I get an SQL syntax error when I use a foreign key table contraint. Is this a known problem or am I doing something wrong?

create table BAR (
        ID      int
);

create table FOO (
        ID      int,
        NAME    CHAR(32)
)
foreign key (ID) references BAR(ID) on delete cascade;

This causes the following exception:

java.sql.SQLException: create table FOO (  ID    int,  NAME      char(32))foreign key (ID) references BAR(ID) on delete cascade
 Don't understand SQL after: "on"
 Expected: "null" found: "on"

Either removing the "on delete cascade" or attaching the constraint to the column does work.

Thanks
