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

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)
