mysql_select_db -- Select a MySQL database


bool mysql_select_db ( string database_name [, resource link_identifier])

Returns TRUE on success or FALSE on failure.

mysql_select_db() sets the current active database on the server that's associated with the specified link identifier. If no link identifier is specified, the last opened link is assumed. If no link is open, the function will try to establish a link as if mysql_connect() was called without arguments, and use it.

Every subsequent call to mysql_query() will be made on the active database.

Example 1. mysql_select_db() example


= mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!
$link) {
'Not connected : ' . mysql_error());

// make foo the current db
$db_selected = mysql_select_db('foo', $link);
if (!
$db_selected) {
    die (
'Can\'t use foo : ' . mysql_error());

See also mysql_connect(), mysql_pconnect() and mysql_query().

For downward compatibility mysql_selectdb() can also be used. This is deprecated however.
