Summary
When executing raw SQL queries with SQLAlchemy integration in clickhouse-connect, users may encounter ObjectNotExecutableError: Not an executable object: 'EXISTS TABLE ...' error. This happens because SQLAlchemy (especially in versions 1.4+ and 2.0) requires SQL strings to be wrapped with the text() function before execution.
This PR modifies the query execution logic to wrap raw SQL strings with SQLAlchemy's text() function, ensuring compatibility across SQLAlchemy versions 1.3, 1.4, and 2.0.
