Hi
I would like to create a function that passes a tablename as a variable, but I do not know what 'datatype' a tablename is supposed to be.

CREATE FUNCTION find_max_id(int4, tablename?) RETURNS int4
AS 'Select max($1) FROM $2'
LANGUAGE 'sql';

When I put text as the datatype for the tablename the error was a problem near $2.
Could someone please help me.
Thanks
Julie Hunt
