I have to the following case statement that calculates count and sum respectively:

if colA='e' or (cola='f' and colb<>0) and date=2012
then set xy=1
else set xy= o

if colA='e' or (cola='f' and colb<>0) and date=2012
then sum y
else o

here, I am joining 3 tables.

just translate it to case ...when


..
case when colA='e' or (cola='f' and colb<>0) and date=2012
then 1
else 0
end as xy,
case when colA='e' or (cola='f' and colb<>0) and date=2012
then sum(y)
else 0
end as  othercol
..
