Hi Friends,
Please help me out in tuning the query of the below format...
insert into table_x
sel distinct a.loc_cd
a.num as num1
b.num as num2
from table_x a,
table_x b
where a.loc_cd = a.loc_cd
and a.num
The target table has PI (loc_cd,num1,num2) and the source table has the PI (loc_cd,num). The above query has problem of Skewness.
Thanks a lot in advance...
