Bug description:Multiple Queries on a single conenction
Description:
------------
Hi, trying to build a generic DB object handler for mySqli, and have hit an
issue where we can't have more than one open query on the same connection.
Is this a bug or 'expected behaviour'?
Looking at the mysqli.c source code, it looks like it should have been
possible, but it looks like the second object overwrites the first...
I have put a sample snippet below of what I am trying to achieve.... if
this helps.
Any help greatly appreciated....
