filter 1 table based on other table


I'm trying to populate a combobox with values from 1 table, filtered on the condition that they are present in a different table
this is a simplified view of my database:
I am trying to display the name field of the addresses table, but only for the ones which codes are present in one of those 3 columns in the planning table

I have tried using this filter:

Filter('[dbo].[BIT_Addresses]',code in(('[dbo].[BIT_Planning]').'Load./disch.') Or code in('[dbo].[BIT_Planning]'.To) Or code in('[dbo].[BIT_Planning]'.From)).name

but that is not giving me all of the names

I've also tried using a flow which executes an SQL query, but I can also not get that result to show in a dropdown menu, this is an example of the json the query returns:

any advice on how I can get the filter to work or how to get the SQL results to show up in my combo box would be greatly appreciated 🙂

Hi @Anonymous ,

Could you please share a bit more about your issue?

Do you mean that you could not get all available values within the ComboBox?


Based on the formula that you provided, I could not find any syntax error with it. Please modify your formula as below:

code in '[dbo].[BIT_Planning]'.'Load./disch.' || code in '[dbo].[BIT_Planning]'.To || code in '[dbo].[BIT_Planning]'.From

then check if the issue is solved.


In addition, please also take a try to save your two SQL Tables records into two separated collections, then use the Collections as data source within your app instead of Original SQL Tables. Please take a try with the following workaround:

Set the OnStart property of the App control or set the OnVisible property of the first screen of your app to following:


Then modify your formula as below:

        code in PlanningCollection.'Load./disch.' || code in PlanningCollection.To || code in PlanningCollection.From

please take a try with above formula, then check if the issue is solved.

Hi @v-xida-msft 

it was indeed not showing all available values in the combobox, it only showed 4 but there should've been 38 options. Even weirder, when I change isSearchable to true, it's not showing anything. 

I tried both your suggestions, unfortunately, they both did not work. The first filter had the same result with only showing 4 results, and the second suggestion showed none.

Hey @v-xida-msft,
do you have anything else I could try?  😕
