SQL用户定义函数，找不到dbo或用户定义函数

I have created a function in my database using this query:

我已经在我的数据库中使用这个查询创建了一个函数:

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

And SQL Server returned : Command(s) completed successfully.

SQL Server返回:命令成功完成。

Then I tried to run this query:

然后我尝试运行这个查询:

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

It returned an error: 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.

它返回了一个错误:msg4121，级别16，状态1，第1行无法找到“dbo”列或用户定义函数或聚合“dbo”。fnSplit"，或名称不明确。

Note that b.FeedIDs is an string contains comma-separated numbers, like this : 1,2,4

请注意,b。FeedIDs是一个包含逗号分隔数的字符串，例如:1、2、4。

And I want to get rows from maj_Posts which their a.FeedID is one of the numbers in b.FeedIDs... (For example, if b.FeedIDs is 1,2,4, I need rows from maj_Posts that their FeedID is 1 or 2 or 4.)

我想从maj_Posts中获取行。菲迪德是b.FeedIDs…(例如,如果b。FeedIDs是1、2、4，我需要来自maj_Posts的行，它们的衰弱是1、2或4)。

What is the problem?

这个问题是什么?

2 个解决方案

#1

Perhaps you meant this:

也许你是这样的:

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;

Or

或

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;
