUBRID server as a database for .NET applications on Windows server? What are all the components I need to download. What's the order of installation? Are there any tutorial to work with CUBRID? How to write procedures as in SQL? How to connect to CUBRID server from a .net application?

How can you get Server Info using Python Driver ?

2012-09-19T05:38:04-07:00

I want to obtain using the Python Driver the details regarding the CUBRID server version. The MySQL driver offers get_server_info() function to perform this task.

What can be done in CUBRID to obtain the information ?

I saw here:

http://packages.python.org/CUBRID-Python/

That the server_version() function exists for _cubrid connection object alongside many other functions. Why are these functions only working for _cubrid and not for CUBRIDdb also ?

How to find out the Charset CUBRID uses ?

2012-09-19T04:54:59-07:00

Hello,

I want to find out the charset used in CUBRID using SQL. In MySQL it is possible to perform this operation by running "SHOW VARIABLES LIKE 'character_set%'". Is there anything similar for CUBRID ?

Best regards,

Ovidiu

Does Cubrid support Master:Master replication

2012-08-23T04:01:50-07:00

In my use case I require every node to be a master node, accept reads and writes is this possible with cubrid?

As it says on http://www.cubrid.org/key_features

"Reduced hardware costs with the configuration of multiple master database nodes and one or more slave database nodes."

Thanks,

How can you get the query string from a CUBRIDPreparedStatement?

2012-08-21T04:38:57-07:00

According to other websites, you can obtain the query string for a PreparedStatement using its toString method:

http://stackoverflow.com/questions/2683214/get-query-from-java-sql-preparedstatement

For CUBRID however, it only displays:

cubrid.jdbc.driver.CUBRIDPreparedStatement@500b73e5

Is there a way to view the query that it contains (after variables have been binded for example) ?

CUBRID & highload?

2012-08-09T07:36:14-07:00

Hi.

I have a banner network project. I need to INSERT up to 2k rows per second (thats a peak load) in one table and UPDATE up to 300 rows in another.

Table for INSERTs looks like this: id primary key, ip integer, date (date when record was added), user agent, referer, publisher_id (references row in another table), feed_id (references row in another table).

Table for UPDATEs has 12 fields and intentified by primary key id, only one of them (integer counter) is updated.

Also I need to do 2 SELECTs: one on INSERTs table and one on another table with ~10k records.

INSERTs table can have up to 10 million records (this is a log for views/clicks).

Currently I'm using MySQL with Infobright extension, but I already see it doesn't handle load. Scaling MySQL is a problem, so I'm looking for some alternative able to handle such load.

The question is: is CUBRID ready for this? Is it stable?

Creating multiple tables using CUBRID Manager

2012-07-10T04:02:48-07:00

I'm using CUBRID Manager 8.4.1.2019. I right-click on a database and select New Query Editor. I then paste the following SQL

-- Create the ART Repository, version 2.3

-- IMPORTANT:
-- after running this script, ALSO RUN the tables_xxx.sql script for your database (found in the quartz directory)

-- NOTES:
-- for sql server, replace "timestamp" data type with "datetime"
-- for sql server 2000/2005 also replace "date" data type with "datetime"

-- UPGRADING:
-- if you are upgrading, don't use this script. run the scripts available in the upgrade directory
-- run the scripts one at a time to upgrade to newer versions. e.g. from 2.0 to 2.1, then 2.1 to 2.2 etc.

-- if you want to create a new repository in place of an existing one, uncomment the DROP statements
-- you can use a text editor to replace "-- DROP" with "DROP" to accomplish this

-- ------------------------------------------------



-- ART_SETTINGS
-- Stores miscellaneous settings

CREATE TABLE ART_SETTINGS
(  
	SETTING_NAME VARCHAR(50) NOT NULL,
	SETTING_VALUE VARCHAR(2000),  
	PRIMARY KEY (SETTING_NAME)
);

-- ART_USERS 
-- Stores user info

-- ADMIN_LEVEL: 0= normal user, 5 = normal user who can schedule jobs
-- 10 = junior admin, 30 = mid admin, 40 = admin, 80 = senior admin, 100 = super admin

CREATE TABLE ART_USERS
(
	USERNAME    VARCHAR(15) NOT NULL PRIMARY KEY,
	PASSWORD    VARCHAR(200) NOT NULL,
	HASHING_ALGORITHM VARCHAR(20) NOT NULL,
	FULL_NAME   VARCHAR(40),  
	EMAIL       VARCHAR(40),    
	ADMIN_LEVEL        INTEGER,
	DEFAULT_OBJECT_GROUP INTEGER,
	CAN_CHANGE_PASSWORD VARCHAR(1), 
	ACTIVE_STATUS    VARCHAR(1), 
	UPDATE_DATE    DATE  
);

The first table is created, but the second table is not created. The log only says 1'th SQL create operation successfully completed.[0.009 second]. Would anyone know why the second create statement doesn't run?

Does CUBRID include init.d script to autostart Server?

2012-07-12T23:11:48-07:00

Some time ago I've installed CUBRID on Linux using one of the available packages. I've been using it for my personal home page. Once in a while I need to restart the server and this is the point when it gets a little bit inconvenient because I need to run cubrid service start every time manually in order to start CUBRID Service.

Therefore I wondered whether CUBRID installation package already comes with an init.d script to autostart the database server on reboot which I might have missed somehow? If not, is there a plan to include such a script for users' convenience?

CUBRID 64 bit with PHP x86 on Windows 7

2012-07-09T03:46:11-07:00

Hello,

I have installed CUBRID x64 bit and PHP x86 (official release) on Windows 7 64 bit. I tried to manually install the PHP API by adding the driver from here: http://www.cubrid.org/?mid=downloads&item=php_driver&os=windows&ostype=any&php=php53&driver_type=phpdr

I have VC9 thread safe (TS) version of PHP 5.3.10. I added the lines

[PHP_CUBRID]

extension=php_cubrid.dll

to php.ini and the file php_cubrid.dll to ext folder. I have tried with any PHP driver version but it fails to load (php crashes and apache fails to start).

Is there a workaround ?

How to navigate foreign key relationships using the dictionary views?

2012-03-29T08:54:05-07:00

I am implementing a CUBRID integration for jOOQ, and I wonder how I can discover foreign key relationships using the dictionary views. Using the following query, I can discover foreign key columns:

select k.class_name, k.index_name, k.key_attr_name
from db_index  i
join db_index_key k
on i.index_name = k.index_name
and i.class_name = k.class_name
where is_foreign_key = 'YES'
order by k.class_name, k.index_name, k.key_order

Now, how can I discover which columns (or which primary key) is referenced?

How can you safely delete log files ?

2012-06-28T06:23:56-07:00

Hello,

I have the following problem. For some reason, several hundred files with the name xe_lgar001,xe_lgar002,...,xlgar411 files have appeared in the folder for my database named "xe". I have read that they are log files used for backup, but they keep appearing (about 1-2 per day) and each of them is about 40 MB. Also, none of them have disappeared and I even have files since December 16 last year. Is there a way to enable their automatic cleanup ?

Is there any way to safely delete the log files and limit their creation?

How do I move a CUBRID database with LOBS from one server to another, different locations

2012-06-06T04:05:41-07:00

Hi Everyone

I have a production server with an application running and the database there is installed to a certain path.

I have a development server where we have many other applications co-hosted, CUBRID is installed to another location.

I did a backup of the database on the production server which made a level 0 file in the backup folder. I tried to no avail to restore this to my development server, it kept on complaining about the path being wrong.

Eventually I copied the whole database folder from live and overwrote the one on my development server. The problem was that the lob information still pointed to the paths on the production server. I had to also change <dbname>_vinf file to sort out the new paths, the lobs don't understand this.

I had to make a folder of the same path on development and copy the lob sub folder there for the development database to register this.

How should I have done this properly, I have already looked at these documents

http://www.cubrid.org/cubrid_backup_restore

http://www.cubrid.org/cubrid_backup_restore_2

I'm looking for a solution which backs up database_one_name to database_another_name_path if I need to. I have no problem moving the lob data between servers but the database restore must change this relative to my new paths.

I did get what I wanted right but not in a way a general user will be able to handle by themselves, I tasked a junior developer with this task as I felt the GUI tools were quite simple to understand and to use, however it was not that simple.

Is CUBRID less RAM consuming than innodb?

2012-06-10T00:38:27-07:00

Hello,

I have VPS with 1GB of RAM and few low traffic sites on it. But innodb is consuming a lot of RAM and my server sometimes shut down because of that. So I am wondering if CUBRID can help me.

Thank you for quick reply.

How to lock the table?

2011-12-26T00:28:12-08:00

CUBRID provides database level lock like:

cubrid lockdb demodb

But it locks the entire database.

I have already read Isolation Level related question and CUBRID Transaction and Lock guide.

But Isolation Level, as I understand, locks the table only during the transaction. But I have a series of transactions during which the table should not accept any UPDATE/INSERT/DELETE operations, including the time between these transactions.

What should I do to have the table locked until I manually unlock it?

How to pass a custom Object to a Stored Procedure function?

2012-05-26T11:09:41-07:00

hi I have the following function.

CREATE FUNCTION "tblpacientesinsertar"("paciente" OBJECT) RETURN STRING
AS LANGUAGE JAVA 
NAME 'TblPacientes.Insertar(cubrid.sql.CUBRIDOID) return java.lang.String'

I want to pass a custom object class, but I dont know if CUBRIDOID is the right type.

My custom type is public class BoPacientes.

My stored procedure is public static String Insertar(BoPacientes paciente).

C# code looks like:

public BoPacientes Insertar(BoPacientes objeto)
        {
            .....//code code                        CUBRIDCommand com = new CUBRIDCommand();
                        com.Connection = con;
                        com.CommandText = "select tblpacientesinsertar(" + objeto + ")";
                        con.Open();       .......//some code logical       }

The error I receive is:

Semantic: Dev9.DataAccess.Pacientes.BoPacientes is not defined.
select tblpacientesinsertar(Dev9.DataAccess.Pacientes.BoPacientes)

I have a java object called BoPacientes.Class registered in CUBRID.
