Dear all,

I have an application that updates all the contacts belonging to a
group, I currently do the following :
-> Get the group id
-> Get all the contacts id inside this group
-> For each of them I am doing an update on the contact => This is
really heavy and seems to take time in real phones while I expect it
to be "instantaneous".

I am wondering if we can, in the ContentResolver.update() method
specify a kind of join.
For instance I'd like to do something like :
UPDATE <people> SET <people.name>="<new name>" FROM People p,
GroupsMemberships gm WHERE p.person_id=gm.person_id and
gm.group_id=<my_group_id>

Does anyone know if it's possible or not?

The update method has got a "where" attribut but can we use this
attribut for complexe requests ?
*****
where   A filter to apply to rows before deleting, formatted as an SQL
WHERE clause (excluding the WHERE itself).

Thanks to everyone for its feedback.
