Add a percentage (%) sign at the end to each value while using MySQL SELECT statement
To add percentage sign at the end, use CONCAT() function. Let us first create a table −
mysql> create table DemoTable
(
StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
StudentName varchar(100),
StudentScore int
);
Query OK, 0 rows affected (0.68 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(StudentName,StudentScore) values('John',65);
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable(StudentName,StudentScore) values('Chris',98);
Query OK, 1 row affected (0.30 sec)
mysql> insert into DemoTable(StudentName,StudentScore) values('Robert',91);
Query OK, 1 row affected (0.09 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-----------+-------------+--------------+
| StudentId | StudentName | StudentScore |
+-----------+-------------+--------------+
| 1 | John | 65 |
| 2 | Chris | 98 |
| 3 | Robert | 91 |
+-----------+-------------+--------------+
3 rows in set (0.00 sec)
Following is the query to add a percentage (%) sign to each value at the end while using MySQL SELECT statement −
mysql> select StudentId,StudentName,concat(StudentScore,'%') AS StudentScore from DemoTable;
This will produce the following output −
+-----------+-------------+--------------+
| StudentId | StudentName | StudentScore |
+-----------+-------------+--------------+
| 1 | John | 65% |
| 2 | Chris | 98% |
| 3 | Robert | 91% |
+-----------+-------------+--------------+
3 rows in set (0.00 sec)
