Schema: CREATE TABLE checking (custid VARCHAR, balance INTEGER); CREATE TABLE savings (custid VARCHAR, balance INTEGER); CREATE TABLE savings (balance INTEGER); CREATE TABLE checking (balance INTEGER); CREATE TABLE accounts (name VARCHAR, custid VARCHAR)
Question: Find 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)
