mysqlpp::ScopedConnection

[Joel Fielder]

Hi Warren,

I've got a useful class which I use a lot when dealing with a connection 
pool, for example:

mysqlpp::ScopedConnection connection(pool);
mysqlpp::Query query(connection->query());
query << "SELECT 1";
query.execute();

It grabs the connection on construction and releases upon destruction, 
but it also provides operator->() so you can treat it as if it were a 
pointer to a Connection.

Would you like a patch?  If so, where would be an appropriate place in 
the library and are there any other gotchas?

Joel
