"in" operator as test of membership and its delegation

[Meneghino]

According to the latest clarification in regards to delegation, the "in" operator is delegable for SQL server.

Also, according to the operator documentation, the "in" operator can be a test of "Belonging to a collection or a table" and not only a test for substrings within strings.

I have failed up to now to make this operator work with SQL server in the following syntax, as not only does it not delegate, but it gives an error as can be seen in the screenshot.

Filter('[Access].[Entities]', ID in [2, 3, 8, 2, 6])

This error however, is not given in this trivial case and the operator works as expected:

Filter([1,2,3,4,5,6,7,8,9], Value in [2, 3, 8, 2, 6])

Has anyone made the operator work with non-trivial data sources and/or in a delegable way as a test for membership?

I am grateful for any insight, since this is needed to join two tables.

I am connected to azure SQL instance and it is NOT working. Well I have still under 500 rows, so I get just a warning.

Just ran into this issue myself, trying to Collect from a SQL Server using a Collection to Filter :

Collect ( Collection1 , Filter ( [dbo] , ID in Collection2.ID ))

Still getting the non-delegable flag and Powerapps telling me my 1-column (Collection2.ID) is not in fact a 1 column table ... And the documentation still says that "in" is delegable with SQL.

Is this still an issue?

Hi everyone.

Yes unfortunately this has always been an issue, PowerApps doesn't delegate the 'in' operator to SQL. This has forced us to use a SQL Query from Flow for Azure SQL, and a Stored Proc from Flow for SQL on premises. Flow does 'n great job to retrieve the data, but it would be a glorious day when PowerApps finally delegates the 'in' operator.

Please try if it helps to use nvarchar type columns. In my tests the IN delegation is working , if the column in your SQL DB is nvarchar. On my case i added extra computed column to database just for this. Or then make a view if it suits your needs.
