Help with DW Schema queries

I'm working with multiple servers which have the same database, so I have to combine them. Sometimes they stop working, so I set parametes (ACT_Source...) to indicate if they are online or not.

The first query is currently working. I would like to change the second query (which has a different pattern) to have the same 

I have two types of query and I would like to let them at the same patern.

 

let
    fxConnection =
        (server as text) as table =>
            Table.AddColumn(
                Sql.Database(server, Database, [Query="SELECT... "]),
                "Server",
                each server
            ),
    #"CombinedTables" =
        Table.Combine(List.RemoveNulls(
            {
                if ACT_SourceARA = 1 then
                    fxConnection(ARA)
                else
                    null,
                if ACT_SourceGOI = 1 then
                    fxConnection(GOI)
                else
                    null,
                if ACT_SourceIBI = 1 then
                    fxConnection(IBI)
                else
                    null
            })
        )
in
    #"CombinedTables"

 

This is second query:

 

let
    Source = Sql.Database(server, Database),
    DW_DEClass = Source{[Schema="DW",Item="DEClass"]}[Data]
in
    DW_DEClass

 

I think it should looks like the query bellow. I tried add lines 2 and 3 from second query into the first query, but I don't know exactly what should be changed to make this work.

 

let
    fxConnection =
        (server as text) as table =>
            Table.AddColumn(

              ( Source = Sql.Database(server, Database),
                DW_DEClass = Source{[Schema="DW",Item="DEClass"]}[Data] )

                "Server",
                each server
            ),
    #"CombinedTables" =
        Table.Combine(List.RemoveNulls(
            {
                if ACT_SourceARA = 1 then
                    fxConnection(ARA)
                else
                    null,
                if ACT_SourceGOI = 1 then
                    fxConnection(GOI)
                else
                    null,
                if ACT_SourceIBI = 1 then
                    fxConnection(IBI)
                else
                    null
            })
        )
in
    #"CombinedTables"​

 

I appreciate any help!

Use this (I can't see you passing Database here. You might need to replace Database with something like "Database" here depending upon your database name)

 

let
    fxConnection =
        (server as text) as table =>
            Table.AddColumn(
                Sql.Database(server, Database){[Schema="DW",Item="DEClass"]}[Data],
                "Server",
                each server
            ),
    #"CombinedTables" =
        Table.Combine(List.RemoveNulls(
            {
                if ACT_SourceARA = 1 then
                    fxConnection(ARA)
                else
                    null,
                if ACT_SourceGOI = 1 then
                    fxConnection(GOI)
                else
                    null,
                if ACT_SourceIBI = 1 then
                    fxConnection(IBI)
                else
                    null
            })
        )
in
    #"CombinedTables"
