title: Error: Cannot enqueue Query after fatal error in mysql node
body: <p>I am using felixge/node-mysql. Also I am using express-myconnection which prevents mysql timeout and in turn prevents killing of node server. What I am doing is logging the activities in mysql. The scenario is I have a file upload functionality once the file is uploaded I am performing different operations on the file. During every stage of processing I am logging those activities in database. This works fine if the file is small. If the file is large say 100 MB it takes some time to load so in the mean time the mysql server reconnects and creates a new connection but the logging code still uses the old reference.  Error: Cannot enqueue Query after fatal error. So, my question is is there a way that i can use the new connection reference instead of the old one. There is a single function in which all the different phases of activities regarding file takes place. Any help is greatly appreciated. thanks</p>
  
  <p>Hi @paul, if you have seen the gist link you can see that I have the upload.on('begin', function (fileInfo, reqs, resp) { } where I have logged the activity that file upload process has begin. Once the file is uploaded upload.on('end', function (fileInfo,request,response) { } is triggered. I am also logging some activity here. As I said in my question, if the file is big the upload takes time. In the mean time a new MySql connection is created but the insert query in 'end' event still refers to the old myconnection. So, I wanted to know how can I use the new mysql connection reference in this scenario? I hope this has explained the scenario better.</p>
