Если Вы не нашли ответ, вот пример создания базы данных:
CreateDatabase('d:\workspace', 'test6.mdb', ipWorkspace);
procedure CreateDatabase(databaseFolder, databaseName: string;
var pWorkspace: IWorkspace);
var
pPropertySet: IPropertySet;
pWorkspaceName: IWorkspaceName;
pWorkspaceFactory: IWorkspaceFactory;
pName: IName;
pInterface: IInterface;
begin
pWorkspaceFactory := coAccessWorkspaceFactory.Create as IWorkspaceFactory;
pPropertySet := coPropertySet.Create as IPropertySet;
pWorkspaceFactory.Create(databaseFolder, databaseName, pPropertySet, 0, pWorkspaceName);
pName := pWorkspaceName as IName;
pName.Open(pInterface);
pWorkspace := pInterface as IWorkspace;
end;
