Support for Queries with Column Named null and ON CLUSTER

Why it matters

This feature solves the issue where queries could not correctly handle columns named null, which is a reserved keyword in SQL. Allowing such columns to be referenced properly enables users to work with tables that include a column named null without syntax errors, improving compatibility and flexibility.

How to use it

To use this feature, wrap the column named null in back-ticks or double quotes in your query, for example:

SELECT </span>null<span class="token punctuation"> FROM table_name

or

SELECT "null" FROM table_name

This works both in regular queries and those executed with ON CLUSTER.
