    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:

Thank you so much !

 

I have been racking my brain half the day to make my StartDate and EndDate custom functions readable directly in the Source Query.

 

When I use a SQL statement directly in the Database lookup, I can write BETWEEN '2022-12-01' AND '2022-12-31', and it works perfectly! But this has to be done in the database connection directly.

 

Once i tried editting it directly in the Source Query in PowerQuery - nothing seemed to work. But deleting BETWEEN and rewriting to PowerQuery logic like yours using WITH AND instead - worked just fine now!

 

Thank you 😄
