docs: {@inheritDoc}
  
  <p>Is the column a cash value? 6.1 introduced the cash/money type, which haven't been incorporated
  as of 970414, so I just check the type name for both 'cash' and 'money'
  
  @param column the first column is 1, the second is 2...
  @return true if its a cash column
  @exception SQLException if a database access error occurs
