If I have a table containing a date field, say:
create temporary table tmp1 as select now()::date as evtdate;
SELECT 1
select DATE_PART('year', evtdate)::integer as year from tmp1;
year
------
2024
(1 row)
Is there some way of doing something like the following?:
alter table tmp1 add column year integer generated always as
DATE_PART('year', evtdate)::integer STORED;
ERROR: syntax error at or near "DATE_PART"
LINE 1: ... tmp1 add column year integer generated always as DATE_PART(...
