Sql server 通过选择return返回值

有下面的mssql存储过程。我想根据sp中的结果检索值0或1，并从sp返回。在我的示例中，当我调试它时，当它达到我在查询中用第二个箭头注释点标记的值时，它不会转到选择0/返回0行，但在窗口中，我看不到任何列名0-表示似乎与预期一样好，但当我使用其他输入值进行调试时当它到达第一个箭头注释时，它也不会像我预期的那样选择1/返回1，并且不会像没有列名1那样显示任何消息。为什么在调试器中，它会在到达SELECT/RETURN statemts之前中断注释上的存储过程，为什么SELECT 1/RETURN 1没有结果。我做错了什么

如果存在不为null的某些查询，则这些查询也必须在我的sp中使用：

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。

我不确定您想要什么，但我非常确定您可以将整个过程简化为这样一条语句。绝对没有必要循环并使其如此复杂

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

为什么在这里使用循环？这只不过是对EXISTS进行一次查询，或者可能与join一样简单，但要通过最复杂的路径到达那里。@SeanLange，因为可能有多个结果，并且必须循环到每个结果中。首先，它将找到需要返回值并停止sp的内容。但您只是在检查是否存在……在这里循环是一种非常缓慢的方法。@SeanLange然后您能提出解决方案吗？尽管如此，我还是想理解它为什么会这样。代码比您认为的要快的原因是IF语句没有begin/end。同样地，IF语句将只执行下一行。

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
