Set custom messages on the basis of a column with student marks in MySQL
For this, use CASE statement. Let us first create a table −
mysql> create table DemoTable1952 ( Marks int ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1952 values(35); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1952 values(65); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1952 values(55); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1952 values(39); Query OK, 1 row affected (0.00 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1952;
This will produce the following output −
+-------+ | Marks | +-------+ | 35 | | 65 | | 55 | | 39 | +-------+ 4 rows in set (0.00 sec)
Here is the query to set custom messages on the basis of student marks:
mysql> select case when Marks > 40 then 'Good Marks' else 'Not Good Marks' end as Result from DemoTable1952;
This will produce the following output −
+----------------+ | Result | +----------------+ | Not Good Marks | | Good Marks | | Good Marks | | Not Good Marks | +----------------+ 4 rows in set (0.00 sec)
