(1)adddate() addtime()函数 增加天数:set date=adddate(date,10) 增加10天 增加小时数:set date=addtime(date,'1:00:00.00') 推迟一个小时 (其中date为存储日期的列) (2)convert_tz(datetime,time_zone,time_zone) 该函数把第一个时区的日期时间转换为第二个时区的日期时间。要实现这个功能,需要在mysq...

在MySQL 中,可以使用 CAST() 函数或者 STR_TO_DATE() 函数来实现 datetime 与 date 之间的转换。 将datetime 转换成 date: SELECT CAST(datetime_column AS DATE) AS date_column FROM table_name; 复制代码 将date 转换成 datetime: SELECT CAST(date_column AS DATETIME) AS datetime_column FROM table_...
SELECT CONVERT(DATE, SELECT STR_TO_DATE((select date_and_time_text FROM all_dates_and_time),'yyyy-mm-dd hh:mi:ss(24h)')), SELECT CONVERT(TIME, SELECT STR_TO_DATE((select date_and_time_text FROM all_dates_and_time),'yyyy-mm-dd hh:mi:ss(24h)')); ...

MySQL中的DATETIME和DATE是两种日期时间数据类型。DATETIME类型用于存储日期和时间,格式为'YYYY-MM-DD HH:MM:SS',范围从'1000-01-01 00:00:00'到'9999-12-31 23:59:59'。而DATE类型仅用于存储日期,格式为'YYYY-MM-DD',范围从'1000-01-01'到'9999-12-31'。

1、date date仅包含日期,mysql存储和显示的格式是'YYYY-MM-DD',可以表示的范围是'1000-01-01' to '9999-12-31' 2、datetime datetime包含日期、时间两部分,mysql存储和显示的格式是'YYYY-MM-DD hh:mm:ss',可以表示的范围是'1000-01-01 00:00:00' to '9999-12-31 23:59:59' ...
2. date存储范围介于 1000-01-01 到 9999-12-31之间 3. 对应Java类型: java.util.Date(可通过@JsonFormat指定特定格式), 或者 jdk8的LocalDate 一般存储日期格式的字段(如: 生日), 建议使用date 五. int / bigint 有人存时间戳,存一个 int(11) 类型的数值(或者bigint(19)类型数值, 可精确到毫秒),...
