currently in case APPROX_TABLE_SIZE is not given, select count is performed on the table which is highly inefficiently. a better fallback would be to use information_schema.tables more specifically:

select TABLE_ROWS from information_schema.tables where table_schema="helloworld" and table_name="ilapahsi"
