[Solved] Unable to unwrap

I assume that the error message is correct and the coded has been wrapped with a pre Oracle 10g wrap utility. See also FAQ Is unwrapping code processed by the PL/SQL Wrapper of Oracle7, Oracle8, Oracle8i or Oracle9i supported?

Please post the wrapped code, if you think the code has been wrapped with an Oracle 10g or newer wrap utility.

Was unable to wrap function below with error 20>0 unwrap failed

create or replace FUNCTION "MYPROC" wrapped
