Translate the following question to SQL: Find the total checking and saving balance of all accounts sorted by the total balance in ascending order.

Schema: CREATE TABLE ACCOUNTS (
    custid BIGINT NOT NULL  PRIMARY KEY,
    name VARCHAR(64) NOT NULL,
    UNIQUE (custid)
);

CREATE TABLE SAVINGS (
    custid BIGINT NOT NULL  PRIMARY KEY,
    balance FLOAT NOT NULL,
    UNIQUE (custid),
    FOREIGN KEY (custid) REFERENCES ACCOUNTS(custid)
);

CREATE TABLE CHECKING (
    custid BIGINT NOT NULL  PRIMARY KEY,
    balance FLOAT NOT NULL,
    UNIQUE (custid),
    FOREIGN KEY (custid) REFERENCES ACCOUNTS(custid),
    CREATE TABLE CHECKING (
);
user
SELECT T1.balance + T2.balance FROM checking AS T1 JOIN savings AS T2 ON T1.custid  =  T2.custid ORDER BY T1.balance + T2.balance
