hive建立分区表，以当天日期（“2014-08-15”）作为分区依据，hql如下：
CREATE EXTERNAL TABLE IF NOT EXISTS product_sell( category_id BIGINT, province_id BIGINT, product_id BIGINT, price DOUBLE, sell_num BIGINT ) PARTITIONED BY (ds string) ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\n' STORED AS TEXTFILE; 然后以日期作为分区依据，插入数据，shell脚本如下：
#!/bin/bash source /etc/profile;
yesterday=$(date -d '-1 day' '+%Y-%m-%d') lastweek=$(date -d '-1 week' '+%Y-%m-%d')
/usr/local/cloud/hive/bin/hive<<EOF INSERT OVERWRITE TABLE product_sell PARTITION (ds='$yesterday') select a.category_id, b.good_receiver_province_id as province_id, a.id as product_id, (b.sell_amount/b.sell_num) as price, b.sell_num from product a join (select si.product_id, s.good_receiver_province_id, sum(si.order_item_amount) sell_amount, sum(si.order_item_num) sell_num from so_item si join so s on (si.order_id=s.id) where si.is_gift=0 and si.is_hidden=0 and si.ds between '$lastweek' and '$yesterday' group by s.good_receiver_province_id, si.product_id) b on (a.id=b.product_id); EOF 原文：https://blog.csdn.net/yeweiouyang/article/details/38589281
