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

Question

I have a table that has column names like 25, 50, 100, etc..

When trying to update the table I get an error, no matter how I do it

UPDATE table SET '25'='100' WHERE id = '1'

I have tried quoting and backticking every which way but without success.

The error is always along the lines of:

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 ''25'=100 WHERE id=1' at line 1

If I change the column name to twentyfive - I don't have a problem, but that's not what I want. Is it possible to use a number as a column name?

Answer 1

From the docs:

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

Which means you must quote it with back ticks like `25`:

UPDATE table SET `25`='100' WHERE id='1'
