-- ============================================
-- 检查 wor_activity_definition 表中 pricing_flag = 0 的数据
-- 用途：分析哪些项目被标记为"不允许划价"，是否符合业务预期
-- ============================================

-- 1. 查看所有 pricing_flag = 0 的项目详情
SELECT 
    id,
    bus_no,
    name AS activity_name,
    category_code,
    type_enum,
    pricing_flag,
    status_enum,
    org_id,
    location_id,
    description_text,
    create_time,
    update_time
FROM wor_activity_definition
WHERE delete_flag = '0'
  AND pricing_flag = '0'  -- 注意：字段类型是 char(1)，所以是字符串 '0'
ORDER BY id;

-- 2. 统计 pricing_flag = 0 的项目数量（按状态）
SELECT 
    status_enum,
    COUNT(*) AS count,
    CASE 
        WHEN status_enum = 1 THEN '激活'
        WHEN status_enum = 2 THEN '停用'
        ELSE '其他'
    END AS status_desc
FROM wor_activity_definition
WHERE delete_flag = '0'
  AND pricing_flag = '0'
GROUP BY status_enum
ORDER BY status_enum;

-- 3. 检查 pricing_flag = 0 的项目是否有关联的费用定价
SELECT 
    T1.id,
    T1.bus_no,
    T1.name AS activity_name,
    T1.pricing_flag,
    T1.status_enum,
    T2.id AS charge_item_definition_id,
    T2.charge_name,
    T2.price,
    T2.status_enum AS charge_status,
    CASE 
        WHEN T2.id IS NOT NULL THEN '有费用定价但不允许划价（可能异常）'
        ELSE '无费用定价，不允许划价（正常）'
    END AS analysis
FROM wor_activity_definition AS T1
LEFT JOIN adm_charge_item_definition AS T2
    ON T2.instance_id = T1.id
    AND T2.delete_flag = '0'
    AND T2.status_enum = 1
    AND T2.instance_table = 'wor_activity_definition'
WHERE T1.delete_flag = '0'
  AND T1.pricing_flag = '0'
ORDER BY T1.id;

-- 4. 检查 pricing_flag = 0 的项目是否在收费项目表中被使用
SELECT 
    T1.id AS activity_id,
    T1.bus_no,
    T1.name AS activity_name,
    T1.pricing_flag,
    COUNT(T3.id) AS charge_item_count,
    CASE 
        WHEN COUNT(T3.id) > 0 THEN '已被使用（可能异常：不允许划价但已有收费记录）'
        ELSE '未被使用（正常）'
    END AS analysis
FROM wor_activity_definition AS T1
LEFT JOIN adm_charge_item AS T3
    ON T3.product_id = T1.id
    AND T3.context_enum = 3  -- ACTIVITY
    AND T3.delete_flag = '0'
WHERE T1.delete_flag = '0'
  AND T1.pricing_flag = '0'
GROUP BY T1.id, T1.bus_no, T1.name, T1.pricing_flag
HAVING COUNT(T3.id) > 0  -- 只显示已被使用的
ORDER BY charge_item_count DESC;

-- 5. 按类别统计 pricing_flag = 0 的项目
SELECT 
    category_code,
    COUNT(*) AS count,
    STRING_AGG(name, ', ') AS activity_names  -- 列出项目名称
FROM wor_activity_definition
WHERE delete_flag = '0'
  AND pricing_flag = '0'
  AND status_enum = 1  -- 只统计激活的
GROUP BY category_code
ORDER BY category_code;

-- 6. 对比：pricing_flag = 0 和 pricing_flag = 1 的项目特征
SELECT 
    pricing_flag,
    COUNT(*) AS count,
    COUNT(DISTINCT category_code) AS category_count,
    COUNT(DISTINCT org_id) AS org_count,
    STRING_AGG(DISTINCT category_code::text, ', ') AS categories
FROM wor_activity_definition
WHERE delete_flag = '0'
  AND status_enum = 1
  AND pricing_flag IN ('0', '1')
GROUP BY pricing_flag
ORDER BY pricing_flag;

-- 7. 检查是否有子项的项目（childrenJson 不为空）被标记为 pricing_flag = 0
SELECT 
    id,
    bus_no,
    name AS activity_name,
    pricing_flag,
    children_json,
    CASE 
        WHEN children_json IS NOT NULL AND children_json != '' THEN '有子项但不允许划价（可能是套餐子项）'
        ELSE '无子项'
    END AS analysis
FROM wor_activity_definition
WHERE delete_flag = '0'
  AND pricing_flag = '0'
  AND children_json IS NOT NULL
  AND children_json != ''
ORDER BY id;

-- 8. 查看 pricing_flag 字段的所有可能值（包括 NULL）
SELECT 
    COALESCE(pricing_flag::text, 'NULL') AS pricing_flag_value,
    COUNT(*) AS count,
    ROUND(COUNT(*) * 100.0 / SUM(COUNT(*)) OVER (), 2) AS percentage
FROM wor_activity_definition
WHERE delete_flag = '0'
  AND status_enum = 1
GROUP BY pricing_flag
ORDER BY pricing_flag NULLS LAST;
