Code
public function tableExists($table) {
$condition = $this->buildTableNameCondition($table);
$condition->compile($this->connection, $this);
// Normally, we would heartily discourage the use of string
// concatenation for conditionals like this however, we
// couldn't use db_select() here because it would prefix
// information_schema.tables and the query would fail.
// Don't use {} around information_schema.tables table.
return (bool) $this->connection->query("SELECT 1 FROM information_schema.tables WHERE " . (string) $condition, $condition->arguments())->fetchField();
