I've done a grep over the html documentation, and can't see anything regarding the limit feature (if I've just missed it and it is there could someone provide a pointer please?). I'm interested now in how this method actually works - is a query performed that reads all of the rows of a table into memory, and then the non-requested rows are discarded before the results are sent back? I'm interested in how this would work with a massive table...... Regards, Mark. -- Mark Jewiss Knowledge Matters Limited http://www.knowledge.com
