There is no general answer to whether or not to sort in DataStage or the DB. The only good answer is to empirically test it and choose the faster option. If the DB Server is heavily loaded and the DataStage machine is well-dimensioned with fast disks and memory it might well be much more efficient t...

try

Code: Select all

IF  IsNull(To_tfr.dock_id) THEN '99' ELSE IF To_tfr.dock_id ='  '  THEN '99' ELSE To_tfr.dock_id

Are you doing pure inserts or upserts/updates as well? Can you turn on rejects from that stage and see what the SQL error code is?

It is a bit difficult in this case to localize the error since the full code is not there and the cause might be in those parts removed.

I usually go to the director, in the menu bar go to View and turn off the "show folders" then sort the list on "status". Note that this can take a while in a big project and you should turn on the "show folders" when you are finished to improve director performance.

If you have the 8.5 Software, then all you need to do is look at the PDF documents that delivered with it for the instructions.

You can't expect the forum members to guess your table name, column names, and data contents. Or the database type and stage you are using and any or all of those will play a role. In addition, the complete error message would also help in helping you.

I don't understand some of the difficulties here. Can you, from the CMD prompt, execute your batch (without the CLS so you can see the messages) and get your job running?

If you don't have write permission to the default configuration file directory, save the 1-node file anywhere on the machine (i.e. "/tmp/1node.cfg") and then reference that location in your runtime parameters.
