[PHP-DB] join across databases - how to select databases?
I have looked all over the web but can't find an example *in php* for connecting to a mysql server, selecting database(s), and issueing a query which joins across databases. I already know the SQL required to achieve a multiple database query. My question is about how many calls to mysql_select_db() are required, does order matter, etc. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] join across databases - how to select databases?
I assume something like the following would work, regardless of whether/how you've called mysql_select_db() SELECT t1.column FROM database1.table1 t1 JOIN database2.table2 t2 ON t1.id = t2.id If you have something working from the MySQL command line, then it's going to work from mysql_query() with the same exact syntax. You are indeed correct. I had a bug in my join syntax. How embarrassing. For the record, you don't even have to call mysql_select_db() at all. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
