As you proceed, remember that many of the aggregate functions work only on data in fields set to a specific data type.
#USING ZOOM FOR GRANDTOTAL HOW TO#
The steps in the following sections explain how to add a Total row, use a totals query to sum data across groups, and how to use a crosstab query that subtotals data across groups and time intervals. For more information about using the other aggregate functions, see the section Aggregate function reference later in this article.įor more information about ways to use the other aggregate functions, see the article Display column totals in a datasheet. Note: The how-to sections in this document emphasize using the Sum function, but remember that you can use other aggregate functions in your Total rows and queries. For example, you can use a crosstab query to display sales totals for each city for the past three years, as the following table shows: Crosstab queries summarize your values and then group them by two sets of facts - one set down the side (row headings), and the other across the top (column headings). A crosstab query is a special type of query that displays its results in a grid that resembles an Excel worksheet. For example, if you want to subtotal all sales by city or by quarter, you use a totals query to group your records by the desired category and you then sum the sales figures.Ĭreate a crosstab query. A totals query calculates subtotals across groups of records a Total row calculates grand totals for one or more columns (fields) of data. The Total Row, a feature in Access, allows you to use an aggregate function in one or more columns of a query result set without having to change the design of your query.Ĭreate a totals query. Open your query in Datasheet view and add a Total row.
In addition, Access provides several ways to add Sum and other aggregate functions to a query. You sum data by adding the Sum function to your query, you count data by using the Count function, and so on. Access provides a variety of aggregate functions, including Sum, Count, Avg (for computing averages), Min and Max. Aggregate functions perform a calculation on a column of data and return a single value. You can sum a column of numbers in a query by using a type of function called an aggregate function. Sum data across multiple groups by using a crosstab query What do you want to do?Ĭalculate group totals by using a totals query In addition, this article explains how to use the Total Row, a feature in Access that you use to sum data without having to alter the design of your queries. This article also briefly explains how to use other aggregate functions, such as COUNT and AVG to count or average the values in a result set. This article explains how to use a type of function called an aggregate function to sum the data in a query result set.
