How to Merge Two Tables (Vertical Merge)

[matthewtian777]

I want to merge below two tables in Power BI. They have same columns, so I hope to vertically merge below two tables.

I know the best way is to go to "Edit Queries"->"Append Queries". However, as these two tables are generated by DAX from other tables, they cannot be shown in Power Query Editor. So I don't know what to do with this situation.

Hey @matthewtian777 ,

I actually don't understand what you mean by "vertically merge"

If you want to use the equivalent of "Append Queries" -> You could use the UNION-TableFunction.

If you need to join the tables in DAX you could use

• NATURALLEFTOUTERJOIN
• NATURALINNERJOIN
• ADDCOLUMNS

If this post was helpful may I ask you to mark it as solution and give it some kudos?

Have a nice day!

BR,
Josef

@JosefPrakljacic Thank you, Josef! The UNION function is exactly what I want.
