title: Why does it say ORA-14006: invalid partition name?
body: <p>I used this code on Oracle PL/SQL on version 13</p>
  <pre><code> ALTER TABLE instrument_balance_hist MODIFY  PARTITION BY RANGE( instrument_id )  INTERVAL (100)(
  partition p1 VALUE LESS THAN (100),
  partition p2 VALUE LESS THAN (200),
  partition p3 VALUE LESS THAN (300),
  partition p4 VALUE LESS THAN (400),
  partition p5 VALUE LESS THAN (500),
  partition p6 VALUE LESS THAN (600)
  );
  </code></pre>
  <p>The data type of instrument_id is number(6).</p>
  <p>It keeps saying invalid partition name and gives a red underline at 'BY'.</p>
