            How can I optimize multiple conditional database calls in EF Core to fill multiple lists
            Asked 2020-Oct-08 at 20:22

            I am in a bit of a bind, I am a student that has taken a liking to C#/.NET Core and love to work on my hobby project with it. But I have trouble finding a solution for my current problem and I am not sure how to fix it.

            In .NET Core I want to show the top 10 statistics about racing drivers in my motorsport database. To be more precisise, I have a relational database with a table named "DriverResults" which holds all the racing results of all the drivers, "DriverResults" holds a Foreign Key to "SeasonDriver" which is a table containing information about a driver for that specific season and lastly "SeasonDriver" contains a Foreign Key to the "Driver" table which contains who the driver is. I want to make a leaderlist with how often one certain driver has won a race, for example.

            The leaderlistsModel is the ViewModel for the page and contains 5 Lists with each List containing a Driver object and an int for a calculated statistic. To acquire those the Controller of the leaderlist calls a method to get those leaderlists, the method goes like this:

            It looks like you are pulling the entire dataset 5 times into memory. If I got my analysis correct then it could be more efficient to retrieve it only once, by adding a .ToList() after the query definition:

            Having an issue with the switch operator

            Did I screw up the code or is it the ! not working like that and do I need to do a switch (true) & case (VS_WRNG != "")?

            ...

            ANSWER

            Answered 2020-Jun-25 at 22:06

            The primary issue you're having is that !VS_WRNG always results in a boolean. It can never result in an empty string "". So the case "": will never run. But even if it did, your code still won't work:

            In this action I am trying to say... if VS_WRNG is Blank and if VS_WRNG is DSC or DSQ then set the two items

            VS_WRNG cannot be simultaneously Blank and DSC or DSQ. You need to rethink your logic - the requirements are incompatible right now and quite illogical.

            This is also quite an abuse of switch statements. If your switch statement has one case, it's an if statement. Just use an if statement like this:
