Can I add fields from multiple data sources into a single gallery of items?

Hi,

 

I have recently started to build apps on my Android. I have 2 data sources.

 

1. Table 1{ID, Name, Date, Ticket Details}

2. Table 2 {ID, Name, Region}

 

I would like to be able to display items based on Region selected.  I am thinking to use Filter function on Table 1 by Region but I would need to somehow join the 2 tables by common field [Name] in order to be able to do so.

 

Any idea or help will be appreciated. Thank U!

 

Cheers

Boon Yar

You need to simulate a join operation on the two tables. This can be done in multiple ways, for example via unique join keys or duplicate join keys. Are there any duplicates in your Name column? Depending on this, and whether you care about duplicates or not, try the following:

 

1. Join with duplicate Names

 

    gallery1.Items = AddColumns(Table1, "Region", LookUp(Table2, Name = Table1[@Name], Region))

 

2. Join with no duplicate Names (will produce nested data)

 

    gallery1.Items = AddColumns(

        GroupBy(Table1, "Name", "NameGroup"),

        "Group",

        AddColumns(NameGroup, "Region", LookUp(Table2, Name = NameGroup[@Name], Region)))

 

 

If you want to join on a different field, say "ID", use that field in either of the two inner lookups above (as in "ID = NameGroup[@ID]").

 

I hope this helps!

You can Collection feature for this purpose.

https://powerapps.microsoft.com/en-us/tutorials/function-clear-collect-clearcollect/

 

Use "Collect" function to get set of rows from Source1 and then again use "Collect" function to get rows from Source2. "Collect" function appends the records.

 

Hope this helps you.

Hi Perumal,

 

Thank you for your response.

 

Yes i did try collect. However, for my case, how can I apply collect to lookup fields and combine them into a single collection.. Just as stated in my example.

 

Thank you.

@boonyar With the answers you found, I also got my app working with two sources, but my problem now is that the edit form doesn't work. Did you manage to do it for your app?

A couple of things.  First... Where are putting this code?  You guys always leave these important steps out.  Second, I have a SharePoint form based on a list, let's call it 'List 1'.  I want to set one of lIst 1's fields, well call it 'Field 2' , to a value looked up in List 2, based on a common Field (Field 1) in both lists.  

 

List.Field1 has the data I want to key on in List 2's field 1.   I want to set =Field2 to a value in List 2, based on a a value in List1.Field1 = List2.Field1.  

 

In SQL is would be  "Select Field2 from List1, where List1.Field1 = List2,Field1"

 

Any ideas on how I do this?

So Sorry... havent been logging in for a while. Yes edit form should work too.
