looking for most efficient way to join 2 tables into a 3rd

[vffdd]

I have 2 Tables 

For example

1.

AB1	Apple
AB2	Orange
AB3	Lettuce
AB4	Cucumber
AB5	Pear

Table 2

AB1	Fruit
AB2	Fruit
AB5	Fruit

I would like a 3rd table that show only the records in Table 1 that are NOT in Table 2.. So for example

AB3	Lettuce
AB4	Cucumber

I then need to use that table as a datasource in powerapps.

I'm trying to figure out the most efficient way to do this?  Yes I could do it with collections in Powerapps.. however is there a better way to do it at the dataverse end?  or maybe should I even create a dataflow that creates this table?  suggestions welcome 🙂

TIA

Hello, @vffdd, you can achieve this via Dataflows/Power Query. Create your third table in Dataverse and then create a Dataflow and implement a Join in the power query.

Thanks @AhmedSalih  I've actually decided to do it in the powerapp itself and not create a 3rd table using this method.
