What happens when rows are found using a FETCH statement ?

  1. It causes the cursor to close

  2. It loads the current row values into variables

  3. It causes the cursor to open

  4. It creates the variables to load the values


Correct Option: B
Explanation:

When rows are found using a FETCH statement in SQL, it loads the current row values into variables.

Option B is the correct answer. The FETCH statement is used to retrieve rows from a cursor, and each time it is executed, it fetches the next row from the cursor result set and assigns the values to the specified variables. This allows us to work with the data retrieved from the cursor.

Here is a breakdown of the other options:

A. It causes the cursor to close: This option is incorrect. The FETCH statement does not close the cursor; it only retrieves the rows. The cursor can be closed explicitly using the CLOSE statement.

C. It causes the cursor to open: This option is incorrect. The FETCH statement is used after the cursor has been declared and opened. It does not open the cursor itself.

D. It creates the variables to load the values: This option is incorrect. The variables to hold the row values need to be declared before the FETCH statement is executed. The FETCH statement does not create the variables, but rather assigns the retrieved values to the existing variables.

Therefore, the correct answer is B. It loads the current row values into variables.
