Nested tables

Posted on by russrimm1

Hi all,

I'm having trouble trying to figure out the proper way to get at data within tables within a collection.

The collection "availableapps" has a column "Application" which has tables with one row in each. It also has a column "States" which has tables with one row in each. I'm needing to get the first row from each table within those columns, and ideally the Username column as well (that's not as important). I've tried various combinations of First and Filter and LookUp to get at the first rows in each, to no avail. Any pointers would be greatly appreciated.

hi @russrimm1

can you please share the syntax of the first function you used? First(collection).columnname should return the first value to you.

Hi @rubin_boer
I've tried just about everything I can think of. I'm trying to get put the DisplayName of the Applications in a dropdown, and then based on which DisplayName is picked, Set the "ModelName" to a variable. I just figured out if I use a gallery and set the datasource to the collection, ThisItem,Application.DisplayName will display the names of the apps, but I ultimately would like them to show in a dropdown, and that's what i'm having trouble with now.

Hi @russrimm1

If you set the items property of your drop-down to the following formula, ApplicationName should return the display name of the first record in the child application table.

AddColumns(availableapps, "ApplicationName", First(Application).DisplayName )

If that works, you can logically extend the formula to include the application state name

AddColumns(availableapps, "ApplicationName", First(Application).DisplayName, "ApplicationState", First(AppState).AppState )

Thanks @timl, so in doing that, it looks like Application is actually a record, not a table after all. So with a small adjustment I used:

AddColumns(availableapps,
"ApplicationName",
Application.DisplayName
)
... and it worked! I fought with that for so long and I never thought to use AddColumns. 😞 I'll get it one day. Thanks a TON, I owe you a beer! 🙂
