shell脚本中写hive的sql语句
2.3 shell脚本中写hive语句
2.3.1 test.sh脚本内容
#!/bin/bash
analysis_date=$1
#开始执行方法
#/opt/hive-2.3.5/bin/hive -e "select count(1) from hv_orders_user_buckets"
echo "输入的参数变量为:$analysis_date"
hive -e "use hv_user_profile;select id from hv_user_index;"
说明：使用“hive -e xxx”语句，前提是配置好hive的环境变量才能这样写。
这个语句中一定要引入 表所在数据库（use xxx）。否则，提示not found table xxx。
hive的每个sql结束的都要有“；”分号。
2.3.2 执行结果
[www@1-11-100 opt]$ sh test.sh 2019
输入的参数变量为:2019
