从MySQL中的月份编号中获取月份名称?
您可以使用MONTHNAME()
MySQL中的函数从数字显示月份名称。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
-> );
使用insert命令在表中插入一些记录。查询如下-
mysql> insert into MonthDemo values(1);mysql> insert into MonthDemo values(2);
mysql> insert into MonthDemo values(3);
mysql> insert into MonthDemo values(4);
mysql> insert into MonthDemo values(5);
mysql> insert into MonthDemo values(6);
mysql> insert into MonthDemo values(7);
mysql> insert into MonthDemo values(8);
mysql> insert into MonthDemo values(9);
mysql> insert into MonthDemo values(10);
mysql> insert into MonthDemo values(11);
mysql> insert into MonthDemo values(12);
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)
