與計數查詢連接在SQL

Question

我嘗試創建一個SQL查詢計數，我試圖表明通知主管，經理，總監，當任何用戶上傳的在asp.net

查詢

ALTER procedure [dbo].[countdocuments] 
    @DepID int 
as 
    SELECT 
     COUNT(*), 
     Designation.DesigID 
    FROM DocumentInfo 
    INNER JOIN dbo.Userss ON dbo.Userss.DesigID = dbo.Designation.DesigID 
    WHERE 
     Userss.DesigID = 'Finance' 

新文件

但是當我執行它，以下錯誤發生

消息4104，級別16，狀態1，過程countdocuments，行7
多部分標識符「dbo.Design ation.DesigID「不能被綁定。
Msg 4104，Level 16，State 1，Procedure countdocuments，Line 5
無法綁定多部分標識符「Designation.DesigID」。

確定這是我designation表

DesigID DesigType 
    1  SuperVisor 
    2  Manager 
    3  Director 
    4  BasicUsers 

，這是documentinfo表

DocID DocDescrit DocName UploadedDate Uploadfile DocTypeID DepID ApproveID UploadedBy UserID 
32 asp.net codescomputer 2013-12-30 22:30:00.623 details.docx 1 2 1amna 24 

，這是userss表

UserID UserName Password UserTypeID DepID CreateDate Email PhoeNumber DesigID 
21 john abc 2 NULL NULL 2013-12-02 22:01:03.903 NULL abc@hotmail.com 12313 4 

，當我嘗試這個闕RY

ALTER procedure [dbo].[countdocuments] 
    @DepID int 
as 
BEGIN 
    SET NOCOUNT ON; 

    SELECT 
     COUNT(*) AS Cnt, Designation.DesigID 
    FROM 
     Designation 
    INNER JOIN 
     dbo.Userss ON dbo.Userss.DesigID = dbo.Designation.DesigID 
    WHERE 
     Userss.DesigID = @DepID 
    GROUP BY 
     Designation.DesigID 
END 

當我嘗試用@depid = 4執行這樣的表現我這個樣子，我不明白的地方是4從哪裏來..

Cnt DesigID 
4  4 

Answer 1

ALTER procedure [dbo].[countdocuments] 
@DepID int 
as 
BEGIN 
    SET NOCOUNT ON; 
    SELECT COUNT(*) AS Cnt,Designation.DesigID 
    FROM DocumentInfo inner join dbo.Userss 
    on dbo.Userss.DesigID = dbo.DocumentInfo.DesigID 
    WHERE Userss.DesigID = @DepID 
    GROUP BY DocumentInfo.DesigID 

END 

您在不同的表名你的JOIN條款和ON條款。我試圖修復它，假設您的DocumentInfo表中有DesigID列。在您的評論

尋找嘗試以下

ALTER procedure [dbo].[countdocuments] 
@DepID int 
as 
BEGIN 
SET NOCOUNT ON; 
SELECT COUNT(*) AS Cnt,Designation.DesigID 
FROM Designation left join dbo.Userss 
on dbo.Userss.DesigID = dbo.Designation.DesigID 
left Join DocumentInfo on Userss.UserId= DocumentInfo.UserId and Designation.DepId = DocumentInfo.DepId 
WHERE Userss.DesigID = @DepID 
GROUP BY Designation.DesigID 

END 

或者試試下面

Looking at your comment try following 

ALTER procedure [dbo].[countdocuments] 
@DepID int 
as 
BEGIN 
SET NOCOUNT ON; 
SELECT COUNT(*) AS Cnt,Designation.DesigID 
FROM DocumentInfo left Join Userss on DocumentInfo.UserId = Userss.UserId 
left Join Designation on DocumentInfo.DepId = Designation.DeptId 
and Designation.DesigID = Userss.DesigId 
WHERE Userss.DesigID = @DepID 
GROUP BY Designation.DesigID 

END
