STEquals (geometry Data Type)
Returns 1 if a geometry instance represents the same point set as another geometry instance. Returns 0 if it does not.
Składnia
.STEquals ( other_geometry )
Arguments
- other_geometry
Is another geometry instance to compare against the instance on which STEquals() is invoked.
Return Types
SQL Server return type: bit
CLR return type: SqlBoolean
Uwagi
This method always returns null if the spatial reference IDs (SRIDs) of the geometry instances do not match.
Examples
The following example creates two geometry instances with STGeomFromText() that are equal but not trivially equal, and uses STEquals() to test their equality.
DECLARE @g geometry
DECLARE @h geometry;
SET @g = geometry::STGeomFromText('LINESTRING(0 2, 2 0, 4 2)', 0);
SET @h = geometry::STGeomFromText('MULTILINESTRING((4 2, 2 0), (0 2, 2 0))', 0);
SELECT @g.STEquals(@h);
