VBA - working with data videos | Excel VBA Part 58.5 - SQL for Excel Files - Basic Criteria in Queries

Posted by Andrew Gould on 19 May 2021

This video explains how to add the Where clause to your SQL query to extract only the rows you want from an Excel file. You'll learn about the basics of adding criteria to the Where clause, including how to write basic logical tests and the range of available comparison operators. You'll also learn how to enter numbers, text and date values in your conditions, including the best date format to use. You'll learn how to combine conditions using the And and Or operators, and how to reverse the logic using the Not operator, including how to ensure multiple conditions are evaluated in the correct order by using brackets. You'll see how to use the special Like operator with wildcard characters for working with text columns. You'll also learn how to use the special In and Between operators to shorten longer criteria and make your SQL code more succinct. Finally, you'll learn how to use the Is Null and Is Not Null operators to find or ignore rows with missing values.
