Javaranch tip:

If you are going to post more than a line or two of your code, wrap that
code in a set of UBB Code tags.
Doing so will help to preserve your code's indenting, making it easier to read.
If it is easier to read, more people will actaully read it and you will
stand a better chance of getting help with your question.

I'm going to move this to our JDBC forum where the database gurus hang out.
Good-Luck

Sachins,
Which line of code throws that error?

Also, does the query work if you run it at the database command line?
