    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:

Hey did you get any work around for the same?

 

I have also been working on Huge Set of tables and need to filter them based on the bases of date.

 

Please let me know is there a way to implement the same.

 

Appreciate the Help!

Step one is creating your custom SQL statement. I like to add my placeholder for a parameter when I create the SQL statements and replace those with the parameter once defined. The parameters need to be concatenated to the query using & outside of the quotes holding the query. If you created a table with a single SQL query, your M may look like the following.

 

Non-Parameterized Query

let
Source = Sql.Database("MyTestServer", "MyTestDatabase", [Query="SELECT test_key from MyFactTestTable WHERE datekey >= 20190101 AND datekey <= 20190201"])
in
Source

 

Parameterized Query

let
Source = Sql.Database("MyTestServer", "MyTestDatabase", [Query="SELECT test_key from MyFactTestTable WHERE datekey >= " & StartDate & " AND datekey <= " & CloseDate"])
in
Source
