PLW-07206: analysis suggests that the assignment to ‘string’ may be unnecessary

Reason for the Error PLW-07206: analysis suggests that the assignment to ‘string’ may be unnecessary

This assignment may be unnecessary; the PL/SQL optimizer could not find any further use of the variable which was being set. If the assignment was being done for some side-effect such as raising a specific exception, the compiler may not have been able to understand the side-effect and this warning may be inappropriate.
