i asked this same question once and somehwere in the archives is a post by John Holmes that shows an example of how mysql allows db joins. its from last month i believe.... http://marc.theaimsgroup.com/?l=php-db but in short, mysql does support this using ..... db.table.field hth Jeff "Mike Tallroth" <mike.tallroth@pl To: php-db@lists.php.net exus.com> cc: Subject: JOIN across db's in MySQL 09/18/2003 10:47 AM In the big scheme of things, I need several functions to be performed by a web interface / database system. In an attempt to maintain some sense of order, I'm hoping to divide common data into a seperate MySQL database away from the function specific data. For example, I need to do project allocation and vendor quality tracking. These functions are generally unrelated but call on similar data (people in the group). My plan was to create a MySQL database called "admin" which contained people, customers, locations, addresses, etc, and seperate databases for each of the other functions projectallocation, vendorquality, etc. The problem I'm seeing is that there is no clean way of creating queries across database boundaries. Does PHP support this and I'm not seeing it? Does anyone know of third party code that accomplishes this "manually"? Am I out in left field on my desire to setup the database structure this way? thanks, -- Mike Tallroth Engineering Supervisor Test DesignCenter Plexus Technology Group Neenah, WI mike.tallroth @plexus.com 920-751-5418 -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
