Question

当只有导演批准/拒绝文件或待处理时，我想向用户显示此文件是批准/拒绝..

这是我尝试的存储过程

ALTER procedure [dbo].[spdocuments]
as
   SELECT    
      dbo.DocumentInfo.DocName as DocumentName,
      dbo.DocumentInfo.UploadedDate as UploadedDate , 
      dbo.DocumentInfo.Uploadfile as FileUploaded,   
      dbo.DocumentInfo.UploadedBy as  UploadedBy,
      dbo.Department.DepType as Department,
      dbo.Approval.ApproveDate,
      dbo.Approval.AppoveBy,
      dbo.ApproveType.ApproveType as Status
   FROM         
      dbo.DocumentInfo
   INNER JOIN
      dbo.Department ON dbo.DocumentInfo.DepID = dbo.Department.DepID 
   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.ApproveType AS ApproveType_1 ON dbo.Approval.ApproveID = ApproveType_1.ApproveID
   WHERE      
      (dbo.Approval.DesigID = 3)

当我执行它时，它会向我显示这样的结果

在上面的表中重复两次或多次，我希望记录在单个时间表中每个记录都是单次

Answer 1

在您的原始问题（编辑之前）中，您说您希望所有“已批准”，然后所有“待定”（未批准）。您还提到一些Approved比其他一些更重要，但我无法从数据或您的描述中确定哪些。但是，此查询显示如何获取已批准（每个文档只有一行），然后是任何待定（尚未批准）。

顺便说一下，这也可以使用一些连接语句而不是联合来完成，但有时这种格式更容易调试（因为你可以注释掉一个联合集或对其进行处理）分开）。

--Approved
SELECT
  dbo.DocumentInfo.DocName as DocumentName,
  dbo.DocumentInfo.UploadedDate as UploadedDate , 
  dbo.DocumentInfo.Uploadfile as FileUploaded,   
  dbo.DocumentInfo.UploadedBy as  UploadedBy,
  dbo.Department.DepType as Department,
  Max(dbo.Approval.ApproveDate) AS ApproveDate,
  Max(dbo.Approval.AppoveBy) AS ApproveBy,
  dbo.ApproveType.ApproveType as Status
FROM         
  dbo.DocumentInfo
INNER JOIN
  dbo.Department ON dbo.DocumentInfo.DepID = dbo.Department.DepID 
INNER JOIN
  dbo.Approval ON dbo.DocumentInfo.DocID = dbo.Approval.DocID 
INNER JOIN
  dbo.ApproveType ON dbo.Approval.ApproveID = dbo.ApproveType.ApproveID 
GROUP BY 
  dbo.DocumentInfo.DocName as DocumentName,
  dbo.DocumentInfo.UploadedDate as UploadedDate, 
  dbo.DocumentInfo.Uploadfile as FileUploaded,   
  dbo.DocumentInfo.UploadedBy as  UploadedBy,
  dbo.Department.DepType as Department
WHERE      
  (dbo.Approval.DesigID = 3)
AND dbo.ApproveType.ApproveType = 'Approve'

UNION

--Pending
SELECT
  dbo.DocumentInfo.DocName as DocumentName,
  dbo.DocumentInfo.UploadedDate as UploadedDate , 
  dbo.DocumentInfo.Uploadfile as FileUploaded,   
  dbo.DocumentInfo.UploadedBy as  UploadedBy,
  dbo.Department.DepType as Department,
  Max(dbo.Approval.ApproveDate) AS ApproveDate,
  Max(dbo.Approval.AppoveBy) AS ApproveBy,
  dbo.ApproveType.ApproveType as Status
FROM         
  dbo.DocumentInfo
INNER JOIN
  dbo.Department ON dbo.DocumentInfo.DepID = dbo.Department.DepID 
INNER JOIN
  dbo.Approval ON dbo.DocumentInfo.DocID = dbo.Approval.DocID 
INNER JOIN
  dbo.ApproveType ON dbo.Approval.ApproveID = dbo.ApproveType.ApproveID 
GROUP BY 
  dbo.DocumentInfo.DocName as DocumentName,
  dbo.DocumentInfo.UploadedDate as UploadedDate, 
  dbo.DocumentInfo.Uploadfile as FileUploaded,   
  dbo.DocumentInfo.UploadedBy as  UploadedBy,
  dbo.Department.DepType as Department
WHERE      
  (dbo.Approval.DesigID = 3)
AND dbo.ApproveType.ApproveType = 'Pending'
AND dbo.DocumentInfo.DocID NOT IN
( 
  --omit the pending that have been approved
  SELECT
    dbo.DocumentInfo.DocID
  FROM         
    dbo.DocumentInfo
  INNER JOIN
    dbo.Department ON dbo.DocumentInfo.DepID = dbo.Department.DepID 
  INNER JOIN
    dbo.Approval ON dbo.DocumentInfo.DocID = dbo.Approval.DocID 
  INNER JOIN
    dbo.ApproveType ON dbo.Approval.ApproveID = dbo.ApproveType.ApproveID 
  GROUP BY 
    dbo.DocumentInfo.DocID as DocumentName,
    dbo.Department.DepType as Department
  WHERE      
    (dbo.Approval.DesigID = 3)
  AND dbo.ApproveType.ApproveType = 'Approved'
)

按指定显示文件
