FAQ
Hi there,

I'm currently developing a GUI for a network monitor. I have to plot
data taken from a MySQL database. For GUI I use wxPython, for plotting
Matplotlib. The plotting has to be realtime, so
I have to query the database periodically. I don't have enough
experience in programming and I would need some advice about the best
approach in this matter.

I tried to solve it using wx.Timer but from time to time MySQL server
doesn't repond to queries. I use one db connection for all my queries.
I also tried a threads approach but because I don't know how to use
them the result was worse.

Any sugestion will be highly apreciated.

Alina

    What is the error returned from MySQL when it is not responding to queries?

    Hi Stach,

    The error is "Lost connection to MySQL server during query".

    I solved the problem by using a more recent version of MySQLdb,
    compatible with MySQL 5.0.
