Microsoft Access is a powerful database that is part of the Microsoft Office package, and by combining its user-friendly interface with the flexibility of SQL (Structured Query Language), you can unlock the full potential of your Access database. However, if you’re new to Access, it can be challenging to determine where to enter your SQL and what you can do with it.
Why Use SQL in Microsoft Access?
It gives you direct control over data, allowing you to retrieve, insert, update, or delete specific data. You can also use it to perform complex calculations, aggregations, and data filtering with ease.
SQL makes it possible to work with very large datasets that would be hard to manage with the graphical interface. You can also save your SQL scripts to use in the future or share them with others, allowing you to save even more time the more frequently you use them.
Steps to using SQL in Microsoft Access
1. Launch Microsoft Access and open an existing database or create a new one.
2. Click on the Create tab in the ribbon at the top.
3. Select Query Design from the Queries group.
4. In the Query Design window, look for the View button in the top-left corner.
5. Click the dropdown arrow and select SQL View, which will enter a blank SQL editor where you can input SQL commands.
6. After entering your commands, you can click Run at the top left of your screen, near where you selected SQL view, to execute them.
7. If your SQL command is something you might use in the future, click the Save button or press Ctrl+S and give it a descriptive name so it’s easy to find later.
SQL script examples

);
Script to insert data into a table:
INSERT INTO Employees (FirstName, LastName, HireDate, Salary)
VALUES ('John', 'Doe', #2021-01-15#, 50000);
Script to retrieve data from a table:

FROM Employees
WHERE Salary > 40000;

FAQ
Will SQL work in any database?
Yes, SQL is a database language that works with any common database. It is not exclusive to Microsoft Access. That said, some commands might differ slightly, and the steps you need to take to enter and run SQL might be different.
How is Access SQL different from standard SQL?
Access SQL is slightly simplified and has some unique syntax rules, such as:
Dates are enclosed in # symbols (e.g., #2023-01-01#).
The wildcard character is * (instead of % in standard SQL).
Text values are enclosed in single or double quotes (e.g., 'John' or "John").
Is SQL in Access case-sensitive?
SQL keywords like SELECT and WHERE are not case-sensitive in Access. However, table and field names may be case-sensitive depending on your database settings.
