Problems with java and mysql error: 1064

Hello,
I have been struggling with the following java code for a day. I ALWAYS get the following error code : 1064 and I just can't figure out why. I am trying to insert data into a mysql table.
Can anyone please help?
Thanks in advance,
Julien.

1064 is a query syntax error I think? Your SQL statement is big and complex to build. I'd recommend you swap to using a PreparedStatement, make things easier for yourself.

Thanks a lot Paul!
My code was not very clean. I changed to a prepared statement and it now works.
