Thank you vegas_castle !
With your client, the game no longer crashes when I click on Cadie.
However, I cannot buy her ingame, so here is a stored procedure :

Code:
CREATE Proc AddCadieTo
@userid varchar(32)
as
DECLARE @UID int
select @UID = UID from Pangya_Member_Info where userid = @userid
IF @UID > 0
BEGIN

INSERT INTO PangYa_Caddie_Info (uid, typeid, RegDate, Period, EndDate, RentFlag)
VALUES (@UID, 469762055,  getdate(), 30, getdate() + 30, 0);

RETURN
END
GO
Please note that I deliberately set the RentFlag to 0.
That way, the Cadie will never expire.
It should be the same for Titanboo.

Cheers.
