)comment ‘姓名表’ with(format =‘ORC’,partitioned_by=array[‘ds’]);
–查询姓名表内容
select * from hive.youyou030310.name;
–查询姓名表格式
desc hive.youyou030310.name;
–insert插入姓名表有分区的值
insert into hive.youyou030310.name(id,name,ds)
values(1,‘张三’,‘20200407’)
,(2,‘李四’,‘20200407’)
,(3,‘王五’,‘20200407’),(4,‘王莉’,‘20200407’),(5,‘王凯’,‘20200407’),

–删除表–
drop table hive.youyou030310.name01;
–查看所有表
use hive.youyou030310;
show tables
—查看最大有分区的内容
select max(ds) from hive.youyou030310.name;
select max(ds) from hive.youyou030310.name;
–联查查看最大有分区的内容
select * from hive.youyou030310.name where ds in(select max(ds) from hive.youyou030310.name);
–创建event有分区
create table hive.youyou030310.even1(
id int comment ‘主键id’,
event_type varchar comment ‘event类型’,
ds varchar comment ‘分区’
)comment ‘event表’ with(format =‘ORC’,partitioned_by=array[‘ds’]);
–插入event有分区
insert into hive.youyou030310.even1(id,event_type,ds)
values (1,‘点击’,‘20200406’),(1,‘查看商品’,‘20200406’),(1,‘购物’,‘20200406’),(2,‘点击’,‘20200406’),(2,‘查看商品’,‘20200406’),(3,‘点击’,‘20200406’);
insert into hive.youyou030310.even1(id,event_type,ds)

sql的常用语法
1、时间怎么表示
select * from hive.youyou030310.ads_basicinfo_df a
where a.create_time >timestamp'2021-01-01 00:00:00'
时间点的大于、等于、小于sql展示
timestamp '2021-01-01 00:00:00
