1．“-e”不进入hive的交互窗口执行sql语句

[[email protected] 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

[[email protected] 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

[[email protected] 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

[[email protected] hive]$ bin/hive -f /opt/module/datas/hivef.sql  > /opt/module/datas/hive_result.txt
