SQL programmingYou can use the HCL OneDB™ implementation of the SQL language to develop applications for HCL OneDB™ database servers.
Guide to SQL: ReferenceThe HCL OneDB™ Guide to SQL: Reference contains the reference information for the system catalog tables, data types, and environment variables of the HCL OneDB™ dialect of the SQL language, as implemented in HCL OneDB™. These topics also include information about the stores_demo, sales_demo, and superstore_demo databases that are included with HCL OneDB™.
Data typesEvery column in a table in a database is assigned a data type. The data type precisely defines the kinds of values that you can store in that column.
Description of Data Types
INT8The 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.

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.

HCL OneDB™ stores INT8 data in internal format that can require up to 10 bytes of storage.

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.
