Re: scrollable result sets

Hi Joe,
 
Thanks for your response, I haven't had a chance to try your
recommendations, but hopefully will tomorrow.  I figured out a
workaround, but would like to figure out why it's not allowing me to
reposition.  Your tip of checking the methods should help!
 
Instead of the following: 
> I can process the result set once, but any attempt to reposition the
> cursor yields null values.

I should have said any attempt to reposition the result set yields a
boolean value of false.  So basically it's telling me that I can't
reposition the result set.

    Hi Nancy,

    I tend to stay away from stored procedures, although you wouldn't
know
it at the moment; I'm currently involved in converting several hundred
SQL
Server SP's to DB2.

    I would expect your code to work.  The primary thing that ocurred
to me
is that holdability may be ResultSet.CLOSE_CURSORS_AT_COMMIT.  That
still
may be the issue.  If so, use

Connection.prepareCall(String sql, int resultSetType, int
resultSetConcurrency, int resultSetHoldability)

    You can check your ResultSet with the ResultSet methods
getConcurrency()
and getType(), and the Statement methods  getResultSetConcurrency(),
getResultSetHoldability() and  getResultSetType().

    But this:

> I can process the result set once, but any attempt to reposition the
> cursor yields null values.

doesn't make sense to me, unless the program is resetting the variables
to
null beforehand.  Do you get any warnings or exceptions?  What is the
boolean return of your positioning call?
