在 MySQL 中将分钟数 INT 转换为 TIME?
mysqlmysqli database
要在 MySQL 中将分钟数 INT 转换为 TIME，您可以使用 SEC_TO_TIME() 函数。
语法如下
select SEC_TO_TIME(yourIntColumnName*60) AS `anyAliasName` from yourTableName;
为了理解上述语法，让我们创建一个表。创建表的查询如下
mysql> create table convertNumberToMinute -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> NumberToMinute int -> ); Query OK, 0 rows affected (0.79 sec)
使用 insert 命令在表中插入一些记录。
查询如下
mysql> insert into convertNumberToMinute(NumberToMinute) values(60); Query OK, 1 row affected (0.12 sec) mysql> insert into convertNumberToMinute(NumberToMinute) values(70); Query OK, 1 row affected (0.21 sec) mysql> insert into convertNumberToMinute(NumberToMinute) values(80); Query OK, 1 row affected (0.15 sec) mysql> insert into convertNumberToMinute(NumberToMinute) values(90); Query OK, 1 row affected (0.13 sec) mysql> insert into convertNumberToMinute(NumberToMinute) values(100); Query OK, 1 row affected (0.22 sec) mysql> insert into convertNumberToMinute(NumberToMinute) values(110); Query OK, 1 row affected (0.07 sec) mysql> insert into convertNumberToMinute(NumberToMinute) values(120); Query OK, 1 row affected (0.15 sec)
使用 select 语句显示表中的所有记录。
查询如下
mysql> select *from convertNumberToMinute;
以下是输出 −
+----+----------------+ | Id | NumberToMinute | +----+----------------+ | 1 | 60 | | 2 | 70 | | 3 | 80 | | 4 | 90 | | 5 | 100 | | 6 | 110 | | 7 | 120 | +----+----------------+ 7 rows in set (0.00 sec)
这是在 MySQL 中将分钟数 INT 转换为 TIME 的查询
mysql> select SEC_TO_TIME(NumberToMinute*60) AS `MinuteDemo` from convertNumberToMinute;
以下是输出 −
+------------+ | MinuteDemo | +------------+ | 01:00:00 | | 01:10:00 | | 01:20:00 | | 01:30:00 | | 01:40:00 | | 01:50:00 | | 02:00:00 | +------------+ 7 rows in set (0.00 sec)
这是显示‘NumberToMinute’列的查询
mysql> select NumberToMinute, SEC_TO_TIME(NumberToMinute*60) AS `MinuteDemo` from convertNumberToMinute;
以下是输出 −
+----------------+------------+ | NumberToMinute | MinuteDemo | +----------------+------------+ | 60 | 01:00:00 | | 70 | 01:10:00 | | 80 | 01:20:00 | | 90 | 01:30:00 | | 100 | 01:40:00 | | 110 | 01:50:00 | | 120 | 02:00:00 | +----------------+------------+ 7 rows in set (0.00 sec)
