From: absolutely_no_spam@rogers.com Can anybody think of an example where "select count(*) from..." is different from "select count(columnA) from...." in terms of performance? For example, what if columnA is indexed? Thanks in advance. -tk --- SoupGate-Win32 v1.05 * Origin: you cannot sedate... all the things you hate (1:229/2) |
