Prompt

Task Objective: Extract qualifying records from the input table, parse the JSON array, and explode it into multiple rows, then output to the target table.

Input:

• internal_platform_db.t_eis_feedaggregator2_feedforreddot_check_result_summary_classification_df_query_engine_152

Processing Rules:

1. Filter condition: ds='20260608', regexp_replace(second_update_date, '-', '') = ds, second_status in (1, 2)
2. Core transformation:
   • Extract $.info.titles from the json_buffer_ field as a JSON array string
   • Remove the outermost square brackets of the array, replace },{ with }|{, and split by | to obtain multiple JSON objects
   • Use LATERAL VIEW explode to expand into multiple rows, with one title_obj per row
   • Extract from each title_obj: $.title, $.title_type, $.quality
3. No joins, single-table processing

Output Requirements:

• Output field order: ds, feedid, feedid_v1, type_source, classification, title, title_type, quality, second_status
• The ds field value is fixed as 20260608
• The feedid_v1 field value equals feedid
• No deduplication or aggregation required

Write Requirements:

• Output table: internal_platform_db.dws_rd_feedaggregator_feed_title_quality_di_cand_query_engine_152
• Partition field: ds=20260608
• Write method: INSERT OVERWRITE

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