Hi balaji,
V can use a temperory flag in order to change y--n and n--y. but it will take three queries. as like swapping v can do ie., y--a and n--y finally a--n. like that.

Update empsaltable a
set a.flag =
(Select (case
when (b.flag = 'y') then (n)
else (y)
end) b.flag
from empsaltable b where a.name = b.name);

Please Correct me...!
