Adrian,
As each row in the table already has both a date column and a time column I
don't know if I 'really' need a timestamp. When would a timestamp be really
needed?
I would say the fact you are asking is an indication you might need it.
select ('10/19/2025'::date + '07:50'::time)::timestamptz;
Yes, I saw that on the doc page. This requires manually changing each
row in
the table rather than using a date/time condition/function to to create the
single timestamp column. So, apparently there's not a way to modify the
table other than by hand.
1) Again you seem to be establishing a need for combined value.
2) Not sure how you do "...date/time condition/function to to create
the single timestamp column" without creating a column?
If you meant creating a timestamp value then I point you at my original
post and:
"2) If you really need a timestamp the work is already done, instead of
building on the fly."
Doing the one time change to add a timestamp field to the table and then
do the UPDATE of date + time to populate it versus calculating it every
time you need the value. Of course moving forward you would need to
change the code that INSERTs new values to use a timestamp instead of a
date and a time value.
Thanks,
Rich
