| How long does it usually take to execute such query? I’m quite sure that you’re facing with an I/O timeout that terminates the connection between the client and server because query execution takes long time on the server side.
Yeah, I have the same guess. So what I should to do ? Increase timeout or try new version ? When it comes to increase timeout - is it possible to do it using xml config file? 2016-05-26 15:53 GMT+02:00 Denis Magda <[email protected]>: > Hi, > > How long does it usually take to execute such query?
