Connect multiple tables in different databases? MySql

Question

Hey, I am looking for a good way to connect to at least 2 databases in mysql using php and gathering information within each of those databases from tables.

The tabl

Answer 1

I always use the full name for my tables. So if a table named tablea is in a database called dba, I would do the following query:

SELECT * FROM dba.tablea

This allows you to switch databases really easily. If you don't want to remember to do this, I also suggest defining constants for each of your tables, at which time you can put it in.
