Prompt

Task Objective: Incrementally insert new user records (user_id, loss_day) into the ds=20260608 partition of the target table that have not appeared before.

Inputs:

• internal_platform_db.t_mg_dws_user_tag_preset_24128_query_engine_103 (source table, containing fields such as ds, user_id, loss_day)
• internal_platform_db.t_mg_dws_user_tag_user_id_once_24128_query_engine_103 (existing users table, containing previously written user_id values)

Processing Rules:

1. Select records from the source table internal_platform_db.t_mg_dws_user_tag_preset_24128_query_engine_103 where ds=20260608
2. Use a NOT IN subquery to exclude user_id values that already exist in the existing users table internal_platform_db.t_mg_dws_user_tag_user_id_once_24128_query_engine_103 (deduplication condition: user_id)
3. Extract fields: user_id, loss_day

Output Requirements:

• Output field order: user_id, loss_day
• No deduplication needed (duplicates are already filtered out via NOT IN)

Write Requirements:

• Target table: internal_platform_db.t_mg_dws_user_tag_user_id_once_24128_cand_query_engine_103
• Write method: INSERT INTO (append)

Please write the final HiveSQL to result.sql and execute it.
