ORM Standalone Demo project doesn’t compile in 5.12.10 and Delphi XE5

[VadimMest]

procedure TForm6.btnCreateTableClick(Sender: TObject);
begin
orm.CreateOrUpgradeTable([TPerson,TAccount,TImage{,TBackupImage}]);
end;

[dcc32 Error] Unit1.pas(157): E2001 Ordinal type required
[dcc32 Error] Unit1.pas(157): E2010 Incompatible types: ‘Integer’ and ‘class of TImage’

How to fix it?

Hi,

If I remember it well there where some serious issues in XE5 with generics which are heavily used in the ORM framework. I think you need XE7 or up.

This is a case of XE5 not supporting an implicit creation of an array.
Instead use orm.CreateOrUpgradeTable(TArray<TClass>.Create(TPerson,TAccount,TImage{,TBackupImage}));

Hello

This code works:
orm.UpgradeTable(TArray<TClass>.Create(TMRDOC,TMRDOCROW));

Thanks
