SSIS Derived Column IIF/IF Expression

This is for my memory, but I figure if I have a hard time remembering, maybe someone else will...

For those of you who are trying to remember how to do IF/IIF functionality in the SSIS Derived Column control:

({comparison} ? {truepart} : {falsepart})

So, if I want to evaluate the similarity from a fuzzy lookup, it would look like this:

(_Similarity > .78 ? ID : "")

Maybe someday Microsoft will standardize all of the expression languages in their BI tools!
