Can I Use Numbers as MySQL Column Names?

Using Numbers as MySQL Table Column Names

When creating MySQL tables, it is tempting to use numbers as column names for their convenience. However, this practice can lead to errors when updating the table.

Error with Number Column Names

When attempting to update a table with column names such as "25," you may encounter an error like this:

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>

Restriction on Number Column Names

According to the official MySQL documentation, identifiers, including table and column names, cannot consist solely of digits unless quoted. This restriction ensures syntactic clarity and prevents potential ambiguity with numeric values.

Solution: Quoting with Back Ticks

To use numbers as column names, you must quote them with back ticks (`). For instance, to update the table in the example:

UPDATE table SET `25`='100' WHERE>

By quoting the column name, you differentiate it from numeric values and allow MySQL to correctly parse and execute the query.
