Hi Hackers
How hard would it be to add support for LIKE syntax, similar to table
def in field list declaration for generic record functions
What I'dd like to be able to do is to have a generic json_to_record
function
CREATE OR REPLACE RECORD json_to_record(json) RETURNS RECORD AS $$
...
$$ LANGUAGE ... ;
and then be able to call it like this
insert into test2
select * from json_to_record(jrec json) as (like test2);
ERROR: syntax error at or near "like"
instead of explicitly spelling out the structure of table test2 in the
AS part.
insert into test2
select * from json_to_record(jrec json)
as (id int, data2 test, tstamp timestamp);
INSERT 0 1
PS.
As a pie-in-the-sky wish I'd prefer of course even simpler syntax of
insert into test2 json_to_record(jrec json);
or at least
insert into test2 json_to_record(jrec json)::test2;
:)
