| ## 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. |
