Here are some examples of the integer data types. When deciding on an integer for a column, variable, parameter or expression it is a wise choice to choose the most efficient data type based off of size and usage.
TINY INTEGER – The tiny integer data type allows for whole numbers between 0 and 255 and only uses 1 byte of data.
SMALL INTEGER – The small integer data type allows for a whole number between -32678 to a positive value of 32767 and will consume 2 bytes of data.
REGULAR INTEGER –The regular integer data type allows for a whole number between -2147483648 to a positive value 2147483647 and will consume 4 bytes of data.
BIG INTEGER- The big integer data type allows for a whole number between -9 quintillion to a value of positive 9 quintillion and will consume 8 bytes of data.
