21 is the number of IDS that I wanna perform that COPY command....
that didn't answer my question. if you call your function like SELECT myfunction(21); as you showed, where are those 21 ID's coming from?
I don't know what u need, mate:
CREATE or REPLACE FUNCTION function(integer)
RETURNS void AS $$
declare
crtRow record;
begin
FOR crtRow in EXECUTE 'select DISTINCT(account_id) from backup_table WHERE migrated = 1 AND account_id IN '|| $1
LOOP
COPY
(SELECT * FROM backup_table WHERE migrated = 1 AND account_id = crtRow.account_id)
TO '/var/lib/pgsql/' || crtrow.account_id || '.csv';
end loop;
end
Isn't this what u wanna know?$$ language 'plpgsql';
select DISTINCT(account_id) from backup_table WHERE migrated = 1
