doris建表出现这么问题怎么解决啊

use example_db; CREATE TABLE table1 ( siteid INT DEFAULT '10', citycode SMALLINT, username VARCHAR(32) DEFAULT '', pv BIGINT SUM DEFAULT '0' ) AGGREGATE KEY(siteid, citycode, username) DISTRIBUTED BY HASH(siteid) BUCKETS 10 PROPERTIES("replication_num" = "1");

insert into table1 (siteid, citycode, username, pv) values (0, 0, "user1", 100), (1, 0, "user2", 100),(2, 1, "user3", 100),(3, 0, "user2", 200);

select * from table1;
