Hive表txt文件導入

---- 建表格式
USE databasename;
CREATE TABLE CiiFcst_hotel_forecast_result_type_test(
masterhotel int COMMENT '酒店ID',
ciiquantity  double COMMENT '間夜量'
)
comment '測試表'
PARTITIONED BY(d STRING COMMENT 'date')
row format delimited fields terminated by '\t'
stored as TextFile; 

----- 導入分區數據
hive> load data local inpath 'prevalue1024.txt' into table databasename.CiiFcst_hotel_forecast_result_type_test partition(d='2016-10-24');  

----- 普通表導入
hive> load data local inpath 'city1.txt' into table databasename.CiiFrcst_City_List;

---- 刪除插入

hive> load data local inpath 'prevalue1024.txt' OVERWRITE INTO TABLE databasename.CiiFcst_hotel_forecast_result_type_test partition(d='2016-01-01');
hive> load data local inpath 'prevalue_a.txt' OVERWRITE INTO TABLE databasename.CiiFcst_hotel_forecast_result_type_test partition(d='2016-01-01');
