title: Read-only column with Linq2DB
body: <p>In my SQL Server table, I have a computed column. So for that column, I want to have only reading statements (like 'select') and no writing statements (like 'update') in generated code by Linq2DB.  </p>
  
  <p>What is the easiest way to do it? </p>
  
  <p>I don't want to all update/add statements explicitly to prevent writing to this column.</p>
