Allow Zero Length. The Difference Between Null and Zero Length String. Indicate No Middle Name.

Allow Zero Length. The Difference Between Null and Zero Length String. Indicate No Middle Name. In this Microsoft Access video, we're going to learn about Zero Length Strings, the Allow Zero Length property, how a ZLS is different from a Null value, how to set all of this up in our database, and most importantly how to use them each properly. Simon from Cleveland, Ohio (a Platinum Member) asks: I'm confused. What's the difference between a Null value and a Zero Length String? Silver Members and up get access to an Extended Cut of this video. Members will learn how to use the format property to display "NULL" or (None) and in color. We'll learn about a problem with DLookup and how it doesn't work properly with zero length strings. I'll share my DLookupZLS function which does work with ZLS. We'll see how short & long text fields handle ZLS differently. We'll learn about different combinations of the Allow Zero Length and Required properties. And we'll learn about two more possible values: Empty and Nothing. This Extended Cut is jam packed with goodies, folks.
