hive建表语句（包括txt、Orc和分区）
--------------------------------
txt格式 无分区
-------------------------------
use an_pafc_safe;
create table an_pafc_safe.sx_ela_bp_info
(
id_ela_bp_info string,
code string,
agent_no string,
operation_time string,
product_no string,
info_no string,
created_by string,
created_date string,
updated_by string,
updated_date string,
openid string,
page string
)
row format delimited fields terminated by '\t' lines terminated by '\n' stored as textfile;
----delimited fields terminated by '\t' 通过'\t'分割字段
----lines terminated by '\n' 通过'\n'结束一行字段
---------------------------------
Orc格式 无分区
--------------------------------
use an_pafc_safe;
create table an_pafc_safe.dim_olp_bank_table_grade_l
(
branch_grade decimal(38,0),
branch0_code string,
branch0_name string,
branch1_code string,
branch1_name string,
branch2_code string,
branch2_name string,
branch3_code string,
branch3_name string,
branch4_code string,
branch4_name string,
branch5_code string,
branch5_name string,
branch6_code string,
branch6_name string
)
stored as orcfile;
---------------------------------
有分区的hive表
-------------------------------
use an_pafc_safe;
drop table an_pafc_safe.life_mbi_epics_info_yb;
create table an_pafc_safe.life_mbi_epics_info_yb
(
DEPTNO string,
POLNO string,
PLAN_CODE string,
PAYMENT_DATE string,
TOT_MODAL_PREM string,
REGION_CODE string,
AMT_TYPE string,
PREM_TYPE string,
BUSINESS_TYPE string,
BUSINESS_SRC string,
OP_TYPE string,
POL_YR string,
LCD string,
FCD string,
PK_SERIAL string,
bank_channel_type string
)
PARTITIONED BY ( `day` string)
stored as orcfile;
进入hive后，使用对应的集市库和设置相应的参数，然后执行表数据插入操作：
示例一：
use an_pafc_safe;
set mapred.job.queue.name=queue_0101_01;
set hive.exec.dynamic.partition=true;
set hive.exec.dynamic.partition.mode=nonstrict;
set hive.exec.max.dynamic.partitions.pernode = 1000;
set hive.exec.max.dynamic.partitions=1000;
insert overwrite table an_pafc_safe.life_mbi_epics_info_yb partition(day)
select * from an_pafc_safe.life_mbi_epics_info_yb1
示例二：
insert overwrite table an_pafc_safe.bas_ela_agent_info partition(day)
select
id
,code
,parent_code
,type
,type_no
,type_name
,channel
,agent
,openid
,created_date as share_read_time
,referer
,share_source
,share_channel
,detail_no
,wxbind
,substr(created_date,1,10) as statis_date
from sx_360_safe.sx_lvl_trace_info
where substr(created_date,1,10) <'2017-01-01'
and substr(created_date,1,10) <'2017-09-28' ;
