To extract the last word in a string

Hi

I am using BODS 14.1.1.210 

I would like to extract the last word in a string in BODS query. How can I achieve this when  I don't know how many words are present in a space delimited string.

Example

Input                                              Output    

My name is Tim                              Tim

Complicated                                    Complicated

there is a bird in the nest                 nest

Please let me know if there is a query function for this one.

Cheers!
