Getting maximum from a column value and set it for all other values in the same column with MySQL?
Let us first create a table −
mysql> create table DemoTable ( FirstName varchar(100), Score int ); Query OK, 0 rows affected (0.60 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('David',59);
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable values('Chris',97);
Query OK, 1 row affected (0.24 sec)
mysql> insert into DemoTable values('Bob',98);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('Carol',91);
Query OK, 1 row affected (0.11 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-----------+-------+ | FirstName | Score | +-----------+-------+ | David | 59 | | Chris | 97 | | Bob | 98 | | Carol | 91 | +-----------+-------+ 4 rows in set (0.00 sec)
Following is the query to get maximum from a column value and set it for all other values in the same column −
mysql> select FirstName,(select max(Score) from DemoTable) as Score from DemoTable;
This will produce the following output −
+-----------+-------+ | FirstName | Score | +-----------+-------+ | David | 98 | | Chris | 98 | | Bob | 98 | | Carol | 98 | +-----------+-------+ 4 rows in set (0.00 sec)
