STEquals (geometry Data Type)
Applies to:
SQL Server
Azure SQL Database
Azure SQL Managed Instance
SQL analytics endpoint in Microsoft Fabric
Warehouse in Microsoft Fabric
Returns 1 if a geometry instance represents the same point set as another geometry instance. Returns 0 if it does not.
Syntax
.STEquals ( other_geometry )
Note
To view Transact-SQL syntax for SQL Server 2014 (12.x) and earlier versions, see Previous versions documentation.
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
Remarks
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);
