In PHP, you can see the error message as follows:
$result = mysql_query($sSQL) or die ("<br>".mysql_error()
Just change it to write that mysql_error() to a file instead and that'll do
it. So, something like:
$result = mysql_query($sSQL) or die ( log_error(mysql_error()) );
where you create that function log_error to write to a file.

Subject: Re: How to Log Warnings and Errors from queries
as you know mysql gives you an error to check your sql syntax when it
doesn't understand a query but does not log it , but you can have your
application (php, perl, etc ) accessing mysql to log any bad/malformed
