title: Oracle DB trigger-based synchronization error in history store table type 0?
body: <p>We are doing a <em>trigger-based</em> synch with DB Convert studio tool from Oracle as a source. This method creates triggers on each table and a <code>history_store</code> table.</p>
  <p>But, the software that uses the source oracle DB gives the following error and refuses to work:</p>
  <blockquote>
  <p>Unknown type (table: history_store, column: pk_date_dest, type: 0)</p>
  </blockquote>
  <p>The <code>pk_date_dest</code> column is initialized as <code>&quot;pk_date_dest&quot; NVARCHAR2(400) NOT NULL</code>. What might be the reason for this <em>type 0</em>?</p>
