    Hi schdef,

     

    You can tansfrom your data to text, then use it into sql query.

     

    Sample: Convert region records to text.

     

    let
    Source=data,
    Region = "'"&Text.Combine(List.Distinct(Source[Region]),"','")&"'"
in
    Region

     

     

    Insert into sql query:

     

    let
Source = Sql.Database("xxxxx", "xxxxx", [Query="SELECT * FROM Sales WHERE Region In ("&Region&")"])
in
Source

I am working in Excel Power Pivot, my parameter list is generated from a table in the worksheet. The list generates well, and it displays correctly in the Query that is supposed to go out to SQL. Everything looks good, except, I am running into  a Formula.Firewall error message complaining that my step 'Source' references other queries and I need to rebuild it.

 

For months, I have been trying to figure out a way to fold dynamic parameters back to SQL. This is the closest I have gotten. I can see how this should work. I can't get around the error message though.

 

Is there something I need to be aware of when connecting to the database? Has something changed in the software that prevents this from folding back as intended? Are there better ways today to accomplish this task?
