1z0-148 Exam - Question 40

To ensure this code executes successfully, two main corrections are needed. Firstly, the nested table needs to be extended to accommodate new elements, which is achieved by adding wk#.EXTEND (1); before line 5. Without extending the table, any attempt to directly assign values would lead to errors. Secondly, the variable 'i' used in the loop should be properly declared. This can be done by adding i PLS_INTEGER; before line 3. Declaring 'i' ensures the scope and type of the iterator are correctly set, avoiding undeclared variable errors.
