Hi!
Try this one:
SELECT
a.ug_id,
b.ug_users[a.generate_series]
FROM
(SELECT
ug_id,
generate_series(1, array_upper(ug_users, 1))
FROM
user_group
) AS a,
user_group AS b
WHERE
a.ug_id = b.ug_id;

Hi!
I have such table:
user_group
---------------------------------
ug_id -> serial primary key
ug_users -> int4[]
For example table has such rows:
ug_id | ug_users
-------+--------------
1 | { 2,5,6 }
2 | { 3,4,9 }
I want to write SQL-query or write user defined function to get such
result (extract array values):
ug_id | ug_users
-------+--------------
1 | 2
1 | 5
1 | 6
2 | 3
2 | 4
2 | 9
Help please to solve this problem.
