Complicated query

I have two tables Trade table and Cons table. Records are inserted in both the tables independent of each other. There are fields like Exc_Ref, Qty, Date in both the tables.

I need to write a query which should give me records :

  1. Where there is missing Exc_Ref value in either of the table. i.e. If Trade table has a Exc_Ref value but missing in Cons table then that record should be displayed. Similarly if Cons has a Exc_Ref value which is not found in Trade table then that too should be displayed.
  2. In case where both the tables have matching Exc_Ref data then it should display the record only when the remaining column does not match like Qty or Date.

Please help me to resolve this complicated query.
