AND sku_id?(warehouse_id, sku_id)按库位查库存WHERE location_id?(location_id)按单号查入库单WHERE asn_no?唯一索引 (asn_no)按状态仓库查出库单WHERE warehouse_id? AND status?(warehouse_id, status)按时间范围查流水WHERE create_time BETWEEN ? AND ?(create_time)按SKU仓库时间查流水WHERE sku_id? AND warehouse_id? AND create_time?(sku_id, warehouse_id, create_time)4.3.2 索引设计原则选择性高的列优先建索引如单号、SKU编码联合索引遵循最左前缀原则避免在索引列上使用函数如 DATE(create_time) 会导致索引失效定期分析慢查询日志优化索引4.4 数据归档策略库存流水表wms_inventory_log数据增长最快建议按月分区或定期归档方案保留最近 6 个月数据在主表更早数据迁移到归档表 ALTER TABLE wms_inventory_log PARTITION BY RANGE (TO_DAYS(create_time)) ( PARTITION p202601 VALUES LESS THAN (TO_DAYS(2026-02-01)), PARTITION p202602 VALUES LESS THAN (TO_DAYS(2026-03-01)), -- ... 按月分区 );
