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.

Code

includes/database/pgsql/schema.inc, line 605

<?php
public function getComment($table, $column = NULL) {
  $table = $this->connection->prefixTables('{' . $table . '}');
  // Don't use {} around pg_class, pg_attribute tables.
  if (isset($column)) {
    return db_query('SELECT col_description(oid, attnum) FROM pg_class, pg_attribute WHERE attrelid = oid AND relname = ? AND attname = ?', array($table, $column))->fetchField();
  }
  return db_query('SELECT obj_description(oid, ?) FROM pg_class WHERE relname = ?', array('pg_class', $table))->fetchField();
}
?>
