PL/SQL Question:
Choose one and only one which is the wrong statement, or the least correct.
1)
- Associative array does not require calling the constructor function to initialize its variable.
- Associative array is the only collection type that allows string (such as varchar2) as index.
- Associative array type can be defined as ... index by integer; .
- Varrays are always dense, no deletion of internal elements is allowed.
- The method of limit will return the null when applied to nested table.
2)
- If an exception occurs in the inner block and it is handled by the exception section in that inner block, then the control passes to the next statement in the outer block.
- Every system internally defined exception has a code (number).
- The system predefined exception has a name, thus the system will not raise the exception automatically.
- Each system internally defined error will be raised by the system automatically if that error occurs in the program during the run time.
- The exception handler cannot handle exception which occurs in the same exception section.
