    I got it to work. Here is my code ( DateBegin & DateEnd parameters have been set to 'text'):

     

    let
    StartDate=DateBegin,
    EndDate=DateEnd,
    Source = Sql.Database("this-is-the-database-url.com", "TableNameHere", 
    [Query="SELECT * FROM [TableNameHere].[dbo].[Logs] WHERE CreatedTime >='" &StartDate& "' AND CreatedTime <='" &EndDate& "' ", 
    CommandTimeout=#duration(0, 0, 10, 0), HierarchicalNavigation=true, MultiSubnetFailover=true])
in
    Source

    Oddly enough, I got a bunch of error messages when exiting the 'Query Editor' (as show in my previous post) but when I created everything again from scratch, it works perfectly. 

     

    I then saved the Power BI document as a template. When you open the template, you get prompted to enter the "DateBegin" and "DateEnd" parameters. Enter the parameters and the SQL query gets made, voila! :cathappy:

I've seen tutorials where the Power BI report is saved as a template and upon opening the template, the report asks to choose from a list of parameters (country for example). Are you telling me there is no way to implement SQL date queries in this manner? I'm currently working with a massive SQL table which has several gigabytes of data. Naturally, I can't download the entire thing and do the filtering within the view. I really need a way for the user to be able to define the SQL query one way or another.
