How to make a dropdown list

[Anonymous]

I want a dropdown list which combines tow columns "FROM_CURRENCY" (CAD, USD...) and "To_CURRENCY" (CAD, USD...)in Sql server. EX: CAD -> USD and USD -> CAD are the same and I write them as CADUSD. I also want them not to be repetitive.

Can someone help me with that?

Thanks

Add a custom column in Query Editor.

Text.Combine(List.Sort({[FROM_CURRENCY],[To_CURRENCY]}))
