Can't use shard with PHP

2013-05-20T06:08:57-07:00

Hello.

I try to insert data into shards with PHP, but connect using PHP PDO with error:

Error: SQLSTATE[HY000] [-10100] CAS, Unknown error
Code: 4294957196

PHP code:

try {
$db =new PDO('cubrid:dbname=shard1;host=localhost;port=45511', 'shard', 'shard123' );
echo "PDO connection created ok!"." ";
} catch(PDOException $e) {
echo "Error: ".$e->getMessage()." "."Code: ".$e->getCode()." ";
}

But with JAVA example ( http://www.cubrid.org/manual/91/en/shard.html ) everything works fine. JAVA code:

connection = DriverManager.getConnection("jdbc:cubrid:localhost:45511:shard1:::?charSet=utf8", "shard", "shard123");

If in PHP i use port 30000 - everything works fine, data inserted, but without sharding.

What's the problem?

Italian translation

2010-06-12T18:15:21-07:00

Hi,
Browsing the code I see the language directory where is present english and Korean... eventually do you need an italian translation of it (with a bit of time) ?
(Sorry I wrote in this section because in Internazionalization is not present a general index but only language specific code)

Cannot connect to database

2013-04-23T15:26:58-07:00

PHP fatal error uncaught exception PDO exception with message: could not connect to database.

I'm running Ubuntu 12.04 and have downloaded all the php drivers, etc. Just says unable to connect. Other than this, I believe I can run the script.

I'm running the command line: php5 ./imap_redbean.php

and I'm getting the above error.

What is the purpose of first volume when creating database?

2013-03-09T22:35:22-08:00

Hi,

What is the purpose of first volume when creating database which is generic volume? Why it is not data volume?

What is the usage of generic volume? It means it can hold both data and index?

Difference between checkpoint_interval_in_mins and page_flush_interval_in_msecs?

2013-03-10T01:27:59-08:00

Hi guys,

I'm confused about difference between checkpoint_interval_in_mins and page_flush_interval_in_msecs? They are both writing dirty pages in buffers to data volume at specific interval.

Does table partitioning cause index partitioning too?

2013-03-09T02:03:32-08:00

Hi,

Does table partitioning cause index partitioning too? Or we have one big index and bunch of small data tables

I'm asking this because in PostgreSQL we should create index for each partition separately.

Partition Pruning and parametrized query

2013-03-09T01:53:46-08:00

hi guys,

Partition pruning section says:

In versions lower than CUBRID 9.0, partition pruning has been executed at the query compiling stage. However, in version of CUBRID 9.0 or higher, it is executed at the server side at the query execution stage

Does this mean we can not benefit partition pruning when using parametrized query because at compile time arguments are not available?

Is it possible to define conditional unique constraint

2013-01-23T18:18:44-08:00

Cubrid unique constraint doesn't allow multiple Nulls, But in my case I just want to enforce unique constraint to all no null values, that is for the following schema

create table t (

ID_ varchar(64) not null,

EMP_ID varchar(64) not null,

COM_ID varchar(64),

NAME varchar(64) not null

);

alter table t

add constraint UNIQ_T_EMP_COM

unique(EMP_ID , COM_ID );

these inserts should not violate unique constraint
insert ('12', '23', null, 'blah');

insert ('13', '23', null, 'blah');

Is it possible to define that kind of unique constraint? Please point me out.

Thanks

Stuck installing Cubrid on FC15

2012-02-29T12:24:55-08:00

Hi there,

Want to try Cubrid but.. I cant get the PDO driver to work:

When I run php-cli I get:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/pdo_cubrid.so' - /usr/lib64/php/modules/pdo_cubrid.so: undefined symbol: php_pdo_register_driver in Unknown on line 0

I have no clue what this means. I installed the PDO version as described and put the extension .so ref in my php.d/cubrid.ini file.

Any ideas?

Executing multiple statements

2012-12-24T00:30:21-08:00

Is it possible to execute multiple statements using the Statement.execute() method, and access the statement results using the Statement.getMoreResults() method? e.g.

String sql="select * from table1 ; select * from table2;";

PreparedStatement ps = conn.prepareStatement(sql);

ps.execute();

Resultset rs = ps.getResultset();

while(ps.getMoreResults()){

rs=ps.getResultSet();

}

PreparedStatement getUpdateCount issue

2012-12-29T03:21:12-08:00

I have the following code.

String sql="update table1 set col1=1; select * from table2; select * from table3";
 
PreparedStatement ps = conn.prepareStatement(sql);
 
ps.execute();
 
Resultset rs = ps.getResultset();
int updateCount = ps.getUpdateCount();

while(ps.getMoreResults() || ps.getUpdateCount() != -1){ 
	rs = ps.getResultSet();
	updateCount = ps.getUpdateCount();
}

It seems like the getUpdateCount method doesn't return an updated value if a select statement follows an update statement. I would expect the updateCount variable to have -1 at the end of the loop but instead it has the result from the update statement.

demodb documentation

2012-04-14T21:54:09-07:00

Hi,

you are providing a sample database 'demodb' with your installers as well with your virtual machine images. This raises the expectations to have a quick and easy posibility to start and get issue the first queries within a few minutes. But in the end I needed four hours (also caused by other documentation issues posted in this forum).

You do not provide the user with the necessary information to access it (or do not provide links to it). It took a long time to find out, that not my JDBC connection data was wrong, but that I had to start the demodb explicitly (cubrid server start demodb) though the CUBRID service was running. Finally I found user and password ('dba', <empty>) only through a forum question related to accessing a custom instance, not by regular documentation. You can save evaluators a lot of time providing a short 'Getting started with demodb' page or so.

Regards,

Volker

case insensitive search in varchar fields

2012-10-10T05:01:45-07:00

Hi,

I have the following table:

CREATE TABLE "users"(
"user_id" integer AUTO_INCREMENT,
"user_name" character varying(4096) NOT NULL UNIQUE,
"user_email" character varying(4096) NOT NULL UNIQUE,
"user_nickname" character varying(4096) NOT NULL,
"user_firstname" character varying(4096) NOT NULL,
"user_lastname" character varying(4096) NOT NULL,
"user_points" integer DEFAULT 0,
"user_rank" integer DEFAULT 0,
CONSTRAINT pk_user_user_id PRIMARY KEY("user_id")
);

I want to be able to search users like this:

SELECT
    users.user_name AS username,
    users.user_nickname AS nickname
FROM
    users
WHERE
    users.user_name LIKE 'Joh%' OR users.user_nickname LIKE 'Joh%'

Questions:

1. Is there a better way to do this?

2. How can make this operation case insensitive? If I write 'joh%' I get no result.

Thanks,
Dragos

SHOW CREATE TABLE Support

2012-02-21T11:08:20-08:00

I need to extract the table definition from SQL, is there support for this? In MySQL I would use SHOW CREATE TABLE.

I looked into the documentation, but I only found support for SHOW CREATE VIEW functionality.

I've found out that for 8.4.0 is not supported, but I cannot find the "New features" for 8.4.1. Could you please point out the correct link?

Thanks,

Cristian

CUBRID Manager database designer

2010-12-28T13:56:25-08:00

Adding an new designer would be a great addition to the CUBRID Manager. This, including reverse engineering a database, drag & drop tables this by using mouse would be very useful and none of the existing database provide such a tool by default.

Have a look at this commercial tool for MySQL - EMS MySQL Manager (http://www.sqlmanager.net/).

CUBRID 8.4.3.0001 stable

PDO_CUBRID 8.4.3.0001 stable

Server version:

Cubrid Version: CUBRID 2008 R4.3 (8.4.3.0150) (32bit release build for linux_gnu) (Nov 23 2012 12:16:52)

Broker Version: VERSION 8.4.3.0150

I installed PDO_CUBRID following these instructions: http://www.cubrid.org/wiki_apis/entry/build-cubrid-php-driver-on-mac-os-x-through-pecl-using-cci-driver

It seems to me there is likely a problem in the versions: PDO_CUBRID is 8.4.3 and the CCI driver is CUBRID-CCI-8.4.1.4009-x64.macosx.tar.gz

The only CCI driver version available for OS X is 8.4.1:

http://www.cubrid.org/?mid=downloads&item=cci_driver&os=mac%20os%20x&cubrid=8.4.3

but there is not a PDO_CUBRID version for 8.4.1:

http://pecl.php.net/package/PDO_CUBRID

Instructions for building CCI on OS X (http://www.cubrid.org/wiki_apis/entry/building-cubrid-cci-api-on-mac-os-x) are not useful for 8.4.3 because I can't find the corresponding SVN branch.

How should I get PDO_CUBRID working on OS X?

how to setup sharding

I read the document but I can't still figure out how to use sharding. Can you please spread some more info about it, a step by step guide, or what happens when I want to add another shard, any sharding configuration strategies, etc.

strange bug that stops the database

2012-09-22T00:45:48-07:00

Hi,

I am working with CUBRID and python CUBRID in a W7 environment for over a month and this is the first time when I encounter a problem like this. I can reproduce it all over again.

I have created a view that extracts data from 2 tables:

SELECT
    actions.action_id AS action_id,
    actions.user_id AS user_id,
    actions.page_id AS page_id,
    actions.action_type_id AS action_type_id,
    actions.action_when AS action_when,
    users.user_name AS username,
    users.user_nickname AS nickname
FROM
    actions LEFT JOIN users ON actions.user_id = users.user_id
ORDER BY actions.action_when ASC

In the users table are 3 records:

In the actions table are 5 records:

And here is the view with 5 records:

Now, anytime I want to query the view like this:

SELECT username, nickname FROM actions_users WHERE page_id = 100274

the database stops working:

1. from CUBRID Manager:

2. from web application via python driver

After that, I have to manually start the database, then it works for a few queries and stops working again. An important thing to be considered is that this happens mostly after an INSERT operation in the actions table - the sql can be viewed in the above capture.

Right now I don't know how to handle this. Any ideas? I tried a lot of things: delete view and recreated with a different name, rename columns but the same result: when query the view the database stops.

If is necessary I can provide the full database schema + data and also the SQL commands executed through the python driver.

Thanks a lot,
Dragos

unload/load issue

2012-09-11T00:54:14-07:00

After a successful unload/load operation I noticed something strange regarding the order of the records in a table:

- from development server

- from the production server

The records come in the reverse order. Why is that?

Thanks,

paging records

2012-09-11T01:16:06-07:00

What is the best way for paging records, is there something built in CUBRID?

What I need is a DIGG style pagination like here - http://metropotam.ro/La-zi/. There is a python library the implements DIGG pagination but in order to use that with CUBRID I have to do 2 queries instead of one:

1. first count and find out how many records are

2. instantiate digg pagination in python and get the range (e.g. is page number 3 and record from 201 - 300 using 100 records per page)

3. call database again using LIMIT

Is there another solution?

Thanks,
Dragos

move full database using unload/load from CUBRID Manager

2012-09-11T00:47:09-07:00

Hi,

What I am trying to do is to move the database from the development server to production server using the interface provided by CUBRID Manager. Here are the steps:

1. stop both databases from both development and production servers

2. unload all schema and data from development database, 2 files are created: metropotam_objects and metropotam_schema

3. move files to production server; give permissions

4. load from files (of course, the database is stopped!)

5. i got the following error message

If I erase all the tables and views then the load works. Also, if a create an empty database the load works. But I don't think that this is the right way to do it.

What is the right way to move a database from a server to another using unload/load? Is there another approach?

Thanks,
Dragos
