BUG #: 56102 (SQLBUG_70)
In certain circumstances, when you perform the following steps in the exact order listed, a handled access violation (AV) may occur:
  1. The existing primary key constraint is dropped from a table.
  2. An attempt is made to add a new primary key constraint to that same table.
  3. The attempt to add the new primary key constraint fails with the following error because of the existence of duplicates in the column (or columns) on which the key is being added:
    Msg / Error 2627 Violation of %s constraint '%.*s': Attempt to insert duplicate key in object '%.*s'.
  4. An attempt is made to run the sp_execute function against that table to delete a row or rows from the table.
Before adding the new primary key constraint, make sure that there are not any duplicate or null values in the column (or columns) on which the key is being added.
Microsoft has confirmed this to be a problem in SQL Server 7.0. This problem has been corrected in U.S. Service Pack SP2 for Microsoft SQL Server 7.0.
