Update two columns with a single MySQL query
For this, you need to use SET command only once. Let us first create a table −
mysql> create table DemoTable1909 ( Id int NOT NULL, FirstName varchar(20), LastName varchar(20) ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1909 values(101,'John','Smith'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1909 values(102,'John','Doe'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1909 values(103,'Adam','Smith'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1909 values(104,'David','Miller'); Query OK, 1 row affected (0.00 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1909;
This will produce the following output −
+-----+-----------+----------+ | Id | FirstName | LastName | +-----+-----------+----------+ | 101 | John | Smith | | 102 | John | Doe | | 103 | Adam | Smith | | 104 | David | Miller | +-----+-----------+----------+ 4 rows in set (0.00 sec)
Here is the query to update two column values −
mysql> update DemoTable1909 set FirstName='Carol',LastName='Taylor' where Id=103; Query OK, 1 row affected (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 0
Let us check the table records once again −
mysql> select * from DemoTable1909;
This will produce the following output −
+-----+-----------+----------+ | Id | FirstName | LastName | +-----+-----------+----------+ | 101 | John | Smith | | 102 | John | Doe | | 103 | Carol | Taylor | | 104 | David | Miller | +-----+-----------+----------+ 4 rows in set (0.00 sec)
