Table name change for each new project

Hi clem312 

You could first connect to project 1 with the native query in your original post to create a query. Then modify its M codes in Advanced editor like below to convert it into a custom function. 

VarAskList and varAskCall are two variables which we use to replace the "AskCall1" and "AskList1" strings in original query codes. I name it as functionQuery.

(varAskList as text, varAskCall as text) =>
let
    Source = Sql.Database("server name", "database name", [Query="SELECT Statistic_Agent.CallID, Lists.dbo." & varAskList & ".AskInterview, Lists.dbo." & varAskList & ".QUOTA7
FROM Lists.dbo." & varAskList & " INNER JOIN
Lists.dbo." & varAskCall & " ON Lists.dbo." & varAskList & ".AskInterview = Lists.dbo." & varAskCall & ".AskInterview INNER JOIN
Statistic_Agent ON Lists.dbo." & varAskCall & ".CallID = Statistic_Agent.CallID", CreateNavigationProperties=false])
in
    Source

Create a table which includes table names for 500 projects.

let
    projectList = List.Generate(() => 1, each _ <= 500, each _ + 1),
    #"Converted to Table" = Table.FromList(projectList, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Renamed Columns" = Table.RenameColumns(#"Converted to Table",{{"Column1", "Project Number"}}),
    #"Added Custom" = Table.AddColumn(#"Renamed Columns", "Table1", each "AskList"&Text.From([Project Number])),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Table2", each "AskCall"&Text.From([Project Number]))
in
    #"Added Custom1"

After that, invoke the function functionQuery to add a new column in the previous table. We use the two table name columns for paramters varAskList and var AskCall in the function.

After invoking the function, you will see a new table column similar to below. Click the expand icon on the column header to expand the tables. You will have all 500 project data in the query.
