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，主鍵是一種primary key，因此不能有。

 

若是有主鍵，則不能是appendonly 表，爲了追求查詢性能，由於用外部表導入的話，插入不是問題了。
