this solution is based on the assumption that there cannot be an entry in the table 
with startdate null and valid end date..ie there cannot be an entry with code=N 
without a corresponding code=R The following query will generate the result set you 
desire   Select a.id, a.dates AS startdate,b.dates as enddate,a.code,b.code from 
(select * from table-A where code='R') a  left join  (select * from table-B where 
code='N') b on  a.id=b.id
