使用hive的常用命令语句

1、linux进入 hive命令行

beeline

2、查看所有表

show tables;

3、查看是否是分区表

show partitions tableName;

4、查看表前几条记录

select * from tableName limit 10;

5、查看表某一分区数据

select * from tableName where 分区字段=分区 limit 10;

6、创建表(例子)

create table if not exists tableName(

name string,

age int,

sarlar bigint

)row format delimited fields terminated by '\t' stored as textfile;

7、模糊查找表

show tables like '*tableName*';

8.创建视图

create view viewName select * from tableName;

9.删除表

drop table tableName;

10.就文本数据导入hive表

load data local inpath '/usr/data/students.txt' into table studentTable partition(classId=1)

11.创建带有分区的hive表

create table if not exists tb_hive_table(

name string,

age int

) partitioned by(ad string);
