Data Types

A data type is a basic data attribute. Occupied storage space and allowed operations vary according to data types. Data is stored in tables in a database. Each column of a data table specifies a data type and data must be stored according to data types.

GaussDB supports implicit conversions between certain data types. For details, see PG_CAST.
