解决办法

使用toDateTime 方法对时间进行转换

toDateTime(time, 'Asia/Shanghai')，转成东八区的时间

sql 复制代码

SELECT count(1) from uTableName u WHERE toDateTime(time, 'Asia/Shanghai') > '2024-01-31 00:00:00';
DELETE from uTableName WHERE toDateTime(time, 'Asia/Shanghai') > '2024-01-31 00:00:00';

SELECT count(1) from cTableName c  WHERE toDateTime(time, 'Asia/Shanghai') > '2024-01-31 00:00:00';
DELETE from cTableName WHERE toDateTime(time, 'Asia/Shanghai') > '2024-01-31 00:00:00';
