hello everybody
i have problem for create a table users :
Quote:Unable to select the specified database: cms
Filename: C:\wamp\www\CodeIgniter\system\database\DB_driver.php
Line Number: 140
my files database.php
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

| -------------------------------------------------------------------
| DATABASE CONNECTIVITY SETTINGS
| -------------------------------------------------------------------
| This file will contain the settings needed to access your database.
|
| For complete instructions please consult the 'Database Connection'
| page of the User Guide.
|
| -------------------------------------------------------------------
| EXPLANATION OF VARIABLES
| -------------------------------------------------------------------
|
| ['hostname'] The hostname of your database server.
| ['username'] The username used to connect to the database
| ['password'] The password used to connect to the database
| ['database'] The name of the database you want to connect to
| ['dbdriver'] The database type. ie: mysql. Currently supported:
mysql, mysqli, postgre, odbc, mssql, sqlite, oci8
| ['dbprefix'] You can add an optional prefix, which will be added
| to the table name when using the Active Record class
| ['pconnect'] TRUE/FALSE - Whether to use a persistent connection
| ['db_debug'] TRUE/FALSE - Whether database errors should be displayed.
| ['cache_on'] TRUE/FALSE - Enables/disables query caching
| ['cachedir'] The path to the folder where cache files should be stored
| ['char_set'] The character set used in communicating with the database
| ['dbcollat'] The character collation used in communicating with the database
| NOTE: For MySQL and MySQLi databases, this setting is only used
| as a backup if your server is running PHP < 5.2.3 or MySQL < 5.0.7
| (and in table creation queries made with DB Forge).
| There is an incompatibility in PHP with mysql_real_escape_string() which
| can make your site vulnerable to SQL injection if you are using a
| multi-byte character set and are running versions lower than these.
| Sites using Latin-1 or UTF-8 database character set and collation are unaffected.
| ['swap_pre'] A default table prefix that should be swapped with the dbprefix
| ['autoinit'] Whether or not to automatically initialize the database.
| ['stricton'] TRUE/FALSE - forces 'Strict Mode' connections
| - good for ensuring strict SQL while developing
|
| The $active_group variable lets you choose which connection group to
| make active. By default there is only one group (the 'default' group).
|
| The $active_record variables lets you determine whether or not to load
| the active record class
*/
