Additionally, you can group on fields to calculate totals for each unique combination of values across the group fields. When Totals is selected, a new "Total" row appears in the query design. You can specify the type of calculation you want in that section: For this query, the result shows average Age, Weight and Cholesterol for patients by State and Gender. Crosstab Queries Crosstabs are a powerful analysis tool that lets you quickly see the relationship of data between two fields.

The view is a spreadsheet like display with unique values of one field as rows, unique values of another field as columns, and the summary of another field as the cells in the matrix.

For instance, with the previous example, a crosstab can clearly show the average Cholesterol between State rows and Sex columns: The easiest way to create a crosstab is to use the Crosstab Wizard.

When creating a new query, select Query Wizard and follow the Crosstab Query steps: Crosstab queries can also be manually created by selecting Crosstab from the Query menu and specifying the Row and Column Headings: Multi-table Queries To this point, all the queries shown were for one table only. Microsoft Access queries allow very sophisticated multi-table queries. Criteria and field selections can be from any of the query's tables. Linking tables on fields is done visually by dragging a line between the fields to link.

For our previous example, we may want to show the full name of each state rather than its abbreviation. With a State table that contains the abbreviation and full names, this can be easily performed: Notice the link on the [State] fields and the [Name] field from the States table in the query. To create multi-table queries, the Table row should be displayed.

Microsoft Access Query Tips and Techniques with SQL and VBA Code

This can be activated from the View Table Names menu. Even better, the default query options should set Show Table Names to Yes. There are several ways to join tables in a query. Another join includes retrieving all records from one table regardless of whether there are matches in the second table. These options can be selected by double clicking on the linking line and choose among the three options. Left Join Between Tables Here is an example of a query with a left join and the results.

No Joins Between Tables Queries with multiple tables do not even require a line between the tables. If no lines are specified, a record by record link is assumed. That is every record in the first table is linked to every record in the second table.

This is most useful when one of the tables only has one record. Finally, tables may be linked through an expression that establishes a partial match or match based on a range of values. Examples are shown later. Basing Queries on Other Queries So far, the queries presented are only based on tables. However, Microsoft Access lets you also base queries on other queries. This ability to filter and analyze data across several levels is extremely powerful.

The queries themselves behave identically whether the data comes from tables or queries. Basing queries on other queries can also simplify maintenance of your database by letting you create standard queries that other queries can use. This can be particularly useful in reports.

Of course, you need to be careful modifying the "core" queries.

Additionally, when generating reports in multi-user databases, make sure you don't use queries when you should be using temporary tables generated by Make Table and Append queries. Queries always retrieve the most current data. If you are printing many reports while others are modifying the data, and consistency between reports is important the numbers need to tieyou must create temporary tables with the data you need prior to printing.

You can then base your queries on those "static" tables. Percent of Total For a field, calculating the percent of each record to the total for an entire table is useful for determining the relative size of each group. This can be achieved by creating a summary query and using that in another query with the original table.

In this example, we use the Fortune table containing sales and profits data for large corporations; and two queries "Fortune Totals" and "Fortune PercentOfTotals". Here's how they work: Create a Query calculating the Totals This is a simple query that sums the values in the two fields: For clarity, the resulting fields are named [TotalSales] and [TotalProfits].

Create a Query with the Totals and the Original Table This is a simple select query that retrieves fields from the Fortune table and creates new fields for the Percent of Total calculations.

Notice the two tables are not linked with lines between them. They only interact in the Percent of Total calculations where the values in the calculated fields using TotalSales and TotalProfits as divisors: Run the Query Running the query provides the desired results: Percent of Total in Microsoft Access Reports Calculating percent of total in Microsoft Access reports is even simpler because queries don't need to be created.

The first step is to create a control with the summary total. The value can be the total for the entire report or just the group. Give the text box control a name e. You can then reference that control for the value of the total. Frequency Distributions Frequency distributions reveal the number of records that contain values within numeric ranges. By using the VBA function, Partition, you can group on that for intervals of identical widths.

In this example, we show how you can define your own groupings of different size ranges, give them your own label and sort the results in the order you expect. All without writing any code! Little dating a range or thing based on personality and maximum dating with sweet individuals.
