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 query the raw table to check for exact duplicate rows by grouping on all meaningful columns (excluding metadata columns like _ingestion_timestamp, _batch_id, _source_file, _source_system which are ingestion artifacts) and counting occurrences. This will identify any rows that appear more than once.", "tool": "query_sql", "args": { "sql": "SELECT Day, \"Total Calls\", \"AI Handled\", \"Human Handled\", Voicemail, \"AI Resolution %\", \"Human %\", _unnamed_7, _unnamed_8, _unnamed_9, COUNT(*) as occurrence_count FROM raw.callyeah_analytics_2026_07_23 GROUP BY Day, \"Total Calls\", \"AI Handled\", \"Human Handled\", Voicemail, \"AI Resolution %\", \"Human %\", _unnamed_7, _unnamed_8, _unnamed_9 HAVING COUNT(*) > 1 ORDER BY occurrence_count DESC", "purpose": "Check for exact duplicate rows by grouping on all business columns and finding groups with more than one occurrence", "source": "raw" } } ```
