[!INCLUDE SQL Server Azure SQL Database Azure SQL Managed Instance FabricSQLDB]
Returns 1 if a geometry instance completely contains another geometry instance. Returns 0 if it does not.
.STContains ( other_geometry )
other_geometry
Is another geometry instance to compare against the instance on which STContains() is invoked.
[!INCLUDEssNoVersion] return type: bit
CLR return type: SqlBoolean
STContains() always returns null if the spatial reference IDs (SRIDs) of the geometry instances do not match.
The following example uses STContains() to test two geometry instances to see if the first instance contains the second instance.
DECLARE @g geometry;
DECLARE @h geometry;
SET @g = geometry::STGeomFromText('POLYGON((0 0, 2 0, 2 2, 0 2, 0 0))', 0);
SET @h = geometry::STGeomFromText('POINT(1 1)', 0);
SELECT @g.STContains(@h);
