Jianhong,
If you are using execute() as the method to actually execute the sql string (as
opposed to executeQuery()) then you have to make a getResultSet() call to (yep
you guessed it!) get a result set. Once you have a result set it is necessary
to call the next() method to move too the first row and then your getString to
obtain the actual data ( I use getObject actually as it is more versatile) .
Make more calls to next () as required to retrieve other rows
mail again if this doesn't sort it out.
