DB - Query(limit) vs. LimitQuery() in MySQL

Hi group I'm using the DB-package in PEAR and was wondering which of the two approaches are most efficient: $res->Query('SELECT * FROM table LIMIT a, b'); $res->LimitQuery('SELECT * FROM table', a, b); I'm using MySQL as DBMS giving me the option to use LIMIT directly in the query which is quite efficient since I don't have to retrieve all the rows in the table - at least this is what I think is the case :-) The problem is that I'm using the DB package to provide portability and allow me to more easily switch the DBMS if it becomes necessary and I don't know if MySQL's way of using LIMIT is "industry-standard"? Does LimitQuery take advantage of MySQLs features when executing the query? To sum all of the above up: Which one should I use and what are the pros and cons of the methods? Cheers, Tommy Ipsen
