MS SQL Server; 63bit signed; Any problems to expect with Xojo?

Hello!

I had months ago the great idea to use 63bit signed as key in database and then wanted to access data by Excel\VBA.
Unfortunately, with 32bit Excel no chance -> maximum number obviously overflown…
Only way was convert into string server side.

I saw Int64 column type is available; Int64 also in Xojo 32bit -> I did read nothing contra.
Both Int64 types are 63bit signed. Seems not a very big deal to handle.

Any problems known handling those numbers?

Apreciate any tip!
Thanks in advance

I wonder if you got a 64 bit anyway internally and it just works.

O.k. I will just check and see if that works.
Thanks!
