That was one of my concerns.  Although, I still am not quite sure what I
should do instead.  Any hints?

SELECT COLUMN_NAME FROM SYSCOLUMNS WHERE TABLE_NAME = 'TAB1' and
TABLE_SCHEMA='KULACK'                                            ORDER BY
ORDINAL_POSITION would be useful too 8-)

In actuality, its hard to say which is faster to execute, but
this one ends up being MUCH nicer because it can be a SINGLE prepared
statement, and if you replace 'TAB1' and 'KULACK' with your
parameter marker (question mark), all you do is setString() for each
and execute it.
I.e. you don't prepare and execute every time, you prepare 1 time,
and setString(), setString(), execute() every time.
This is a bigger savings.
