我设计了一个脚本，该脚本会将日志文件数据上传到oracle数据库。但是我想在数据上传中过滤图像。在这种情况下，我不希望我的代码上传请求中具有.gif扩展名的CLIENT_REQUEST（“ GET /icons/back.gif HTTP / 1.1”）。有人可以帮助我进行查询。

我的日志文件

127.0.0.1,-,-,[06/Aug/2018:09:22:02 +0200],"GET /icons/back.gif HTTP/1.1",304,-,"-"
127.0.0.1,-,-,[06/Aug/2018:09:22:02 +0200],"GET /icons/blank.gif HTTP/1.1",304,-,"-"
127.0.0.1,-,-,[06/Aug/2018:09:22:02 +0200],"GET /icons/unknown.gif HTTP/1.1",304,-,"-"
127.0.0.1,-,-,[06/Aug/2018:09:22:02 +0200],"GET /icons/image2.gif HTTP/1.1",304,-,"-"
127.0.0.1,-,-,[06/Aug/2018:09:22:02 +0200],"GET /icons/text.gif HTTP/1.1",304,-,"-"

如果将日志文件用作外部表，则可以通过（PL /）SQL load 加载它，并实际编写一个http.createServer(function(request, response) { try{ response.writeContinue(undefinedVariable); }catch (error) { response.status(400).end(error.message); } }).listen(port);子句来拒绝此类行。例如：

WHERE

有什么办法可以丢弃Oracle数据库中的图像文件？
