I need to check for duplicate rows across the tables in this dataset. Let me start by examining the main transaction table and then check the dimension tables. ```json { "action": "tool_call", "reasoning": "First, I'll check the largest table (b2b_sales_funnel_pipeline with 8,800 rows) for exact duplicates by comparing total row count against distinct row combinations. I'll also check for duplicates on what appear to be natural keys.", "tool": "query_sql", "args": { "sql": "WITH duplicate_check AS (SELECT COUNT(*) as total_rows, COUNT(DISTINCT (opportunity_id, account, product, sales_agent, engage_date, close_date, deal_stage, close_value)) as distinct_combinations FROM raw.b2b_sales_funnel_pipeline) SELECT total_rows, distinct_combinations, total_rows - distinct_combinations as duplicate_count FROM duplicate_check", "purpose": "Check for exact duplicate rows in the main pipeline table" } } ```
