Question

问题：我有这个SQL脚本：

DECLARE @in_TE_UID varchar(36) 
DECLARE @in_ZO_BETE_Sort int 
DECLARE @in_user int 


SET @in_TE_UID = '9f510440-8828-44ce-bbea-6bc866902262'
SET @in_ZO_BETE_Sort = 0 
SET @in_user = 12435

BEGIN TRANSACTION BeforeUpdate;

    IF NOT EXISTS 
    (
        SELECT 1 FROM T_FMS_ZO_Benutzer_TeaserOrder 
        WHERE (T_FMS_ZO_Benutzer_TeaserOrder.ZO_BETE_Status = 1) 
        AND (T_FMS_ZO_Benutzer_TeaserOrder.ZO_BETE_BE_ID = @in_user) 
        AND 
        (
            T_FMS_ZO_Benutzer_TeaserOrder.ZO_BETE_TE_UID = @in_TE_UID 
            OR 
            (
                @in_TE_UID IS NULL 
                AND 
                T_FMS_ZO_Benutzer_TeaserOrder.ZO_BETE_TE_UID IS NULL 
            ) 
        )    
    )
    BEGIN
        INSERT INTO T_FMS_ZO_Benutzer_TeaserOrder 
        (

        ;
    END
    ELSE
    BEGIN

        UPDATE T_FMS_ZO_Benutzer_TeaserOrder  
            SET  ZO_BETE_Sort = @in_ZO_BETE_Sort 

        WHERE (T_FMS_ZO_Benutzer_TeaserOrder.ZO_BETE_Status = 1) 
        AND (T_FMS_ZO_Benutzer_TeaserOrder.ZO_BETE_BE_ID = @in_user) 
        AND 
        (

        ) 
        ;

    END

END TRY
BEGIN CATCH

    --RETURN


    DECLARE @ErrorMessage NVARCHAR(4000);
    DECLARE @ErrorSeverity INT;
    DECLARE @ErrorState INT;

    SELECT 
        @ErrorMessage = ERROR_MESSAGE(),
        @ErrorSeverity = ERROR_SEVERITY(),
        @ErrorState = ERROR_STATE();

    -- Use RAISERROR inside the CATCH block to return error
    -- information about the original error that caused
    -- execution to jump to the CATCH block.
    RAISERROR (@ErrorMessage, -- Message text.
               @ErrorSeverity, -- Severity.
               @ErrorState -- State.
    );
END CATCH

当我运行一次时运行正常。

如果之后我跑了

SELECT * FROM T_FMS_ZO_Benutzer_TeaserOrder

然后超时。

如果我添加with (nolock)，那就可以了。

如果我查看SSMS中的进程，我会看到LCK_M_S的锁定选择。

如果我在代码中执行相同的命令，我总是会收到此错误：

EXECUTE之后的事务计数表示BEGIN和COMMIT语句的数量不匹配。先前的计数= 0，当前计数= 1

真的，这段代码出了什么问题？

Answer 1

您还没有在任何地方放置COMMIT。据推测它应该在END TRY

之前

EXECUTE后的事务计数表示BEGIN和COMMIT的数量不匹配？
