I have a long select table with quite a few joins

One of the joins I need to add is to have everything from assignments


JOIN to ContactEvents  on AssignmentID  = Assignment ID
and get everything FROM contact events where Assignment.StartDate < ContactEvent.ContactDate

LEFT JOIN      dbo.ContactEvents
          ON   Assignment.[Assignment Number] = dbo.ContactEvents.[Assignment Number]

(...where not exists dbo.ContactEvents
.ContactDate < Assignment.StartDate)
