使用select sql语句时，为每个值添加百分比（％）符号

Question

我运行以下选择查询

“选择名称作为名称，将Score1选为Sem1，将Score2选为Sem2，将Score3作为Sem3从表”

此处Score1，Score2，Score3中包含数值。目前我得到的数据如下

Name    Sem1    Sem2    Sem3
Rohit   75      68      92
Rahul   85      79      66
Joy     80      45      81

我需要查询来抛出以下输出。

Name    Sem1    Sem2    Sem3
Rohit   75%     68%     92%
Rahul   85%     79%     66%
Joy     80%     45%     81%

请您为我提供解决方案。

提前致谢..

Answer 1

您需要做的就是：将%字符串连接到指定的字段。

所以，

使用MySQL CONCAT()功能。

"Select Name as Name, CONCAT(Score1, '%') as Sem1, CONCAT(Score2, '%') as Sem2, CONCAT( Score3, '%') as Sem3 from table" 

Answer 2

尝试在mysql中使用CONCAT函数

Select Name as Name, CONCAT(Score1,'%') as Sem1, CONCAT(Score2,'%') as Sem2, CONCAT(Score3,'%') as Sem3 from table

Answer 3

SELECT
    Name AS Name,
    CONCAT(Score1, '%') AS Sem1,
    CONCAT(Score2, '%') AS Sem2,
    CONCAT(Score3, '%') AS Sem3
FROM table

参考：http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_concat

Answer 4

您正在寻找SQL中的CONCAT功能。

Select Name as Name, CONCAT(Score1, '%') as Sem1, CONCAT(Score2 as Sem2, '%'), CONCAT(Score3 as Sem3, '%') from table;

Answer 5

你可以为sql-query的结果添加一个后缀，如下所示：

SELECT Name AS Name, Score1 & " %" AS Sem1, Score2 & " %" AS Sem2, Score3 & " %" AS Sem3 FROM table

我希望这有帮助！

Answer 6

使用CONCAT

Select Name as Name, CONCAT(Score1,'%') as Sem1, CONCAT(Score2,'%') as Sem2, CONCAT(Score3,'%') as Sem3 from table
