The SA_LABEL_ADMIN.DROP_LABEL procedure drops the specified policy label.
An "Invalid Label" error will be reported if the label is subsequently referenced in data rows, user labels, or program unit labels after it is dropped.
Use this procedure only when setting labels. If you accidentally delete a label that is in use, you can restore the label by disabling and then re-enabling the policy.
