Thanks.

Where is the f_dayofmonth function located (or have you just made
that up as an example?)

I was thinking of returning a date and the number of entries on that
day, i.e casting the timestamp using:

CAST(TIME_STAMP as DATE)

I've just tried:

select CAST(ts as date), count(*) as entries
from run_log
group by CAST(ts as date)
having entries > 0

but it complains about the group by entry - 'Unknown toekn CAST'
