Data Types

Module Description

The DB Interface Module normalizes data types between applications and vendor databases. In the process, it uses several kinds of data types:

• the primitive C++ data types
• data types from the Essential Tools Module, including RWCString, RWWString, RWBasicUString, RWDate, RWDateTime, RWDecimalPortable, and RWTime.
• data types it defines

The data types defined by the DB Interface Module are listed in this group. See the DB Interface Module User's Guide for more information on the data model of the DB Interface Module.

Classes
class	RWDBBlob
	Stores Binary Large Objects (Blobs) and includes relevant accessors. More...
class	RWDBDateTime
	Deprecated. Represents a date and time stored as the number of milliseconds. More...
class	RWDBDuration
	Represents a time span in number of seconds. More...
