How to ignore specific records and add remaining corresponding records (numbers) in MySQL?

MySQLMySQLi Database

Let us first create a table −

mysql> create table DemoTable
   -> (
   -> Name varchar(20),
   -> Amount int
   -> );
Query OK, 0 rows affected (0.61 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('John',200);
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable values('Chris',150);
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable values('Mike',500);
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('John',350);
Query OK, 1 row affected (0.18 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable;

This will produce the following output −

+-------+--------+
| Name  | Amount |
+-------+--------+
| John  | 200    |
| Chris | 150    |
| Mike  | 500    |
| John  | 350    |
+-------+--------+
4 rows in set (0.00 sec)

Here is the query to ignore specific records and add remaining records (numbers) −

mysql> select sum(Amount) from DemoTable
   -> where Name!='John';

This will produce the following output −

+-------------+
| sum(Amount) |
+-------------+
|         650 |
+-------------+
1 row in set (0.00 sec)
