The Cost calculation formula for full table scan is as follows: Cost (# SRds * sreadtim + # MRds * mreadtim + CPUCyclescpuspeed) sreadtim: the number of reads per block is 0 during full table scan, # SRds indicates the number of reads per block. In the cost of full table scan, the CPU consumption is actually very small and negligible, so the formula for full tabl
