Data Types

Updated at: Sep 17, 2021 GMT+08:00

A data type refers to a value set and an operation set defined on the value set. A GaussDB(DWS) database consists of tables, each of which is defined by its own columns. Each column corresponds to a data type. GaussDB(DWS) uses corresponding functions to perform operations on data based on data types. For example, GaussDB(DWS) can perform addition, subtraction, multiplication, and division operations on data of numeric values.
