insert warning - how to look at

[Sydney Puente]

Hello,

I have an application which is inserting rows into a Mysql 5.024 db.
It seems to stop when an insert generates a warning.
when I insert the suspect line on the mysql commandline I get this: 
Query OK, 1 row affected, 1 warning (0.05 sec)
Other inserts that succeed seem not to generate warnings when I make the 
insertion on the command line.

What can I do to troubleshoot this?
For example how can I access the actual warning?

TIA

Syd
