Individual Rogue Wave® DB Link type definitions are provided in the Reference Manual.

The minimal set of ANSI database data types are translated to the same types for all supported RDBMSs. The data types that are handled by Rogue Wave DB Link are the same for input and for output. The database system input and output types are mapped to Rogue Wave DB Link types according to tables that show which Rogue Wave DB Link type is used to retrieve the database data.

A one-to-one correspondence between database data types and Rogue Wave DB Link types cannot be established. The Rogue Wave DB Link principle for mapping is economy—that is, Rogue Wave DB Link defines a minimal set of data types to which database types are converted. This does not prevent Rogue Wave DB Link from converting all database data types for each supported RDBMS.
