INT8

The INT8 data type stores whole numbers that can range in value from
–9,223,372,036,854,775,807 to 9,223,372,036,854,775,807 [or -(2⁶³-1) to 2⁶³-1], for 18 or 19 digits of precision. The number –9,223,372,036,854,775,808 is a reserved value that cannot be used. The INT8 data type is typically used to store large counts, quantities, and so on.

Dynamic Server stores INT8 data in internal format that can require up to 10 bytes of storage. Extended Parallel Server stores INT8 values as 8 bytes.

Arithmetic operations and sort comparisons are performed more efficiently on integer data than on floating-point or fixed-point decimal data, but INT8 cannot store data with absolute values beyond | 2⁶³-1 |. If a value exceeds the numeric range of INT8, the database server does not store the value.
