Hello, I have read that subqueries perform much slower. I would like to know what are the other options available we can consider instead of using subqueries. I have seen 80% subqueries in the Stored procedures which I am accessing in Java. I remember once we had used Temp table approach to reduce this usage. I am not an expert in Database but occasionally need to write some queries and Stored procedures.
Before diving off into alternatives, perhaps it would be best to ascertain that sub-queries are actually a problem? Just reading it somewhere doesn't mean it's a real issue, and even if they are in certain circumstances, it's best to verify that something is an actual problem in your environment before flying off the handle.
