Azure SQL DB Patch error: We couldn't convert to Number

I made a post yesterday (my first here) about having problems with patching a table in Azure SQL DB. I would reply to that thread, but I can't find it anywhere, even though I can see it listed as Topics started in my profile... 


Anyway, I was having issues with updating a table with Patch. Inserting a record worked just fine and dandy. The issue seems to be the column name of the primary key... The column name is henkilö_id, and the letter ö is causing the issue. The table and updated columns can have ö's and ä's in their names, and even the primary key with inserting records. Updating just fails with: 
"The requested operation is invalid. Server Response: We couldn't convert to Number. inner exception: We couldn't convert to Number. clientRequestId: 7f924139-2a7d-45c5-9aa7-833864612208"


Yes, I know. Just use the English alphabet and you'll run into less problems... But in case someone else runs into this error, make sure you don't have any weird characters in your primary key column name.

Hi @MrWill ,

Do you mean that you can not patch sucessfully because you use some special characters?

Yes, this will cause some problems. Since the characters that SQL and PowerApps support are not exactly the same.

Some may be supported in SQL, not PowerApps. Some are opposite. This will lead to many problems. To avoid this, I suggest you use generic characters(English word).

If you meet the language problem, you could also try this formula:

MicrosoftTranslator.Translate( "Hello", Language() )
