Query Generation

Question

DB : 10.2
Have two tables
1st Table : POS_ROLES
POS_ROLE_ID     
POS_ROLE_DESCRIPTION
LAST_UPDATE_BY
LAST_UPDATE_TS
ISACTIVE
2nd Table : gbl_user_profile
USWIN
POS_ROLE_ID     
Would like to generate the output for all the roles, will description and count of users where they have granted with the roles..
SELECT a.pos_role_id pos_role_id, a.pos_role_description pos_role_description, a.isactive isactive, count(a.pos_role_id) count
FROM
postp.pos_roles a,
postp.gbl_user_profile b
WHERE
a.pos_role_id = b.pos_role_id
group by a.pos_role_id, a.pos_role_description, a.isactive
order by a.pos_role_id ;
By using above query getting output of all the roles which has been granted but not which is not granted.
Any suggestion ?

Hi,
!st - dont use to old Ansi Standard for the join.
2nd - Where condition should be use to filter the rows not to join the tables
SELECT pos_role_id, A.pos_role_description, A.isactive, COUNT (pos_role_id) COUNT
FROM postp.pos_roles A LEFT OUTER JOIN postp.gbl_user_profile b
USING (pos_role_id)
GROUP BY A.pos_role_id, A.pos_role_description, A.isactive
ORDER BY A.pos_role_id;
OR
SELECT Apos_role_id, A.pos_role_description, A.isactive, COUNT (B.pos_role_id) COUNT
FROM postp.pos_roles A LEFT OUTER JOIN postp.gbl_user_profile b
ON (A.pos_role_id=B.pos_role_id)
GROUP BY A.pos_role_id, A.pos_role_description, A.isactive
ORDER BY A.pos_role_id;
