有两张桌子
customer（分区于customer_batch_id）type_stage（非分区，用于某些计算的阶段表）
type_stage完全为空，没有空值，没有空字符串，我的意思是表没有/零行。当我执行以下查询时，它会扫描每个分区，customer当有更多分区时需要很长时间。
inner join当不存在type_stage将跳过分区序列扫描并减少执行时间的记录时，我们如何跳过此操作。
explain analyse
selct * from type_stage ts
inner join customer c on ts.to_id = c.customer_batch_id
where c.order_date <= cast(ts.ini_date as date);
我尝试像这样在内部连接上添加空检查
inner join customer c on ts.to_id is not null and ts.to_id = c.customer_batch_id
但没有行，type_stage它再次给出相同的计划
