刪除數據OUT輸出的最後3個字符

Question

我有以下SQL查詢：

SELECT Sys.Name0, Sys.User_Name0, SF.FilePath, SF.Filename, Count(SF.FileName) AS FileCount, Sum(SF.FileSize/1024/1024) AS 'Used Space' 
FROM v_R_System Sys 
INNER JOIN v_GS_SoftwareFile SF ON Sys.ResourceID = SF.ResourceID 
WHERE SF.FilePath LIKE '%' + 'Users' + '%' + '%documents%' 
    AND SF.FileSize > 0 
GROUP BY Sys.Name0, Sys.User_Name0, SF.Filename, SF.FilePath 
HAVING Count(SF.FileName) > 0 
ORDER BY Sys.Name0 DESC 

的問題是，我得到了太多的信息。例如，我想排除記錄並不計算任何FILENAME就像.exe，.dll，.ico的地方。

Answer 1

如果你想排除，你可以將其添加到where子句中的記錄：

AND RIGHT(FileName,4) NOT IN('.exe', '.dll', '.ico', 'etc.') 

OR

AND Filename Not Like '%.exe' AND Filename Not Like '%.dll' AND Filename Not Like '%.ico' AND etc.... 

Answer 2

使用此Where子句（假設SQL Server）的

Where SF.FilePath like '%'+'Users'+'%' +'%documents%' 
and SF.FileSize > 0 
And FileName Not Like '%.exe' 
And FileName Not Like '%.dll' 
And FileName Not Like '%.ico' 

這應該讓你走....

Answer 3

您可以簡單地將它添加到where子句中作爲額外條件。爲排除文件名：

AND RIGHT(FileName,4) NOT IN('.exe', '.dll', '.ico', 'etc.') 

排除大於1mb的文件大小。

AND SF.FileSize > 1 

聲明全文：

SELECT 
    Sys.Name0, 
    Sys.User_Name0, 
    SF.FilePath, 
    SF.Filename, 
    Count(SF.FileName) AS FileCount, 
    Sum(SF.FileSize/1024/1024) AS 'Used Space' 
FROM 
    v_R_System Sys 
    INNER JOIN v_GS_SoftwareFile SF ON Sys.ResourceID = SF.ResourceID 
WHERE 
    SF.FilePath LIKE '%' + 'Users' + '%' + '%documents%' 
    AND SF.FileSize > 1 
    AND RIGHT(FileName,4) NOT IN('.exe', '.dll', '.ico', 'etc.') 
GROUP BY Sys.Name0, Sys.User_Name0, SF.Filename, SF.FilePath 
HAVING Count(SF.FileName) > 0 
ORDER BY Sys.Name0 DESC
