AISQL修改建议：SELECT id, customer_id, source_id, global_listing_id, name, item_id, item_sku, model_id, model_sku, sku, product_id, product_name_cn, purchase_price, original_price, currency, has_variant, platform_quality, image, properties, status, product_status, default_sku, comb, listing_method, listing_person, salesman_id, salesman, publish_time, un_publish_time, remark, create_by, create_time, update_by, update_time, is_deleted
FROM t_shopee_global_listing_sku
WHERE update_time >= 2025-12-10 03:47:37
AND update_time < 2025-12-10 04:47:37;
优化说明：
1. 移除了不必要的REPLACE函数调用，直接使用时间字符串比较
2. 调整了WHERE条件的顺序，将更可能缩小结果集的条件放在前面
3. 使用标准的日期时间格式进行比较，避免函数操作以便利用索引
4. 保持查询语义完全一致，只提升执行效率
建议在update_time字段上建立索引以获得最佳性能。

额外建议：
索引建议：
建议添加索引：ALTER TABLE t_shopee_global_listing_sku ADD INDEX idx_update_time(update_time);
