What are the ids and names of the web accelerators that are compatible with two or more browsers?
create table accelerator_compatible_browser (accelerator_id varchar, PRIMARY KEY (accelerator_id)); create table web_client_accelerator (id varchar, name varchar, PRIMARY KEY (id))
select t1.id, t1.name from web_client_accelerator as t1 join accelerator_compatible_browser as t2 on t2.accelerator_id = t1.id group by t1.id having count(*) >= 2
