How to delete fields with values more than a particular value in MySQL?

Let us first create a table −

mysql> create table DemoTable
(
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   PlayerName varchar(100),
   PlayerScore int
);
Query OK, 0 rows affected (0.97 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable(PlayerName,PlayerScore) values('Chris',780);
Query OK, 1 row affected (0.25 sec)
mysql> insert into DemoTable(PlayerName,PlayerScore) values('Sam',1100);
Query OK, 1 row affected (0.23 sec)
mysql> insert into DemoTable(PlayerName,PlayerScore) values('Mike',900);
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable(PlayerName,PlayerScore) values('Bob',890);
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable(PlayerName,PlayerScore) values('Carol',1000);
Query OK, 1 row affected (0.20 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+----+------------+-------------+
| Id | PlayerName | PlayerScore |
+----+------------+-------------+
|  1 | Chris      |         780 |
|  2 | Sam        |        1100 |
|  3 | Mike       |         900 |
|  4 | Bob        |         890 |
|  5 | Carol      |        1000 |
+----+------------+-------------+
5 rows in set (0.00 sec)

Following is the query to delete fields with values more than a particular value in MySQL −

mysql> delete from DemoTable where PlayerScore > 900;
Query OK, 2 rows affected (0.18 sec)

Let us check the table records once again.

mysql> select *from DemoTable;

This will produce the following output −

+----+------------+-------------+
| Id | PlayerName | PlayerScore |
+----+------------+-------------+
|  1 | Chris      |         780 |
|  3 | Mike       |         900 |
|  4 | Bob        |         890 |
+----+------------+-------------+
3 rows in set (0.00 sec)
