Welcome to JavaRanch

At a quick � second look at your SQL I can't see a problem with it; I presume it runs all right from the command line? A NullPointerException (NPE) doesn't occur in SQL code at all; it occurs in the Java code which you haven't provided. Go to the beginner's forum and do a search for NullPointerException and you find threads like this one, which has links to older threads. Go through them and you will know more about NPEs, to help you solve your present problem.

I agree with Campbell - this problem is not caused by SQL.

Also, NPEs are more of a beginner's problem (although even experienced programmers can be haunted by them ).
Moving there.
