What is the correct order for adding an auto-increment to a table? Obviously this is not it:

db_drop_primary_key($ret, 'client_activity');
db_add_field($ret, 'client_activity', 'id', array(
        'type' => 'serial',
        'not null' => TRUE,
        'description' => 'Primary Key: Unique row ID.',
        ));
db_add_primary_key($ret, 'client_activity', 'id');
db_add_index($ret, 'client_activity', 'tnt', array('timestamp', 'nid', 'type'));

This gets these errors at update.php:

user warning: Incorrect table definition; there can be only one auto column and it must be defined as a key query: update_sql /* admin : update_sql */ ALTER TABLE client_activity ADD `id` INT auto_increment DEFAULT NULL in C:\www\webapps\drupal6\includes\database.mysql-common.inc on line 298.

user warning: Unknown column 'id' in 'client_activity' query: update_sql /* admin : update_sql */ ALTER TABLE client_activity CHANGE `id` `id` INT NOT NULL auto_increment in C:\www\webapps\drupal6\includes\database.mysql-common.inc on line 520.
