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
RETU
I am newbie. Could you give a example?
Thank you.

TIP 9: the planner will ignore your des
Hello,
It's not possible. Not in plpgsql. Its possible in plperl or plpython or
pltcl. But you can do
CREATE OR REPLACE FUNCTION my_fce(text) returns text AS $$
DECLARE _r RECORD;
BEGIN
FOR _r IN EXECUTE 'SELECT '||$1||' AS _c FROM my_table ...' LOOP
RETURN _r._c;
END LOOP;
END; $$ LANG
Supose I have this function
CREATE OR REPLACE my_func(TEXT) RETURNS text AS '
DECLARE
var_name ALIAS FOR $1;
rec RECORD;
BEGIN
SELECT * INTO rec FROM my_table WHERE my_key = 1;
-- Here is my problem
RETURN rec.var_name;
END;
' LANGUAGE plpgsql;
SELECT my_func('my_field')
