You are comparing two query execution plans.Query plan A has an estimated query cost of 1000Query plan B has an estimated query cost of 500What can we conclude from this?A.Query B will take 50% less time to execute than query AB.Query B is more efficient but that has no impact on query execution timeC.Query A is less efficient and most likely slower than a query B.
Question
You are comparing two query execution plans.Query plan A has an estimated query cost of 1000Query plan B has an estimated query cost of 500What can we conclude from this?A.Query B will take 50% less time to execute than query AB.Query B is more efficient but that has no impact on query execution timeC.Query A is less efficient and most likely slower than a query B.
Solution
We can conclude that Query B is more efficient than Query A. The estimated query cost is a measure of the resources needed to execute the query. A lower cost usually means that less resources are needed, which often translates to faster execution times. Therefore, we can infer that Query B will most likely be faster to execute than Query A. However, it's important to note that actual execution times can vary based on a number of factors, including system load and data distribution.
