title: Restrict varchar() column to specific values?
body: <p>Is there a way to specify, for example 4 distinct values for a varchar column in MS SQL Server 2008?</p>
  
  <p>For example, I need a column called Frequency (varchar) that only accepts 'Daily', 'Weekly', 'Monthly', 'Yearly' as possible values</p>
  
  <p>Is this possible to set within the SQL Server Management Studio when creating the table?</p>
