Question: Can you list the names of accounts whose checking balance is above the average checking balance, but savings balance is below the average savings balance?
SQL: SELECT T1.name FROM accounts AS T1 JOIN checking AS T2 ON T1.custid   =   T2.custid WHERE T2.balance  >   ( SELECT avg ( balance )  FROM checking )  INTERSECT SELECT T1.name FROM accounts AS T1 JOIN savings AS T2 ON T1.custid   =   T2.custid WHERE T2.balance  <   ( SELECT avg ( balance )  FROM savings )
