ClickHouse now throws an exception if a column name in a query cannot be associated with any table.
Why it matters
This feature improves error detection by preventing ambiguous or invalid queries where a column reference does not match any table. It helps users quickly identify and fix errors related to missing or incorrect table associations for columns in their queries.How to use it
This behavior is enabled by default; users will see an exception when executing queries that contain column names unresolvable to any table in the query context.
