I need to check for duplicate rows in the dataset. Let me start by understanding the structure and then look for exact duplicates. ```json { "action": "tool_call", "reasoning": "First, I'll check the main table for exact duplicate rows by grouping on all columns and finding rows that appear more than once. Since the dataset has 61 columns, I'll use a hash-based approach to identify duplicates efficiently.", "tool": "query_sql", "args": { "sql": "WITH row_hashes AS (SELECT hash(*) as row_hash, COUNT(*) as occurrence_count FROM raw.all_ai_models GROUP BY hash(*) HAVING COUNT(*) > 1) SELECT COUNT(*) as duplicate_row_groups, SUM(occurrence_count) as total_duplicate_rows, MAX(occurrence_count) as max_occurrences FROM row_hashes", "purpose": "Check for exact duplicate rows across all columns using hash-based grouping", "source": "raw" } } ```
