---------------------------------------
@[~julianhyde] Thanks for your review，Are you considering the following
situations?
1.
{code:java}
select tableA.C+1 as A_C,tableB.C+1 as B_C
from tableA,tableB
group by A_C,B_C
{code}
A_C will still replace to tableA.C+1，like this
{code:java}
select tableA.C as A_C,tableB.C as B_C
from tableA,tableB
group by tableA.C,tableB.C
{code}
because only when tableA.C same with A_C in"tableA.C+1 as A_C" will not replace
2.
{code:java}
select tableA.C+1 as A_C,tableB.C+1 as B_C
from tableA,tableB
group by tableA.C+1,tableB.C+1
{code}
it need not replace.
3.
{code:java}
select tableA.C+tableB.C as C
from tableA,tableB
group by C
{code}
C will still replace to tableA.C+tableB.C, like this
{code:java}
select tableA.C+tableB.C as C
from tableA,tableB
group by tableA.C+tableB.C
{code}
