    order_id,
    teacher_id,
    student_name,
    record_date,
    record_type,
    content,
    supplement,

-- 4. 统计有多少条记录有 supplement 内容
SELECT 
    COUNT(*) as total_records,
    COUNT(supplement) as records_with_supplement,
    COUNT(CASE WHEN supplement IS NOT NULL AND supplement != '' THEN 1 END) as records_with_content
FROM growth_record;
