/>Betreff:[PERFORM] Select-Insert-Query <br /><br />Hi, <br /><br />what is the most performant way to select for
examplethe first 99 rows of a table and insert them into another table... <br /><br />at the moment i do this: <br
/><br/>for userrecord in select * from table where account_id = a_account_id and counter_id = userrecord.counter_id and
visitortable_idbetween a_minid and a_maxid limit 99 loop <br />insert into lastusers (account_id, counter_id, date, ip,
hostname)values(a_account_id,userrecord.counter_id,userrecord.date ,userrecord.ip,userrecord.hostname); <br />end loop;
<br/><br />i think "limit" is a performance killer, is that right? but what to do instead <br /><br />thanks <br />bye
<br/>
