+# MySQL 8.0 호환성 문제 해결 가이드
+
+## 🚨 문제 상황
+- **환경**: 시놀로지 NAS Docker 환경 (MySQL 8.0.44)
+- **오류**: `Incorrect arguments to mysqld_stmt_execute`
+- **증상**: 개발 환경(맥미니)에서는 정상 작동하지만 프로덕션 환경에서만 실패
+
+## 🔍 원인 분석
+
+### MySQL 설정 차이
+```sql
+-- 시놀로지 MySQL 8.0 설정
+@@sql_mode: ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
+@@version: 8.0.44
+character_set_database: utf8mb4
+collation_database: utf8mb4_unicode_ci
+```
+
+### Node.js MySQL 드라이버 호환성 문제
+- **문제**: `db.execute()` 메서드의 파라미터 바인딩이 MySQL 8.0의 엄격한 모드에서 호환성 문제 발생
+- **해결**: `db.query()` 메서드 사용으로 변경
+
+## 🛠️ 해결 방법
+
+### 변경 전 (문제 있음)
+```javascript
+const [results] = await this.db.execute(query, [startDate, endDate, parseInt(limit)]);
+```
+
+### 변경 후 (해결됨)
+```javascript
+const [results] = await this.db.query(query, [startDate, endDate, parseInt(limit)]);
+```
+
+## 📊 db.execute vs db.query 차이점
+
+| 구분 | db.execute | db.query |
+|------|------------|----------|
+| **파라미터 바인딩** | Prepared Statement 방식 | 전통적인 쿼리 방식 |
+| **성능** | 반복 실행 시 더 빠름 | 단발성 실행에 적합 |
+| **보안** | SQL Injection 방지 강화 | 기본적인 방지 |
+| **MySQL 8.0 호환성** | 엄격한 모드에서 문제 발생 가능 | 안정적 |
+| **메모리 사용** | 더 효율적 | 상대적으로 많음 |
+
+## 🎯 권장사항
+
+### 1. 환경별 대응
+- **개발 환경**: `db.execute` 사용 가능
+- **프로덕션 환경 (MySQL 8.0)**: `db.query` 사용 권장
+
+### 2. 코드 작성 가이드
+```javascript
+// ✅ 권장: 환경에 따른 분기 처리
+const executeQuery = async (db, query, params) => {
+  try {
+    // MySQL 8.0 엄격 모드 대응
+    return await db.query(query, params);
+  } catch (error) {
+    console.error('Query execution failed:', error);
+    throw error;
+  }
+};
+```
+
+### 3. 테스트 전략
+- 개발 환경과 프로덕션 환경에서 모두 테스트
+- MySQL 버전별 호환성 확인
+- 복잡한 JOIN 쿼리는 특히 주의
+
+## 🔧 적용된 파일
+- `synology_deployment/api/models/WorkAnalysis.js` - `getRecentWork()` 함수
+
+## 📝 참고사항
+- 이 문제는 MySQL 8.0의 `ONLY_FULL_GROUP_BY` 모드와 Node.js MySQL2 드라이버의 호환성 문제로 추정
+- 향후 유사한 문제 발생 시 이 가이드 참조
+- 다른 복잡한 쿼리에서도 동일한 문제가 발생할 수 있음
