Prompt

Task Objective: From the news plugin send process flow table, aggregate and compute metrics such as send count, send UV, panel exposure count, panel exposure UV, inner-page PV, and inner-page UV by the scene (pos_desc) dimension, across two time windows — current day and last 1 hour — and write the results to the output table.

Input Table:

• internal_platform_db.dwm_news_plugin_ai_assistant_send_process_flow_hi_prestosql_006 (news plugin send process flow table)
  • imp_hour BIGINT — hourly partition
  • user_id STRING — user ID
  • content_id STRING — content ID
  • push_id STRING — push ID
  • pos STRING — position
  • send_cnt BIGINT — send count
  • panel_exp_cnt BIGINT — panel exposure count
  • pgin_pv BIGINT — inner-page PV
  • pos_desc STRING — position description (scene)
  • account_code STRING — business code

Output Requirements:

• Target table: internal_platform_db.ads_news_plugin_ai_assistant_hourly_report_cand_prestosql_006

• Output fields and order:

  • imp_hour BIGINT — hourly partition
  • scene STRING — scene (pos_desc)
  • send_cnt_dth BIGINT — current day send count (SUM(send_cnt) WHERE imp_hour <= current hour)
  • send_uv_dth BIGINT — current day send UV (COUNT(DISTINCT user_id) WHERE imp_hour <= current hour)
  • panel_exp_cnt_dth BIGINT — current day panel exposure count (SUM(panel_exp_cnt) WHERE imp_hour <= current hour)
  • panel_exp_uv_dth BIGINT — current day panel exposure UV (COUNT(DISTINCT user_id) WHERE panel_exp_cnt > 0 AND imp_hour <= current hour)
  • pgin_pv_dth BIGINT — current day inner-page PV (SUM(pgin_pv) WHERE imp_hour <= current hour)
  • pgin_uv_dth BIGINT — current day inner-page UV (COUNT(DISTINCT user_id) WHERE pgin_pv > 0 AND imp_hour <= current hour)
  • send_cnt_1h BIGINT — last 1 hour send count (SUM(send_cnt) WHERE imp_hour = current hour)
  • send_uv_1h BIGINT — last 1 hour send UV
  • panel_exp_cnt_1h BIGINT — last 1 hour panel exposure count
  • panel_exp_uv_1h BIGINT — last 1 hour panel exposure UV
  • pgin_pv_1h BIGINT — last 1 hour inner-page PV
  • pgin_uv_1h BIGINT — last 1 hour inner-page UV

• Simplified explanation: For each imp_hour + pos_desc combination, compute the current day cumulative (dth) and current hour (1h) aggregation metrics

• If the target table does not exist, first create the table, then write the data

• Use Presto/Trino SQL syntax; do not use Hive/Spark SQL dialects

Environment and Execution Notes:

• Presto is running, connected via the Hive catalog
• Execute SQL: presto-cli --catalog hive --schema internal_platform_db -f /tmp_workspace/result.sql
• After writing result.sql, you must execute it yourself to verify that it runs successfully and produces correct data
