Update multiple columns of a single row MySQL?
Let us first create a table −
mysql> create table DemoTable -> ( -> FirstName varchar(100), -> Age int, -> Score int -> ); Query OK, 0 rows affected (0.62 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Robert',21,78);
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable values('Bob',20,90);
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable values('Sam',22,69);
Query OK, 1 row affected (0.20 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
+-----------+------+-------+ | FirstName | Age | Score | +-----------+------+-------+ | Robert | 21 | 78 | | Bob | 20 | 90 | | Sam | 22 | 69 | +-----------+------+-------+ 3 rows in set (0.00 sec)
Following is the query to update columns Age and Score for only a row with FirstName “Bob” −
mysql> update DemoTable -> set Age=25, -> Score=Score+9 -> where FirstName='Bob'; Query OK, 1 row affected (0.17 sec) Rows matched: 1 Changed: 1 Warnings: 0
Let us check the table records once again −
mysql> select *from DemoTable;
Output
+-----------+------+-------+ | FirstName | Age | Score | +-----------+------+-------+ | Robert | 21 | 78 | | Bob | 25 | 99 | | Sam | 22 | 69 | +-----------+------+-------+ 3 rows in set (0.00 sec)
