How to update multiple rows using single WHERE clause in MySQL?
For this, you can use MySQL IN(). Let us first create a −
mysql> create table DemoTable1420 -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> FirstName varchar(20), -> LastName varchar(20), -> Age int -> ); Query OK, 0 rows affected (1.12 sec)
Insert some records in the table using insert −
mysql> insert into DemoTable1420(FirstName,LastName,Age) values('Chris','Brown',23);
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable1420(FirstName,LastName,Age) values('David','Miller',22);
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable1420(FirstName,LastName,Age) values('John','Smith',24);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable1420(FirstName,LastName,Age) values('John','Doe',21);
Query OK, 1 row affected (0.43 sec)
mysql> insert into DemoTable1420(FirstName,LastName,Age) values('Adam','Smith',25);
Query OK, 1 row affected (0.18 sec)Display all records from the table using select −
mysql> select * from DemoTable1420;
This will produce the following output −
+----+-----------+----------+------+ | Id | FirstName | LastName | Age | +----+-----------+----------+------+ | 1 | Chris | Brown | 23 | | 2 | David | Miller | 22 | | 3 | John | Smith | 24 | | 4 | John | Doe | 21 | | 5 | Adam | Smith | 25 | +----+-----------+----------+------+ 5 rows in set (0.00 sec)
Following is the query to update multiple rows using single where clause −
mysql> update DemoTable1420 -> set FirstName='Carol',LastName='Taylor' -> where Id IN(1,3,4,5); Query OK, 4 rows affected (0.42 sec) Rows matched: 4 Changed: 4 Warnings: 0
Let us check the table records once again −
mysql> select * from DemoTable1420;
This will produce the following output −
+----+-----------+----------+------+ | Id | FirstName | LastName | Age | +----+-----------+----------+------+ | 1 | Carol | Taylor | 23 | | 2 | David | Miller | 22 | | 3 | Carol | Taylor | 24 | | 4 | Carol | Taylor | 21 | | 5 | Carol | Taylor | 25 | +----+-----------+----------+------+ 5 rows in set (0.00 sec)
