Question

我有以下SQL查询：

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

问题是，我得到的信息太多了。我想排除记录而不计算FILENAME就像.exe，.dll，.ico这样的地方。

Answer 1

如果您希望排除记录，可以将其添加到where子句：

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（假设SQL Server）

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'

这应该让你去....

Answer 3

您可以将其添加到where子句作为额外条件。排除文件名：

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

排除大于1mb的文件大小。

AND SF.FileSize > 1

完整陈述：

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

从输出最后3个字符中删除数据
