Analyze SQL Query before Running

Hi,
Is there a way for MySQL to verify that a SQL statement is syntactically and logically correct before running the actual statment? I have a few insert statements that allow form data and I want a way to verify that the SQL is robust and will correctly execute before running the actual query (I'm using PHP also).

You can put EXPLAIN in front of it (assuming a SELECT statement).  That will highlight systactic errors (but not logic errors - you'd probably need to see the results to verify those).

An example:

mysql> select * from doesnt_exist;
ERROR 1146 (42S02): Table 'test.doesnt_exist' doesn't exist
mysql> explain select * from doesnt_exist;
ERROR 1146 (42S02): Table 'test.doesnt_exist' doesn't exist

It will catch all SQL syntax errors or invalid table/column errors.

If you use MySQL query browser it will colour code the query as you construct it, so keywords turn blue, table names red etc.  So you could tell by looking at the colours of the text to see if your syntax is valid.
