I have an app that pulls data from a database. The data is then passed to a function that manipulates it and returns it as string. The returns from the database could be just about any date type and Nulls are possible. The problem is the code that calls the function can’t be changed to check for nulls. I have set up the function to accept a string as a parameter. This works for everything except nulls. Short of using a variant as the parameter, is there any other way to deal with these nulls?
