Extending Informix®Beyond standard relational database objects, HCL Informix® can be extended to handle specialized data types, access methods, routines, and other objects. Informix® includes many built-in extensions that are fully integrated in the database server. Informix® also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for Informix®.
Creating extensionsYou can create user-defined data types, routines, access methods, and other database objects to suit your needs. You can use application programming interfaces to write user-defined routines and applications that access data in Informix® databases.
DataBlade® Developers KitThe DataBlade® Developers Kit (DBDK) guides contain information about the tools you can use to develop and package DataBlade® modules, which extend the functionality of HCL Informix® databases.
DBDK InfoShelfThe DataBlade® Developers Kit InfoShelf is designed to help you work with BladeSmith.
DataBlade® Developers Kit TutorialThe Tutorial is a set of exercises that demonstrate how to create extensions to HCL Informix® and package them as DataBlade® modules by using DBDK. Support for DataBlade Developers Kit (DBDK) is removed starting Informix Server 14.10.xC6.

Text file import and export functions

Text file import and export functions

Text file import and export functions transfer the text representation of the opaque data type to and from a flat file.

Text file import and export functions enable bulk copy for opaque data types. When you copy data from a file into a database with PLOAD or the DB-Access LOAD command, the server calls a text file import function to convert the incoming value to the server binary format. When data is copied out of the database into an external file, the server calls a text file export function to convert the value from server binary format to text file format.

BladeSmith generates the complete code for these functions.

See the Informix® DataBlade® Developers Kit User's Guide for more information.
