Assume that you use the Policy-Based Management policy to manage Microsoft SQL Server 2016. After you install the Cumulative Update 2 (CU2) for SQL Server 2016 Service Pack 1 (SP1), the policy may function abnormally. For example, you have the policy to evaluate whether the name contains specific characters when you create a new stored procedure. After you install CU2, even if the name is valid, you may still not able to create the stored procedure, and you receive an error message that resembles the following:
Cannot insert the value NULL into column 'target_query_expression', table 'msdb.dbo.syspolicy_policy_execution_history_details_internal'; column does not allow nulls. INSERT fails.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
