Question

I want to select distinct values for a column ‘language’, where the ‘project_ID’ is equal to a specific value, from a table called ‘screenshots’ in my database.

I know how to do this (but it gives me the distinct languages in the entire ‘screenshots’ table):

var result = db.screenshots.Select(m => m.language).Distinct();

How can I add a where clause to my query to ensure that I only get the distinct language values where the project_ID of that column is equal to a specific value?

In plain old SQL this would be the query I want to achieve:

select distinct language from screenshots
where projects_ID=31

Thanks

First you want to apply where clause, and then select distinct. Here it is in code

db.screenshots.Where(m => m.ProjectId == 31).Select(m => m.language).Distinct();
