Björnke,

In other languages, in days gone by, it was good practice to keep the connection open if an application expected to issue multiple queries (such as a user driven reporting application) becuase there was overhead in setting up a connection and creating and opening a connection, executing a query, and closing a connection for each query could impact performance.

With the speed of today's servers, databases, clients, networks, and LiveCode, I am not sure connection maintenance for performance has any noticeable impact.

I am also interested because, even though I have tried to thoroughly trap for connection timeout error and execute code to reconnect, i still get "connection has gone away" errors every now and then. Instead of revising all my error raping code again, I am considering code for maintaining a persistent connection.

yours:

Some people like to keep alive their DB connections. But isn't it usually a 
more robust approach to close the connection as soon as the query is handled?

I've found it useful to handle mass-writes slightly differently, but there is 
normally so much happening, that the DB connection doesn't really idle at all.

I can think a few way to construct a "keep-alive" process to ensure that a connection to a MySQL 
database via the LiveCode database drivers doesn't time out. However, it occurs to me that folks who spend 
more time writing LiveCode MySQL applications than I may have come up with a "best" way to keep the 
connection from timing out, so I thought I would ask the list. An idle loop would do it, but using idle is 
not a "best" approach.

Any "best" approaches out there that someone cares to share?

Thanks!
