从 MySQL NOW() -1 天中选择记录?


要获取 NOW()-1 天的记录,可以使用以下语法 -

select *from yourTableName where yourColumnName >=now()-interval 1 day;

要了解上述语法,让我们首先创建一个表。创建表的查询。

mysql> create table GetRecordsFromNow
   −> (
   −> YourDateTime datetime
   −> );
Query OK, 0 rows affected (1.76 sec)

现在将一些日期插入字段。插入记录的查询如下 -

mysql> insert into GetRecordsFromNow values(date_add(now(),interval 3 day));
Query OK, 1 row affected (0.28 sec)

mysql> insert into GetRecordsFromNow values(date_add(now(),interval -1 day));
Query OK, 1 row affected (0.11 sec)

mysql> insert into GetRecordsFromNow values(date_add(now(),interval -2 day));
Query OK, 1 row affected (0.14 sec)

mysql> insert into GetRecordsFromNow values(date_add(now(),interval -3 day));
Query OK, 1 row affected (0.09 sec)

mysql> insert into GetRecordsFromNow values(date_add(now(),interval -1 day));
Query OK, 1 row affected (0.08 sec)

在 select 语句的帮助下显示所有记录。查询如下 -

mysql> select *from GetRecordsFromNow;

以下是输出 -

+---------------------+
| YourDateTime        |
+---------------------+
| 2018-12-07 22:30:18 |
| 2018-12-03 22:30:31 |
| 2018-12-02 22:30:41 |
| 2018-12-01 22:30:56 |
| 2018-12-03 22:31:04 |
+---------------------+
5 rows in set (0.00 sec)

以下是显示现在() -1 天记录的查询 -

mysql> select *from GetRecordsFromNow where YourDateTime >= now()-interval 1 day;

以下是输出 -

+---------------------+
| YourDateTime        |
+---------------------+
| 2018-12-07 22:30:18 |
+---------------------+
1 row in set (0.04 sec)
