I just want to clarify that the following will always behave the way I
think it's supposed to behave:-
update tableA
set date_field = case when date_field is null then some_date
else date_field end;
If the current value of date_field for the current record is null then
set the date_field with some_date value otherwise keep the current
value of date_field.
Note: in the actual situation there'll be other fields that will
always be updated in addition to this one field that needs to be
conditionally updated.
