I need to get basic information about this dataset. Let me start by querying the table overview to get row and column counts. ```json { "action": "tool_call", "reasoning": "The previous query returned 0 rows, which suggests I may have queried the wrong metadata table. Let me query the analytics.table_overview directly to get row and column counts for all tables in the dataset.", "tool": "query_sql", "args": { "sql": "SELECT table_name, row_count, column_count FROM analytics.table_overview ORDER BY table_name", "purpose": "Get row and column counts for all tables in the dataset" } } ```
