I need to analyze the correlation data in the `table_correlations` table. From the inspection, I can see that correlation matrices are stored in the `matrix_json` column, with corresponding column names in `columns_json`. Let me query this data to find the strongest correlations. ```json { "action": "tool_call", "reasoning": "The table_correlations table contains correlation matrices in matrix_json with column names in columns_json. I'll parse these JSON fields to extract the strongest correlations across all datasets, excluding perfect self-correlations (1.0).", "tool": "query_sql", "args": { "sql": "WITH parsed_correlations AS (SELECT dataset_id, tables_catalog_id, method, columns_json, matrix_json, json_array_length(columns_json) as num_cols FROM raw.table_correlations), expanded AS (SELECT dataset_id, tables_catalog_id, method, json_extract_string(columns_json, '$[' || i || ']') as col1, json_extract_string(columns_json, '$[' || j || ']') as col2, CAST(json_extract_string(matrix_json, '$[' || i || '][' || j || ']') AS DOUBLE) as correlation FROM parsed_correlations, LATERAL (SELECT UNNEST(range(0, num_cols)) as i) t1, LATERAL (SELECT UNNEST(range(0, num_cols)) as j) t2 WHERE i < j) SELECT col1, col2, correlation, dataset_id FROM expanded WHERE correlation IS NOT NULL ORDER BY ABS(correlation) DESC LIMIT 50", "purpose": "Extract and rank the strongest correlations between column pairs across all datasets, excluding self-correlations" } } ```
