Ways to use expressions. Examples of expressions. Components of expressions. Comparison of Access expressions and Excel formulas.

Think of it this way: when you want Access to do something, you have to speak its language. For example, suppose you want to tell Access "Look at the BirthDate field in the Customers table and tell me the year of the customer's birth. This expression consists of the DatePart function and two argument values: "yyyy" and [Customers]! In this case, the first two arguments are used. Calculate values that do not exist directly in your data. You can calculate values in fields in tables and queries, and you can also calculate values in controls on forms and reports.

Define a default value for a table field or for a control on a form or report. These default values appear whenever you open a table, form, or report.

Create a validation rule to control what values users can enter in a field or control. Define query criteria to limit results to a desired subset. One of the most common ways to use expressions in Access is to calculate values that don't exist directly in your data. A column in a table or query that results from such a calculation is called a calculated field. You can create a calculated field that combines two or more table fields.

For example, many tables store first and last names in separate fields. If you want to combine those first and last names and then display them in a single field, you can create a calculated field in the table or in a query:.

You can also use expressions in Access to provide a default value for a field in a table or for a control. For example, to set the default value for a date field to the current date, in the Default Value property box for that field, you type:.

In addition, you can use an expression to set a validation rule. For example, you can use a validation rule in a control or table field to require that the date that is entered is greater than or equal to the current date. In that case, you set the value in the Validation Rule property box to:. Finally, you can use an expression to set criteria for a query. Microsoft Expression Web is compatible with all the current standards Vote 1 2 3 4 5 6 7 8 9 Requirements and additional information:.

This download requires. NET Framework 4. Creates a field called YearHired, and then uses the DatePart function to display the year each employee was hired.

Creates a field called MinusThirty, and then uses the Date function to display the date 30 days prior to the current date. You often see these functions for example, Sum, Count, and Avg referred to as aggregate functions.

In addition to aggregate functions, Access also provides "domain" aggregate functions that you use to sum or count values selectively. For example, you can count only the values within a certain range or look up a value from another table.

To calculate totals, you will often need to create a totals query. For example, to summarize by group, you need to use a Totals query. To enable a Totals query from the query design grid, click Totals on the View menu.

Creates a field called RowCount, and then uses the Count function to count the number of records in the query, including records with null blank fields.

Creates a field called FreightPercentage, and then calculates the percentage of freight charges in each subtotal by dividing the sum of the values in the Freight field by the sum of the values in the Subtotal field. This example uses the Sum function. You must use this expression with a Totals query. Creates a field called AverageFreight, and then uses the DAvg function to calculate the average freight on all orders combined in a Totals query.

The expressions shown here work with fields with potentially missing information, such as those containing null unknown or undefined values. You frequently encounter null values, such as an unknown price for a new product or a value that a coworker forgot to add to an order. The ability to find and process null values can be a critical part of database operations, and the expressions in the following table demonstrate some common ways to deal with null values. Creates a field called CurrentCountryRegion, and then uses the IIf and IsNull functions to display an empty string in that field when the CountryRegion field contains a null value; otherwise, it displays the contents of the CountryRegion field.

Creates a field called LeadTime, and then uses the IIf and IsNull functions to display the message "Check for a missing date" if the value in either the RequiredDate field or the ShippedDate field is null; otherwise, it displays the date difference. Creates a field called SixMonthSales, and then displays the total of the values in the Qtr1Sales and Qtr2Sales fields by first using the Nz function to convert any null values to zero.

You can use a nested query, also called a subquery, to create a calculated field. The expression in the following table is one example of a calculated field that results from a subquery. The sample expressions in this table demonstrate criteria that match whole or partial text values. Uses the Or operator to display orders shipped to London or Hedge End. Uses the In operator to display orders shipped to Canada or the UK.

Displays orders shipped to companies whose names start with the letters N through Z. Uses the Right function to display orders with ProductCode values that end in Displays orders shipped to customers whose names start with the letter S. The expressions in the following table demonstrate the use of dates and related functions in criteria expressions. For more information about entering and using date values, see the article Format a date and time field.

Uses the Between And operator and the DateAdd and Date functions to display orders required between today's date and three months from today's date. Uses the Year and Month functions and the And operator to display orders for the current year and month.

And operator to display orders shipped no earlier than 5-Jan and no later than Jan And operator to display orders required between today's date and three months from today's date. The expressions in the following table work with fields that have potentially missing information — those that might contain a null value or a zero-length string.

A null value represents the absence of information; it does not represent a zero or any value at all. Access supports this idea of missing information because the concept is vital to the integrity of a database. In the real world, information is often missing, even if only temporarily for example, the as-yet undetermined price for a new product.

Therefore, a database that models a real world entity, such as a business, must be able to record information as missing. You can use the IsNull function to determine if a field or control contains a null value, and you can use the Nz function to convert a null value to zero.

Displays orders for customers who don't have a fax machine, indicated by a zero-length string value in the Fax field instead of a null missing value. The Like operator provides a great deal of flexibility when you are trying to match rows that follow a pattern, because you can use Like with wildcard characters and define patterns for Access to match. For more information, see the article Like Operator.

Finds all records in the ShipName field that include "Maison" in the first part of the value and a five-letter string in which the first four letters are "Dewe" and the last letter is unknown. You use an SQL or domain aggregate function when you need to sum, count, or average values selectively. For example, you might want to count only those values that fall within a certain range, or that evaluate to Yes. At other times, you might need to look up a value from another table so that you can display it.

The sample expressions in the following table use the domain aggregate functions to perform a calculation on a set of values, and use the result as the query criteria. Uses the DStDev and DAvg functions to display all orders for which the freight cost rose above the mean plus the standard deviation for freight cost. Uses the DAvg function to display products ordered in quantities above the average order quantity. You use a subquery, also called a nested query, to calculate a value for use as a criterion.

The sample expressions in the following table match rows based on the results returned by a subquery. Salary of every sales representative whose salary is higher than that of all employees with "Manager" or "Vice President" in their titles.

You use an update query to modify the data in one or more existing fields in a database. For example, you can replace values or delete them entirely. This table demonstrates some ways to use expressions in update queries. You use these expressions in the Update To row in the query design grid for the field that you want to update.

For more information about creating update queries, see the article Create and run an update query. Every query that you create in query Design view can also be expressed by using SQL. The following table shows sample SQL statements that employ an expression.

Calculates the average extended price for orders for which the value in the ExtendedPrice field is more than , and displays it in a field named Average Extended Price. In a field named CountOfProductID, displays the total number of products for categories with more than 10 products. The two most common ways to use expressions in tables are to assign a default value and to create a validation rule. When you design a database, you might want to assign a default value to a field or control.

Access then supplies the default value when a new record containing the field is created or when an object that contains the control is created.
