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
