Answer: C, E, F
Explanation:
Since EMPLOYEE_ID column is used as primary key, it cannot be NULL, so only INSERT statements in C, E
and F are correct. You can insert the row with NULL LAST_NAME as in answer C, or only the row with
EMPLOYEE_ID as in answer E, or the row with empty LAST_NAME column.
Incorrect Answers
A: This answer is incorrect because a primary key cannot be NULL.
B: INSERT statement does not contain primary key value at all, so this answer needs to be eliminated as correct
one.
D: This statement shows incorrect order of columns of row which needs to be inserted into the table.
