-- 工单：(无)
-- 目的：dim_usr_user_ful_d 日常增量（kb/28 §1.3）：
--       昨日 dim (dt=${pdt}) + 今日 ods 增量 (dt=${dt}) 按 user_id 合并去重，落 dt=${dt} 单分区
-- 状态：[草案]
-- 备注：sched=T，${dt}=T-1，${pdt}=T-2；
--       (a) 找今日变更 user_id 集合（base 或 cert 任一变）
--       (b) 这些 user_id 扫 ods dt<=${dt} 重新取最新 base + cert（兼顾 base 没变只 cert 变 / cert 没变只 base 变）
--       (c) 昨日 dim 中没变的 user_id 直接保留
--       (d) UNION ALL 写入 dim dt=${dt} 单分区；
--       cert_info update_time 几乎全空，ORDER BY 用 COALESCE(update_time, create_time)；
--       前置 DS DEPENDENT：ods_usr_app_base_user_inc_d.dt=${dt} + ods_usr_app_user_cert_info_inc_d.dt=${dt} + dim_usr_user_ful_d.dt=${pdt}
