Merge Tables Without Matching Data

[S0Fr33]

From a Support Ticket system, due to limitations with API calls,  I have multiple tables with the same column names but different data. The tables are separated by date ranges.

I need to merge these so I can report on different time periods and trends. In my research, I only see merging options where you have matching data. Any ideas are welcome!

So you have something like:

Table1:  col1,col2,col3

Table2:  col1,col2,col3

And you want:

col1,col2,col3,col1a,col2a,col3a

Or do you want to Append the tables together?

I'd like to append the tables together.

P.S. - I read your article on how to get your question answered quickly and am providing a link to 2 sample tables with anonymized data.

Hello @S0Fr33 

add a prefix to every column (example table name) and combine the tables afterwards. I've prepared a very basic code example where you see how this could work

let
	SourceTableA = #table
	(
		{"COLA","COL2"},
		{
			{"a","c"},	{"b","d"},	{"e","f"}
		}
	),
    SourceTableB = #table
	(
		{"COLA","COL2"},
		{
			{"a","c"},	{"b","d"},	{"e","f"}
		}
	),
    NewColumnNamesTableA = List.Transform(Table.ColumnNames(SourceTableA),each "TableA"&_),
    NewColumnNamesTableB = List.Transform(Table.ColumnNames(SourceTableB),each "TableB"&_),
    RenameTableA = Table.RenameColumns(SourceTableA,List.Zip({Table.ColumnNames(SourceTableA), NewColumnNamesTableA})),
    RenameTableB = Table.RenameColumns(SourceTableB,List.Zip({Table.ColumnNames(SourceTableB), NewColumnNamesTableB})),
    Combine = Table.Combine({RenameTableA, RenameTableB})
in
	Combine

Copy paste this code to the advanced editor in a new blank query to see how the solution works. If this solution fits your need, copy and past a part of it and implement it in your query.
