Well, I thought this should indicate it: "And if there are 0 rows with stoptype = 1,
my select should return 1 row." but maybe I was a bit unclear...
The problem is that the log_stop table stores log values for x different kind of logs
separated with the stoptype field... And I am trying to design a report (a
master/detail type) where all the values from the order table should be shown with a
table listing the fields from log_stop beneath it...

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@xxxxxxxxxxxxxx)
