I have often wanted to do this. Years ago, when I was working with Sybase databases it was perfectly possible. You simplyqualified the table name with a database identifier as I recall eg <br /><br /> SELECT m.myfield from second_db.mytablem;<br /><br /> The advantages are that you may have two otherwise unconnected systems which need separatelybacking up etc but where one uses the other for lookup purposes (eg a reservations system uses a lookup to an accountssystem to get the customer name and number). <br /><br /> I have never understood why postgreSQL hasn't seen thisas a priority in development in more recent months. Maybe someone will enlighten us both!<br /><br /> Hilary<br /><br/> At 11:18 08/07/2004 -0400, Jodi Kanter wrote:<br /><br /><blockquote cite="cite" class="cite" type="cite">I am workingwith someone who uses MySQL and says that he has two separate databases in which he can query across.
