Does this query fetch unnecessary information? Should I change the query?

You are surely returning unnecessary results, to answer your question.

Strongly disagree with marr75. First becasue if you do this poor techinie in most of your queries, you are adding unnecessary load to virtually every query. Database queries need to be written as well optimized s possible as it is is exceedingly painful to later go bnack and rewrite every query in your datbase becasue you used a known poor techinique.

Refactoring in datbases is hard and performance must be considered in design, it is not premature optimaization to use techiniqes that are known to improve performance from the start, it is good design.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
