But I don't know why make this decision. Because "where NULL" will get
nothing. And in 0.8.X version, I need to combine multiple condition
according user input to one condition, so my code just like:
cond = None
for c in conditions:
cond = c & cond
So in 0.9.X, the result will be something like: WHERE todo.id = 1 AND NULL,
so I got nothing. Above code is totally wrong in 0.9.X.
And I think maybe the old way makes sence.
