Patch function to SQL table with Identity ON.

[jpyszkowski]

Hello,

I am trying to develop a simple app that allows me to update values in a SSMS table. The column id_num is set to Identity yet I still get the error that my Datasource needs to be a collection. Can Powerapps directly update a SQL server table? Do I need to update the collection first and then send those updates to SQL?

Any help is appreciated. Thanks.

Hi @jpyszkowski 

I think this is because your id_num isn't set as a primary key. If you right click the id_num column in SSMS (in the top part of the grid in your second screenshot), there should be an option to set the column as primary key.

After you do this in SSMS, you'll need to refresh the datasource in PowerApps. There have been some cases in the past few weeks where it's taken some time for such changes to take effect, but this should hopefully solve your problem.

@timl Thank you much. Took about 5 mins for powerapps to refresh and pick up that change.

You're welcome, glad that solved the problem.

I have a created a table in sql database with one column Id as Identity(1,1). Please let me know what value should be passed to the patch for Id Column.

Patch(
'[dbo].[Data]',
Defaults('[dbo].[Data]'),
{
Id: ??? (What should be passed here)

Name :DataCard_Name.Selected.Result})

An identity value is one that's auto generated by SQL Server. Therefore, you omit this column when you call patch.
