You have a column that will only contain values from 0 to 256. What is the most economical data type to be used for the column?

CORRECT ANSWER : SMALLINT

Discussion Board
SQL SERVER

Correct Answer: B. SMALLINT

Explanation:

- In the above question, we are given that a column contains values from 0 to 256, so the correct answer is SMALLINT, because a SMALLINT data type uses only 2 bytes of data and can store values from -32,768 to 32,767.

- A TINYINT data type cannot be used because the maximum value it can hold is 0 to 255 and it has 1 byte storage capacity.

- Although an Integer data type can be used, SMALLINT will use only 2 bytes compared to Integer's 4 bytes, VARHCAR (3) will use 3 3 bytes while DECIMAL.
