I need to identify the categorical columns and count their distinct values. From the dataset card, the CLASSIFIERS section lists categorical columns with approximate distinct counts, but I should verify these with actual data. Let me query the distinct counts for all categorical columns in one SQL query: ```json { "action": "tool_call", "reasoning": "The card lists Cabin, Parch, Pclass, Sex, and Survived as classifiers. I'll write one SQL query to count distinct values for all categorical columns at once, which is more efficient than querying each separately.", "tool": "query_sql", "args": { "sql": "SELECT COUNT(DISTINCT Cabin) as distinct_Cabin, COUNT(DISTINCT Parch) as distinct_Parch, COUNT(DISTINCT Pclass) as distinct_Pclass, COUNT(DISTINCT Sex) as distinct_Sex, COUNT(DISTINCT Survived) as distinct_Survived, COUNT(DISTINCT Embarked) as distinct_Embarked, COUNT(DISTINCT Ticket) as distinct_Ticket FROM raw.titanic", "purpose": "Count distinct values for all categorical columns in the Titanic dataset", "source": "raw" } } ```
