Drupal error when creating table - database

Question

I'm trying to create a new table in a .install module, here is what I do :
$schema['commission_summary'] = array (
'description' => 'Récapitulatif des commissions',
'fields' => array(
'commission_summary_id' => array(
'description' => 'ID de commission',
'type' => 'serial',
'unsigned' => TRUE,
'not null' => TRUE,
),
'product_id' => array(
'description' => 'ID du produit lié',
'type' => 'int',
'not null' => TRUE,
'default' => 0,
),
'date_depart' => array(
'description' => 'Date du debut du voyage',
'type' => 'int',
'not null' => TRUE,
'default' => 0,
),
'prestataire' => array(
'description' => 'ID du partenaire lié (Agence)',
'type' => 'int',
'not null' => TRUE,
'default' => 0,
),
'nb_participant_total' => array(
'description' => 'Nombre de participants total',
'type' => 'int',
'not null' => TRUE,
'default' => 0,
),
'nb_participant_agence' => array(
'description' => 'Nombre de participants de l\'agence ',
'type' => 'int',
'not null' => TRUE,
'default' => 0,
),
),
'primary key' => array('commission_summary_id'),
'indexes' => array(
'product_id' => array('product_id'),
'partner_id' => array('prestataire')
),
);
return $schema;
and
function ga_commission_update_7101() {
$table = 'commission_summary';
$schema = drupal_get_schema_unprocessed('commission_summary', $table);
db_create_table('commission_summary', $schema);
}
The problem is that I get an error but I don't know why, my syntax seems good no ?
I created some other table like that so I don't understand why this times it's not working
this is the error that i get :
Failed: PDOException : SQLSTATE[42000]: Syntax error or access violation:
1064 You have an error in your SQL syntax; check the manual that

You need to define your table in your hook_update_n, this will work:
function ga_commission_update_7101() {
$table = array(
'description' => 'Récapitulatif des commissions',
'fields' => array(
'commission_summary_id' => array(
'description' => 'ID de commission',
'type' => 'serial',
'unsigned' => TRUE,
'not null' => TRUE,
),
'product_id' => array(
'description' => 'ID du produit lié',
'type' => 'int',
'not null' => TRUE,
'default' => 0,
),
'date_depart' => array(
'description' => 'Date du debut du voyage',
'type' => 'int',
'not null' => TRUE,
'default' => 0,
),
'prestataire' => array(
'description' => 'ID du partenaire lié (Agence)',
'type' => 'int',
'not null' => TRUE,
'default' => 0,
),
'nb_participant_total' => array(
'description' => 'Nombre de participants total',
'type' => 'int',
'not null' => TRUE,
'default' => 0,
),
'nb_participant_agence' => array(
'description' => 'Nombre de participants de l\'agence ',
'type' => 'int',
'not null' => TRUE,
'default' => 0,
),
),
'primary key' => array('commission_summary_id'),
'indexes' => array(
'product_id' => array('product_id'),
'partner_id' => array('prestataire')
),
);
db_create_table('commission_summary', $table);
}
