Right so this 'bde replacement' doesn't actually have a global session variable like the bde - it's private and the only way to access it is to create a TIBOComponent decendant and access it's IB_Session property. Um, can you say 'Cop out'?

Let me give you an example of where I use session.
I use it to get a reference to the database where I only know the database name. E.g.

TMyObject = class
published
...
property DatabaseName: string read FDatabaseName write FDatabaseName;
...
end;

...

procedure TMyObject.Commit;
var DB: TDatabase;
begin
DB := Session.FindDatabase(FDatabaseName);
DB.Commit;
end;

So you are saying to do the above in IBO I would have to do this:

procedure TMyObject.Commit;

function GetGlobalSessionThatIBODoesntExpose: TIB_Session;
begin
with TIBOQuery.Create(nil) do
try
Result := IB_Session
finally
Free;
end;
end;

var DB: TIBODatabase;
begin
DB := TIBODatabase(GetGlobalSessionThatIBODoesntExpose.GetConnectionByName(FDatabaseName));
DB.Commit;
end;

That's ok, I can handle that, but I still think that it's a cop out if the only way to access the **global** default ibo session is through the **property** of an ibocomponent when this is supposed to be a bde replacement. Oh well, life goes on.

Thanks for all your help.
Ben

It's common enough but it's generally pretty obvious.

Read Artur's advice again. "IB_Session" **is** the global session property
of all IB components. A TIBODatabase object **is** an IBO component. The
TIBODataset component exposes this property to its descendants explicitly
through the TIB_ wrapper. Read the property list in the Help.

YourIBODataset.IB_Session.GetConnectionByName

YourIBODatabase.IB_Session.GetConnectionByName

Maybe I've lost track of this thread, but why can't you just read the
DatabaseName property of the IBODatabase?
