Hi,
what is the most performant way to select for example the first 99 rows of a table and insert them into another table... at the moment i do this: for userrecord in select * from table where account_id = a_account_id and counter_id = userrecord.counter_id and visitortable_id between a_minid and a_maxid limit 99 loop insert into lastusers (account_id, counter_id, date, ip, hostname) values(a_account_id,userrecord.counter_id,userrecord.date,userrecord.ip,userrecord.hostname); end loop; i think "limit" is a performance killer, is that right? but what to do instead thanks bye |
