我有这个复杂的mysql查询，在几千条记录的数据集上，查询性能大大降低。 *_shifted_AllocationDate列是视图的计算列（vw_transaction_details）。
我怎样才能提高它的性能？

Contrxt Info
此查询用于取出有关点分配的不同参数，这些参数充当根据这些参数执行某些操作的进程的输入。这些参数包括total number of transaction on that day/week/month/year per dealer和index(1 base) of transaction on day/week/month/year per dealer。
我已经编辑了我的查询，在select语句中包含了标识列PointsAllocationId。实际上它是原始查询的一部分，但我已经删除了所有非计算列，试图在发布之前使查询变小。

答案 0 :(得分：0)
为了提高性能，我建议避免重复的相关子查询，而是使用条件聚合。
原始查询有点奇怪，从vw_transaction_details返回每一行，但不包括行中的任何标识符或任何其他信息，只包括其他行的计数。
我会做这样的事情：
