How to sum cells in a column if a condition is met in another column with MySQL?
For this, you can use the aggregate function SUM() along with the GROUP BY clause. Let us first create a table −
mysql> create table DemoTable -> ( -> EmployeeName varchar(20), -> JoiningDate date, -> Salary int -> ); Query OK, 0 rows affected (0.54 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('David','2019-11-02',400);
Query OK, 1 row affected (0.52 sec)
mysql> insert into DemoTable values('Robert','2018-11-25',100);
Query OK, 1 row affected (0.39 sec)
mysql> insert into DemoTable values('Bob','2019-12-14',600);
Query OK, 1 row affected (0.25 sec)
mysql> insert into DemoTable values('Carol','2019-11-03',300);
Query OK, 1 row affected (0.23 sec)Display all records from the table using select statement −
mysql> select * from DemoTable;
This will produce the following output −
+--------------+-------------+--------+ | EmployeeName | JoiningDate | Salary | +--------------+-------------+--------+ | David | 2019-11-02 | 400 | | Robert | 2018-11-25 | 100 | | Bob | 2019-12-14 | 600 | | Carol | 2019-11-03 | 300 | +--------------+-------------+--------+ 4 rows in set (0.00 sec)
Here is the query to sum cells in a column if a condition is met in another column −
mysql> select year(JoiningDate) as JoiningYear, -> month(JoiningDate) as JoiningMonth, -> sum(Salary) as Total, -> group_concat(EmployeeName) as Name -> from DemoTable -> group by JoiningYear,JoiningMonth;
This will produce the following output −
+-------------+--------------+-------+-------------+ | JoiningYear | JoiningMonth | Total | Name | +-------------+--------------+-------+-------------+ | 2018 | 11 | 100 | Robert | | 2019 | 11 | 700 | David,Carol | | 2019 | 12 | 600 | Bob | +-------------+--------------+-------+-------------+ 3 rows in set (0.04 sec)
