Added Ability to Send Queries INSERT INTO Tbl VALUES

Why it matters

This feature simplifies client-server interaction by allowing single-statement INSERT INTO queries with inline values. It removes the need to separate the query structure from the actual data, making data insertion more straightforward and compatible with typical SQL usage patterns.

How to use it

Users can send complete INSERT INTO tbl VALUES (...) queries directly to the ClickHouse server without any special handling or splitting. Just execute the query as a single statement in the usual way.
