我想选择带日期的记录

我用

SELECT * FROM transactions WHERE date='2016-02-18';

我也在2个日期和我之间选择

SELECT * FROM transactions WHERE date<'2016-02-18' AND date>'2016-02-01';

但它不起作用。（我使用php Mysql xampp）你能帮我理解这些概念吗？

Answer 1

对于ist查询，您需要使用DATE()函数，因为您的列类型为DATETIME或TIMESTAMP，因此您可以将其处理为：

SELECT * FROM transactions WHERE DATE(date) = '2016-02-18';

对于第二个查询，您只需将TIME添加为：

SELECT * FROM transactions WHERE date > '2016-02-01 00:00:00' AND date < '2016-02-18 23:59:59';

Answer 2

是mysql DB吗？

如果不是使用DATE功能：

SELECT * FROM transactions WHERE DATE(date)='2016-02-18';

OR

SELECT * FROM transactions WHERE date BETWEEN '2016-02-18' AND '2016-02-01';

Answer 3

使用此

在查询中使用％和like。您将在给定日期获得所有结果

SELECT * FROM transactions WHERE date like '2016-02-18%';

Answer 4

你应该使用BETWEEN ... AND ...

SELECT * FROM transactions WHERE `date` BETWEEN '2016-02-01' AND '2016-02-18';

使用Date选择数据库数据
