How Can I Use Numbers as Column Names in MySQL Tables?

Using Numbers as MySQL Table Column Names

In MySQL, attempting to update a table with a column name solely consisting of digits, such as '25' or '100', often results in an SQL syntax error. This error occurs because identifiers in MySQL cannot start with a digit unless quoted explicitly.

To use a number as a table column name, it must be enclosed within backticks (`) to identify it as an explicitly named entity. For example, to update a column named '25':

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

By enclosing the column name in backticks, MySQL recognizes it as a quoted identifier and updates the table successfully. This ensures that the column name is treated as a string rather than an integer, preventing the syntax error.
