I want to create the following tabe in Oracle 11g but I get the following error: `Oracle SQL error ORA-00907: missing right parenthesis`. Why is this happening?

```
CREATE TABLE DOCUMENTATION
( 
  NAME varchar2(200) not null,
  VALUE varchar2(500) not null,
  QUERY varchar2(200) not null,
  INSERTDATE date(7) not null
);

```
