Initializing when Oracle record does not exist

[Bob Deskin]

RTFM guys. Look at the ACCESS OPTIONAL option in the QUIZ and QTP manuals 
(I can only vouch for versions F and G but it's probably been that way for 
all of series 8). QUIZ and QTP do things differently because of what QTP 
does with buffers. However, there's a program parameter you can set to get 
the same behavior as QUIZ.

Hello,
 
  When linking to an Oracle table where the record does not exist, Quiz 
and QTP seem to handle it differently. Quiz regards the items in the 
missing record to be null while QTP initializes them to  " " or 0 (for 
char or num type) - ie. the old, familiar, non relational db case.
 
eg. 
 
Access file_a link to Oracle_file_b optional
 
define d_b char*5 = "Null" if b of Oracle_file_b is null
                       else    b of Oracle_file_b 
 
 (I want d_b to be null if b is null, or if the record does not esist)
 
In Quiz if the record Oracle_file_b does not exist, d_b  will be "Null" 
 
In QTP it will be " "
 
Does anyone know why ? I would prefer both Quiz and QTP to act the same 
way and for Oracle files not existing, initialize to null.
 
Because of this, I must add a separate condition in QTP either:
 
  ... or record Oracle_file_b does not exist ...         or
  ... or b of Oracle_file_b = " "
 
Thanks
 
Dan
