MS-Access Paremeter Queries
Is it possible to create a parameter query, where if the parameter input box is left blank will return all of the records? This article details how, if you design your query using the following criteria, you will be able to query by either a specific value, or leave the parameter box empty to return all of the records: In the following example, we would like to add criteria to allow us to query for a Salesperson by region, but may also like to view all records as well.

Make a query ask for input
When you want a query to ask for input every time that you run it, you can create a parameter query (parameter query: A query in which a user interactively specifies one or more criteria values. A parameter query is not a separate kind of query; rather, it extends the flexibility of a query.). You can also create a form to collect parameter values. Using a form, you can: * Use data-type-specific controls * Enable the persistence of parameter values * Provide combo box controls (so that you can pick a value from a list, instead of typing it) * Use other controls that are available in forms This article provides an overview of parameters, explains how to use parameters in queries, and how to use forms to enhance your use of parameters.

Dynamic queries using parameters
A parameter query is a query in which the criteria for selecting records are determined when the query is executed rather than when the query is designed. Learning objectives: understand the way in which parameters can be used to create flexible queries; prompt the user to enter parameter values; create a query whose results depend on a value on a form.

Create parameter queries that prompt users for input
A Microsoft Access parameter query is useful when you perform the same type of query often, but the values that you search for change. If you're familiar with the basic select query, learn how to turn it into a parameter query. After completing this course you will be able to: 1) Understand when and how to use parameter queries. 2) Set up and run a parameter query that prompts you for the data you want to find. 3) Set up a parameter query that retrieves all the data between two values. (Microsoft Office Access 2003)

Examples of query criteria
When you want to limit the results of a query based on the values in a field, you use query criteria. A query criterion is an expression that Access compares to query field values to determine whether to include the record that contains each value. In this topic: * Introduction to query criteria * Criteria for Text, Memo, and Hyperlink fields * Criteria for Number, Currency, and AutoNumber fields * Criteria for Date/Time fields * Criteria for other fields

Plan for Null Responses in Your Parameter Queries
Parameter queries in your database are a favourite with many users because they're efficient, easy to create, and they offer a dynamic solution when you want to query the same field for different criteria. For the most part, parameter queries work great until you decide not to limit the results of the query. For instance, suppose you want to return all of the records in a table. If you ignore the parameter request by entering nothing in response to the prompt, Microsoft Access doesn't return any records. In this article, we'll show you a simple way to avoid this behaviour.

MS Access 2000 parameter queries
Can anyone help me with a problem I'm having running a parameter query in Access 2000 ? I have a table that has a date/time field that I need to query, based on user input. I want the user to be able to select a date and retrieve all the items received on that day. Problem is if I use the notation =[Date?] in the criteria box in the query design view, it returns no results, even though there are records that should be returned. What is the correct syntax I should be using ? If anyone can point me in the direction of a tutorial I'd be grateful.

The Query Lost My Records!
Nulls in Criteria: You wish to mail two different messages - one to your WA friends and another to those in other states. You create two queries: one where the Criteria line under State reads WA , and a second query where the Criteria line reads Not "WA" . You could think this would take care of all cases. It doesn't!

Creating a Delete Query in Microsoft Access
A Microsoft Access delete query deletes records from a single database table or database tables. Of all of the different action queries available in Microsoft Access (Append Queries, Update Queries, Make-Table Queries and Delete Queries) the delete query is one of the most dangerous.

As with the other types of action queries, the delete query will work with a group of records that meet a specified criteria that you apply. You can use the delete query to remove all records or only records that meet the defined criteria.
