select
   sta.sga_size                 sga_size_mb,
   sta.sga_size_factor,
   sta.estd_db_time,
   sta.estd_physical_reads,
   sta.estd_buffer_cache_size,
   sta.estd_shared_pool_size,
   sta.con_id
from
   v$sga_target_advice sta;

TODO

Is the value of total_sga_mb and sga_size_1_mb as returned by the following query always equal?
select
   (select round(sum(value)/1024/1024) from v$sga) total_sga_mb,
   (select sga_size from v$sga_target_advice where sga_size_factor = 1) sga_size_1_mb
from
   dual;
