Syntax error Select maximum of sum of two columns in MySQL

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)
