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.
Tutorial exercise 2: Creating distinct data types and castsThis exercise demonstrates how to create distinct data types and the casts that convert them. This exercise consists of 14 steps. It takes approximately one hour to complete.

About this task

Although you are not setting breakpoints and debugging this DataBlade® module, using the DBDK Visual C++ Add-In and the unit test files is the easiest way to run SQL statements for your DataBlade module.

To edit the Setup.sql file:

Procedure

In Visual C++, open the Setup.sql file under the Test Files node in the File view. If Visual C++ indicates that the file does not exist, click Yes to create it.
Replace the contents of this file with the SQL statements in the mercury.txt file.
Save the changes to Setup.sql.
