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)
