mysql - Is it necessary to have mysql column names to begin with letters?

Question

Consider the following CREATE TABLE query :

CRAETE TABLE tablename (100 VARCHAR(10), 200 VARCHAR(10));

In this query, 100 and 200 are column names. Is it possible to create tables like this ?

Answer 1

From the manual

Identifiers may begin with a digit but unless quoted may not consist solely of digits.

Answer 2

Yes it is possible but you need to wrap those values with backticks.

CREATE TABLE tablename 
(
`100` VARCHAR(10), 
`200` VARCHAR(10)
);
