You create a query in Access by using the Query Design view. This view allows you to visually build a query by selecting tables and fields, and then specifying the criteria for the data you want to retrieve.
Here's how to create a query in Access:
- Open Access and navigate to the database where you want to create the query.
- Click the "Create" tab and select "Query Design" in the "Other" group.
- Select the tables you want to include in your query by clicking the "Add Table" button.
- Double-click the fields you want to include from each table. These fields will appear in the "Field" row of the query design grid.
- Add criteria to filter the data. You can do this by typing criteria in the "Criteria" row of the query design grid.
- Run the query by clicking the "Run" button.
Here are some examples of criteria you can use:
- Equal to:
= - Not equal to:
<> - Greater than:
> - Less than:
< - Greater than or equal to:
>= - Less than or equal to:
<= - Like:
Like "text*"(matches any text starting with "text") - Is Null:
Is Null(finds records where a field is blank)
You can also use AND and OR operators to combine multiple criteria.
For instance, if you want to find all customers in the "Northwind" database who are located in the "USA" and have a "ContactName" that starts with "A", you would use the following criteria:
- Country:
="USA" - ContactName:
Like "A*"
By combining tables, fields, and criteria, you can create powerful queries that extract meaningful information from your database.
