Destramic Posted August 10, 2015 Share Posted August 10, 2015 hey guys i have a few questions regarding my website that has the use of multiple databases....at the moment my site is ran off one mysqli connection and before executing a query i change the database depending on if its my authentication script, geoip, framework etc. what i'm worried about is performance issues....i could have a new connection for each database or continue to have one connection for the whole site and change database when needed...what is the best practice please? thank you.

Barand Posted August 10, 2015 Share Posted August 10, 2015 The connection is to the server so if the databases are on the same server then a single connection is sufficient. You can, if you want, mix databases in a single query if on the same server SELECT ... FROM database1.tableA as a INNER JOIN database2.tableB as b Quote Link to comment https://forums.phpfreaks.com/topic/297708-website-with-multiple-databases/#findComment-1518406 Share on other sites More sharing options...
