+
+	* src/test/ressources/QueryExecutorTestCase.properties: 
+	  Changed Test-Query-Statement for Spatial-Queries with INNERJOINS and ORDER BY
+	* src/test/java/de/intevation/gnv/geobackend/base/query/QueryExecutorTestCase.java (testSpatialQueryWithoutIntersects): 
+	  Changed expected Result-Size because of Changes in the QueryStatement which is used.
+	* src/main/java/de/intevation/gnv/geobackend/sde/datasources/ArcSDEStatement.java (executeQuery): 
+	  Added INNERJOIN, ORDER BY and GROUP BY support to Spatial Queries
