Workspace Db2 for z/OS

Always drop indexes related to unique constraints

When dropping a unique constraint or a primary key that has been defined on a table in an explicit (universal) table space in DB2 10 NFM, the related index is not dropped if the index was explicitly created too. However, when the index or the table space was created implicitly, the index is dropped each time the constraint is dropped.
It would be logical that the index related to the constraint is dropped at all occasions.

    Dear Ludovic.,

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

    The work around at the moment is that the you will need to manually drop the index if it's not desired.

    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
