STAGE3 OK

問題：
Line 345 將家族成員 ID 載入內存（ToList）
- 如果家族有 100+ 成員，載入 100-400 bytes

優化：
移除 ToList()，改為使用 IQueryable 子查詢
- var ccList = cc.ToList(); // 移除
- 直接使用 cc 進行 Contains 查詢
- 生成 SQL: WHERE num IN (SELECT...) OR leader IN (SELECT...)

效果：
✓ 減少內存占用：100-400 bytes → 0
✓ 完全在數據庫執行
✓ SQL 優化器可以更好地優化查詢計劃

對比：
- 原始版本（載入內存）：2 次查詢
- 優化版本（子查詢）：1 次查詢（最佳）

+
+### 📈 **資料表統計**
+
+| 功能模組 | 主要資料表數量 | 核心業務表 |
+|---------|-------------|-----------|
+| 報名管理 | 5個 | `pro_order`, `pro_order_detail` |
+| 信眾管理 | 2個 | `followers`, `countries` |
+| 活動管理 | 2個 | `activity`, `activity_kind` |
+| 匯款沖帳 | 3個 | `transfer_register`, `accounting`, `pro_order_record` |
+
+### 🎯 **系統特色**
+
+1. **模組化設計**：每個功能模組都有獨立的資料表群組
+2. **關聯完整**：透過外鍵建立完整的業務關聯關係
+3. **狀態管理**：多個狀態表支援複雜的業務流程
+4. **UUID設計**：新模組採用UUID作為主鍵，提升擴展性
+5. **軟刪除機制**：使用`IsDeleted`欄位而非物理刪除
+
+這個資料表架構支援了一個完整的宗教活動管理ERP系統，涵蓋了從信眾管理、活動報名、床位安排到財務沖帳的全流程管理。

+# 報表系統規劃
+為每場活動(法會)建立報名到舉辦過程的報表,
+要涵蓋以下面向的統計分析資訊
+
+- 以單一場法會為核心
+- 時間面向: 當前狀況, 指定期間狀況
+- 維度:
+  - 信眾: 報名數量, 金額, 收款狀態
+  - 牌位型態(活動品項表): 報名數量, 金額, 收款狀態
+  - 收款狀態: 己收/未收 統計明細
+
+## 執行方式:
+- 類似excel, 詳細資料->pivot table
+- 先建立一個(或數個)最核心的sql view, 包含各項:報名資料, 收款明細
+  - 先以單一活動編號為固定FILTER : activity.num=59
+- 再依不同面向, 建立第二級的sql view
+- 再人工將以上:第一, 第二級的SQL VIEW, 以EXCEL查詢, 做資料分析/整理
+- 相關英文欄名, 在VIEW中以中文別名顯示
+
+## 相關SQL VIEW
+- (查詢清單)
+### (查詢)

+# Pivot Module 執行計劃
+
+## 概述
+建立多頁籤數據透視查詢模組，參考 transfer 模組的設計架構，使用相同的技術棧與 UI/UX 模式，實現法會報名資料的多維度分析與展示。
+
+---
+
+## 技術架構
+
+### 前端技術
+- **框架**: Vue.js 2.x + Vuetify 2.x（與 transfer 模組一致）
+- **表格元件**: v-data-table（Vuetify 內建表格元件）
+- **頁籤元件**: v-tabs / v-tab / v-tab-item（Vuetify 頁籤）
+- **UI 框架**: Bootstrap 5 + Bootstrap Icons（MasterPage）
+- **樣式**: 與 transfer 模組保持一致的視覺風格
+
+### 後端 API
+- **框架**: ASP.NET Web API（C#）
+- **ORM**: Entity Framework + LINQ
+- **控制器**: `App_Code/api/pivotController.cs`（已建立）
+- **資料庫視圖**: `報名明細查詢`（SQL View）
+
+### 資料流架構（重要）★
+```
+查詢流程:
+┌─────────────┐
+│   Tab 1     │ → 選擇法會 → API 查詢一次 → 
+│  查詢條件   │              (完整資料集)
+└─────────────┘
+       ↓
+┌─────────────────────────────────────────┐
+│  Vue Data (存於前端 this.rawData)        │
+│  - 完整報名明細                           │
+│  - 一次性載入，不重複查詢                 │
+└─────────────────────────────────────────┘
+       ↓
+┌──────┬──────┬──────┬──────┬──────┐
+│Tab 2 │Tab 3 │Tab 4 │Tab 5 │Tab 6 │
+│明細  │信眾  │收入  │趨勢  │對比  │
+│      │      │      │      │      │
+│ 純前端計算 / 過濾 / 分組 / 統計       │
+│ 使用 computed / methods / filters    │
+└──────────────────────────────────────┘
+```
+
+**優點**:
+1. ✅ **效能優化**: API 只查詢一次，減少伺服器負載
+2. ✅ **即時響應**: 切換頁籤無延遲，使用者體驗佳
+3. ✅ **離線分析**: 資料載入後可離線操作（過濾、排序、統計）
+4. ✅ **減少流量**: 不重複傳輸相同資料
+5. ✅ **一致性**: 所有頁籤基於同一份資料，確保一致性
+
+**技術實現**:
+- `this.rawData`: 原始完整資料（Tab 1 查詢後存入）
+- `computed properties`: 各頁籤的資料來源（動態計算）
+- `methods`: 過濾、分組、統計邏輯
+- `watch`: 監聽過濾條件變化
+
+### 元件規格
+1. **日期選擇器**: `v-date-picker` 或 `<input type="date">`
+2. **下拉選單**: `v-select`（年份、月份、法會選擇）
+3. **資料表格**: `v-data-table`（分頁、排序、過濾）
+4. **頁籤切換**: `v-tabs`（Tab 1~N）
+5. **按鈕群組**: `v-btn`（查詢、匯出、重設）
+6. **載入狀態**: `:loading="loading"`
+7. **視覺標記**: Bootstrap Badge（橙、藍、綠、紫色標籤）
+
+---
+
+## 頁籤設計
+
+### Tab 1: 查詢條件設定
+**功能目標**: 提供查詢條件，篩選法會並選擇目標法會
+
+#### UI 布局

+
+#### 查詢流程
+1. 選擇年份（2020~2025）或月份（1~12）
+2. 點擊「查詢法會」按鈕
+3. API 回傳該期間的法會清單（`api/pivot/activity_stats`）
+4. 表格呈現法會清單（法會名稱、日期、統計）
+5. 點擊「選擇」按鈕，載入該法會的詳細資料
+6. 自動切換到 Tab 2（詳細資料頁籤）
+
+#### API 整合
+- **端點**: `GET api/pivot/activity_stats?startDate={start}&endDate={end}`
+- **回傳**: 法會清單（含報名統計）
+
+#### 資料查詢策略
+```javascript
+// 選擇法會後，一次性載入完整資料
+selectActivity(item) {
+  this.loading = true;
+  this.selectedActivity = item;
+  
+  // 一次性查詢完整報名明細（不分頁）
+  axios.get('/api/pivot/registration_details', {
+    params: {
+      activityNum: item.法會ID,
+      pageSize: 9999  // 取得全部資料
+    }
+  }).then(response => {
+    // 存入原始資料（供所有頁籤使用）
+    this.rawData = response.data.data.list;
+    
+    // 自動切換到 Tab 2
+    this.activeTab = 1;
+    this.loading = false;
+  });

+- ✅ 如資料量過大（>5000 筆），可調整策略改用分頁查詢

+2. ✅ 查詢法會按鈕與 API 整合（`activity_stats`）
+3. ✅ 法會清單表格（v-data-table）
+4. ✅ 選擇法會邏輯（一次性載入完整資料）
+5. ✅ `this.rawData` 資料結構設計
+
+### Phase 3: 實作 Tab 2（報名明細）

+2. ✅ 收入統計分析（Tab 4）- `computed: incomeStats`
+3. ✅ 趨勢分析（Tab 5）- `computed: trendAnalysis`
+4. ✅ 對比分析（Tab 6，選配）- `computed: comparativeAnalysis`
+
+### Phase 5: 優化與測試
+1. ✅ UI/UX 調整（與 transfer 保持一致）
+2. ✅ 效能優化（分頁、快取）
+3. ✅ 瀏覽器相容性測試
+4. ✅ 權限控制（ezAuthorize）
+
+---
+
+## 參考範例
+
+### 1. transfer/verify.aspx
+- 多階段流程設計（程序1、程序2）
+- v-data-table 表格元件使用
+- 信眾選擇對話框（v-dialog）
+- 狀態選擇（v-select）
+
+### 2. transfer/verify1.aspx
+- 單階段流程設計
+- 簡潔的查詢與確認流程
+
+### 3. transfer/index.aspx
+- 功能入口頁面設計
+- Bootstrap Icons + Badge
+- 三欄式布局
+
+---
+
+## 注意事項
+
+1. **元件一致性**: 所有元件、樣式、命名均與 transfer 模組保持一致
+2. **API 規範**: 遵循 RESTful 設計，統一回傳格式
+3. **權限控制**: 所有 API 加上 `[ezAuthorize]`
+4. **效能考量**: 
+   - ✅ **前端計算策略**: Tab 1 查詢一次，Tab 2~6 使用 Vue computed 計算
+   - ✅ **資料量控制**: 單一法會報名明細預估 <5000 筆，適合前端處理
+   - ⚠️ **大資料處理**: 若單場法會 >5000 筆，可改用 API 分頁查詢
+   - ✅ **記憶體管理**: 切換法會時清除舊資料（`this.rawData = []`）
+5. **視覺區隔**: 使用 Badge、邊框色、背景色標記欄位類型
+6. **使用者體驗**: 載入狀態（loading）、錯誤提示（alert）、空資料提示
+7. **前端效能優化**:
+   - 使用 `computed` 而非 `methods`（自動快取）
+   - 大型陣列操作使用 `Object.freeze()` 凍結原始資料
+   - v-data-table 啟用虛擬滾動（`:virtual-scroll="true"`，資料量 >1000 時）

+## SQL View 參考
+
+```SQL
+CREATE VIEW [dbo].[報名明細查詢]
+AS
+SELECT  dbo.activity.num AS 法會ID, dbo.activity.subject AS 法會名稱, dbo.activity.startDate_solar AS 開始日期, dbo.activity.endDate_solar AS 結束日期, 
+               dbo.followers.f_number AS 信眾編號, dbo.followers.u_name AS 信眾姓名, dbo.pro_order.order_no AS 報名編號, dbo.pro_order.up_time AS 報名日期, 
+               CASE WHEN parent_num IS NOT NULL THEN '是' ELSE '否' END AS 功德主, dbo.actItem_kind.kind AS 功德類型, dbo.actItem.subject AS 功德名稱, 
+               dbo.pro_order_detail.qty AS 數量, dbo.pro_order_detail.price AS 金額, 0 AS 已收, dbo.pro_order_detail.price * dbo.pro_order_detail.qty - 0 AS 未收
+FROM     dbo.pro_order_detail INNER JOIN
+               dbo.pro_order ON dbo.pro_order_detail.order_no = dbo.pro_order.order_no INNER JOIN

+               dbo.actItem_kind ON dbo.actItem.kind = dbo.actItem_kind.num
+GO
+```
+
+---
+
+## 資料結構範例
+
+```javascript
+// Vue data 結構
+data() {
+  return {
+    // 原始完整資料（Tab 1 查詢後存入，供所有頁籤使用）
+    rawData: [],  // Array<報名明細物件>
+    
+    // 選中的法會
+    selectedActivity: null,
+    
+    // 當前頁籤索引
+    activeTab: 0,  // 0=Tab1, 1=Tab2, 2=Tab3...
+    
+    // Tab 2 過濾條件
+    filter: {
+      followerName: '',
+      itemKind: null,
+      isParent: null
+    },
+    
+    // Tab 4 分組方式
+    groupBy: 'activity',  // 'monthly', 'yearly', 'activity', 'itemKind'
+    
+    // Tab 5 趨勢設定
+    trendMetric: 'income',  // 'income', 'followers', 'count'
+    trendInterval: 'monthly',  // 'monthly', 'quarterly', 'yearly'
+    
+    // 載入狀態
+    loading: false
+  }
+}
+```
+
+## Vue Computed 效能考量
+
+```javascript
+computed: {
+  // 使用 Object.freeze() 凍結大型陣列，提升效能
+  frozenRawData() {
+    return Object.freeze(this.rawData);
+  },
+  
+  // 各頁籤 computed 基於 frozenRawData
+  filteredRegistrations() {
+    return this.frozenRawData.filter(/* 過濾邏輯 */);
+  }
+}
+```
+
+## 執行確認
+
+請檢視以上計劃，確認以下事項：
+
+1. ✅ 頁籤設計（Tab 1~6）符合需求
+2. ✅ 查詢流程（年/月 → 法會清單 → 明細資料）清晰
+3. ✅ 視覺區隔（色彩標記、Badge）符合 Excel 概念
+4. ✅ 技術架構（Vue + Vuetify + API）與 transfer 一致
+5. ✅ 功能完整性（查詢、過濾、排序、匯出）
+6. ✅ **資料流架構（一次查詢 + 前端計算）**合理且高效 ★
+
+**確認後即開始實作 Phase 1（建立查詢頁面骨架）。**
