1.从外部文件系统向表中加载数据 load  [overwrite] into

load data [local] inpath "" [overwrite] into table table_name [partition(col_name="")]

local:表示从本地加载数据到HIVE表，否则从HDFS加载
overwrite:表示覆盖表中已有数据，否则表示追加

（1）从本地上传数据到表格
load data local inpath "/opt/module/datas/student.txt" into table kg_risk_student;

（2）从hdfs上传数据到表格
load data inpath "/student.txt" into table kg_risk_student;

2.通过查询语句向表中插入数据 insert overwrite/into

(1)基本插入数据  overwrite/into
insert overwrite/into table bigdata17-user_parttion partition(userid=1) values("zhang","zhangshan");
(2)根据查询结果插入语句
insert overwrite/into table bigdata17-user_parttion partition(userid=1) select username ,fullname from bigdata17_user;

3.查询语句直接创建并加载数据 as

create table  if not exists student2 as select * from student;

4.创建表时通过Location指定加载数据路径

（1）创建表，并指定hdfs路径
drop table if exists student;
create table if not exists student(
id int,
name string,
gender string)
row format delimited fields terminated by ","
lacation "/user/hive/warehouse/student"
;

（2）数据上传到hdfs
dfs -put /opt/module/datas/student.txt  /user/hive/warehouse/student

(3)查询数据
select * from student

5.import 导入到HIVE

import table student from "/user/hive/warehouse/export/student"
