hive-e封装HQL模板

 hive -e方式

hive -e "待执行sql"。这种方式允许我们在引号中写入需要执行的SQL语句。通常适合于语句较长的情况。这种方式也是在需要进行任务调度时采用的最直接方式，此时可以结合shell定义可变参数(如日期)，再结合调度系统就可以实现脚本自动化。

#!/bin/bash 
ago_day=`date -d '-2days' +%Y%m%d`
hive -e "SET hive.exec.dynamic.partition.mode=nonstrict;
insert overwrite table dim.dim_sku_info_df partition(ds)
