How many bytes of storage does a BIGINT data type hold in MySQL?

A1 byte

B3 bytes

C4 bytes

D8 bytes

Show Suggested Answer

Suggested Answer: D

In MySQL, the BIGINT data type is a 64-bit integer that requires 8 bytes (64 bits) of storage. It is used to store large numerical values beyond the range of INT (4 bytes).

Option A (Incorrect): 1 byte corresponds to TINYINT, which can store values from -128 to 127.

Option B (Incorrect): 3 bytes is not a standard integer storage size in MySQL.

Option C (Incorrect): 4 bytes corresponds to INT, which has a range of -2,147,483,648 to 2,147,483,647.

Option D (Correct): BIGINT takes 8 bytes and supports a massive range of numbers from -2^63 to 2^63 -1.

Haha, 1 byte for a BIGINT? What is this, a database for ants?

D, no doubt. Anything less than 8 bytes would be a "TINYINT" at best.

I can't recall exactly, but I thought BIGINT was 4 bytes. I need to double-check my notes on data types.

I’m pretty confident that BIGINT is 8 bytes. I remember it being the same size as a double in some contexts.

I'm a bit confused on the exact size of BIGINT. I know it's a larger integer type, but I can't recall the specific number of bytes. I'll have to guess and go with C.

D) 8 bytes is the correct answer. That's the standard size for a BIGINT in MySQL.

Okay, let me think this through step-by-step. BIGINT is a larger integer type than INT, which is 4 bytes. So it's likely either 8 bytes or 16 bytes. I'll go with D to be safe.
