Add support for single-element tuples in IN operator
Add support for (an unusual) case where the arguments in the IN operator are single-element tuples. #49844 (MikhailBurdukov).Why it matters
This feature addresses an unusual syntax scenario in ClickHouse where theIN operator is used with single-element tuples as arguments. It improves query flexibility and correctness by allowing such expressions to work as expected without errors or unexpected behavior.How to use it
Users can now write queries using theIN operator with single-element tuples directly in their SQL statements without needing any special configuration or workarounds.
