触发募集错误，防止删除和审计尝试

我试图创建一个触发器，它做了三两件事：1。防止数据删除在特定表 2.为用户生成的错误信息3.将尝试删除的数据与来自SQL的会话信息一起记录。触发募集错误，防止删除和审计尝试

这是我到目前为止的代码：

CREATE TRIGGER [dbo].[MyTable_prevent_delete_and_audit] 
ON [dbo].[MyTable] 
INSTEAD OF DELETE AS 
     BEGIN 
      DECLARE @SESSIONINFO nvarchar(200) 
      SELECT @SESSIONINFO = (RTRIM(LTRIM(CAST(login_time as nvarchar(20)))) + ' ' 
      + RTRIM(LTRIM(hostname)) + ' ' + RTRIM(LTRIM(program_name)) + ' ' 
      + RTRIM(LTRIM(cmd)) + ' ' + RTRIM(LTRIM(loginame))) from sys.sysprocesses WHERE spid = @@SPID 
      INSERT INTO [dbo].[MyTable_AUDIT] ([Field1],[Field1],[SESSIONINFO]) 
      SELECT [Field1],[Field1],@SESSIONINFO FROM deleted 
      RAISERROR ('Removing MyTable entries prevented by trigger. Contact your administrator', 16, 1) 
     END 
     RETURN 
GO

上面的代码能够防止删除，引发错误的用户。但是，任何事都不会被输入到审计表中。如果我注释掉RAISEERROR行，触发器会正确地将项目添加到审计表中，但当然数据将被删除。我在想我必须缺少一些简单的东西（如果我提出错误，会被删除不可用？），或者误解概念的某些元素。请告诉我我的方式的错误！ :)

编辑：亚伦伯特兰有正确的答案，我必须在提出错误之前提交我的审计数据。该RAISERROR基本卷回的一切，包括审计：

CREATE TRIGGER [dbo].[MyTable_prevent_delete_and_audit] 
ON [dbo].[MyTable] 
INSTEAD OF DELETE AS 
     BEGIN 
      DECLARE @SESSIONINFO nvarchar(200) 
      SELECT @SESSIONINFO = (RTRIM(LTRIM(CAST(login_time as nvarchar(20)))) + ' ' 
      + RTRIM(LTRIM(hostname)) + ' ' + RTRIM(LTRIM(program_name)) + ' ' 
      + RTRIM(LTRIM(cmd)) + ' ' + RTRIM(LTRIM(loginame))) from sys.sysprocesses WHERE spid = @@SPID 
      INSERT INTO [dbo].[MyTable_AUDIT] ([Field1],[Field1],[SESSIONINFO]) 
      SELECT [Field1],[Field1],@SESSIONINFO FROM deleted 
      COMMIT TRANSACTION; 
      RAISERROR ('Removing MyTable entries prevented by trigger. Contact your administrator', 16, 1) 
     END 
     RETURN 
GO

尝试提高错误之前提交的INSERT。否则，引发错误会回滚触发器所做的所有事情以及调用触发器的语句。

INSERT INTO [dbo].[MyTable_AUDIT] ([Field1],[Field1],[SESSIONINFO]) 
    SELECT [Field1],[Field1],@SESSIONINFO FROM deleted; 

COMMIT TRANSACTION; 

RAISERROR ('Removing MyTable entries prevented by trigger. ...', 16, 1);

这是它 - 我需要提高的错误之前提交数据。谢谢！ – cninsd
