Can we use the result of a SUM() function in MySQL WHERE clause
We can use the HAVING clause rather than the WHERE in MySQL. Let us first create a table −
mysql> create table DemoTable ( Name varchar(50), Price int ); Query OK, 0 rows affected (0.79 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Chris',30);
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('David',40);
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('Chris',10);
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable values('Mike',44);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('David',5);
Query OK, 1 row affected (0.17 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-------+-------+ | Name | Price | +-------+-------+ | Chris | 30 | | David | 40 | | Chris | 10 | | Mike | 44 | | David | 5 | +-------+-------+ 5 rows in set (0.00 sec)
Following is the query to use the result of SUM() function in HAVING clause −
mysql> select Name,SUM(Price) AS Total_Price from DemoTable group by Name having Total_Price > 40;
This will produce the following output −
+-------+-------------+ | Name | Total_Price | +-------+-------------+ | David | 45 | | Mike | 44 | +-------+-------------+ 2 rows in set (0.03 sec)
