HI,
is there a way to limit access for some users only to certain records?
e.g. there is a customer table and there are account-managers.
Could I limit account-manager #1 so that he only can access customers

No luck. Obviously SUM expects an

Hi,
It works, but you should use a recent version:
test=*# select count(1) over (), i from foo;
count | i

8 | 7
8 | 9
