What is the MySQL syntax error in this query – Creating a table with reserved keyword?
Let’s say we tried creating a table with name “groups”, which is a reserved keyword in MySQL You cannot use “groups” because groups is a reserved keyword in MySQL.
Following error occurred while creating a table with name “groups” −
mysql> create table groups −> ( −> id int, −> name varchar(40) −> ); ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'groups ( id int, name varchar(40) )' at line 1
In order to create a table with reserved keyword, you need to use the concept of backticks(``).
Let us create a table −
mysql> create table `groups` -> ( −> id int, −> name varchar(40) −> ) −> ; Query OK, 0 rows affected (3.08 sec)
Insert some records into the table with the help of insert command −
mysql> insert into `groups` values(10,'John'); Query OK, 1 row affected (0.30 sec) mysql> insert into `groups` values(11,'Bob'); Query OK, 1 row affected (0.32 sec) mysql> insert into `groups` values(12,'Mike'); Query OK, 1 row affected (0.40 sec)
Display records from the table using select statement
mysql> select *from `groups`;
This will produce the following output −
+------+------+ | id | name | +------+------+ | 10 | John | | 11 | Bob | | 12 | Mike | +------+------+ 3 rows in set (0.04 sec)
