    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:

All the tutorials and posts I saw were about how to pass the query parameter in the 'M' query in Power BI advance editor and nothing about how to actually pass a parameter by editing the souce query SQL statement. 

 

Any idea about that?

 

The main problem with adding the parameter in the Advanced Editor is that, once its edited there, then the setting wheel next the Source of the query disappears and there is no way to see or edit your SQL statement after that.

Any more insights on this? Does Power BI support passing a parameter to the SQL query?
