MySQL query to get the highest value from a single row with multiple columns
To get the highest value, use the GREATEST() method. Let us first create a table −
mysql> create table DemoTable -> ( -> Value1 int, -> Value2 int, -> Value3 int -> ); Query OK, 0 rows affected (1.29 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values(100,600,400); Query OK, 1 row affected (0.19 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
+--------+--------+--------+ | Value1 | Value2 | Value3 | +--------+--------+--------+ | 100 | 600 | 400 | +--------+--------+--------+ 1 row in set (0.00 sec)
Following is the query to get the highest value −
mysql> select greatest(Value1,Value2,Value3) AS HighestFrom1Row from DemoTable;
Output
+-----------------+ | HighestFrom1Row | +-----------------+ | 600 | +-----------------+ 1 row in set (0.00 sec)
