Greenplum create table

create table sanguozhi (id bigint, name varchar(32), country varchar(8), url varchar(128), ip varchar(16), uuid varchar(36), agent varchar(128), detail varchar(512), birthday date) WITH (appendonly=true) distributed by (id) partition by range(birthday) (START('0200-01-01') END('0300-01-01') EVERY('0001-00-00'), DEFAULT PARTITION sgz_partition);

appendonly 表不能有unique index，主键是一种primary key，因此不能有。

 

若是有主键，则不能是appendonly 表，为了追求查询性能，由于用外部表导入的话，插入不是问题了。
