MySQL日期比较以获取给定范围之间的日期？
让我们首先创建一个表-
mysql> create table DemoTable ( AdmissionDate date );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('2019-08-31');
mysql> insert into DemoTable values('2019-09-01');
mysql> insert into DemoTable values('2019-05-10');
mysql> insert into DemoTable values('2019-06-12');使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
这将产生以下输出-
+---------------+ | AdmissionDate | +---------------+ | 2019-08-31 | | 2019-09-01 | | 2019-05-10 | | 2019-06-12 | +---------------+ 4 rows in set (0.00 sec)
以下是执行日期比较以获取给定范围之间的日期的查询-
mysql> select *from DemoTable where AdmissionDate >='2019-06-01' and AdmissionDate <='2019-08-31';
这将产生以下输出-
+---------------+ | AdmissionDate | +---------------+ | 2019-08-31 | | 2019-06-12 | +---------------+ 2 rows in set (0.00 sec)
