Getting error in the db2 update statement

Hi all,

In our setup db2 V9.7 with fixpack 4, using partitioned database.

Facing issues in the update statement Getting the error like:

SQL0100W No row was found for FETCH, UPDATE or DELETE; or the result of a
query is an empty table. SQLSTATE=02000

How to overcome this issue?

Thanks,
laxman.
