Join Adam Wilbert for an in-depth discussion in this video Nesting IIf functions, part of Access 2010: Queries in Depth.
In the last movie, we took a look at how we can use a conditional statement to…return one of two values.…We would supply an expression, and depending on whether that expression is true…or false, we would get a branching decision tree.…Now we can nest conditional statements together, so instead of a true part, we…might evaluate to a second IIf statement, or instead of false, we might go to…a second or third IIf statement that way.…Now if we nest multiple conditional statements together, we can get a branching…decision-making tree.…This will function much like a flowchart where we'll start at the top and…depending if the statement is true or false, we'll move left or right, we'll…evaluate with a second expression, and again move left and right from there.…
At the end of the chain, we can have four expressions returned, four different…values depending on how it flowed through the chart.…Let's go ahead and take a look at this concept in Access and we'll apply it to…a sales tax calculation.…So let's create a query that decides whether or not we should be charging sales…
