EXECUTE后的事务计数表示BEGIN和COMMIT的数量不匹配？

Question

问：我有这样的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; 
BEGIN TRY 
    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 
     (
      ZO_BETE_UID 
      ,ZO_BETE_BE_ID 
      ,ZO_BETE_TE_UID 
      ,ZO_BETE_Sort 
      ,ZO_BETE_Status 
     ) 
     VALUES 
     (
      NEWID() --<ZO_BETE_UID, uniqueidentifier,> 
      ,@in_user --<ZO_BETE_BE_ID, int,> 
      ,@in_TE_UID --<ZO_BETE_TE_UID, uniqueidentifier,> 
      ,@in_ZO_BETE_Sort --<ZO_BETE_Sort, int,> 
      ,1 --<ZO_BETE_Status, int,> 
     ) 
     ; 
    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 
     (
      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 
      ) 
     ) 
     ; 

    END 

END TRY 
BEGIN CATCH 
    IF @@TRANCOUNT > 0 
     ROLLBACK TRANSACTION BeforeUpdate --RollBack in case of Error 

    --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 

，当我运行一次运行良好。

如果事后我跑

SELECT * FROM T_FMS_ZO_Benutzer_TeaserOrder 

然后超时。

如果我添加with (nolock)那么它的工作原理。

如果我看看SSMS中的进程，我看到一个锁定的选择与LCK_M_S。

如果我执行代码相同的命令，我总是得到这样的错误：

Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 0, current count = 1

所以真的，有什么不对的代码？

您还没有在您的SQL中的任何位置放入COMMIT。据推测，它应该只是END TRY

end    

Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 2, current count = 0. 

I AM FACING THIS SUCH TYPE PROBLEM................!!!!
