TechHelp Access, what is a query
Intro In this video, we will talk about what a query is in Microsoft Access. You will learn how queries help you view, sort, and filter data from your tables, making it easy to display specific information like customers from a certain state. We will also discuss how queries can be saved for repeated use, and mention that queries can be used to modify data, though we will cover those advanced options in later lessons.Transcript What is a query in Microsoft Access?
The data in your tables might not be stored in any particular order. You may have hundreds of thousands of records in your table, and the boss says to you, "I want to see a list of only customers from Florida sorted by last name." That is what a query is used for.
A query can be used to display data in different ways. You can sort your data or apply criteria to only a few specific fields. Queries can be saved and used later, so you do not have to keep redesigning them. Someone with little Access knowledge can run your query simply by double-clicking on it.
Queries can also be used to modify data, add records, delete records, or edit records. We will learn more about these types of queries, called action queries, in our expert classes.
For today, just keep in mind that queries let you view the data in your tables in different ways.

Often, the information in your tables is not organized in any particular order. You might have a huge number of records, and someone might ask to see only a certain group of them. For instance, your boss may request a list of customers from Florida, sorted by their last name. This is a perfect situation where a query becomes essential.
With a query, you can view your data in many different ways. Queries let you sort your records and filter them based on specific criteria, so you can focus on just the information you need. Once you've created a query, you do not need to design it all over again each time you want to use it. Simply save the query, and anyone can run it later by opening it, even without much Access experience.
Queries are not limited to just viewing your data. They can also be designed to make changes. You can add new records, update existing ones, or even remove records from your tables. These types of queries are known as action queries, and we will explore those in detail in the more advanced lessons.
For now, remember that queries are a powerful tool that allow you to look at your table data from different perspectives and meet specific needs quickly.
