I have 5 sample questions which I have been given to prepare me for an SQL interview. I have been given a schema of 4 tables and the questions include joins/subqueries, rollups, etc. I. would like someone to give me solutions to the 5 questions and an explanation as to what is happening in the solutions. I would also like someone who doesn't mind fielding a few additional questions afterwards if I am struggling to get my head around your solutions.
I have no doubt that this will be a very straightforward job for an SQL expert. I am looking for someone who can have the solutions back to me in under 24 hrs.
Please note that I am using Postgresql.
