Tutorial exercise 1: Creating a simple user-defined routine

This exercise demonstrates how to use the tools of the -- BladeSmith and the DBDK Visual C++ Add-In--to create a DataBlade® module with a user-defined routine and to debug it.

About this task

The AddInts DataBlade® module has one function, AddIntegers(), which adds two integers and returns the result.

You follow these basic steps to create the AddInts DataBlade® module:

Procedure

  1. Use BladeSmith to create the AddInts DataBlade® module project.
  2. Use BladeSmith to create the AddIntegers() function.
  3. Use BladeSmith to generate the DataBlade® module code.
  4. Create a test database.
  5. Add code for the AddInts() function to the code generated by BladeSmith.
  6. Compile and install your source code by using Microsoft™ Visual C++.
  7. Set a breakpoint for the AddInts() function.
  8. Edit the AddInts.sql unit test file.
  9. Click the Debug DataBlade® Module button on the add-in toolbar to start debugging
