STCrosses (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 crosses another geometry instance. Returns 0 if it does not.
Syntax
.STCrosses ( 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 STCrosses()
is invoked.
Return Types
SQL Server return type: bit
CLR return type: SqlBoolean
Remarks
Two geometry instances cross if both of the following conditions are true:
The intersection of the two geometry instances results in a geometry whose dimensions are less than the maximum dimension of the source geometry instances.
The intersection set is interior to both source geometry instances.
This method always returns null if the spatial reference IDs (SRIDs) of the geometry instances do not match.
Examples
The following example uses STCrosses()
to test two geometry
instances to see if they cross.
DECLARE @g geometry;
DECLARE @h geometry;
SET @g = geometry::STGeomFromText('LINESTRING(0 2, 2 0)', 0);
SET @h = geometry::STGeomFromText('LINESTRING(0 0, 2 2)', 0);
SELECT @g.STCrosses(@h);
