Hi,

I am trying to just get the value of a column in a DB that stores an int. The value is not null. I have tried both using a column name and index number and with both I get a SQLException error. This is the code:



The line I am getting the error on is:




Anyone have an idea as to why this would be happening? All help would be appreciated.

Michael,
JDBC requires you call rs.next() before rs.getXXX(). A typical idiom is:

Note that we have a forum just for JDBC questions up near the top of the forum list. I'll move this for you.

Thank you very much, sometimes I shock myself with how I overlook small things! I new that you had to do rs.next() and for some reason refused to think of that...Thank you very much for your help!
