   CREATE TABLE `duplicate_table_with_null` (
               k0 int,v1 date,v2 datetime,v3 char(20),v4 varchar(40),v5 string
               ) ENGINE=OLAP
           DUPLICATE KEY(k0)
           COMMENT "OLAP"

           PROPERTIES (
               "replication_num" = "3",
               "storage_format" = "v2"
           );
