Access Create a Query.Free Access Tutorial at GCFGlobal



 

Now we get to design our query. We'll keep it simple, and create a query that returns all albums from Iron Maiden. We specified criteria for the Artists. ArtistName field but we chose not to display that field in the results.

If we had, Iron Maiden would be repeated five times — once for every record. You can switch between the query design and the results by clicking this button just as you do when switching between Design View and Datasheet View when working with tables. To use this option, click the little "down arrow" below the word View. The result being the single record. Was this reply helpful? Yes No. Sorry this didn't help. Choose where you want to search below Search Search the Community.

However, you could easily run a query to find the name and phone number of every customer who's made a purchase within the past week. A well-designed query can give information you might not be able to find out just by examining the data in your tables. When you run a query, the results are presented to you in a table, but when you design one you use a different view. This is called Query Design view , and it lets you see how your query is put together.

Click the buttons in the interactive below to learn how to navigate the Query Design view. Click the View drop-down arrow to switch to another view of your query. In most cases, you will only need to use two main views: Datasheet view and Design view. Datasheet view lets you view your query results in the form of a table.

Design view , featured here, allows you to view and modify the design of your query. After you have designed your query, click the Run command to view the results of the query in a table. All of the tables you choose to include in your query will appear as small windows in the Object Relationship pane. Each window contains a list of every available field within that table. The first row of the design grid contains the names of the fields included in the query.

Directly beneath each field name is the name of the table that field belongs to. In the Order Details table, double-click Product ID to add this field to the first column of the query design grid. In the second column of the grid, right-click the Field row, and then click Zoom on the shortcut menu. The query runs, and then displays a list of products and subtotals, per order. When you use tables to record transactions or store regularly occurring numeric data, it is useful to be able to review that data in aggregate, such as sums or averages.

In Access, you can add a Totals row to a datasheet. Total row is a row at the bottom of the datasheet that can display a running total or other aggregate value. Run the Product Subtotals query you created earlier, and leave the results open in Datasheet view. On the Home tab, click Totals.

A new row appears at the bottom of the datasheet, with the word Total in the first column. Click the arrow to view the available aggregate functions. Because the column contains text data, there are only two choices: None and Count. Select Count. The content of the cell changes from Total to a count of the column values. Click the arrow, and then click Sum.

The field displays a sum of the column values. Now suppose that you want to review product subtotals, but you also want to aggregate by month, so that each row shows subtotals for a product, and each column shows product subtotals for a month.

To show subtotals for a product and to show product subtotals for a month, use a crosstab query. Note: A crosstab query cannot be displayed in an Access web app. You can modify the Product Subtotals query again so that the query returns rows of product subtotals and columns of monthly subtotals.

On the Design tab, in the Query Type group, click Crosstab. In the design grid, the Show row is hidden, and the Crosstab row is displayed. In the third column of the design grid, right-click the Field row, and then click Zoom on the shortcut menu. The Zoom box opens. In the Crosstab row, select the following values from the drop-down list: Row Heading for the first column, Value for the second column, and Column Heading for the third column.

The query runs, and then displays product subtotals, aggregated by month. For more information about crosstab queries, see Make summary data easier to read by using a crosstab query. Note: A make-table query is not available in Access web apps. For example, suppose that you want to send data for Chicago orders to a Chicago business partner who uses Access to prepare reports. Instead of sending all your order data, you want to restrict the data that you send to data specific to Chicago orders.

You can build a select query that contains Chicago order data, and then use the select query to create the new table by using the following procedure:. Note: If you see a message beneath the Ribbon about enabling the database, click Enable content.

If your database is already in a trusted location, you will not see the Message Bar. In the Ship City column of the design grid, clear the box in the Show row. In the Criteria row, type 'Chicago' include the single quotation marks. Verify the query results before you use them to create the table. In the confirmation dialog box, click Yes , and see the new table displayed in the Navigation Pane.

Note: If there is already a table with the same name that you specified, Access deletes that table before running the query.

For more information about using make table queries, see Create a make table query. You can use an append query to retrieve data from one or more tables and add that data to another table. Note: Append query is not available in Access web apps. For example, suppose that you created a table to share with a Chicago business associate, but you realize that the associate also works with clients in the Milwaukee area. You want to add rows that contain Milwaukee area data to the table before you share the table with your associate.

You can add Milwaukee area data to the Chicago Orders table by using the following procedure:.
