[!INCLUDE SQL Server Azure SQL Database Azure SQL Managed Instance FabricSQLDB]
Returns 1 if a geometry instance represents the same point set as another geometry instance. Returns 0 if it does not.
.STEquals ( other_geometry )
other_geometry
Is another geometry instance to compare against the instance on which STEquals() is invoked.
[!INCLUDEssNoVersion] 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);
