Desing Help: mutliple databases, different sql

Hi All

I have a design question I need some assistance with. I'm building an app that needs to query multiple database with different sql statements. The app has a search page where a user will enter a search term and select a database, then depending on the database chosen I must execute a specific sql statement against a specific db. The db connection info and sql statements are all located in a config file.

How can I design the app so that I can open a db connection and execute the sql making sure I comply with the framework best practists (should I make a plugin etc).

Thanks for any help much appreciated!


You can use a group... see as http://ellislab.com/codeigniter/user-gui...ation.html

i.e.: $active_group = "test";

Try and send me a feedback! Ciao

The docs are very clear on how to create multiple simultaneous DB connections. You simply need to implement those methods:

$DB1 = $this->load->database('group_one', TRUE);
$DB2 = $this->load->database('group_two', TRUE);

group_one and group_two corresponds to the database.conf file that contains your DB configurations for each DB group.

Your queries could be structured as $sql1 and $sql2:




depending on your needs.

The docs can be found here: http://ellislab.com/codeigniter/user-gui...cting.html

Hope this is helpful.


Thanks for all your replies I learnt allot. I have another question, the config file that has all the db info and reated sql is kinda like a library, I need user to be able to download updates etc. Having said that is the CI specific config file the best place for the db data.

Thanks again!
