FIX: AFTER DELETE triggers occur in the wrong order in the ON DELETE CASCADE action chain in SQL Server 2014 or 2016

Applies to: SQL Server 2014 DeveloperSQL Server 2014 EnterpriseSQL Server 2014 Enterprise Core


Consider the following scenario:
  • In SQL Server 2014 or 2016, you have several tables, each of which has a PRIMARY KEY constraint specified.
  • You create a cascading chain for those tables by using the FOREIGN KEY constraint together with the ON DELETE CASCADE action.
  • You create an AFTER DELETE trigger for each table.
  • You delete a row from the parent table. This triggers the AFTER DELETE triggers and the ON DELETE CASCADE action chain.
In this scenario, the triggers may occur in the wrong order.
