You will use the mysql_select_db() function. It sets the currently active database. You will call
this function each time you wish to change which database is being used prior to issuing a query.
You need to open only one connection as long as the databases are on the same server. If you are
using multiple servers, you will require a connection to each with unique resource link_identifiers.
Then you will have to include the desired resource link_id in each call to mysql_select_db().
There is no need to close and re-open connections between each use.
