Hi, why doesn't work good with first() ? if you do: db(db.table.xx==request.vars.xx).select().first() it will return just the first record, if it doesn't is because the record does not exist.
other way to do this is with limitby: db().select(db.person.ALL, limitby=(0, 2)): http://www.web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#orderby-groupby-limitby-distinct-having-orderby_on_limitby-join-left-cache <http://www.web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#orderby-groupby-limitby-distinct-having-orderby_on_limitby-join-left-cache> Cheers.
