I need to check for duplicate rows in the dataset. Let me start by examining the structure and then look for exact duplicates. ```json { "action": "tool_call", "reasoning": "First, I'll check for exact duplicate rows by grouping on all columns and finding rows that appear more than once. Since the dataset has 1,311 rows and 69 columns in raw.epoch_ai_benchmarks, I'll use a GROUP BY approach to identify any complete duplicates.", "tool": "query_sql", "args": { "sql": "WITH duplicates AS (SELECT *, COUNT(*) as duplicate_count FROM raw.epoch_ai_benchmarks GROUP BY ALL HAVING COUNT(*) > 1) SELECT duplicate_count, COUNT(*) as num_groups FROM duplicates GROUP BY duplicate_count ORDER BY duplicate_count DESC", "purpose": "Check for exact duplicate rows by grouping on all columns and counting occurrences" } } ```
