表关联更新:
UPDATE user_bank a INNER JOIN bank AS b ON a.bank_code = b.bank_code SET a.bank_type =b.id WHERE a.bank_type IS NULL AND a.id=1650;
更新前的查询:
select * from user_bank where id = 1650; select * from user_bank where bank_type is null; select count(*) from user_bank where bank_type is null; select * from bank; select * from bank where bank_code = ‘03010000‘;
