[数据库教程]

主要是这两个sql

 

start_log(利用get_json_object函数):

insert overwrite table "$app".dwd_start_log 
PARTITION (dt=$do_date) 
select 
    get_json_object(line,$.mid) mid_id, 
    get_json_object(line,$.uid) user_id, 
    get_json_object(line,$.vc) version_code, 
    get_json_object(line,$.vn) version_name, 
    get_json_object(line,$.l) lang, 
    get_json_object(line,$.sr) source, 
    get_json_object(line,$.os) os, 
    get_json_object(line,$.ar) area, 
    get_json_object(line,$.md) model,

use "$APP"; 
insert overwrite table "$APP".dwd_base_event_log partition(dt=$do_date)
