How to Store data using 'INTO' Postgresql

Question

I want to store the value of this query inside a Stored Procedure:

select * from myname;

using

select * into mydata from myname

but an error "mydata" is not a known variable occurs. Is there a way to store those results into a variable in postgre?

Answer 1

Assuming you are trying to do this in the context of a PL/PgSQL function, then you have to declare the variable first.

CREATE OR REPLACE FUNCTION foobar() RETURNS void AS $$
DECLARE
    mydata RECORD;
BEGIN
    SELECT * INTO mydata FROM mytable;
    -- now do something with mydata
END
$$ LANGUAGE plpgsql;
