Max columns per Table

Posted by:  Kan Kumar ()

Hi, 

I am trying to create a table with more than 2000 columns, but its giving me the following error: 

DBD::mysql::st execute failed: Too many columns at 

I have done my research and found that MySQL database do supports up to 3398 columns per table. 

Is there is any configuration file where I specify the max columns per table? 

Thanks for your help in advance.

Maximum columns per table in mySql 
--------------------------------------------------------------------------- 
Practically,Maximum number of columns per table is 2599. 

Following is the easiest way to deal with your issue (This is tested for mysql5.x on windows xp platform). 
--------------------------------------------------------------------------- 
1)Download mysql administrator from  http://www.mysql.org/downloads/gui-tools/5.0.html 
2)Install it. 
3)Create or access your database using mysql administrator 
4)Using mysql administrator goto startup variable->general parameters->general 
Under general group,untick checkbox called "default storage" 
That is we allow sql-create statement to use the default type. 
5)Restart mysql service 
6)Try your sql statement now.But,as far as I know this works up to 2599 columns only.
