Hello,

I currently am using raw sql to make an atomic operation of the following :

UPDATE table SET field1 = 0, flag = 'A' WHERE flag = 'I'

Reading the documentation I realized I could do this:

Table.objects.filter(flag='I').update(field1=0,flag='A')

I want to make sure that this is a unique operation. (to avoid problems of
parallelism and concurrency)

Someone could confirm me this? Apparently the limitations imposed by the
documentation already gives a hint that is a single query but I want to be
sure.
