Multiple Database in CodeIgniter


Recommended Posts

Hi ..., I'm trying to implement multiple database in CI. My code Is here:



    $active_group = "default";
    $active_record = TRUE;
    $db['default']['hostname'] = "localhost";
    $db['default']['username'] = "root";
    $db['default']['password'] = "root";
    $db['default']['database'] = "ravelex";
    $db['default']['dbdriver'] = "mysql";
    $db['default']['dbprefix'] = "rvx_";
    $db['default']['pconnect'] = TRUE;
    $db['default']['db_debug'] = TRUE;
    $db['default']['cache_on'] = FALSE;
    $db['default']['cachedir'] = "";
    $db['default']['char_set'] = "utf8";
    $db['default']['dbcollat'] = "utf8_general_ci";
    $db['smf']['hostname'] = "localhost";
    $db['smf']['username'] = "root";
    $db['smf']['password'] = "root";
    $db['smf']['database'] = "smf";
    $db['smf']['dbdriver'] = "mysql";
    $db['smf']['dbprefix'] = "smf_";
    $db['smf']['pconnect'] = TRUE;
    $db['smf']['db_debug'] = TRUE;
    $db['smf']['cache_on'] = FALSE;
    $db['smf']['cachedir'] = "";
    $db['smf']['char_set'] = "utf8";
    $db['smf']['dbcollat'] = "utf8_general_ci";


The model is



    class user_model extends Model {
        private $ravelex_db;
        function user_model() {
            $this->ravelex_db = $this->load->database('default', TRUE);
        function find_all() {
            $q = $this->ravelex_db->get('users');
            return $q->result();

    class smf_user_model extends Model {
        private $smf_db;
        function smf_user_model() {
            $this->smf_db = $this->load->database('smf', TRUE);
        function find_all() {
            $q = $this->smf_db->get('members');
            return $q->result();


Controller tester



class mutipledb extends Controller {
        function mutipledb() {
        function index() {


There are some error, The first database uses the second database name. But it still use it's prefix.


The error is


A Database Error Occurred
    Error Number: 1146
    Table 'smf.rvx_users' doesn't exist
    SELECT * FROM (`rvx_users`)


But if I just load one model, It works. Why this could be happened ?

Help me please .....
