Get sum of column with conditions in MySQL

Let us first create a table −

mysql> create table DemoTable1489    -> (    -> ProductId int,    -> ProductPrice int    -> ); Query OK, 0 rows affected (0.49 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1489 values(100,900); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable1489 values(115,1000); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable1489 values(119,2100); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable1489 values(125,2100); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable1489 values(128,2900); Query OK, 1 row affected (0.25 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1489;

This will produce the following output −

+-----------+--------------+ | ProductId | ProductPrice | +-----------+--------------+ |       100 |          900 | |       115 |         1000 | |       119 |         2100 | |       125 |         2100 | |       128 |         2900 | +-----------+--------------+ 5 rows in set (0.00 sec)

Here is the query to get sum of columns with conditions −

mysql> select ProductId div 10,sum(ProductPrice) from DemoTable1489    -> group by ProductId div 10;

This will produce the following output −

+------------------+-------------------+ | ProductId div 10 | sum(ProductPrice) | +------------------+-------------------+ |               10 |               900 | |               11 |              3100 | |               12 |              5000 | +------------------+-------------------+ 3 rows in set (0.00 sec)
