Hello,
I have an problem understanding a simple query:
For example I have the following:
select count(*) from foo;
gives me 1000
select count(*) from foo where bar = 'Mr Spock';
gives me 5
select count(*) from foo where NOT bar = 'Mr Spock';
gives me 857
Why I'm not getting 955 for the last query ?
Any idea ?
Kindly regards
Lutz
