Hi,
I am generating a json with json_object() function, and I would like to
omit the null or default fields from the output json (for compacity reasons)
When there is only one such field, I have used a "case when" like in
select
case when field2 is null then
json_object('field1', field1)
else
json_object('field1', field1, 'field2', field2)
end
...
but when there are multiple such optional fields, this approach becomes
unwieldy.
Anyone has a better idea?
Eric
