I need to get the column metadata to see which columns have missing values. Let me inspect the columns of the championsdataset table to get this information. ```json { "action": "tool_call", "reasoning": "The previous query returned 0 rows, which means either the query was incorrect or there are no missing values. I need to inspect the columns metadata to see the null counts for all columns in the table.", "tool": "inspect_columns", "args": { "table": "championsdataset" } } ```
