Simple Access queries show detail, line by line records but summarising your data requires the Groups and Totals query. However, how you apply criteria may have an effect if you do not follow the rules. Using the Access ‘Where’ clause can be a better way to apply criteria to your query.
This video tutorial (less than 5 minutes) will explain the use for an Access Where clause query instead of using the ‘Group By’ option…
Access Where Clause: The Difference Between Group By and the Access Where clause
To clarify and confirm, the Access Where clause cannot be seen (or is visible) to the output of an Access query unlike the ‘Group By’ option which affects data distribution.
This is a useful attribute especially when handling complex criteria that sits in the background and is processed first before the output is called which is what the ‘Where’ clause means.
