6. Close and save query as Inventory Query.

Queries with Multiple Values

A Parameter Query is one that prompts the user for the query criteria for retrieving records.
These criteria can be single-valued or multi-valued. In addition, the criteria can be entered
as absolute values or as wildcards. Assume that a company has a calendar year-end. We
can query for all sales greater than $650.00 between January 1, 2006 and December 31,
2006. We could also create the query by using wildcards for the dates. In this case, the
query would substitute variables such as "BeginDate" and "BSDate." In this parameter
query, Access then prompts the user for the appropriate values.
Assume that Dan Tragg wants to view his Cash Receipts for October. We can easily
create a query that will isolate those cash receipts.

1. Click on the Queries object. Click on Create query in design view. Click on the
Cash Receipt Table to add it to the upper part of the Query window. Hold down the Ctrl
key and click on the Cash Receipt Sale Table and click on Add. Close the Show Table
window.
2. Drag the CashReceiptID and the CRDate fields from the Cash Receipt Table
into the first two columns of the design grid. Drag the AmountApplied field from the
Cash Receipt Sale Table into the third column of the design grid.
3. Click on the Totals icon. Pull down the menu under the Total property for the
CRDate. Note that there are various mathematical functions (including Sum and Average)
that we could choose here. However, these are not appropriate for a date field. Scroll down
to the bottom of the menu. The "Where" function will allow us to set the criteria for the
date. Change the Total property for the CRDate field to "Where."
4. In the Criteria property of the CRDate field, type Between [BeginDate] and
[EndDate].
