    "reasoning": "My first query failed because I tried to cast the Amount column (which is VARCHAR) without properly handling its format. The error shows values like '10,000,000,000' which have commas. I need to first understand the actual format of the Amount and Valuation columns before I can analyze them. Let me inspect the columns to see their structure and then look at some sample data to understand the format better."
