Hi,
It’s my test DB, the version is PostgreSQL 9.4beta2. I’m testing with
nested hstore feature.
testdb=# \d+ test
Table "public.test"
Column | Type | Modifiers | Storage | Stats target | Description
--------+--------+-----------+----------+--------------+-------------
id | text | | extended | |
stats | hstore | | extended | |
testdb=# select * from test;

"www.strawberrynet.com"=>"{visits=>2.11221003268,pages=>4.22442006537,duration=>197980.836904}"
(1 row)
So how did you get the above values in?
testdb=# select (each(channel)).key,(each(channel)).value from visits;
key | value
-----------------------+----------------------------------------------------------------------
www.ask.com |
{visits=>2.11221003268,pages=>4.22442006537,duration=>197980.836904}
www.strawberrynet.com |
{visits=>2.11221003268,pages=>4.22442006537,duration=>197980.836904}
(2 rows)
Did you change tables in the above?
The question is how can I get visits/pages/duration separately from the
value column so that I can do a sum on those metrics individually.
Thank you!
Suya
