MySQL query error with a table named “order”?
The order is a reserved word. To still use a reserved word, you need to use backticks around the column name. Let us first create a table −
mysql> create table `order` -> ( -> StudentId int -> ); Query OK, 0 rows affected (1.78 sec)
Insert some records in the table using insert command −
mysql> insert into `order` values(101); Query OK, 1 row affected (0.26 sec) mysql> insert into `order` values(210); Query OK, 1 row affected (0.18 sec) mysql> insert into `order` values(190); Query OK, 1 row affected (0.28 sec) mysql> insert into `order` values(180); Query OK, 1 row affected (0.46 sec) mysql> insert into `order` values(205); Query OK, 1 row affected (0.28 sec)
Display all records from the table using select statement −
mysql> select *from `order`;
This will produce the following output −
+-----------+ | StudentId | +-----------+ | 101 | | 210 | | 190 | | 180 | | 205 | +-----------+ 5 rows in set (0.00 sec)
Here is the query to use ‘order’ as table name using backticks −
mysql> select *from `order` order by StudentId desc limit 1;
This will produce the following output −
+-----------+ | StudentId | +-----------+ | 210 | +-----------+ 1 row in set (0.03 sec)
