Variables in Query

Hi All,

 

I'm using a powerbi dataset to load, transform and then store reports in a SQL database (Via [R]). I'm wondering if its possible to set up a simple variable that can be called to create a different temporary table in the SQL statement.

 

i.e. for the first dataset being transformed have the variable set to 1 so the sql statement could be "... INSERT INTO Table" & VARIABLE & " ............" and then with the second query the variable would need to be incremented by 1 and so on for however many queries I end up having to load this way....

    Hi SACooper,

     

    Something like this?

    let
    Source = {1..10},
    #"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Added Custom" = Table.AddColumn(#"Converted to Table", "Custom", each "... INSERT INTO Table" & Text.From([Column1]) & " ............"),
    
    SqlCall = (q as text)=> "Called SQL database with " & q,

    #"Added SqlCall" = Table.AddColumn(#"Added Custom", "SqlCall", each SqlCall([Custom]))
in
    #"Added SqlCall"

     

    Cheers,

    John

      Hi jbwtp 

       

      Apologises for the delay a couple of issues arose at work which took up my time. If i'm reading your solution correctly we'd still need to know the upper limit of the number of queries, or would it not matter if the range was to 100 with only 50 queries (at that point in time)

        How do you know when to stop sending "INSERT INTO" statements?
