Examples

A. Testing CircularString type for compatibility with compatibility level 110

The following example tests a CircularString instance for compatibility with an earlier version of [!INCLUDEssNoVersion]:

 DECLARE @g geometry = 'CIRCULARSTRING(3 4, 8 9, 5 6)'; 
 IF @g.MinDbCompatibilityLevel() <= 110 
 BEGIN 
 SELECT @g.ToString(); 
 END

B. Testing LineString type for compatibility with compatibility level 100

The following example tests a LineString instance for compatibility with [!INCLUDEsql2008-md]:

 DECLARE @g geometry = 'LINESTRING(3 4, 8 9, 5 6)'; 
 IF @g.MinDbCompatibilityLevel() <= 100
