Hi,
I have a table
select id, config_id, start_day, end_day, start_time, end_time from config;
id | config_id | start_day | end_day | start_time | end_time
-----+-----------+-----------+---------+------------+----------
1 | 101 | Mon | Sun | 08:30:00 | 18:00:00
2 | 101 | Mon | Sun | 18:00:00 | 22:00:00
3 | 555 | Mon | Fri | 08:30:00 | 16:00:00
I'd like to write a query to generate the following... is it possible at all?
config_id | day | start_time | end_time
