procedures. That is, if the batch statement contains multiple queries, the whole batch is not compiled as a whole, and SQL Server is not aware of the local variable values in the batch.

It is worth noting that when there are too many execution plans that lead to too many objects in the Same Bucket after the hash, additional buckets are required, which may lead to low cache efficiency of the search plan. The solution is to minimize the number of plans in t
