Oh. That doesn't work for me as i generate the query dynamically and don't know their structure...
Maybe there is an easy way to get the cursor structure (column - value, column - value....)?
Or should i give up on cursors and try something else? Some Google search hint that hstore could be my saviour :)

Ok, now i am getting this:
ERROR: could not identify column "151" in record data type
Raise notice show that the column exists.
Any other way around it?
hmm - it doesn't work for generic record - it should be typed row value.
postgres=# create table foo("123" int);
CREATE TABLE
postgres=# create table boo("123" int);
CREATE TABLE
insert into boo values(20);
INSERT 0 1
postgres=# do $$
declare r boo; -- cannot be generic record
begin
for r in select * from boo
loop
execute $_$insert into foo values($1."123")$_$ using r;
end loop;
end;
$$;
DO

That didn't work for me:
ERROR: syntax error at or near "$"
LINE 1: ...ibute_id, set_id ) (select $."151", '...
should be $1

Hello. Didn't find dedicated plpgsql list, so decided to post question here.
I am trying to create a function that will pick up some values from cursor and execute them as a dynamic query.
However, once i use EXECUTE, its seems to be ignoring the existence of cursor and try to pick up values from table.
Basically:
insert into mytable ( value, attribute_id, set_id ) (select rec."151", '201', '1')
works, but
execute 'insert into mytable ( value, attribute_id, set_id ) (select rec."151", ''201'', ''1'')'
Dynamic queries are executed in own space and there are not direct access to plpgsql variables.
please, try: execute 'insert into mytable ( value, attribute_id, set_id ) (select $1."151", ''201'', ''1'')' using rec;
Regards

fails with
ERROR: missing FROM-clause entry for table "rec"
LINE 1: ...ibute_id, set_id ) (select rec."151",...
Is there any way around it? Or should i just give up and do it some other way?
