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.
|Applies to: SQL Server (SQL Server 2008 through current version), Azure SQL Database.|
.STEquals ( other_geometry )
Is another geometry instance to compare against the instance on which
STEquals() is invoked.
SQL Server return type: bit
CLR return type: SqlBoolean
This method always returns null if the spatial reference IDs (SRIDs) of the geometry instances do not match.
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);
