If Oracle decides not to use your index, apply an INDEX() hint and look at the new plan. The cost will be greater than the plan it did choose - this is why it didn't pick your index. The hinted plan might lead to some insight about why your index is not good.

2020年10月20日  If I make the index, can I prove that the new index was used? Solution. The answer is an emphatic yes! SQL Server can help advise if an index will help a query run faster. It can even estimate how much the index will help. The best way to determine this is to use the query execution plan. This tip will walk through how to generate ...

The EXPLAIN PLAN statement displays execution plans that the optimizer chooses for SELECT, UPDATE, INSERT, and DELETE statements..

The estimated execution plan, for all practical purposes, uses statistics and many other parameters based on what is available on this server and generates the plan. This is an estimated plan and not specifically the plan that has been generated by SQL Server. This is synonymous to the first analogy that we had given about the weather forecast.

2014年7月13日  If the query plan really changes significantly on the parameter value, maybe you should not use bind variables for this parameter. How many different values can that parameter take? If there are only a few, you would end up with a couple of query plans (one for each value), and those would hopefully perform well and can be re-used.

Tip: Constant scan operator shows that optimizer is creating one or more rows for the next stages of the query processing When we analyze the query plan, we see only a constant scan operator because, during the execution of the query, the Product table isn’t read by the database engine because of the 1=0 expression. This expression is evaluated as a contradiction by the query

Every execution plan has been evaluated and the best one chosen. There isn’t enough time to evaluate every plan, and the best one thus far is chosen. Once an execution plan is chosen, the query optimizer’s job is complete and we can move to the final step of query processing. Execution is the final step.
