You cannot create database with numeric name as shown below −
mysql> create database 1233;
This will produce the following output −
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 '1233' at line 1
To create a database with numeric name, you need to use backticks around the database name −
create database yourDatabaseName;
Let us implement the above syntax −
mysql> create database `1233`; Query OK, 1 row affected (0.20 sec)
Now you can switch to the same database −
mysql> use `1233`; Database changed
