Signed SMALLINT values range from –2^15 (2^15 represents 2 raised to the 15th power) to 2^15 – 1, which is –32768 to 32767.
The unsigned SMALLINT value range is 0 to 2^16 – 1, that is, 0 to 65535. INT is 4-byte data, with a value range of -2^31 - 2^31. Therefore, taking into account the maximum data range, the smallint type is preferred.
