Question

具有下面的mssql存储过程。我想根据结果insdie sp返回值0或1并从sp返回。在我的示例中，当我调试它并到达它时（我在查询中用第二个箭头标记）注释点不会到达SELECT 0 / RETURN 0行，但是在窗口中我可以看到“无列名” 0-意味着符合预期，但当我使用其他输入值进行调试时，当到达（第一个箭头）注释时，它也不会转到SELECT 1 / RETURN 1，并且没有像我期望的那样出现“ No column name” 1之类的消息。为什么在调试器中，它在到达SELECT/RETURN statemts之前中断了注释的存储过程，以及为什么SELECT 1 / RETURN 1没有结果。我在做什么错了？

致@Sean Lange：

请注意，当@SubsubkatId的输入值为NULL时，如在我的sp中一样，必须使用此查询：

INSERT INTO @temp_T_Html_Word_Categories(Id) SELECT Id FROM T_Html_Word_Categories WHERE FK_KatSubkat_ID = @KatSubkatId And FK_Word_ID = @WordId;

当有somethnig（不为null）时，则必须使用这些查询（也在我的sp中）：

INSERT INTO @temp_T_Html_Word_Categories(Id) SELECT Id FROM T_Html_Word_Categories WHERE FK_KatSubkat_ID = @KatSubkatId And FK_Word_ID = @WordId And FK_Subsubkat_ID = @SubsubkatId;
            INSERT INTO @temp_T_Html_Word_Categories(Id) SELECT Id FROM T_Html_Word_Categories WHERE FK_KatSubkat_ID = @KatSubkatId And FK_Word_ID = @WordId And FK_Subsubkat_ID IS NULL;

我不确定您的简化版本是否与之匹配。

不太确定想要什么，但是可以确定可以将ENTIRE过程简化为这样的单个语句。绝对不需要循环并使之变得如此复杂。

ALTER PROCEDURE [dbo].[IsPhraseConnectedAlready]
    @PhraseId INT,
    @KatSubkatId INT,   
    @WordId INT,
    @SubsubkatId INT = NULL
AS
BEGIN
    SET NOCOUNT OFF;

    select DoesItExist = convert(bit, count(*)) 
    from T_Html_Word_Categories c
    join T_Html_WordCat_Phrase wcp pm wcp.FK_Word_Categorie_ID = c.ID AND FK_Phrase_ID=@PhraseId
    WHERE c.FK_KatSubkat_ID = @KatSubkatId 
        And c.FK_Word_ID = @WordId
        And c.FK_Subsubkat_ID = isnull(@SubsubkatId, c.FK_Subsubkat_ID)

END

通过选择返回值返回
