Write the query to transpose rows into columns.

select

emp_id,

max(decode(row_id,0,address))as address1,

max(decode(row_id,1,address)) as address2,

max(decode(row_id,2,address)) as address3

from (select emp_id,address,mod(rownum,3) row_id from temp order by emp_id )

group by emp_id

Other query:

select

emp_id,

max(decode(rank_id,1,address)) as add1,

max(decode(rank_id,2,address)) as add2,

max(decode(rank_id,3,address))as add3

from

(select emp_id,address,rank() over (partition by emp_id order by emp_id,address )rank_id from temp )

group by

emp_id
