Re: [GENERAL] Dynamically access to field on a RECORD variable

[Ricardo Vaz Mannrich]

If it's not possible, can I create a function that gets a RECORD and a
tablename and returns the correct value. For example:

CREATE FUNCTION my_value(TEXT, RECORD) RETURNS TEXT AS '
  DECLARE
    table_name ALIAS FOR $1
    rec ALIAS FOR $2
  BEGIN
    IF (table_name = 'my_table1') THEN
      RETURN rec.my1_field;
    ELSIF (table_name = 'my_table2') THEN
      RETURN rec.my2.field;
    ...
  END;
' LANGUAGE plpgsql;
