Hi,
I assume one field will always be NULL and one will always has data in it.
select coalesce(fieldA, fieldB) from table

Hi,
In my table, I have fieldA and fieldB. At any point in time, only one
of these fields can have data in it. The other is NULL.
Instead of "select fieldA, fieldB from table", I want it to return
either fieldA or fieldB depends on whether it is NULL or not.
The reason is because I want to use "select
array_to_string(array_accum(field A or field B) ,',') from table.
Is it possible to do it that way?
Thanks,
JB
