How to update a range of records in MySQL?
To update a range of records in MySQL, you can use BETWEEN. Let us first create a table:
mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, Name varchar(20), Age int ); Query OK, 0 rows affected (0.53 sec)
Following is the query to insert some records in the table using insert command:
mysql> insert into DemoTable(Name,Age) values('Larry',23);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable(Name,Age) values('Sam',24);
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable(Name,Age) values('Chris',21);
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable(Name,Age) values('Carol',25);
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable(Name,Age) values('David',22);
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable(Name,Age) values('Robert',26);
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable(Name,Age) values('John',20);
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable(Name,Age) values('Mike',27);
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable(Name,Age) values('Johnny',28);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable(Name,Age) values('James',23);
Query OK, 1 row affected (0.23 sec)Following is the query to display records from the table using select command:
mysql> select *from DemoTable;
This will produce the following output:
+----+--------+------+ | Id | Name | Age | +----+--------+------+ | 1 | Larry | 23 | | 2 | Sam | 24 | | 3 | Chris | 21 | | 4 | Carol | 25 | | 5 | David | 22 | | 6 | Robert | 26 | | 7 | John | 20 | | 8 | Mike | 27 | | 9 | Johnny | 28 | | 10 | James | 23 | +----+--------+------+ 10 rows in set (0.00 sec)
Following is the query to update a range of records in MySQL. We are updating the Name to ‘Bob’ for Ids in the range 5 to 10:
mysql> update DemoTable set Name='Bob', Age=23 where Id between 5 AND 10; Query OK, 6 rows affected (0.25 sec) Rows matched: 6 Changed: 6 Warnings: 0
Let us now display all records including updated records:
mysql> select *from DemoTable;
This will produce the following output
+----+-------+------+ | Id | Name | Age | +----+-------+------+ | 1 | Larry | 23 | | 2 | Sam | 24 | | 3 | Chris | 21 | | 4 | Carol | 25 | | 5 | Bob | 23 | | 6 | Bob | 23 | | 7 | Bob | 23 | | 8 | Bob | 23 | | 9 | Bob | 23 | | 10 | Bob | 23 | +----+-------+------+ 10 rows in set (0.00 sec)
