需求1：分析用户使用移动端购买还是PC端购买，及移动端和PC端的用户比例，生成ismobilehive表，存储统计结果；

建表，ismobilehive

  
insert into table ismobilehive select 'Android',count(*) from comment where is_mobile = 'Android客户端';
insert into table ismobilehive select 'IOS',count(*) from comment where is_mobile = 'IOS客户端';
insert into table ismobilehive select 'PC',count(*) from comment where is_mobile = 'PC端';

需求2：分析用户评论周期（收到货后，一般多久进行评论），生成dayssql表，存储统计结果；

    
create table dayssql(
day int,
num string
)
row format delimited fields terminated by ',';

**************************************************************************************************************
insert into table dayssql select '0',count(*) from comment01 where days = '0';
insert into table dayssql select '1',count(*) from comment01 where days = '1';
insert into table dayssql select '2',count(*) from comment01 where days = '2';
insert into table dayssql select '3',count(*) from comment01 where days = '3';
insert into table dayssql select '4',count(*) from comment01 where days = '4';
insert into table dayssql select '5',count(*) from comment01 where days = '5';
insert into table dayssql select '6',count(*) from comment01 where days = '6';

insert into table dayssql select '大于14天小于21天',count(*) from comment01 where days > '14' and days <= '21';
insert into table dayssql select '大于21天小于30天',count(*) from comment01 where days > '21' and days <= '30';
insert into table dayssql select '大于30天',count(*) from comment01 where days > '30';
**************************************************************************************************************
 

需求3：分析会员级别（判断购买此商品的用户级别），生成userlevelname_out表，存储统计结果；

    
create table userlevelname_out(
level string,
num int
)
row format delimited fields terminated by ',';

insert into table userlevelname_out select 'PLUS会员',count(*) from comment01 where plus = 'PLUS会员';
insert into table userlevelname_out select '非会员',count(*) from comment01 where plus = '非会员';
 

需求4：分析每天评论量，生成creationtime_out表，存储统计结果；

    
create table creationtime_out(
day string,
num int
)
row format delimited fields terminated by ',';

insert into table creationtime_out select '2021年12月',count(*) from comment01 where creationtime between '2021-12-01 00:00:00' and '2021-12-31 24:00:00';
insert into table creationtime_out select '2022年01月',count(*) from comment01 where creationtime between '2022-01-01 00:00:00' and '2022-01-31 24:00:00';
insert into table creationtime_out select '2022年02月',count(*) from comment01 where creationtime between '2022-02-01 00:00:00' and '2022-02-28 24:00:00';
insert into table creationtime_out select '2022年03月',count(*) from comment01 where creationtime between '2022-03-01 00:00:00' and '2022-03-31 24:00:00';

select * from creationtime_out;
 

需求5：日期格式标准化需求5：日期格式标准化

功能为：去掉评论时间的时分秒，只保留年月日

    
create table comment02(
guid string,
nickname string,
content string,
score int,
creationTime string,
is_Top string,
plus string,
referenceTime string,
days int,
is_Mobile string
)
row format delimited fields terminated by ',';

insert into table comment02 select guid,nickname,content,score,substr(creationTime,0,10),is_Top,plus,substr(referenceTime,0,10),days,is_Mobile from comment;
 

4、导出用到的是hive -e可以参考数据清洗——日志 - O_O似曾相识 - 博客园 (cnblogs.com)

5、数据显示
