次のクエリを使用して、データベースに関数を作成しました。

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

そして、SQL Server は以下を返しました:Command(s) completed successfully.

次に、このクエリを実行しようとしました：

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

エラーが返されました：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.

b.FeedIDs文字列には、次のようにカンマ区切りの数字が含まれていることに注意してください。1,2,4

maj_Postsそして、theirが...a.FeedIDの数字の 1 つである行を取得したいb.FeedIDs(たとえば、b.FeedIDsisの場合、theirが 1 または 2 または 4で1,2,4ある行が必要です。)maj_PostsFeedID

何が問題ですか？

おそらくあなたはこれを意味しました：

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;

または

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;
