Hi.
I have a PowerApp connecting to an Sql database in Azure.
My main case record have a foreign key to a status table, CaseStatusId (FK, int, null)
I have discovered some strange behaviour.
Adding status, OK.
Changing status, OK.
Removing status, setting status to null, failed. The update to the Azure database does not setting the CaseStatusId to null.
I have seen some issues regarding null values with PowerApps, but I have a big problem understanding that this is an issue.
Using normalized data should be strait forward. I mean, using foreign keys like this is really common.

Hi @C3,
What is the related formula that you used for saving the data to Azure SQL? Please share the formula here.

Hi.
My primary table Case, have a foreign key CaseStatusId (int, null) to the table CaseStatus.
This have the primary Key column Id, and a Name column.
In my edit case screen/Form I have a combobox with the CaseStatus (Loaded from a collection)
This Combobox, CaseEditCaseStatusComboBox, is added to the Case.CaseStatus DataCard.
The datacard have Default ThisItem.CaseStatusId and Update(Value(CaseEditCaseStatusDataCardValue.Text))
The Default of CaseEditCaseStatusDataCardValue is CaseEditCaseStatusComboBox.Selected.Id.
So my CaseEditCaseStatusDataCardValue.Text will always reflect the selected value of my Combobox.
Problem is when I clear my combobox. The CaseEditCaseStatusDataCardValue.Text is then "".
The update of the Azure database, will not set my Case.CaseStatusId = null.
Hope this make sense.
