在SQL Server 2000

Question

我有SQL Server 2000問題引用三列到同一列的另一個表，我需要從數據庫的報告。我有一個名爲Automation的數據庫，它包含一組表來處理我們應用程序的票務處理查詢。

我需要提取從數據庫的報告應包含票號和用戶信息喜歡誰已經進入，接受，編輯，審查了票。

我需要這些字段從數據庫

Ticketnumber 
billnumber 
companyname 
enteredby(username) 
entereddate 
recievedby(username) 
recieveddate 
editedby(Employeename) 
editeddate 
reviewedby(ReviewerName) 
revieweddate 
postedby(Managername) 
posteddate 

我有三個表
1>VPP_VendorBilldetails

BillentryID | ticketnumber | billnumber | VENDORNAME,BILLNUMBER,COSTCENTERNAME,BILLAMOUNT,TICKETDATE,BILLDATE | companyID(not companyname) | billdate | Enteredby(userid)| entereddate | recievedby(userid) | recieveddate | editedby(userid) | editeddate | reviewedby(userid) | revieweddate | postedby(userid) | posteddate 

2>Users

UserID | employeeID | employeename |loginID| Password | usertype | status 

3>VPP_ClientCompanyDetails：

companyid | companyname | companyaddress | status 

我寫此查詢，但我對所有三個類別獲得相同的員工姓名：

SELECT CLIENTCOMPANYNAME, TICKETNUMBER,VENDORNAME,BILLNUMBER,COSTCENTERNAME,BILLAMOUNT,TICKETDATE,BILLDATE, 
    RECIEVEDDATE,EMPLOYEENAME AS EXECUTIVENAME, 
     VPP_VENDORBILLDETAILS.MODIFIEDDATE, 
     EMPLOYEENAME AS REVIEWERNAME,EMPLOYEENAME AS POSTEDBY,POSTEDDATE,ERRORCODE, 
     IMPACTCODE,ROOTCAUSE,REVIEWERREMARKS 
     FROM 
    VPP_VENDORBILLDETAILS 

    INNER JOIN 
    VPP_CLIENTCOMPANYDETAILS 
    ON VPP_VENDORBILLDETAILS.BILLENTEREDCOMPANYID = VPP_CLIENTCOMPANYDETAILS.CLIENTCOMPANYID 

    INNER JOIN USERS 
    ON VPP_VENDORBILLDETAILS.MODIFIEDBY = USERS.USERID 

    WHERE CONVERT(VARCHAR(12),CONVERT(DATETIME,POSTEDDATE,103),101) 
     BETWEEN CONVERT(DATETIME,CONVERT(VARCHAR(12),getdate()-7,100),101) 
     AND CONVERT(DATETIME,CONVERT(VARCHAR(12),getdate()-1,100),101) 

     AND VPP_CLIENTCOMPANYDETAILS.STATUS = 1 AND VPP_VENDORBILLDETAILS.STATUS = 1 AND USERS.STATUS = 1 AND ERRORCODE IS NOT NULL AND TALLYID IS NOT NULL 

     ORDER BY CLIENTCOMPANYNAME ASC 

請檢查並幫助我在此

試試這個：

SELECT CLIENTCOMPANYNAME, TICKETNUMBER,VENDORNAME,BILLNUMBER,COSTCENTERNAME,BILLAMOUNT,TICKETDATE,BILLDATE, 
    RECIEVEDDATE,U1.EMPLOYEENAME AS EXECUTIVENAME, 
     VPP_VENDORBILLDETAILS.MODIFIEDDATE, 
     U2.EMPLOYEENAME AS REVIEWERNAME,U3.EMPLOYEENAME AS POSTEDBY,POSTEDDATE,ERRORCODE, 
     IMPACTCODE,ROOTCAUSE,REVIEWERREMARKS 
     FROM 
    VPP_VENDORBILLDETAILS 

    INNER JOIN 
    VPP_CLIENTCOMPANYDETAILS 
    ON VPP_VENDORBILLDETAILS.BILLENTEREDCOMPANYID = VPP_CLIENTCOMPANYDETAILS.CLIENTCOMPANYID 

    INNER JOIN USERS U1 
    ON VPP_VENDORBILLDETAILS.recievedby = U1.USERID 

    INNER JOIN USERS U2 
    ON VPP_VENDORBILLDETAILS.MODIFIEDBY = U2.USERID 

    INNER JOIN USERS U3 
    ON VPP_VENDORBILLDETAILS.postedby = U3.USERID 


    WHERE CONVERT(VARCHAR(12),CONVERT(DATETIME,POSTEDDATE,103),101) 
     BETWEEN CONVERT(DATETIME,CONVERT(VARCHAR(12),getdate()-7,100),101) 
     AND CONVERT(DATETIME,CONVERT(VARCHAR(12),getdate()-1,100),101) 

     AND VPP_CLIENTCOMPANYDETAILS.STATUS = 1 AND VPP_VENDORBILLDETAILS.STATUS = 1 AND USERS.STATUS = 1 AND ERRORCODE IS NOT NULL AND TALLYID IS NOT NULL 

     ORDER BY CLIENTCOMPANYNAME ASC
