I need to identify which columns are numeric (candidates for correlation) and which categorical columns might have strong associations. From the inspect_columns result, I can see several numeric columns (AGE, SUBJID, SITEID, DMDY) and many categorical columns. I should first get the complete column list for both tables to understand all available columns, then compute correlations for numeric columns and examine associations for categorical ones.",
