I need to analyze the temporal trend in this boxing champions dataset. From the evidence, I can see that Begin_reign is the primary temporal column, but the data has formatting issues (some entries start with commas like ",071"). Let me get a clean view of the complete temporal distribution. ```json { "action": "tool_call", "reasoning": "The previous queries attempted to extract years but hit conversion errors or returned empty results. I need to see the full distribution of Begin_reign values to understand the actual format and extract years properly. Let me query all distinct Begin_reign values with their counts to see the pattern.", "tool": "query_sql", "args": { "sql": "SELECT Begin_reign, COUNT(*) as count FROM raw.championsdataset GROUP BY Begin_reign ORDER BY count DESC LIMIT 50", "purpose": "Get all distinct Begin_reign values to understand the date format and distribution", "source": "raw" } } ```
