===== Syntax =====

<code php>
resource mysql_db_query(string $database, string $query [, resource $res])
</code>

//(PHP 4, PHP 5)//

^ $database | The name of the database to select before the query is run. |
^ $query | An SQL query to be run on the database server. |
^ $res | The MySQL database connection resource (returned by a call to [[mysql_connect]]. |
^ RETURNS | A database query result resource.  You may call the **mysql_fetch...** functions to read the data rows. |

===== What it Does =====

Peforms a query (**$query**) against the specified database (**$database**).  Unlike, [[mysql_query]], this function allows you to specify a database to use (in the event that more than one database is available to the user on the connection.)


===== Example =====

<code php>
// open the mysql resource
$res = mysql_connect($server, $user, $pass);

// the query to run
$sql = 'SELECT * FROM tblState';

// run a 'select' on the 'system' database
$data = mysql_db_query('system', $sql, $res);
