MYSQL Error - How can I log the Query (not only _error_messge()) - El Forum - 06-13-2010

Hi Guys !
I am using active record for the query.
I was wondering if there is any way logging the query which resulted in an error.
_error_message()
_error_number()
Bother return to less information for the log. I need to know the exact query with the values, which caused a problem and I am struggling to log them.
This information is usually shown on screen when DB debugging is enabled.

Ah that's a nice trick.
That's exactly what I needed. Thanks

You may have some use for:
Code:
$this->output->enable_profiler(TRUE);This will append to the bottom of the page execution time, request array, DB queries, and session variables.

Thanks for the info. This was already enabled, but I just needed to log the query for error purposes later in live.
PS: I am a little confused with mysql errors. When a user is trying to log in and all the insert/update etc. commands are executed. Some of them might fail for what ever reason, should I show this as a fatal error with show_error() and terminate the application or should I just log the error, but that means checking the success of EVERY query. Is this practical ?
But then if lets say the session table wasn't updated properly or the user tables, this is a really major problem. Is it better to terminate the application in this instance ?
I am currently trying to implement some DB exception etc. and I am really confused how to do the design and when exactly to call what errors.

It might NOT be practical no but thats when you can use enable_profiler so you see right away if it failed or not.

Hi !
Yes, but once the site is live I have to disable the profiler. What if such an error occures during the live time.
I guess I have to check every select,update,insert,delete statement for errors...
