我有一个MySQL表。什么是sql语句看起来要添加说2天到表中的当前日期值？

UPDATE classes 
SET 
date = date + 1
where id = 161

this adds one second to the value, i don't want to update the time, i want to add two days?

这增加了一秒的值，我不想更新时间，我想添加两天？

Assuming your field is a date type (or similar):

假设您的字段是日期类型（或类似）：

SELECT DATE_ADD(`your_field_name`, INTERVAL 2 DAY) 
FROM `table_name`;

With the example you've provided it could look like this:

您提供的示例可能如下所示：

UPDATE classes 
SET `date` = DATE_ADD(`date` , INTERVAL 2 DAY)
WHERE `id` = 161;

This approach works with datetime , too.

这种方法也适用于datetime。

#2

UPDATE table SET nameofdatefield = ADDDATE(nameofdatefield, 2) WHERE ...

#3

This query stands good for fetching the values between current date and its next 3 dates

此查询适用于获取当前日期与其后3个日期之间的值

SELECT * FROM tableName
WHERE columName BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 3 DAY)

This will eventually add extra 3 days of buffer to the current date.

这最终将为当前日期添加额外3天的缓冲区。

#4

update tablename set coldate=DATE_ADD(coldate, INTERVAL 2 DAY)

#5

SELECT DATE_ADD(CURDATE(), INTERVAL 2 DAY)

#6

For your need:

根据您的需要：

UPDATE classes 
SET `date` = DATE_ADD(`date`, INTERVAL 2 DAY)
WHERE id = 161

#7

 DATE_ADD(FROM_DATE_HERE, INTERVAL INTERVAL_TIME_HERE DAY)

will give the Date after adjusting the INTERVAL

调整INTERVAL后会给出日期

eg.

例如。

DATE_ADD(NOW(), INTERVAL -1 DAY) for deducting 1 DAY from current Day
DATE_ADD(NOW(), INTERVAL 2 DAY)  for adding 2 Days

You can use like

你可以使用喜欢

UPDATE classes WHERE date=(DATE_ADD(date, INTERVAL 1 DAY)) WHERE id=161

SET date = DATE_ADD( fieldname, INTERVAL 2 DAY )
