SHOW CREATE TABLE Support

2012-02-21T12:08:20-08:00

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

Script lose connection with cubrid broker.

2011-01-01T00:31:06-08:00

Hi everybody. Sorry for my english.
I don't know, how it's work. But when i use long time connection to database with php. Cubrid (may be cubrid extension for php?) drop connection and all queries not work.

You can reproduce this by install cubrid, add php extension, create database and run next script


<?php

set_time_limit(0);
$user = "dba";
$password = "1111";
$host_ip = "localhost";
$host_port = 33000;
$db_name = "test";

$count_of_units = 1000000;

if (!($con = cubrid_connect($host_ip, $host_port, $db_name, $user, $password)))
{
    echo 'Connetion error';
    echo cubrid_error_msg();
    exit;
}
for($i = 1; $i <= $count_of_units; $i++)
{
    $rnd = rand(1,1000);
    $req = cubrid_execute($con, "insert into tbl_test (`some`) values ({$rnd})");
    if($req)
    {
         cubrid_commit($con);
    }
    else
    {
         echo 'Bug: ';
         echo cubrid_error_msg();
         break;
    }
}

cubrid_disconnect($con);

Table tbl_test structure in attachement.

After over 500000 queries connection freezes. I think, that is associated with some brokers' settings, but i not sure. I use all by default.

configuration 1:
windows, xampp 1.7.3, cubrid 3.0, php 5.3.x cubrid module from official site (vc6)
configuration 2:
linux, apache 2.3, php 5.3.3, cubrid 3.0, php cubrid module from pecl.

Limit operation resource for users

2010-06-13T17:31:07-07:00

Hi,
for a shared enviroment (like hosting one and not) will be vital to have limitation for users resource.
For Mysql is possible limit select, update, connection in a hour but is only a rudimental thing and not so "serious". Immagine this :
I am a DBA and I want to limit my 50 users to not kill my db and limit to 30 select hours all users.
I think to solve all problem with this limitation
Yes but ... 3 of my users join 4 tables with a result of 10000000 records because are not expert with SQL or for a wrong select using ONLY a connection and 1 query and my db is hanged for a while
The idea is limit the resource for users that are using in the same time the db resource.
The best will be to have a dynamic resource with a % for each users like a thread manager for linux
But a max time for operation in millisecond will be a great thing to have a better security and I think more easy to implement.

Error while using CMT to port from MySQL to Cubrid

2010-10-04T18:40:16-07:00

Hi,

I am using CMT to port database from MySQL to Cubrid. More precisely I have tried to port the Joomla! database from MySQL to Cubrid using CMT.

After the migration was finished the resulted database was incomplete. All tables that had DATETIME columns weren't imported due to errors. In MySQL some records had '0000-00-00 00:00:00' and weren't imported due to CMT being unable to transform them to '0001-01-01 00:00:00'.

I suppose that CMT doesn't handle coorectly MySQLs' empty values defaulting to 000....
Please note that I have tried in Step 5: Object mapping to set default value to '0001-01 ...' but that didn't solved the problem.

I have attached the database dump and error log saved from CMT interface.

Platform:

java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing)

Distributor ID: Ubuntu
Description: Ubuntu 10.04 LTS
Release: 10.04
Codename: lucid

Linux ubuntu 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 22:02:19 UTC 2010 i686 GNU/Linux

UI errors in CMT

2010-10-04T19:03:59-07:00

Hello again,

In "Step 3: Migration Database Object Selection", Every time when I try to press NEXT, gives the message 'Exist database name "" is invalid!'. I fiddled with the UI, pressing next/previous, (un)checking checkboxes, restarting whole application and somehow I succeeded to run the wizard - see screenshot1.png

Strangely, after several restarts, now it works and the Next button doesn't become grey anymore, but I have noticed that in the top of the window there is still the error message mentioned above appearing in the next screen (Step 4) - see secreenshot2.png

Also in screen 2 (after pressing Next in screen 1) appears an error "Select a database connection in the list". Could this may be related to validation functions being called at an inappropriate moment?

Regards,
Cristian

ActiveRecord column type binary

2010-10-14T16:21:49-07:00

Hi,

According to API http://api.rubyonrails.org/classes/Acti ... d-i-column supported column types for a table are :string, :text, :integer, :float, :decimal, :datetime, :timestamp, :time, :date, :binary, :boolean.

While trying to use :binary, it does not work, the generated query looks like this:
CREATE TABLE books8 (id int primary key, bin_col varbit(32768) NOT NULL)

Complete example:

require 'rubygems'  
require 'active_record' 
require 'pp'

ActiveRecord::Base.establish_connection(  
	:adapter => "cubrid",  
	:host => "localhost",  
	:database => "demodb" ,
	:user => "dba"
 )
 
ActiveRecord::Schema.define do
	create_table :books8 do |table|
		table.column :bin_col, :binary, :null => false
	end
end

This happened while using Ruby 1.8.7 on Windows XP with Cubrid 3.0 stable. Adapter was gem cubrid-0.64.

Unable to load dynamic library cubrid.so - libcascci.so.8

2010-12-08T13:50:16-08:00

Hello,
I installed Cubrid 2.2 on my server, which has PHP 5.2.
I copied the cubrid.so into my extension directory (/usr/lib/php5/2006...), but when I restart my Apache, I get the following error message :

Someone...
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20060613+lfs/cubrid.so' - libcascci.so.8: cannot open shared object file: No such file or directory in Unknown on line 0

I guess it's because the Cubrid extensions (including libcascci.so.8) are not in the same directory as my PHP extensions.
So how can I get Cubrid to work properly ?
Sorry for my approximative english, and thank you for your answers.

Quizland March 2011 question 10

2011-03-30T21:44:19-07:00

Good day,

I have a question about Quizland March 2011 question number 10. I think I have the correct query for what I think I should have done, but I'm not sure I have understood the question well.
It seems to me that the query result should be a single result - a string where index names are concatenated with a comma and the indexes within this string are sorted via their names in ascending order. Should it also include system table names?

It would be nice if the question could be updated with a hint of how many indexes should there be in the result.

Thanks.

Cubrid multicore sql optimisation

2011-10-03T10:40:25-07:00

Hi ,

Can cubrid engine automatically optimize sql execution so that it uses all cores on a multicore cpu ?

For example sql performing computation on large datasets (19 milion rows) have both IO and CPU workload, overlapping CPU with IO may reduce querry execution time.

Please post any comments on this or some links to cubrid documentation that adds more clues for this area.

Thanks,

Enkidu.

Precompiled cubrid.so/pdo_cubrid.so on Ubuntu Natty

2011-06-13T15:40:52-07:00

Hi,

there's a problem with precompiled php modules for PHP.

When trying to load them (by adding to php.ini or /etc/php5/conf.d/) for:

cubrid.so I get a warning:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626+lfs/cubrid.so' - /usr/lib/php5/20090626+lfs/cubrid.so: undefined symbol: executor_globals_id in Unknown on line 0

All good, but cubrid_* functions are not available anyway. After googling, it looks like the module was pre-compiled without ZTS enabled or something like that, while on Ubuntu it's vice-versa.

pdo_cubrid.so loads without warning, but again, functions are not accessible.

My environment:

apt-cache policy nginx-light php5-fpm | grep Instalat  Instalat:   5.3.5-1ubuntu7.2  Instalat:   0.8.54-4cubrid --version

cubrid (CUBRID utilities)

CUBRID 2008 R4.0 (8.4.0.0196) (32bit release build for linux_gnu) (Apr 29 2011 00:21:30)

uname -ri

2.6.38-8-generic i386

So I had to re-compile the cubrid.so using PEAR, worked fine now. (My cubrid.so here)

P.S.: Having a PPA for Ubuntu/Debian, would be really cool.

DB Files

2011-08-17T08:20:35-07:00

Hi,I have several questions regarding the DB files. When creating a DB in Cubrid Manager, is there only one file containing the whole DB? If not, what files conform the DB?Why the files created after a DB is created does not have extensions?Does the log files in a DB stored in the same file of the DB, if not which files are for the logs?Could you tell me which files are created after the DB is created and what are they for?
