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)
