1.“-e”不进入hive的交互窗口执行sql语句
[atguigu@hadoop102 hive]$ bin/hive -e "select id from student;"
2.“-f”执行脚本中sql语句
(1)在/opt/module/datas目录下创建hivef.sql文件
[atguigu@hadoop102 datas]$ touch hivef.sql
文件中写入正确的sql语句
select *from student;
(2)执行文件中的sql语句
[atguigu@hadoop102 hive]$ bin/hive -f /opt/module/datas/hivef.sql
(3)执行文件中的sql语句并将结果写入文件中
[atguigu@hadoop102 hive]$ bin/hive -f /opt/module/datas/hivef.sql > /opt/module/datas/hive_result.txt
