PROPERTIES (
"replication_allocation" = "tag.location.default: 1"
);

CREATE TABLE `t_2` (
  `code` VARCHAR(36) NULL
) ENGINE=OLAP
DUPLICATE KEY(`code`)
DISTRIBUTED BY HASH(`code`) BUCKETS 1
PROPERTIES (
"replication_allocation" = "tag.location.default: 1"
);

insert into t_1(`code`) values('100');
insert into t_1(`code`) values('200');
insert into t_1(`code`) values('300');

insert into t_2(`code`) values('1');
insert into t_2(`code`) values('101');
insert into t_2(`code`) values('951744758986133504');

SELECT random(1,randnum) AS vnum,m.* 
FROM (select * from t_2) m
