SQL Server return type: bit
CLR return type: SqlBoolean
Uwagi
STContains() always returns null if the spatial reference IDs (SRIDs) of the geometry instances do not match.
Examples
The following example uses STContains() to test two geometry instances to see if the first instance contains the second instance.
DECLARE @g geometry;
DECLARE @h geometry;
SET @g = geometry::STGeomFromText('POLYGON((0 0, 2 0, 2 2, 0 2, 0 0))', 0);
SET @h = geometry::STGeomFromText('POINT(1 1)', 0);
SELECT @g.STContains(@h);
