What's wrong with this query that used to work great:
webunl=> SELECT DISTINCT count(*),id_curso AS LINK,titulo AS
TITULO_CARRERA,admin_view_facultades.nombre AS FACULTAD,
webunl-> duracion/12 AS DURACION FROM admin_view, admin_view_facultades
webunl-> WHERE admin_view_facultades.id_carrera=admin_view.id_curso
webunl-> GROUP BY id_curso,titulo,admin_view_facultades.nombre,duracion/12
webunl-> ORDER BY id_curso ASC LIMIT 20 OFFSET 0 ;count | link | titulo_carrera | facultad
| duracion
-------+------+-----------------------------+--------------------------------+---------- 1 | 1 | Ingenieria en
informatica | Facultad de Ingenier<ED>a
Qu<ED>mica | 4 1 | 2 | Licenciatura en Matematicas | Facultad de Ingenier<ED>a
Qu<ED>mica | 4
(2 rows)
webunl=>
As you can see count(*) is 1, even seeing 2 rows selected. What's wrong?
All that chenged is that I recompiled postgreSQL 7.1.2 with the patch from
the rewriteHandler.c file.

Porqué usar una base de datos relacional cualquiera,
si podés usar PostgreSQL?
