Question

我尝试使用此存储过程来显示文档：

ALTER procedure [dbo].[financespmanager] 
     @DepID int
as
    SELECT     
        dbo.DocumentInfo.DocID as DocumentID, 
        dbo.DocumentInfo.DocName as DocumentName, 
        dbo.DocumentInfo.Uploadfile as FileUploaded, 
        dbo.Department.DepType as Department, 
        dbo.DocType.DocType as Document,
        dbo.DocumentInfo.UploadedBy as UploadedBy, 
        dbo.Approval.AppoveBy, 
        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.Department ON dbo.DocumentInfo.DepID = dbo.Department.DepID
    INNER JOIN
        dbo.DocType ON dbo.DocumentInfo.DocTypeID = dbo.DocType.DocTypeID
    WHERE     
        DocumentInfo.DepID = @DepID

现在，当我测试查询时，它会像我一样显示

DocumentID  DocumentName  FileUploaded    Departmen   UploadedBy   AppoveBy    Status
 25       css           dsfsdf.docx     Computer    edward       halten      Rejected
 18       hr            HR.docx         Computer    john         halten      Approved
 19       eco           eco 2.docx      Computer    kety         halten      Rejected
 24       plan          December8.pdf   Computer    edward       halten      Approved

现在，我想在此处仅显示已批准的文件，而不是拒绝和待处理的文件

我该怎么做？

Answer 1

您的WHERE子句中只需要一个附加条件：

WHERE     
    DocumentInfo.DepID = @DepID 
    AND dbo.ApproveType.ApproveType = 'Approved'

应该这样做。

Answer 2

尝试...

AND ApproveType.ApproveType = 'Approved'在where子句中。

或者，更改存储过程以获取第二个参数 ...

ALTER procedure [dbo].[financespmanager] 
     @DepID int,
     @Status varchar(30) = 'Approved'
as
--rest of sp
WHERE 
DocumentInfo.DepID = @DepID 
AND ApproveType.ApproveType = @Status

默认值为Approved，但您也可以传入另一个值来覆盖...

EXEC [dbo].[financespmanager] @DepID = n, @Status = 'Rejected'

这将允许您“按原样”使用SP，但也可以灵活地覆盖。

只应显示已批准的文件
