理解问题SELECT date_format(NOW(), '%Y-%m-%d') as days, DATE_ADD(date_format( NOW(), '%Y-%m-%d' ), INTERVAL - 1 DAY) as days, DATE_ADD(date_format( NOW(), '%Y-%m-%d' ), INTERVAL - 2 DAY) as days 更改为列形式
已完成理解「SELECT date_format(NOW(), '%Y-%m-%d') as days, DATE_ADD(date_format( NOW(), '%Y-%m-%d' ), INTERVAL - 1 DAY) as days, DATE_ADD(date_format( NOW(), '%Y-%m-%d' ), INTERVAL - 2 DAY) as days 更改为列形式」
