Reply with quote

Hi,

I have a partial key populated and I am making a qualified GU call. But looks like it is still reading the database from the top. Is there any way that I can read the segment from the partial key which I have ?

Please advise.

Load the high level portion of the key - then initialize the low order key fields with low-values. Make your operator > (greater than) - qualify your SSA and do a GN. An unqualified GU will always position you at the beginning of a database.
