Microsoft Access Queries tutorials
Creating a query that uses multiple criteria for a field is like running a filter on your query results. For example, if you have a table that contains complete addresses of all your friends, you can run a query that will display brief information for those who live in New York, or for those who live in New York and whose surname starts with the letter "B".

Create a Query That Uses Multiple Criteria in One Field
When you create a query that uses multiple criteria in one field for Access 2003, you restrict the number of search results that you will receive from that query. The multiple criteria can be either inclusive or exclusive depending on how the criteria are joined.
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.

Create a Query in Microsoft Access Using Simple Equal To Criteria
This quick and easy tutorial will explain how to create a query using criteria. There are MANY types of criteria that can be used in a query, but for now we'll focus on a basic query to get started. We will first see how to retrieve customer data for customers that live in a particular state. Then, we will see how to expand this criteria to search for customers across multiple states at one time.
Using multivalued fields in queries
In Microsoft Office Access 2007, you can create a field that holds multiple values, such as a list of people to whom you have assigned an issue. Multivalued fields are appropriate for certain situations, such as when you use Office Access 2007 to work with information stored in a Microsoft Windows SharePoint Services 3.0 list, and that list contains a field that uses one of the multivalued field types available in Windows SharePoint Services 3.0. This article discusses multivalued fields and how to use them in queries. In this article * What is a multivalued field? * Introducing queries * Displaying a multivalued field in a query * Displaying the individual values in a multivalued field * Understanding the bound value and the display value in a lookup field * How to display the bound value in a query * Entering simple query criteria for a multivalued field * Searching for more than one value in a multivalued field * Understanding the impact of including a .Value field in the field list. * Counting, grouping and using other aggregate functions * Using an Append query with a multivalued field * Using an Update query with a multivalued field * Using a Delete query with a multivalued field
Filter Query Results from a Combo Box
You should be aware that you can limit the results of a database select query by using particular criteria. The article relating to Microsoft Access Database Query Basics gives a breakdown on applying simple query criteria. What if you are not too sure about what criteria applies to the particular field - wouldn't it be better to be able to choose this from a list rather than having the standard Microsoft Access input box appear...
Examples of query criteria
If you are interested in including only those records that match your criteria in a query, then specify one or more criteria at the time of designing the query.

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!
How to create a Microsoft Access Append query with criteria
A Microsoft Access append query can be used to add records to an existing database table. Prior to creating an append query, decide upon the two Microsoft Access tables that you would like to use. One table will contain the records you would like to add and the other table will be the table to which the records will be added. At the completion of this "how-to" will be a database table that has additional records added to it based upon specified criteria. Select the two database tables that will be included in the query. Ensure that the data types for the information in the corresponding tables are the same. For example, if the information in the date field is being added to a table, ensure that the field in the corresponding table is formatted for dates.

There is also information on query optimization and using calculations within the query. Hopefully you will find something of interest, whether you need to limit results of the query by applying simple criteria to designing expressions to calculate data on the fly.
Specify criteria for a text field
Want to limit the results of your query based on the value of a text field? You can specify exact values that you want a query field to match, partial values to match, or a set of values, any one of which to match. You can also exclude results based on specified values. Watch this demo to see how to do it.
Delete a field
You can delete a field from a query or from a table. When you delete a field from a query, the field remains in the database, but is no longer used in the query. When you delete a field from a table, the field is deleted from the entire database. This topic provides an overview of the considerations and process of deleting fields, and gives steps for deleting a field from a query or a table.
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.
Numeric Criteria Expressions
To specify numeric criteria for an operation, you supply a numeric value as part of the string expression that forms the criteria argument. Suppose that you are performing the DLookup function on an Employees table to find the last name of a particular employee, and you want to use a value from the EmployeeID field in the function's criteria argument.

Extended DAvg()
The DAvg() function built into Access lets you get the average of a field in a table, and optionally specify criteria. This EAvg() function extends that functionality, so you can get the average of just the TOP values (or percentage) from the field. You can even specify a different field for sorting, e.g. to get the average of the 4 most recent values. Code to average a field in a table/query in Microsoft Access, with the option to count the TOP values. A replacement for DAvg().
Multiple Table Queries
Most of the queries you create in Microsoft Access will more that likely need to include the data from more than one table and you will have to join the tables in the query. The capability to join tables is the power of the relational database. As you know, in order to join database tables, they must have a field in common. The fields on which you join tables must be the same or compatible data types and they must contain the same kind of data, however they do not have to have the same field name (although they probably will). Occasionally, the two database tables that you want to bring the data from may not have a field in common and you will have to add another table to the query with the sole purpose of joining the tables.
Percentage Calculation-Forms
I have a field in query "Car_Value" then I want create a field (not in table/query) "Percent_15%" formatted 'number', and another field (not in table/query), "15%_OF_Car_Value". I want to calculate Percent_15% with Car_value, and show this value in "15%_OF_Car_Value". For some reason If I put in any number in percent_15% field it is disappering...
Calculated fields
A calculated field is a "virtual field" in a query. The field is virtual in the sense that it is not stored anywhere in the database. Instead, it is calculated dynamically when the query is used. Learning objectives: create a calculated field; understand why ACCESS add square; brackets around field names; understand the use of the ampersand operator (&). (pdf file, install Acrobat Reader to read this tutorial)
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.
Add a subdatasheet
When two tables have one or more fields in common, you can embed the datasheet from one table in another. An embedded datasheet, which is called a subdatasheet, is useful when you want to view and edit related or joined (join: An association between a field in one table or query and a field of the same data type in another table or query. Joins tell the program how data is related. Records that don't match may be included or excluded, depending on the type of join.) data in a table or query (query: A question about the data stored in your tables, or a request to perform an action on the data. A query can bring together data from multiple tables to serve as the source of data for a form, report, or data access page.). In this article * Introduction to subdatasheets * Open and close a subdatasheet * Add a subdatasheet
Create a Query Using More Than One Field
A single-field query in Microsoft Access 2003 extracts specific information from a database, such as “everybody with a birthday in November.” You can add other fields to this--say, making the query “everybody with a birthday on an even day in November who is under 60.” Here’s how to use more than one field in Access 2003 queries.
Build a search criteria form
A flexible search form provides several boxes where a user can enter criteria. An efficient search form creates the criteria from only those boxes where the user enters a value. This tutorial illustrates how to use: * Exact matches, * Partial matches (wildcards), * A range of values, * Delimiters for each field type, * Any combination of criteria, * A design that is easy to extend.
Parameter Query Criteria
I successfully created two tables. Products table and supplier table. I created a list box in the supplier table for products listed in the product table. I created a parameter query from the supplier table. My problem is the criteria. I would like to create a report from the parameter query. I would like this report to have a list box to select a product from the product table which would go into the criteria of the parameter query to form the report. I have been all over the help in access and cannot figure out how to do this. Your help would really be appreciated.
