Oracle Error Message

PLW-07203: parameter ‘string’ may benefit from use of the NOCOPY compiler hint

Reason for the Error

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

Solution

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);
