i'm using Delphi 10.2 and SDAC 8.0.1. Inserting an empty guid results in exception.
We got a query like this:
Code: Select all
query.Append();
query.FieldByName('GuidField').AsGuid := TGUID.Empty;
query.Post(); // "Invalid class string" exception
Code: Select all
query.Append();
query.FieldByName('GuidField').AsGuid := TGUID.Empty;
query.Post(); // "Invalid class string" exception
