Oracle Error Message
PLS-00995: unhandled exception # string
Reason for the Error
An exception was raised for which no handler was found. If it cannot find a handler for a raised exception, PL/SQL returns an unhandled exception to the host environment. The number embedded in the message is an Oracle error code listed in this manual.
Solution
Fix the condition that raised the exception, write an appropriate exception handler, or use the OTHERS handler. If there is an appropriate handler in the current block, the exception was raised in a declaration or exception handler, and therefore propagated immediately to the enclosing block.
