-- 家庭信息父母信息和特殊情况字段录入问题排查脚本
-- 问题：新增学生信息时，家庭信息填了，但父母信息和特殊情况没有录入数据库

-- 1. 检查数据库表结构，确认父母信息和特殊情况字段存在
SHOW COLUMNS FROM hzdyjs_xg.xg_student_info WHERE Field LIKE '%father%' OR Field LIKE '%mother%' OR Field LIKE '%is_%';

-- 2. 检查数据库中是否有父母信息数据
SELECT student_no, name, father_name, father_phone, mother_name, mother_phone 
FROM hzdyjs_xg.xg_student_info 
WHERE (father_name IS NOT NULL AND father_name != '') OR (mother_name IS NOT NULL AND mother_name != '')
LIMIT 10;

-- 3. 检查数据库中是否有特殊情况数据
SELECT student_no, name, is_poor_student, is_minority, is_disabled, is_orphan, is_left_behind_child, is_single_child
FROM hzdyjs_xg.xg_student_info 
WHERE is_poor_student = 1 OR is_minority = 1 OR is_disabled = 1 OR is_orphan = 1 OR is_left_behind_child = 1 OR is_single_child = 1
LIMIT 10;

-- 4. 检查所有学生的父母信息和特殊情况字段分布
SELECT 
    COUNT(*) as total_students,
    COUNT(father_name) as has_father_name,
    COUNT(mother_name) as has_mother_name,
    COUNT(CASE WHEN father_name IS NOT NULL AND father_name != '' THEN 1 END) as has_valid_father_name,
    COUNT(CASE WHEN mother_name IS NOT NULL AND mother_name != '' THEN 1 END) as has_valid_mother_name,
    SUM(is_poor_student) as poor_students,
    SUM(is_minority) as minority_students,
    SUM(is_disabled) as disabled_students,
    SUM(is_orphan) as orphan_students,
    SUM(is_left_behind_child) as left_behind_students,
    SUM(is_single_child) as single_child_students
FROM hzdyjs_xg.xg_student_info 
WHERE deleted = 0;

-- 5. 检查最近创建的学生记录的父母信息和特殊情况
SELECT 
    id, student_no, name, 
    father_name, father_phone, father_work_unit,
    mother_name, mother_phone, mother_work_unit,
    is_poor_student, is_minority, is_disabled, is_orphan, is_left_behind_child, is_single_child,
    create_time
FROM hzdyjs_xg.xg_student_info 
WHERE deleted = 0 
ORDER BY create_time DESC 
LIMIT 10;

-- 6. 检查特定学生的完整家庭信息
SELECT 
    id, student_no, name,
    -- 父母信息
    father_name, father_phone, father_work_unit,
    mother_name, mother_phone, mother_work_unit,
    -- 家庭情况
    family_income, family_members,
    -- 特殊情况
    is_poor_student, is_minority, is_disabled, is_orphan, is_left_behind_child, is_single_child,
    -- 紧急联系人
    emergency_contact_name, emergency_contact_phone, emergency_contact_relation
FROM hzdyjs_xg.xg_student_info 
WHERE student_no = '2024001' OR student_no = '2024002' OR student_no = '2024003'
ORDER BY student_no;

-- 问题分析：
-- 1. 前端表单字段：fatherName, motherName, isPoorStudent, isMinority 等正确绑定
-- 2. 数据库字段：father_name, mother_name, is_poor_student, is_minority 等存在
-- 3. 实体类映射：@TableField注解正确映射
-- 4. ResultMap映射：正确映射了所有字段
-- 5. selectVoPage查询：缺少大部分父母信息和特殊情况字段
-- 
-- 结论：问题在于 XgStudentInfoMapper.xml 的 selectVoPage 查询语句中缺少以下字段：
-- - father_name, father_phone, father_work_unit
-- - mother_name, mother_phone, mother_work_unit  
-- - is_minority, is_disabled, is_orphan, is_left_behind_child, is_single_child
-- 
-- 只包含了 is_poor_student，其他字段都缺失！
