Has the ability to refresh a dataset with a dynamic SQL stored procedure been disabled?

Up until today, I had a dataset that was able to be refreshed perfectly fine through the Service.  This particular query has a single database as a source, which is an Azure Database.  The dataset us...

    Microsoft have solved this on the backend and it is working again.

Hi Anonymous

 

I think you are possibly right in that something has changed in the underlying Power BI Service and now this is affecting your refreshing of the data from the Azure SQL Database.

Interestingly,  If i change my functions fnStartDate & fnEndDate to return a literal, the problem also goes away.  It is only a problem if i use the dynamic portion of the function.

 

So the problem goes away if I use:

let
    Result = "'2020-01-01'"
in
    Result

instead of:

let
    Result = "'" & DateTime.ToText(DateTime.LocalNow(), "yyyy-MM-dd") & "'"
in
    Result

 

I can only therefore conclude that something in the service is now actively looking for, and blocking, a truly dynamic query.  I was wondering if the functions themselves were enough to cause the problem.  It seems whatever has been put in place is more complex and quite intentional.

 

Sadness :(

    Hi there Anonymous

     

    Are you able to run Profiler on the source database?

     

    The reason that I ask is possibly your initial result is text based, and even though you are specifying the DateTime.ToText I wonder if that is actually happening.

     

    What happens if you change it from the original to

     

    let
    Result = "'" & Text.From(Date.From(DateTime.LocalNow(), "yyyy-MM-dd")) & "'"
in
    Result

    To ensure that it is only passing a Date and not DateTime?

      Really quite a good suggestion GilbertQ, although it didn't pan out.  Same result.

       

      Can you give me some info on the profiler for the source database you are talking about?  Azure is still a little new to me, I haven't been given much access to know what tools are available.  I can get the Azure owner in our organisation to run it for me.

        Hi Anonymous

         

        Pity I was hoping that might be the work around.

         

        SQL Profiler basically returns everything happening on the database. So you are able to see firstly if the query is getting to the database. As well if it is, what exactly it is sending to SQL Server.

         

        If you have a DBA and explain that you want a trace from Power BI, and co-ordinate a time I am fairly certain they will be able to give you the results.
