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)
