if i'm not misunderstood your explanation, tats mean i have to store ex: 2006-10-31 to 3 different columns, (Yr) for 2006, (Mth) for 10 and (Dy) for 31.
By this way i can use the function "GROUP BY" for those columns.
Anyway, will it be any enhancement for function "GROUP BY" in future?
Thanks Stanley.
