Schema API

A Drupal schema definition is an array structure representing one or more tables and their related keys and indexes. A schema is defined by hook_schema(), which usually lives in a modulename.install file.

public function addUniqueKey(&$ret, $table, $name, $fields) {
  $schema['unique keys'][$name] = $fields;
