Hi...
How can i call a c function for e.g say rounding decimals in Netezza.As it is possible in Netezza with a external C routine but don't the way to proceed.Can anyone please help me out.....??

I'm not familiar with Netezza, but if it's an external application with command line functionality, or an application that exposes an API, or a web service, you can certainly send input and retrieve output using pipes. However, that's a rather platform-specific solution, so it would be best if you gave more details about Netezza and the compiler/OS you're working with.

I have worked with Neteeza before . I think you will find the information that you are looking for in the manual
