how to optimize a SQL query using Query plan
Hello everyone
I am new to cache. In an interview i was asked how to optimize a sql query.
I just said I will create index on conditions which are present in where clause. But as per interviewer I should check How query plan is getting executed. This will help in optimizing Sql queries.
I want to know what will be the answer for how to optimize SQL query in cache.
Thanks in advance!!
