Обсуждение: select into multiple variables

I have a select statement in a pgpsql function that returns two columns
and a single row.
I would like to place the two values into two variables in a single
statement, but so far I couldn't find out what is the syntax for that.

I tried a couple of combinations of this but had no luck:

SELECT INTO
 instrumentheaderid_arg, subjectgroupheaderid_arg,
 instrumentnormheader.instrumentheaderid,
 instrumentnormheader.subjectgroupheaderid
FROM
 instrumentnormheader
WHERE instrumentnormheaderid=3

Thanks for the help.

ugh, sorry, found it

SELECT INTO
instrumentheaderid_arg, subjectgroupheaderid_arg
instrumentnormheader.instrumentheaderid,
instrumentnormheader.subjectgroupheaderid
FROM
  public.instrumentnormdetail
  INNER JOIN public.instrumentnormheader ON
(public.instrumentnormdetail.instrumentnormheaderid =
public.instrumentnormheader.instrumentnormheaderid)
WHERE instrumentnormdetailid=instrumentnormdetailid_arg;
