title: ORA-30089 when execute CREATE TABLE with a DATE type field
body: <p>I'm getting the following error when creating the following table:</p>
  
  <pre><code>CREATE TABLE EVENTO(
      ID_EVENTO NUMBER PRIMARY KEY,
      ID_COMPLEJO NUMBER NOT NULL,
      N_COMISARIOS NUMBER,
      FECHA_EVENTO DATE,
      N_PARTICIPANTES NUMBER,
      DURACION INTERVAL,
      EQUIPAMIENTO VARCHAR2(255),
      FOREIGN KEY (ID_COMPLEJO) REFERENCES COMPLEJO
  );
  </code></pre>
  
  <p>I do not know if it is because of Oracle's permission to the user because I am on the desktop and here he does not let me create the table.</p>
