If the two databases are on the same server, you can use joins to select data from multiple databases.
For instance: Database 1, Table A: -------------------- | id | name | -------------------- | 1 | George | | 2 | Mark | | 3 | Harry | -------------------- Database 2, Table A: -------------------- | id | name | -------------------- | 1 | Bill | | 2 | Henry | | 3 | Ford | -------------------- You can: SELECT a.name as db1Name, b.name as db2Name FROM Database1.TableA a LEFT JOIN Database2.TableA b ON a.id=b.id; Now you'll get: ----------------------- | db1Name | db2Name | ----------------------- | George | Bill | | Mark | Henry | | Harry | Ford | ----------------------- Hope this helps. - Jonathan -----Original Message----- From: Andy [mailto:[EMAIL PROTECTED]] Sent: Friday, January 04, 2002 5:50 AM To: [EMAIL PROTECTED] Subject: [PHP-DB] How to querry two db in a single statement?
