RE: Result Set Size

["Xu, Weining" <Weining.Xu@xxxxxxx>]

Sudha,

Thanks again,  I have not done this before.  Could you send me the sample
code? That will be a big help.

Regards,

Wayne

Yes Wayne, by setting up a cursor.  But we do this within the program that
returns a result set, using the Multiple occur DS.  We keep track of how
many we sent and read the next 1000 from there.  We use the key fields, if
they are necessary and either way, this works out efficiently.  There is a
return parameter to the Java that tells if any more records are available in
the file or not.  Accordingly, the Java can either make multiple calls at
the same time or make the call when the user requests for it, to avoid
traffic overflow.  Please let me know if you need any sample code and I will
be only happy to help.

Thanks,
Sudha

Thanks, Sudha, say if I set the count as 1000, do you know how to get the
next 1000 and so on?  by set up a cursor?

Wayne,
We use the Stored procs for this purpose.  The Set Result Set has a number
of rows clause that helps monitor number of rows to be returned.  (Stored
procs also use JDBC driver.)

        C/EXEC SQL SET RESULT SETS ARRAY :outrec FOR :count ROWS
        C/END-EXEC

Here the count can be whatever you want it to be.

Hope this helps.
Thanks,
Sudha

Hi,

We have a Java batch program running on AS/400 by using native JDBC driver.
The program have various random exceptions when the data are processed up to
about 25000 records.  The result set returned about 50000 records.

We would like to reduce the number of rows returned by JDBC driver Result
Set.  How to specify the number of rows from: rs =
stmt.executeQuery(aSQLQuery) ?
For example first 1000 rows.  Then how to get the next 1000 rows?

Thanks a lot.

Wayne
