To use this value you have to add a line to the database config array. If you do not specify a DSN string for a driver that requires it, CodeIgniter will try to build it with the ocbc of the provided settings.
This is useful for distributed applications where you might run manually written queries, and need the prefix to still be customizable by the end user.
This permits multiple CodeIgniter installations to share one database. A default table prefix that should be swapped with dbprefix.
odc For example, when using SQLite you will not need to supply a username or password, and the database name will be the path to your database file. Note If you do not specify a DSN string for a driver that requires it, CodeIgniter odhc try to build it with the rest of the provided settings.
If you are not using the query builder class, setting it to Codeignitef will utilize fewer resources when the database classes are initialized. The config settings are stored in a multi-dimensional array with this prototype: You can also set database connection values for specific environments by placing database.
It can be anything you want. Must be specified in lower case. You can also specify failovers for the situation when the main connection cannot connect for some reason.

Note that some CodeIgniter classes such as Sessions require Query Builder to be enabled to access certain functionality. If, for example, you run multiple environments development, production, test, etc. The reason we use a multi-dimensional array rather than a more simple one is to permit ovbc to optionally store multiple sets of connection values.
These failovers can be specified by setting the failover for a connection like this:.
The default setting is TRUE. CodeIgniter has a config file that lets you store your database connection values username, password, database name, etc.
An optional table prefix which will added to the table name when running Query Builder queries. The database port number.
Then, to globally tell the system to use that group you would set this variable located in the config file:.
Whether or not to use an encrypted connection. Note If you provide a DSN string and it is missing some valid settings e.
