Oracle Error Message
PLW-05003: same actual parameter(string and string) at IN and NOCOPY may have side effects
Reason for the Error
The indicated parameter was declared with the NOCOPY hint in the subprogram specification but not in the body, or it was declared with the NOCOPY hint in the body but not in the specification.
Solution
Ensure that the specification and the body agree in their use of NOCOPY. If this mismatch is not corrected, the program will obey the declaration given in the specification, ignoring that in the body.
