allow REPLACE function to accept empty string

The "source-string" for the REPLACE function currently cannot be an empty string, it throws an error. But I can't see any logical or functional difficulty in just applying the replace logic: the "search-string" is not found, therefore the source-string remains unchanged (i.e. empty). I now have to write a case expression to handle the case of the empty string. If, at the time of developing, the test data doesn't have an empty string, chances are this will be forgotten, and the statement will break unexpectedly some time in the future.

    Dear Luc,

    Thank you for submitting this Db2 for z/OS enhancement request. After giving the request another comprehensive review, we have determined that we cannot include it as a candidate in an upcoming product deliverable because it is an incompatible change with low relative value. Consequently, we will not be implementing this request.

    It is more efficient to check for empty string in the host application before invoking the SQL with REPLACE function.

    We appreciate your input to the Db2 for z/OS development team. We also hope that you will continue to submit ideas for improvements as customer feedback is a key component to shaping the future direction of Db2 for z/OS.

    Sincerely,

    Db2 for z/OS Team
