Question

我使用此查询在我的数据库中创建了一个函数：

CREATE FUNCTION dbo.fnSplit(
    @sInputList VARCHAR(MAX) -- List of delimited items
  , @sDelimiter VARCHAR(MAX) = ',' -- delimiter that separates items
) RETURNS @List TABLE (item VARCHAR(MAX))

BEGIN
DECLARE @sItem VARCHAR(MAX)
WHILE CHARINDEX(@sDelimiter,@sInputList,0) <> 0
 BEGIN
 SELECT
  @sItem=RTRIM(LTRIM(SUBSTRING(@sInputList,1,CHARINDEX(@sDelimiter,@sInputList,0)-1))),
  @sInputList=RTRIM(LTRIM(SUBSTRING(@sInputList,CHARINDEX(@sDelimiter,@sInputList,0)+LEN(@sDelimiter),LEN(@sInputList))))

 IF LEN(@sItem) > 0
  INSERT INTO @List SELECT @sItem
 END

IF LEN(@sInputList) > 0
 INSERT INTO @List SELECT @sInputList -- Put the last item in
RETURN
END
GO

SQL Server返回：Command(s) completed successfully.

然后我尝试运行此查询：

SELECT * FROM maj_Posts a
WHERE FeedID = (SELECT dbo.fnSplit(b.FeedIDs) FROM maj_Magazines b WHERE OwnerID = 1)
ORDER BY countOfComments DESC

它返回了一个错误：Msg 4121, Level 16, State 1, Line 1 Cannot find either column "dbo" or the user-defined function or aggregate "dbo.fnSplit", or the name is ambiguous.

请注意，b.FeedIDs是一个包含逗号分隔数字的字符串，如下所示：1,2,4

我想从maj_Posts获取行a.FeedID是b.FeedIDs中的数字之一... （例如，如果b.FeedIDs 1}}是1,2,4，我需要来自maj_Posts的行FeedID为1或2或4。）

有什么问题？

Answer 1

也许你的意思是：

SELECT * FROM maj_Posts a
LEFT OUTER JOIN dbo.maj_Magazines b
ON 1 = 1 AND b.OwnerID = 1
OUTER APPLY dbo.fnSplit(b.FeedIDs, ',') AS s
WHERE a.FeedID = s.item
ORDER BY countOfComments DESC;

或者

SELECT * FROM maj_Posts a
WHERE FeedID IN 
(
  SELECT item FROM maj_Magazines AS b
  CROSS APPLY dbo.fnSplit(b.FeedIDs, ',') 
  WHERE b.OwnerID = 1
)
ORDER BY countOfComments DESC;

SQL用户定义的函数，找不到dbo或用户自定义的函数
