What is the number of rows returned by an SQL query on the below EMP table?
$\begin{array}{|c|c|c|} \hline \text{eno} & \text{ename} & \text{manager} \\ \hline 1 & A & \text{Null} \\ \hline 2 & B & \text{Null} \\ \hline 3 & C & \text{Null} \\ \hline 4 & D & \text{Null} \\ \hline \end{array}$
SELECT * FROM EMP where manager IN (NULL, NULL,NULL);
- It will throw an error.
- Three rows are selected.
- No rows are selected.
- One row is selected.
