  <p>facing this issues while
  executing tpt to load data from csv to Teradata DB. Could you please
  help me in resolving this issue.</p>
  <p>simple cast logic is used to convert data type from Varchar to decimal and timestamp(0).
  and if i hardcode the value like <code>(cast(20.0) as decimal(12,2) )</code> its working fine.
  Failure case <code>cast(column_nm) as decimal(12,2)</code> .</p>
