Find the percentage of a student on basis of marks and add percent sign (%) to the result in SQL
Let us first create a table −
mysql> create table DemoTable ( Marks int ); Query OK, 0 rows affected (0.62 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values(88); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable values(65); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable values(98); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable values(45); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable values(67); Query OK, 1 row affected (0.33 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-------+ | Marks | +-------+ | 88 | | 65 | | 98 | | 45 | | 67 | +-------+ 5 rows in set (0.00 sec)
Following is the query to calculate percentage of the student in the basis of marks in 5 subjects. The result would be in percentage; therefore, we will also add percent sign (%) to the calculation −
mysql> select concat(round(SUM(Marks)*100/500),'%') from DemoTable;
This will produce the following output −
+---------------------------------------+ | concat(round(SUM(Marks)*100/500),'%') | +---------------------------------------+ | 73% | +---------------------------------------+ 1 row in set (0.00 sec)
