Try the INTERSECTS command.

INTERSECTS ps OBJECT '{"type":"Point","coordinates":[120.439113,36.350892]}'

尝试INTERSECTS命令。

INTERSECTS ps OBJECT '{"type":"Point","coordinates":[120.439113,36.350892]}'

This statement should return a boolean type,But what I get back is this (integer) 0
2) (empty list or set)
