SQLServer 异常捕获，回滚，再抛出

一个存储过程中多个更新操作，后面的更新操作出现异常，如果不手动回滚前面修改的数据是不会自动撤销的！

BEGIN TRY

    BEGIN TRAN

-- .....

    COMMIT TRAN

END TRY



BEGIN CATCH

    ROLLBACK TRAN



    DECLARE @ErrorMessag NVARCHAR(255)

    SELECT @ErrorMessag = Error_message()

    RAISERROR (15600,-1,-1,@ErrorMessag);

END CATCH
