这就是我的解决方案:

...

BEGIN
    raiserror('Invalid database', 15, 10)
    rollback transaction
    return
END

将适当的代码块包装在try catch块中。然后，如果您愿意，可以使用严重程度为11的Raiserror事件，以便中断到catch块。如果你只想抛出错误，但在try块内继续执行，那么使用较低的严重程度。

试一试……抓住(transact - sql)

谢谢你的回答!

Raiserror()工作得很好，但你不应该忘记return语句，否则脚本将继续没有错误!(因此，raiserror不是一个“throwerror”;-))，当然，如果需要，还会进行回滚!

Raiserror()用于告诉执行脚本的人出错了。

这些都不能用于“GO”语句。在这段代码中，无论严重程度是10还是11，都将得到最终的PRINT语句。

测试脚本:

-- =================================
PRINT 'Start Test 1 - RAISERROR'

IF 1 = 1 BEGIN
    RAISERROR('Error 1, level 11', 11, 1)
    RETURN
END

IF 1 = 1 BEGIN
    RAISERROR('Error 2, level 11', 11, 1)
    RETURN
END
GO

PRINT 'Test 1 - After GO'
GO

-- =================================
PRINT 'Start Test 2 - Try/Catch'

BEGIN TRY
    SELECT (1 / 0) AS CauseError
END TRY
BEGIN CATCH
    SELECT ERROR_MESSAGE() AS ErrorMessage
    RAISERROR('Error in TRY, level 11', 11, 1)
    RETURN
END CATCH
GO

PRINT 'Test 2 - After GO'
GO

结果:

Start Test 1 - RAISERROR
Msg 50000, Level 11, State 1, Line 5
Error 1, level 11
Test 1 - After GO
Start Test 2 - Try/Catch
 CauseError
-----------

Divide by zero error encountered.

Msg 50000, Level 11, State 1, Line 10
Error in TRY, level 11
Test 2 - After GO

实现这一功能的唯一方法是编写没有GO语句的脚本。有时候这很简单。有时候真的很困难。(使用IF @error <> 0 BEGIN ....)

你可以使用GOTO语句改变执行流程:

IF @ValidationResult = 0
BEGIN
    PRINT 'Validation fault.'
    GOTO EndScript
END

/* our code */

EndScript:

在过去，我们使用了以下语句:效果最好:

RAISERROR ('Error! Connection dead', 20, 127) WITH LOG
