Exercise 3: Creating Distinct Data Types and Casts, continued

The support functions for the decimal to temperature cast and the integer to temperature cast have the same C function name: temperatureCast(). SQL allows routines to have the same name as long as they have different parameters, but ANSI C requires unique routine names. Therefore, BladeSmith does not generate source code until you have made these names unique.

To edit the C function name, double-click the support routine that appears under the cast when you expand the hierarchy in the BladeSmith project window. The Properties dialog box appears.

In the Properties dialog box, click the Language tab, and then take the following actions:

• For the decimal to temperature cast, type DecToTemp for the C routine name and click Apply and then OK.
• For the integer to temperature cast, type IntToTemp for the C routine name and click Apply and then OK.

(The default C routine names for the CTemp to FTemp cast and the FTemp to CTemp cast do not conflict with other routines, so they do not need to be changed.)
