Can we select field name in MySQL that contains an asterisk?
No, we cannot. To still work it out, use backticks around the field name. Let us first create a table with column name with asterisk, `Name*` −
mysql> create table DemoTable -> ( -> `Name*` varchar(20) -> ); Query OK, 0 rows affected (2.03 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(`Name*`) values('Chris Brown');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable(`Name*`) values('David Miller');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable(`Name*`) values('John Doe');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable(`Name*`) values('John Smith');
Query OK, 1 row affected (0.23 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+--------------+ | Name* | +--------------+ | Chris Brown | | David Miller | | John Doe | | John Smith | +--------------+ 4 rows in set (0.00 sec)
Following is the query to select field name which contains an asterisk −
mysql> select `Name*` from DemoTable;
This will produce the following output −
+--------------+ | Name* | +--------------+ | Chris Brown | | David Miller | | John Doe | | John Smith | +--------------+ 4 rows in set (0.00 sec)
