You can just append .to_sql to the end of your call. That will give you the SQL query.

I used gcc compiler, MySQL Server 5.0
When I use a long length string as a value to insert or update or select or delete, system doesn't work. No error comes. So I could not find the error.
A part of my code is this :
mysql_query(conn, sql);
Yes, it's possible if you use the C driver for MySQL.

I am using the Business Objects Data Integrator tool and I want to run it from the command line so I can setup some automated unit testing.
Does anyone know if there is a command line to run it?

Perhaps pp65-66 are what you want? I confess to never having tried it myself, but it looks like it should work. :)
