title: SQL "not a valid month"
body: <p>I have a table in sql as follows:</p>
  
  <pre><code>CREATE TABLE Reserves(
      sid INTEGER,
      bid INTEGER,
      day DATE,
      PRIMARY KEY (sid, bid, day),
      FOREIGN KEY (sid) REFERENCES Sailors,
      FOREIGN KEY (bid) REFERENCES Boats
  );
  </code></pre>
  
  <p>and I'm trying to insert into it:</p>
  
  <pre><code>INSERT INTO Reserves VALUES(22, 101, '01-01-1998');
  </code></pre>
  
  <p>But I get the error: ORA-01843: not a valid month</p>
  
  <p>This is an Oracle db.  I'm not sure what's wrong with my date format.</p>
