ALTER procedure [dbo].[email]
@DepID int
  as
    SELECT     
     dbo.DocumentInfo.DocName as DocumentName, 
     dbo.DocumentInfo.Uploadfile as FileUploaded, 
   dbo.Department.DepType as Department, 
  dbo.DocumentInfo.UploadedBy as UploadedBy, 
   dbo.ApproveType.ApproveType as Status
       FROM         dbo.DocumentInfo INNER JOIN
                  dbo.Approval ON dbo.DocumentInfo.DocID = dbo.Approval.DocID INNER
                         JOIN
                  dbo.ApproveType ON dbo.Approval.ApproveID =     
         dbo.ApproveType.ApproveID INNER JOIN
                  dbo.Userss on Userss.UserID =dbo.Userss.UserID inner join
                  dbo.Department ON dbo.DocumentInfo.DepID = dbo.Department.DepID
                  INNER JOIN
                  dbo.DocType ON dbo.DocumentInfo.DocTypeID = dbo.DocType.DocTypeID
                  where DocumentInfo.DepID=@DepID

这是用户表

 UserID  UserName Password UserTypeID  Email            DesgId 
   1     kety     cute         2       acv@ymail.com    4
   2     John     bravo        2       john@gmail.com   4

这是文档信息表

**DocId DocName       Uploadedfile DocTypeID DepID ApproveID UploadedBy UserID**
    18  hranaylsis    HR.docx        1         2    2         john         6
    19  ecoreport eco 2.docx         1         2    1         john         6

看来您正在尝试根据 UserName 加入表 - 我会做出这个假设。我还稍微清理了您的代码以使其更具可读性。看来您正在将 Userss 中的 UserId 字段加入到自身中。

 SELECT 
    di.DocName as DocumentName, 
    di.Uploadfile as FileUploaded, 
    d.DepType as Department, 
    di.UploadedBy as UploadedBy, 
    at.ApproveType as Status,
    u.Email as UserEmail
FROM dbo.DocumentInfo di 
       INNER JOIN dbo.Approval a 
       ON di.DocID = a.DocID 
       INNER JOIN dbo.ApproveType at
       ON a.ApproveID =  at.ApproveID 
       INNER JOIN dbo.Userss u
       ON u.UserId = di.UserId 
       INNER JOIN dbo.Department d 
       ON di.DepID = d.DepID
       INNER JOIN dbo.DocType  dct
       ON di.DocTypeID = dct.DocTypeID
where di.DepID= @DepID

您错误地加入了您的Userss表。

我已经清理了你的查询。您可以给每个表一个别名，而不是每次都写出整个表名，这使得查询看起来更容易阅读。

SELECT     
    di.DocName AS DocumentName, 
    di.Uploadfile AS FileUploaded, 
    di.UploadedBy AS UploadedBy, 
    d.DepType AS Department, 
    at.ApproveType AS Status,
    u.Email 
FROM dbo.DocumentInfo di
INNER JOIN dbo.Approval a ON di.DocID = a.DocID 
INNER JOIN dbo.ApproveType at ON a.ApproveID = at.ApproveID 
INNER JOIN dbo.Userss u ON di.UserID = u.UserID 
INNER JOIN dbo.Department d ON di.DepID = d.DepID
WHERE di.DepID = @DepID

这可能会立即起作用，否则请告诉我显示了什么错误。
