title: How to see contents of Check Constraint on Oracle
body: <p>I did not create the database I'm working with, but I would like to see the details of a check constraint.</p>
  
  <p>I know a check constraint on a column is enforcing a set of specific values, and I'd like to know what those values are.  For example, if a check constraint is enforcing the character 'Y' and 'N', I want to be able to query the database and see that the accepted values are 'Y' and 'N.'</p>
  
  <p>Is this possible to do through a query?</p>
