Getting Help from the Expression Builder
The Expression Builder is a helpful tool for building expressions in your queries, as well as in many other situations in Access. To invoke the Expression Builder, click in the Field cell of your query design grid and then click Builder on the Ribbon. The Expression Builder is divided into three columns. The first column shows the objects in the database. After selecting an element in the left column, select the elements you want to paste from the middle and right columns.Functions are selected in the left column. Within Functions, both user-defined and built-in functions are listed; here, the Functions object is expanded with Built-In Functions selected. In the center column, Date/Time is selected. After you select Date/Time, all the built-in date and time functions appear in the right column. If you double-click a particular function—in this case, the DatePart function—the function and its parameters are placed in the text box at the top of the Expression Builder window. Notice that the DatePart function has four parameters: interval, date, firstweekday, and firstweek. If you know what needs to go into each of these parameters, you can simply replace the parameter placemarkers with your own values. If you need more information, you can invoke help on the selected function and learn more about the required parameters. For example you could fill in two parameters: the interval and the name of the field being evaluated. After you click OK, the expression is placed in the Field cell of the query.
Summarizing Data with Totals Queries
By using Totals queries, you can easily summarize numeric data. You can use Totals queries to calculate the Sum, Average, Count, Minimum, Maximum, and other types of summary calculations for the data in your query result. These queries let you calculate one value for all the records in your query result or group the calculations as desired. For example, you could determine the total sales for every record in the query result or you could output the total sales by country and city. You could also calculate the total, average, minimum, and maximum sales amounts for all customers in the United States. The possibilities are endless.
To create a Totals query, follow these steps:
1. Add to the query design grid the fields or expressions you want to summarize. It's important that you add the fields in the order in which you want them grouped. For example, you could create a query grouped by country and then city.
2. Click Totals on the ribbon to add a Total row to the query. By default, each field in the query has Group By in the Total row.
3. Click in the Total row on the query design grid.
4. Open the combo box and choose the calculation you want.
5. Leave Group By in the Total cell of any fields you want to group by. Remember to place the fields in the order in which you want them grouped. For example, if you want the records grouped by country and then by sales representative, you must place the Country/Region field to the left of the Employee ID field on the query design grid. On the other hand, if you want records grouped by Employee ID and then by country, you must place the Employee ID field to the left of the Country field on the query design grid.
6. Add the criteria you want to the query.
