Hi, For example, CREATE TABLE inventory_item ( name text, supplier_id integer REFERENCES suppliers, price numeric CHECK (price > 0) ); produces the following type automatically CREATE TYPE inventory_item AS ( name text, supplier_id integer, price numeric ); but I'd also like to have a type with an extra column for certain functions CREATE TYPE inventory_item2 AS ( name text, supplier_id integer, price numeric, size integer ); but it would be handy if I could reuse inventory_item instead of having to retype the whole lot. I can't work out or find the right syntax, can anyone show me how? Any help would be much appreciated. Regards Iain |
