Hi folks, me again.
I'm back with my availability and roster tables again.
I have:
Table "public.availability"
Column | Type
-----------+------------------------
aid | serial primary key
asid | integer
asdate | date
afdate | date
Table "public.roster_staff"
Column | Type | Modifiers
-------------+---------+---------------
rsdate | date | not null
rsgid | integer |
rsgsid | integer |
rssid | integer |
I want to do a join giving the details from the availability with a count of
roster_staff records within the range asdate->afdate for each staff member
(asid <-> rssid)
e.g.
availability
1 1 2007-04-01 2007-04-01
2 1 2007-04-10 2007-04-15
roster_staff
2007-04-01 4 5 1
2007-04-11 4 6 1
2007-04-13 4 3 1
2007-04-14 5 5 1
2007-04-15 5 6 1
giving
1 1 2007-04-01 2007-04-01 1
2 1 2007-04-10 2007-04-15 4
