存儲過程中的obj名稱無效

Question

我有一個存儲過程，我正在使用交叉應用從表中獲取一個字段「tagtext」，然後將每個tagtext作爲一個條目放在名爲另一個表中的標記的新字段中。我不想熱衷於如何交叉應用作品，但似乎得到一個錯誤：無效的對象myArticles。

從我的SP相關的代碼是：

BEGIN 
    -- SET NOCOUNT ON added to prevent extra result sets from 
    -- interfering with SELECT statements. 
    SET NOCOUNT ON; 

    -- Insert statements for procedure here 
    declare @RowStart int 
    declare @RowEnd int 
    IF (@Page=1) 
     Begin 

      set @RowStart=(@Page-1)*(@PageLen) 
      set @RowEnd=(@RowStart+@PageLen); 
     END 
    ELSE 
     BEGIN 

      set @RowStart=((@Page-1)*(@PageLen))+1 
      set @RowEnd=((@RowStart+@PageLen))-1 
     END; 
     With myArticles as 
(select ROW_NUMBER() over (ORDER BY publicationdate DESC) as 'RowNumber',* 

From article_v 
where articleID in(select articleID from savedarticle where userID= @UserID) and 
title like '%'+@keyword1+'%' and 
title like '%'+@keyword2+'%' and 
title like '%'+@keyword3+'%' and 
title like '%'+@keyword4+'%' and 
title like '%'+@keyword5+'%' 
) 

(select mA.*, 
isnull(left(Tags,len(Tags)-1),'') as Tags 
from myArticles mA 
    cross apply (select tagtext +', ' 
    from usertag uTag 
    where uTag.userID=@userID and uTag.usertagID in(select usertagID from articletag aTag where aTag.articleID=mA.articleID) 
    for xml path('')) ca(Tags) 
) 
     select 
      rownumber,journalID,journalname,articleID,title,publicationdate,medabbr, authors, Tags 
      from myArticles where RowNumber Between @RowStart and @RowEnd 
END 


GO 

然後，我使用的SP在Web服務：

<WebMethod()> _ 
Public Function GetSavedArticlesWithAbbr(ByVal mobileGUID As String, ByVal pageNum As Integer, ByVal pageLen As Integer, ByVal keywords As String) As List(Of ipadArticle) 
    Dim result As New List(Of ipadArticle) 
    keywords = HttpUtility.UrlDecode(keywords) 
    Dim tempParamKW() As String = {"", "", "", "", ""} 
    Dim tempKW() As String = keywords.Split(" ") 
    Dim tempILoop As Integer = 0 
    For Each s As String In tempKW 
     tempParamKW(tempILoop) = s.Trim 
     tempILoop += 1 
    Next 
    Dim simpuser As SimpleUser = utils.GetSimpleUserInfoFromMobileGUID(mobileGUID) 
    If simpuser.isValid Then 
     Dim lq As New lqDFDataContext 
     Dim var = lq.mobile_GetSavedArticlesJW(simpuser.UserID, tempParamKW(0), tempParamKW(1), tempParamKW(2), tempParamKW(3), tempParamKW(4), pageNum, pageLen) 
     For Each a_var In var 
      Dim ipadartcicle As New ipadArticle() 
      ipadartcicle.ArticleID = a_var.articleID 
      ipadartcicle.PublishedOn = a_var.publicationdate 
      ipadartcicle.Title = a_var.title 
      ipadartcicle.MedAbbr = a_var.medabbr.Replace(" ", "-").ToLower() 

      Dim tempTags() As String = a_var.Tags.Split(",") 
      For Each t As String In tempTags 
      ipadartcicle.Tags.Add(t) 
      Next 

      Dim tempAuthors() As String = a_var.Authors.Split(",") 
      For Each a As String In tempAuthors 
      ipadartcicle.Authors.Add(a) 
      Next 

      result.Add(ipadartcicle) 
     Next  'this is where i get the error 
    End If 
    Return result 
End Function 

Answer 1

我會說，你想鏈中的另一個CTE在下面的代碼中的右括號和右括號之間，但忘了它：

title like '%'+@keyword5+'%' 
) 

(select mA.*, 

這應該可能是

title like '%'+@keyword5+'%' 
), 
myArticles2 as (select mA.*, 

然後查詢的最後部分應該使用myArticles2。正如現在寫的，最後的選擇不是cte查詢的一部分。

Answer 2

試試這個，這就像你錯過了第二部分

With myArticles as 
(select ROW_NUMBER() over (ORDER BY publicationdate DESC) as 'RowNumber',* 

From article_v 
---rest of query here 
), 
myArticles2 as 
(
select mA.*, 
isnull(left(Tags,len(Tags)-1),'') as Tags 
from myArticles mA 
    cross apply (select tagtext +', ' 
    --- rest of query here 
) 
    select 
      rownumber,journalID,journalname, .... rest of query here
