STContains siempre devuelve 0 cuando i de la consulta de la tabla. Pero de la misma los datos de los trabajos, cuando yo manualmente crear un polígono de la geometría del objeto y seleccione

Soy nuevo en el sql de la geometría. Tengo una tabla que almacena polígono o multipolígono en una columna. A continuación se da un ejemplo de string fila. La latitud, la longitud, la geom columnas respectivamente

Código anterior funciona perfectamente. Pero, si intento seleccionar de la tabla, que no está funcionando. consulta a continuación

SET @h = geometry::STGeomFromText('POINT(-119.61334353534343 36.84664456779879)', 0);  
SELECT g.geom.STContains(@h) from mygeotable g; 

¿Qué estoy haciendo mal??

Answer 1

Si se ejecuta esta consulta, usted debe conseguir 1 y 1. Como un comentario, usted probablemente le gustaría utilizar un significativo sistema de referencia espacial de identificación, tales como WGS84 (WKID 4326) en lugar de sólo 0 al construir geometrías. Asegúrese de ejecutar sus funciones SQL espaciales en contra de las geometrías que se definen utilizando las mismas referencias espaciales.

create table geometry_polygons(    
    shape geometry
);

DECLARE @g geometry;   
DECLARE @h geometry;   

delete from geometry_polygons
