描述

Currently when querying a POINT data type it will fail, because MySQL returns a binary encoded value.

Ideally Redash would decode the POINT components (x,y) and return those, but I couldn't find an obvious way in Python to do this conversion.

研究方向
Investigate the MySQL query runner in the Redash codebase (likely redash/query runner/mysql.py). Understand how Redash currently processes MySQL query results. Look into decoding the binary POINT representation using Python's struct module or converting to WKT format via MySQL's ST AsText function. Consider testing with sample POINT data to ensure correct x,y extraction.
