Question

我有4张桌子：

表1

ContentID(pk)
ContentGUID
Description
SiteID
CategoryID
StartDate
DisplayName
ParentId
AssignedAuthors
AssignedEditors
CreatedBy
U.UserName
Created
ModifiedBy
UserName
Modified
Priority

表2

ContentID(fk)
versionid(pk)
page

表3

apprhistroyid(pk)
verstionid(fk)
approvalstatusid(fk)

表4

approvalstatusid(pk)
statusname

我想要table1和table4的全部细节。我尝试过以下程序：

   ALTER PROCEDURE [dbo].[DEV_SiteAdmin_Menu_GetItem_ALL_TEMP] 
@SiteID Int

   AS
DECLARE @VersionID int, @ApprovalStatusID int,@StatusName nvarchar(max),@ContentID Int,@Rowcount int
DECLARE @TEMP INT

--set @ApprovalStatusID=5;
--set @StatusName ='New';
set @Rowcount=(select max(ContentID)from dev_content where SiteID=@SiteID)
set @ContentID=(select min(ContentID) from dev_content where SiteID=@SiteID)
SET @TEMP=@ContentID
IF(@Rowcount>=1) 

    BEGIN
        WHILE @Rowcount>1
        BEGIN
            SET @Rowcount=@Rowcount-1
            set @ApprovalStatusID= 
CASE 
WHEN exists (SELECT VersionID from DEV_ContentVersion WHERE ContentID=@TEMP)
THEN (SELECT ApprovalStatusID FROM DEV_ApprovalStatus WHERE ApprovalStatusID=(SELECT ApprovalStatusID FROM DEV_ApprovalHistory WHERE VersionID=(SELECT VersionID from DEV_ContentVersion WHERE ContentID=(select ContentID from dev_content where ContentID=@ContentID and SiteID=@SiteID)))) else 5   end
set @StatusName=
case
when (@ApprovalStatusID != 5)
then 
(SELECT StatusName FROM DEV_ApprovalStatus WHERE ApprovalStatusID=@ApprovalStatusID) 
else
'New'
end
        SELECT DISTINCT [ContentID]
                  ,[ContentGUID]
                  ,[Description]
                  ,[SiteID]
                  ,[CategoryID]
                  ,[StartDate]
                  ,[DisplayName]
                  ,[ParentId]
                  ,[AssignedAuthors]
                  ,[AssignedEditors]
                  ,[CreatedBy]
                  ,U.UserName 'CreatedUser'
                  ,dbo.fnGetUserNamesFromUserIds([AssignedAuthors],',') 'Authors'
                  ,dbo.fnGetUserNamesFromUserIds([AssignedEditors],',') 'Editors'
                  ,[Created]
                  ,[ModifiedBy]
                  ,U1.UserName 'ModifiedUser'
                  ,[Modified]
                  ,[Priority]
                  ,@ApprovalStatusID [ApprovalStatusID]
                  ,@StatusName [StatusName]
              FROM [DEV_Content] C
              INNER JOIN dbo.aspnet_Users U ON U.UserId=C.CreatedBy
              INNER JOIN dbo.aspnet_Users U1 ON U1.UserId=C.ModifiedBy
              WHERE C.SiteID=@SiteID AND [ContentID] = @TEMP
              SET @TEMP= @TEMP+1
         END
     END
     else
     print 'error'

我得到的是rowa的n号，它返回每1个有争议的1行，而我希望所有返回值都作为一个表。

我认为您的整个查询可归结为：

SELECT 
    [ContentID]
    ,[ContentGUID]
    ,[Description]
    ,[SiteID]
    ,[CategoryID]
    ,[StartDate]
    ,[DisplayName]
    ,[ParentId]
    ,[AssignedAuthors]
    ,[AssignedEditors]
    ,[CreatedBy]
    ,U.UserName as CreatedUser
    ,dbo.fnGetUserNamesFromUserIds([AssignedAuthors],',') as Authors
    ,dbo.fnGetUserNamesFromUserIds([AssignedEditors],',') as Editors
    ,[Created]
    ,[ModifiedBy]
    ,U1.UserName as ModifiedUser
    ,[Modified]
    ,[Priority]
    ,COALESCE(ah.ApprovalStatusID,5) as ApprovalStatusID
    ,COALESCE(ast.StatusName,'New' as StatusName
FROM
    [DEV_Content] C
        INNER JOIN
    dbo.aspnet_Users U
        ON
            U.UserId=C.CreatedBy
        INNER JOIN
    dbo.aspnet_Users U1
        ON
            U1.UserId=C.ModifiedBy
        left join
    DEV_ContentVersion cv
        inner join
    DEV_ApprovalHistory ah
        on
            cv.VersionID = ah.VersionID
        inner join
    DEV_ApprovalStatus ast
        on
            ah.ApprovalStatusID = ast.ApprovalStatusID
        on
            C.ContentID = cv.ContentID

WHERE
    C.SiteID=@SiteID

但我不得不承认，我不确定DISTINCT在那里的意图是什么。

需要有关SQL Server 2008中的存储过程的帮助
