您可以使用 MySQL 中的 MONTHNAME() 函数根据数字显示月份名称。语法如下。
SELECT MONTHNAME(STR_TO_DATE(yourColumnName,’%m’)) as anyVariableName from yourTableName;
为了理解上述概念，让我们首先创建一个表。创建表的查询如下。
mysql> create table MonthDemo -> ( -> MonthNum int -> ); Query OK, 0 rows affected (0.87 sec)
使用 insert 命令在表中插入一些记录。 查询语句如下 −
mysql> insert into MonthDemo values(1); Query OK, 1 row affected (0.14 sec) mysql> insert into MonthDemo values(2); Query OK, 1 row affected (0.15 sec) mysql> insert into MonthDemo values(3); Query OK, 1 row affected (0.12 sec) mysql> insert into MonthDemo values(4); Query OK, 1 row affected (0.12 sec) mysql> insert into MonthDemo values(5); Query OK, 1 row affected (0.13 sec) mysql> insert into MonthDemo values(6); Query OK, 1 row affected (0.18 sec) mysql> insert into MonthDemo values(7); Query OK, 1 row affected (0.13 sec) mysql> insert into MonthDemo values(8); Query OK, 1 row affected (0.13 sec) mysql> insert into MonthDemo values(9); Query OK, 1 row affected (0.15 sec) mysql> insert into MonthDemo values(10); Query OK, 1 row affected (0.13 sec) mysql> insert into MonthDemo values(11); Query OK, 1 row affected (0.14 sec) mysql> insert into MonthDemo values(12); Query OK, 1 row affected (0.15 sec)
使用 select 命令显示表中的所有记录。查询如下
mysql> select *from MonthDemo;
以下是输出。
+------------+ | MonthNum | +------------+ | 1 | | 2 | | 3 | | 4 | | 5 | | 6 | | 7 | | 8 | | 9 | | 10 | | 11 | | 12 | +------------+ 12 rows in set (0.00 sec)
这是显示月份名称的查询。
mysql> select monthname(str_to_date(MonthNum,'%m')) as MonthName from MonthDemo;
以下是输出。
+-----------+ | MonthName | +-----------+ | January | | February | | March | | April | | May | | June | | July | | August | | September | | October | | November | | December | +-----------+ 12 rows in set (0.00 sec)
