Question

我想做的事情：

选择date = 2012-10-14的行，然后显示该行之后的4行。所以从这个列表中

2012-10-12 column #2
2012-10-13 column #2
2012-10-14 was very sunny.
2012-10-15 rained all day.
2012-10-16 whatever.
2012-10-17 column #2
2012-10-18 column #2
2012-10-19 rained all day.
2012-10-20 whatever.
2012-10-21 column #2
2012-10-22 column #2

它会返回：

2012-10-14 was very sunny.
2012-10-15 rained all day.
2012-10-16 whatever.
2012-10-17 column #2
2012-10-18 column #2

感谢您的帮助。

PS：在数据库中，周末没有数据，所以有些日期会丢失。

Answer 1

SELECT * FROM my_table WHERE date >= '2012-10-14' ORDER BY date LIMIT 5

在sqlfiddle上查看。

Answer 2

此版本适用于日期范围，而不是固定数量的行。目前还不完全清楚你想要哪一个。

select * from mytable where date_diff(date,'2012-10-14') <= 4 and date >= '2012-10-14';

Mysql，根据日期选择行
