Select maximum of sum of two columns in MySQL
To select maximum of sum of two columns, use aggregate function MAX() along with subquery. Let us first create a table −
mysql> create table DemoTable1587 -> ( -> Value1 int, -> Value2 int -> ); Query OK, 0 rows affected (0.59 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1587 values(30,50); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable1587 values(80,90); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable1587 values(40,67); Query OK, 1 row affected (0.13 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1587;
This will produce the following output −
+--------+--------+ | Value1 | Value2 | +--------+--------+ | 30 | 50 | | 80 | 90 | | 40 | 67 | +--------+--------+ 3 rows in set (0.00 sec)
Here is the query to select maximum of sum of two columns −
mysql> select * from DemoTable1587 -> where Value1+Value2=( select max(Value1+Value2) from DemoTable1587);
This will produce the following output −
+--------+--------+ | Value1 | Value2 | +--------+--------+ | 80 | 90 | +--------+--------+ 1 row in set (0.03 sec)
