is there any possibility to count the number of rows resulting from a
grouped query (from a view containing a grouped query) ?
CREATE TABLE tmp (a int, b int, c text);
INSERT INTO tmp values (1, 1, 'a');
INSERT INTO tmp values (2, 1, 'b');
INSERT INTO tmp values (1, 2, 'c');
INSERT INTO tmp values (2, 2, 'd');
CREATE view damn as select a, b from tmp group by a, b;
I have no rights to access tmp directly, I have to use the view !!!
praxis=# select * from damn where b=2;
a | b
1 | 2
2 | 2
okay, this is what I want.
praxis=# select count(*) from damn where b=2;
I dont want the aggregate function to be used on each group, I want it
to count all the rows.
IMHO the view should act as a table (and therefor should UNGROUP the
P.S.: I use 7.0.3
P.P.S.: How stable is 7.1
