Q51. The STRING_TAB table has the following structure:
View the Exhibit and examine the code.
What is the outcome on execution?
A. It displays
Output buffer not long enough.
This is my test string.-.
B. It displays only
Output buffer not long enough, and exits the anonymous block.
C. It displays only
This is my test string. - Because EXCEPTION should have been defined in the anonymous

D. It does not display any of the MEMS_PUTPUT messages and gives an error because a
transaction control statement cannot be used in the exception section of a procedure.
Q52. Which three statements are true about wrapping? (Choose three.)
A. The PL/SQL wrapper detects and reports only syntax errors.

C. When wrapping a package or object type, both the body and specification should be wrapped.
D. When wrapping a package or object type, only the body should be wrapped, not the specification.
E. To change a wrapped object, the original source code needs to be modified and then wrapped again
F. To change a wrapped object, the wrapped code can be unwrapped, modified In a text file, and then wrapped again.

A. Users with definer's rights who are granted access to a procedure that updates a table must be granted access to the table itself.
B. Reuse of parsed PL/SQL code that becomes available in the shared SQL area of the server avoids the parsing overhead of SQL statements at run time.
