格式为 2015-07-01 11:15:30 的 MySQL 按月搜索结果?
为此请使用 MONTH() 和 YEAR()。我们首先创建一个表 -
mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, ShippingDate datetime ); Query OK, 0 rows affected (0.54 sec)
使用 insert 命令在表中插入一些记录 -
mysql> insert into DemoTable(ShippingDate) values('2019-01-21 10:40:21'); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable(ShippingDate) values('2015-07-01 11:15:30'); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable(ShippingDate) values('2012-12-31 10:45:56'); Query OK, 1 row affected (0.14 sec)
使用 select 语句显示表中的所有记录 -
mysql> select *from DemoTable;
将生成以下输出 -
+----+---------------------+ | Id | ShippingDate | +----+---------------------+ | 1 | 2019-01-21 10:40:21 | | 2 | 2015-07-01 10:40:20 | | 3 | 2012-12-31 10:45:56 | +----+---------------------+ 3 rows in set (0.00 sec)
以下是按 MONTH 和 YEAR 搜索结果的查询 -
mysql> select *from DemoTable where MONTH(ShippingDate)=7 and YEAR(ShippingDate)=2015;
将生成以下输出 -
+----+---------------------+ | Id | ShippingDate | +----+---------------------+ | 2 | 2015-07-01 11:15:30 | +----+---------------------+ 1 row in set (0.03 sec)
