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)
