Since the column value ‘ADD’ is already a reserved word, therefore you need to use backticks around the word ADD like `ADD`.
Let us see an example and create a table −
mysql> create table DemoTable779 ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, `ADD` int ); Query OK, 0 rows affected (0.47 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable779(`ADD`) values(54); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable779(`ADD`) values(89); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable779(`ADD`) values(66); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable779(`ADD`) values(58); Query OK, 1 row affected (0.10 sec)
Now you can display all records from the table using select statement −
mysql> select *from DemoTable779;
This will produce the following output -
+----+------+ | Id | ADD | +----+------+ | 1 | 54 | | 2 | 89 | | 3 | 66 | | 4 | 58 | +----+------+ 4 rows in set (0.00 sec)
Following is how you can increment the column ‘ADD’ −
mysql> update DemoTable779 set `ADD`=`ADD`+10; Query OK, 4 rows affected (0.20 sec) Rows matched: 4 Changed: 4 Warnings: 0
Let us check table records once again −
mysql> select *from DemoTable779;
This will produce the following output -
+----+------+ | Id | ADD | +----+------+ | 1 | 64 | | 2 | 99 | | 3 | 76 | | 4 | 68 | +----+------+ 4 rows in set (0.00 sec)
