title: Converting and altering Oracle table columns
body: <p>I need help for specific question.</p>
  
  <p>I need to write some Oracle Database procedure, which will do next:</p>
  
  <ul>
  <li>Receiving a table name as a parameter; </li>
  <li>Taking all fields with numeric value (number/bignumber/numeric/etc.) excepting primary key;</li>
  <li>Convert these columns to to DATE format;</li>
  <li>Add these new formatted columns to this table (I mean an ALTER TABLE ADD COLUMN).</li>
  </ul>
  
  <p>How can I do this?</p>
