Oracle Error Message
PLW-05001: previous use of ‘string’ (at line string) conflicts with this use
Reason for the Error
While looking for prior declarations of a variable, constant, or label, the compiler found another declaration with the same name in the same scope. Or, the headers of subprogram in a package specification and body were not identical.
Solution
Check the spelling of the variable, constant, or label name. Also check the names of all parameters and exceptions declared in the same scope. Then, remove or rename the object with the duplicate name. Or, change the headers of the packaged subprogram in the package specification or body so that they are identical.
