PLW-07203: parameter 'string' may benefit from use of the NOCOPY compiler hint..

Answer / guest

Cause: The mode of the specified parameter was IN OUT or
OUT. Use of the NOCOPY compiler hint may speed up calls to
this subprogram.

Action: Change the mode of the parameter to explicitly use
the NOCOPY compiler hint. For example, if your subprogram
declaration is: PROCEDURE proc(p1 IN OUT CLOB); you can
change it to: PROCEDURE proc(p1 IN OUT NOCOPY clob); to get
the benefit of the NOCOPY hint. For member procedures or
functions in object types, you may have to explicitly
declare the SELF parameter as illustrated in the following:
MEMBER PROCEDURE proc(SELF IN OUT NOCOPY MY_TYPE);
