如何在SQL Server抛出中创建连锁消息？

Question

我有这个代码:

IF (@CurrentResult != 'N' AND @CurrentResult != 'F')
    THROW 50002, 'Question should be unmarked or incorrect', 1

有人可以向我解释我如何在我抛出的错误消息中给出@CurrentResult吗？

我想要的是消息显示如下:

Question result is 'X'. It should be unmarked or incorrect?

其中X是@CurrentResult的值.

您不能在THROW语句中连接字符串.

您需要做的是创建一个变量并将整个错误消息分配给它:

DECLARE @Messssage NVARCHAR(100)
SET @Message = N'Question result is ''' + @CurentResult + '''. It should be unmarked or incorrect?'

IF (@CurrentResult != 'N' AND @CurrentResult != 'F')
    THROW 50002,@Message,1
