Question: Can I please have a list of architects who have built at least two bridges, or at least one mill? | What attributes of the architects do you want? | Can you please tell me the names and the ids of the architects who have built two bridges?
SQL: SELECT T1.id ,  T1.name  FROM architect AS T1 JOIN bridge AS T2 ON T1.id   =   T2.architect_id GROUP BY T1.id HAVING count ( * )    =   2
