+-- 优化 pile_reservation_info 表索引
+-- 目标：提升 queryReservationInfo 接口性能
+-- 创建时间：2026-06-22
+-- ============================================
+
+-- 1. 检查现有索引
+SELECT
+    TABLE_NAME,
+    INDEX_NAME,
+    COLUMN_NAME,
+    SEQ_IN_INDEX,
+    INDEX_TYPE
+FROM
+    information_schema.STATISTICS
+WHERE
+    TABLE_SCHEMA = DATABASE()
+    AND TABLE_NAME = 'pile_reservation_info'
+ORDER BY
+    INDEX_NAME, SEQ_IN_INDEX;
+
+-- 2. 添加复合索引（pile_connector_code + del_flag）
+-- 此索引用于优化 selectByPileConnectorCode 查询
+-- WHERE del_flag = '0' AND pile_connector_code = ?
+ALTER TABLE pile_reservation_info
+ADD INDEX idx_connector_delflag (pile_connector_code, del_flag);
+
+-- 3. 添加复合索引（member_id + pile_sn + status + del_flag）
+-- 此索引用于优化 findByMemberIdAndPileSnAndStatus 查询
+-- 已存在的查询：WHERE del_flag = '0' AND member_id = ? AND pile_sn = ? AND status = ?
+ALTER TABLE pile_reservation_info
+ADD INDEX idx_member_pile_status (member_id, pile_sn, status, del_flag);
+
+-- 4. 添加复合索引（pile_connector_code + reservation_type + status + del_flag）
+-- 此索引用于优化 selectActiveReservationByPileConnectorCode 查询
+-- WHERE del_flag = '0' AND reservation_type = 'single' AND status = '1' AND pile_connector_code = ?
+ALTER TABLE pile_reservation_info
+ADD INDEX idx_connector_type_status (pile_connector_code, reservation_type, status, del_flag);
+
+-- 5. 验证索引创建成功
+SHOW INDEX FROM pile_reservation_info;
+
+-- 6. 分析表以更新统计信息
+ANALYZE TABLE pile_reservation_info;
+
+-- ============================================
+-- 回滚脚本（如需删除索引）
+-- ============================================
