cost of marble table top

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

The cost of full table scan is calculated as follows: Cost = ( #SRds * sreadtim + #MRds * mreadtim + CPUCycles / cpuspeed ) / sreadtim During full table scan, the number of reads per block is 0, and # srds indicates the number of reads per block. In the

Topic:The table has n legs, and when the table is unbalanced, it can be cut off to achieve maximum balance. The so-called maximum balance state refers to-the longest leg of the table is more than half the number of legs of the table. But the cost of cutting the legs of the

The following describes how to manually calculate the cost value in the Oracle execution plan. The cost is calculated as follows:Cost = (# Srds * sreadtim +# MRDS * mreadtim +Cpucycles/cpuspeed)/Sreadtime# Srds-number of single block reads# MRDS-number of multi-block reads# Cpucyles-Number of CPU cycles Number of CPU clock cyclesSreadtim-single block read time (unit: milliseconds, 1000 milliseconds equals 1
