Build a condition to match a table name against a standard information_schema.

MySQL uses databases like schemas rather than catalogs so when we build a condition to query the information_schema.tables, we set the default database as the schema unless specified otherwise, and exclude table_catalog from the condition criteria.

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/mysql/schema.inc, line 35

<?php
protected function buildTableNameCondition($table_name, $operator = '=') {
  $info = Database::getConnectionInfo();

  if (strpos($table_name, '.')) {
    list($schema, $table_name) = explode('.', $table_name);
  }
  else {
    $schema = $info['default']['database'];
  }

  $condition = new DatabaseCondition('AND');
  $condition->condition('table_schema', $schema);
  $condition->condition('table_name', $table_name, $operator);
  return $condition;
}
?>
