Re: [GENERAL] PL/PGSQL

Hi Jens.

First of all "select ... into ..." creates a new table and you can't use
existing table after "into".
And second - syntax errors in your function.
So, you must do something like:

create function insert_history () returns opaque as '
declare
rec record;
begin
for select x into rec from test1 where free=\'t\' loop
insert into history (field1, field2, ... )
values (rec.field1, rec.field2, ...);
end loop;
end;
' language 'plpgsql';

Or consider a rule for soving this task.

Sincerely yours, Yury.
