次のSELECT文は、エラーを返します。これは、ターゲットのデータ型にTIMESTAMP WITH TIME ZONEデータ型が存在しないためです。

SELECT CAST(TIMESTAMP '2008-06-01 08:30:00' AS TIMESTAMP(0) 
   AT LOCAL);
SELECT CAST(TIMESTAMP '2008-06-01 08:30:00+01:00' AS TIMESTAMP(0) 
   AT LOCAL);
SELECT CAST(TIMESTAMP '2008-06-01 08:30:00' AS TIMESTAMP(0) 
   AT SOURCE TIME ZONE);
SELECT CAST(TIMESTAMP '2008-06-01 08:30:00+01:00' AS TIMESTAMP(0) 
   AT SOURCE);
