VBA - working with data videos | Excel VBA Part 58.9 - SQL for Excel Files - Nulls in Expressions

Posted by Andrew Gould on 03 June 2021

In this video you'll learn how to work with nulls in your SQL queries. You'll see how to use the IS NULL expression and IsNull function to check for the existence of nulls and how to use the IIf and Switch functions to replace nulls with other values. You'll also see what happens when a null is involved in a calculation and how to make sure that the calculation returns a non-null result.

This video has the following accompanying files:

File name Type Description
