Can a number be used to name a MySQL table column?

Yes, we can include a number for column name in MySQL. We need to use the symbol backtick, which is as follows

( ` `)

To understand, we will make a table with the help of CREATE command. Let us create a table −

mysql> CREATE table NumberColumnDemo
-> (
-> `123` varchar(100)
-> );
Query OK, 0 rows affected (0.51 sec)

Above, I have created a column name as a number with the help of backtick symbol.

Now, we can check the same by inserting records with the help of INSERT command. Let us insert a record, which is as follows −

mysql> INSERT into NumberColumnDemo values('45678');
Query OK, 1 row affected (0.20 sec)

After that, we can display all the records with the help of SELECT statement. The query is as follows −

mysql> SELECT * from NumberColumnDemo;

The following is the output −

+-------+
| 123   |
+-------+
| 45678 |
+-------+
1 row in set (0.00 sec)
