从MySQL中的日期记录中搜索日期的最快方法
最快和最简单的方法是使用MySQLBETWEEN关键字。让我们首先创建一个-
mysql> create table DemoTable1413 -> ( -> EmployeeName varchar(20), -> EmployeeJoiningDate datetime -> );
使用insert在表中插入一些记录-
mysql> insert into DemoTable1413 values('Chris','2018-09-28 11 :10 :50');
mysql> insert into DemoTable1413 values('David','2019-09-28 11:10:50');
mysql> insert into DemoTable1413 values('Mike','2019-09-29 12:40:00');
mysql> insert into DemoTable1413 values('Carol','2019-09-28 12:06:10');使用选择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)
