Eight-byte integers
The DataBlade®
API supports
the following data types for eight-byte integer values.
| DataBlade® API eight-byte integers | Description |
|---|---|
| mi_int8 | Signed eight-byte integer value |
| mi_unsigned_int8 | Unsigned eight-byte integer value |
| mi_bigint | Signed eight-byte integer value |
| mi_unsigned_bigint | Unsigned eight-byte integer value |
The DataBlade®
API ensures
that these integer data types are eight bytes on all computer architectures.
Use these integer data types to hold values for the following SQL
eight-byte integer data types:
- The SQL INT8 data type and the BIG INT data type can hold integer values in the range -9,223,372,036,854,775,807 - 9,223,372,036,854,775,807 [or -(263-1) - 263-1].
- The SQL SERIAL8 and BIGSERIAL data types hold eight-byte integer values that the database server automatically assigns when a value is inserted in the column.
The mi_int8 and mi_unsigned_int8 data types hold the internal (binary) format of an INT8 or SERIAL8 value. The mi_bigint and mi_unsigned_bigint data types hold the internal (binary) format of an BIGINT or BIGSERIAL value.
Values of the mi_int8, mi_unsigned_int8, mi_bigint, and mi_unsigned_bigint data types cannot fit into an MI_DATUM structure. They must be passed by reference within C UDRs.
All data types, including mi_int8, mi_unsigned_int8, mi_bigint, and mi_unsigned_bigint must be passed by reference within client LIBMI applications.
