    goodsid,
    count,
    rank() over(partition by category order by count desc) rk
  from(
    select
      category,
      goodsid,
      count(*) count
    from dwd_display_log
    where dt='2019-10-03' and action=2
    group by category, goodsid
  )t1
)t2
where rk<=10;

​
if [[ -n $1 ]]; then
    do_date=$1
else
    do_date=`date -d '-1 day' +%F`
fi
​
sql="
use gmall;
insert into table ads_goods_display_top10
select
  '$do_date',
  category,
  goodsid,
  count
from(
  select
    category,
    goodsid,
    count,
    rank() over(partition by category order by count desc) rk
  from(
    select
      category,
      goodsid,
      count(*) count
    from dwd_display_log
    where dt='$do_date' and action=2
    group by category, goodsid
  )t1
)t2
where rk<=10
"
​
$hive -e "$sql"

2）增加脚本执行权限

chmod 777 ads_goods_display_top10.sh

3）脚本使用
