Hi, all. Yep, I'm still alive and kicking.
I need to compute a month-to-date average for the column “average wait
time”. The time has been populated in the warehouse as character, and
is in the format mm:ss
I want to do something along these lines
to_char( (select avg(cci.WAIT_TIME) from OPS_MART.CIRCINFO cci
where to_char(cci.CIRCDATE , 'YYMM') = to_char(cd.DASH_DATE -1 , 'YYMM')
but to do this, I need to first convert from character into something useful.
I tried to_timestamp, which gives me
select circdate, to_timestamp(wait_time, 'mi:ss') from circinfo
18-MAY-09 01-MAY-09 12.01.52.000000000 AM
Which I don’t find particularly useful.
Any ideas??
Thanks for any help!!
