Adding a new record to SQL Server where there is a uniqueidenfier with a GUID

NOTE: whomever marked my last question as SPAM I would appreciate it if you would not do that. This is a legitimate request for help, and am mystified as to why someone flagged it as spam.

 

I have a form to edit/add records in a SQL table. Edits are easy. Adding not so much.

 

The table has a field that is the primary key, field type "uniqueidentifier", and is a GUID. I cannot set it as Identity YES on the SQL server where it would automatically populate on the server as that apparently only works with integers, not uniqueidentifier fields. (In otherwords, the solution here doesn't work)

 

I cannot for the life of me get a data card that has a normal DataCardValue that will let me stick GUID() in there. It is a required field, but adding the card doesn't give the the StarVisible or ErrorMessage fields, so PowerApps knows something is weird about this field.

 

This is how the field looks on the form:

20190715 18_27_20-Customer Service Maintenance - Saved (Unpublished) - PowerApps.png

You can see it doesn't have the bold blue box around it. It is like it is an uneditable field, which I don't want the user to edit. I just have it here for troubleshooting and was trying to get the UID field to be a GUID() function if this was a NEW form, but SubmitForm() won't take it.

 

So I used Patch(). This is my "Save" button function.

 

If(
    frmBBBFacilityCodeEdit.Mode = FormMode.Edit,
    SubmitForm(frmBBBFacilityCodeEdit),
    Patch(
        '[dbo].[tblBBBPoolFacilityCodes]',
        Defaults('[dbo].[tblBBBPoolFacilityCodes]'),
        {
            FacilityCode: DataCardValue1.Text,
            BuildingID: DataCardValue2.Text,
            ProviderName: DataCardValue3.Text,
            StreetAddress: DataCardValue11.Text,
            City: DataCardValue4.Text,
            State: DataCardValue10.Text,
            ZipCode: DataCardValue13.Text,
            TransitDays: Value(DataCardValue12.Text),
            StartDate: DataCardValue9.SelectedDate,
            UID: GUID()
        }
    )
);
Navigate(
    scrBBBFacilityCodes,
    ScreenTransition.Fade
);
UpdateContext({FacilityCodeUpperCase: ""})

Now, saving does add the record, and the last part of the PATCH() function adds a GUID, so this works, but this is U.G.L.Y. If this has to be this way, I will rename all of my DataCardValueX cards to something meaningful, as well as add the rest of the fields that are not required (about 6 fields missing).

 

But is there any other way to add a GUID to a record that is required? I cannot get it to work with SubmitForm() since it doesn't seem to see the UID field properly

Re: Adding a new record to SQL Server where there is a uniqueidenfier with a GUID

Hi Yutliu,

 

It is actually supported. In my PATCH() statement, I am generating and writing to the GUID field, and SQL Server happliy accepts it in the uniqueidentifier field set to only take a GUID.

 

GUID() writes a valid GUID to SQL ServerGUID() writes a valid GUID to SQL Server

It is just a pain because as far as I can tell, I must use PATCH() to do it, which means I have:

  1. Explicitly write each required field in one PATCH() function.
  2. Write optional fields that have a constraint (like a phone number field) after confirming they meet the restraint, and are not blank.
  3. Write optoinal fields that are not blank and have no constraints. 

SUBMITFORM() does all of the above much more easily, except it cannot handle the GUID field even if I try to feed the GUID() result to it.

Thanks for the other link. Additional info always helpful.

I'm going to accept my own answer as a solution unless someone has something better for me and I'll change it to a better answer as the solution.

Re: Adding a new record to SQL Server where there is a uniqueidenfier with a GUID

Hi @EdHansberry ,

Do you want to update an uniqueidentifier field of SQL Server in PowerApps?
I'm afraid it's not supported to read and write GUID data type from CDS or SQL yet.

Here's a similar issue for your reference:

https://powerusers.microsoft.com/t5/General-Discussion/How-to-get-the-GUID-of-the-newly-created-d365...

As analternative way, I suggest you insert a char type in SQL server to record Guid.

And set this column's data to GUID().

In this way, this column will be updated successfullt with Guid data.
