Similar Output

Question

Hi ,
I have posted the same question earlier but the query had few discrepencies(I had used the query from teradata where syntax is slightly different) .Hence posting the queries again.Mentioned below are 2 queries for which the output are not same.Would really appreciate if some one can help me in modifying the query to generate the same output.
Reason for changing query 1 is because it at times take 7-8 hours to run where as the query 2 is taking less than 20 seconds(because of different reasons like the indexes & no of records etc)
