Sql server 2008 需要有关SQL Server 2008中存储过程的帮助吗

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

我想要表1和表4的全部细节。我尝试了以下程序：

   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'

这里我得到n个rowa，即它每1个contentid返回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以归结为：

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

但我必须承认，我不确定DISTINCT在那里打算做什么。

我想你的问题有点不对劲-在你分配给

@ApprovalStatusID

的任务中，你真的打算纯粹基于

ContentID

搜索

开发内容版本

，然后根据

ContentID

和

SiteID

进行搜索？我注意到同一个语句使用了

@ContentID

——它只分配了一次，而不是在循环中递增的

@TEMP

。你能说这些是故意的吗？
