Eliot is right, but it can all be done in the Links SQL admin, no need to edit def files.
Go to "Database -> Links -> Properties" then click on "URL". Then set "Not Null" to "No", and remove anything that is in "Form Regex". That should do the job.
As for displaying: you want to edit the template "link.html". Use something like
<a href="<%URL%>"><%Title%></a>
<%else%>
<%Title%
<%endif%>
