RE: Riddle me this Oracle riddle...

The whole block gets transmitted to Oracle shadow process where it gets executed there.
Sqlnet and the other layers take care of mapping host variables to Oracle shadow process and the PGA.

There is no difference between your pro*C block and executing the same block from sqlplus on your PC.

The warning is only for the IN OUT parameters not for IN parameters.

You can not assign values to an IN parameter and this why referencing it makes sense.
While it's not always for Oracle to assure that in case it's specified IN OUT. Regards,

What about the case where a client Pro*C program (for example) has an embedded
anonymous pl/sql block which does:

begin

    :local_target_variable := procedure xyz(:local_source_variable); end;

You might also consider the warning that goes with the NOCOPY option - to the effect that it is not always possible for NOCOPY to be honoured because it is not always possible for a pointer to be used.

|This is not true. the client does not communicate with the procedure.
Oracle
|shadow process does.
|It's always a pointer.
