SQL Server 2016 中的表命名约定和策略管理问题

Question

在 SQL Server 2012 中，我有一个策略设置为不允许在表名中使用空格。但是，当我在 SQL Server 2016 中使用相同的策略时，出现错误。

这是条件的代码：

DECLARE @condition_id INT
EXEC msdb.dbo.sp_syspolicy_add_condition @name=N'No Spaces', @description=N'No spaces in table names.', @facet=N'IMultipartNameFacet', @expression=N'<Operator>
  <TypeClass>Bool</TypeClass>
  <OpType>NOT_LIKE</OpType>
  <Count>2</Count>
  <Attribute>
    <TypeClass>String</TypeClass>
    <Name>Name</Name>
  </Attribute>
  <Constant>
    <TypeClass>String</TypeClass>
    <ObjType>System.String</ObjType>
    <Value>% %</Value>
  </Constant>
</Operator>', @is_name_condition=4, @obj_name=N'% %', @condition_id=@condition_id OUTPUT
SELECT @condition_id

这是策略的代码：

DECLARE @object_set_id INT
EXEC msdb.dbo.sp_syspolicy_add_object_set @object_set_name=N'Table Names_ObjectSet', @facet=N'IMultipartNameFacet', @object_set_id=@object_set_id OUTPUT

DECLARE @policy_id INT

GO

在 SQL Server 2012 和 2014 中，这给出了预期的结果：

CREATE TABLE [test table]
(Id INT NULL)

“SQLSERVER:\SQL\LSRSQL07\SQL2012\Databases\test\Tables\dbo.test table”违反了策略“Table Names”。此事务将被回滚。策略条件：'@Name NOT LIKE '%[- .]%' AND @Name NOT LIKE '%[^A-Za-z0-9[_]]%'' 策略描述：''附加帮助：''： '' 语句：'CREATE TABLE [测试表] (Id INT NULL)'。消息 3609，级别 16，状态 1，过程 sp_syspolicy_dispatch_event，第 65 行 [批处理开始行 48] 事务在触发器中结束。该批次已中止。

如果我运行以下代码，则不会出现错误：

CREATE TABLE [testtable]
(Id INT NULL)

但是，如果我CREATE TABLE在启用策略的 SQL Server 2016 上运行任何语句，我会收到以下错误：

“SQLSERVER:\SQL\LSRSQL07\SQL2016\Databases\test\Tables\dbo.testtable”违反了策略“表名”。此事务将被回滚。策略条件：'@Name NOT LIKE '% %'' 策略描述：'' 附加帮助：''：'' 语句：'CREATE TABLE [testtable] (Id INT NULL)'。消息 515，级别 16，状态 2，过程 sp_syspolicy_execute_policy，第 69 行 [批处理起始行 44] 无法将值 NULL 插入列“target_query_expression”、表“msdb.dbo.syspolicy_policy_execution_history_details_internal”；列不允许空值。插入失败。该语句已终止。

在 SQL Server 2016中，无论是否通过条件，我都无法创建任何表。

这是 SQL Server 2016，SP1，CU3。

对此有何想法？

编辑：我需要评估模式为“更改时：阻止”

Answer 1

在 SQL Server 2016 SP1 CU2 实例上测试脚本，如果评估模式设置为“更改时：阻止”，则该策略有效。（有一个错误，它不允许您评估使用特定方面的策略）。

同时，如果您只使用表名策略，您还可以尝试使用“Table Option”方面而不是“MultipartName”，具有相同的配置 ( @NAME NOT LIKE '% %')。
