How Can I Update MySQL Tables with Numeric Column Names?

Using Numbers as Column Names in MySQL Tables

When attempting to update a MySQL table with column names composed solely of numbers, users often encounter syntax errors. This occurs despite attempts to quote or backtick the column names. The error message typically indicates an incorrect SQL syntax.

The underlying reason is that MySQL identifiers, including column names, cannot consist solely of digits. While they can begin with a digit, they must be quoted using backticks if they contain any other digits. This means that column names like "25," "50," and "100" are not valid.

To resolve this issue, users must enclose such column names within backticks. For instance, to update a table with column names "25," "50," and "100," the following query can be used:

UPDATE table SET `25`='100', `50`='200', `100`='300' WHERE>

This approach ensures that the MySQL parser correctly interprets the column names as identifiers rather than numeric values. By following this convention, users can avoid syntax errors and successfully update their tables.
