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.

<?php
public function columnExists($table, $column) {
  $schema = $this->introspectSchema($table);
  return !empty($schema['fields'][$column]);
}
?>
