Question

I’m trying to choose places from my postgis db that are inside a certain bounding box. I’m trying to accomplish this with this query:

//latlong - latitude, longitude of a place

SELECT * FROM places WHERE St_Contains(St_GeomFromText('Polygon((:top_left_long :top_left_lat, :bottom_right_long :bottom_right_lat))'), latlong);

First of all – I get the following error:

 Warning: PDOStatement::execute(): SQLSTATE[HY093]: Invalid parameter number: :top_left_lat 

What does it mean? And the second issue – am I feeding these parameters in good order? I mean – first longitude, then latitude?

Here is a query I used in an old project:

SELECT param1, param2, ... 
FROM messages 
WHERE ST_Contains( 
    ST_SetSRID(
        ST_MakeBox2D(
            ST_Point(0, 50), ST_Point(50,0)
        ), 
        4326
    ), 
    the_geom
)

the_geom was my geometry column
Note: MakeBox2D take top-left and right-bottom
