to get mysql error from php script

[phshss]

Hi,
I am trying read a 2MB ascii file and upload it to mysql database. I was getting FATAL: emalloc() and erealloc() error which is explained in the thread

http://phpbuilder.com/board/showthread.php?t=10336122

I resolved it my increasing memory_limit to 300M. How do i find out the error with regard to php/mysql error messages from script?

I have enabled "error_reporting = E_ALL", still i am not able to get the error details for mysql.

Is there any limit to insert command or Mysql database limit to size?

Thanks in advance.
