support ALTER TABLE AUTO_INCREMENT #35
Description
The query in this function (edit: example from a third-party plugin) produces an error (with the latest trunk):
public function reset_auto_increment_availability_table()
{
global $wpdb;
$tablename = $wpdb->prefix.$this->availability_tablename;
$row = $wpdb->get_row( "SELECT Max(sno) as max_sno FROM $tablename" );
$auto_increment = (int) $row->max_sno + 1;
// error_log('auto_increment : '.print_r($auto_increment,1));
$prepare_values = array( $auto_increment );
$query = $wpdb->prepare( "ALTER TABLE $tablename AUTO_INCREMENT = %d", $prepare_values);
$status = $wpdb->query($query);
}Here's the temporary workaround I used (thanks to ChatGPT):
public function reset_auto_increment_availability_table()
{
global $wpdb;
$tablename = $wpdb->prefix.$this->availability_tablename;
$row = $wpdb->get_row( "SELECT Max(sno) as max_sno FROM $tablename" );
$auto_increment = (int) $row->max_sno + 1;
// error_log('auto_increment : '.print_r($auto_increment,1));
$prepare_values = array( $auto_increment );
// Check if the database is SQLite
if ($wpdb instanceof WP_SQLite_DB) {
$query = $wpdb->prepare( "UPDATE sqlite_sequence SET seq = %d WHERE name = %s", array($auto_increment, $tablename));
} else {
$query = $wpdb->prepare( "ALTER TABLE $tablename AUTO_INCREMENT = %d", $prepare_values);
}
$status = $wpdb->query($query);
}
