Passing value of a column into a stored procedure

I want to generate data for two columns that are dependent upon one another. (i.e. value of column B is depending on the value generated for Column A) This works fine when using IronPython. However, I want to be able to use SQL Generator. I'd like to be able to pass the value of column A into a stored procedure and then have the stored procedure return a value for column B that makes sense. Is there a way to do this
