在 MySQL 中从日期记录中搜索日期的最快方法
mysqlmysqli database
最快、最简单的方法是使用 MySQL BETWEEN 关键字。让我们首先创建一个 −
mysql> create table DemoTable1413 -> ( -> EmployeeName varchar(20), -> EmployeeJoiningDate datetime -> ); Query OK, 0 rows affected (0.45 sec)
使用 insert 在表中插入一些记录 −
mysql> insert into DemoTable1413 values('Chris','2018-09-28 11 :10 :50');
Query OK, 1 row affected (0.08 sec)
mysql> insert into DemoTable1413 values('David','2019-09-28 11:10:50');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable1413 values('Mike','2019-09-29 12:40:00');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable1413 values('Carol','2019-09-28 12:06:10');
Query OK, 1 row affected (0.08 sec)
使用 select 语句显示表中的所有记录 −
mysql> select * from DemoTable1413;
这将产生以下输出 −
+--------------+---------------------+ | EmployeeName | EmployeeJoiningDate | +--------------+---------------------+ | Chris | 2018-09-28 11:10:50 | | David | 2019-09-28 11:10:50 | | Mike | 2019-09-29 12:40:00 | | Carol | 2019-09-28 12:06:10 | +--------------+---------------------+ 4 rows in set (0.00 sec)
这是搜索日期之间的日期记录的查询 −
mysql> select * from DemoTable1413 -> where EmployeeJoiningDate between '2019-09-28' and '2019-09-28 23:59:59' -> limit 1;
这将产生以下输出 −
+--------------+---------------------+ | EmployeeName | EmployeeJoiningDate | +--------------+---------------------+ | David | 2019-09-28 11:10:50 | +--------------+---------------------+ 1 row in set (0.03 sec)
