Hi,
you may try;
execute 'select ' ||
f || '(' || p || ')' into res;

I want to create a function in PL/SQL as
CREATE OR REPLACE FUNCTION "f_do" (text, double precision[]) RETURNS

DECLARE
f text := $1;

BEGIN
SELECT f(p) into res;
RETURN res;
END;' LANGUAGE "plpgsql"
STABLE
RETURNS NULL ON NULL INPUT
SECURITY INVOKER
But it does not work.
I try EXECUTE f || ' ( ' || p || ' );' INTO res
But is does not work too.
There is no function to convert double precision[] to text.
Is it possible to do this without converting the array of double to
text ?
what is are the arguments for function f()?
Also, if you are using 8.0+, you can do dollar quoting and named input
parameters. If not, i think using alias is preferred to assignment
for giving names to arguments.
