To accommodate all possible dates, set the Field Size property of your Number field to Long Integer or greater. Values must not exceed or fall below the size limit set for the field. For example, you can convert a Currency field to an Integer field only when those values are greater than and do not exceed 32, The value -1 Yes converts to December 29, The value 0 No converts to midnight AM. If the original text contains a valid Web address, such as adatum.
Access tries to convert other values, meaning that you see underlined text, and the cursor changes when you point at the link, but the links don't work.
Not allowed when a Number field is part of a relationship. If the original value is in the form of a valid Internet Protocol IP address four number triplets separated by a period: nnn. Not allowed when the AutoNumber field is part of a relationship.
The resulting links do not work. If you try to run an action query and it seems like nothing occurs, check the Access status bar for the following message:. By default, Access disables all action queries update, append, delete, or make table queries unless your database is in a trusted location or the database is signed and trusted.
If you have not taken either of these actions, you can still enable the query for the current database session by clicking Enable Content on the Message Bar. An expression that determines the value to be inserted into a particular field in the updated records.
An expression that determines which records will be updated. Only records that satisfy the expression are updated.
You can change several fields at the same time. The following example increases the Order Amount values by 10 percent and the Freight values by 3 percent for shippers in the United Kingdom:.

Since queries are so versatile, there are many types of queries and you would create a type of query based on the task. Add, change, or delete data. Each task has a specific type of action query.
Action queries are not available in Access web apps. If you want to review data from only certain fields in a table, or review data from multiple tables simultaneously or maybe just see the data based on certain criteria, a select query type would be your choice. For more information, see create a simple select query. Open the database and on the Create tab, click Query Design.
Double-click the Product Name and List Price to add these fields to the query design grid. On the Design tab, click Run. The query runs, and displays a list of products and their prices. For example, if you have a database for a store that sells food items and you want to review orders for customers who live in a particular city. Say that the data about orders and data about customers are stored in two tables named Customers and Orders respectively.
If each table has a Customer ID field, which forms the basis of a one-to-many relationship between the two tables. You can create a query that returns orders for customers in a particular city, for example, Las Vegas, by using the following procedure:.
Open the database. On the Create tab, in the Query group, click Query Design. On the Tables tab, double-click Customers and Orders. This line shows the relationship between the two tables. In the Customers table, double-click Company and City to add these fields to the query design grid. In the query design grid, in the City column, clear the check box in the Show row. In the Criteria row of the City column, type Las Vegas. Clearing the Show check box prevents the query from displaying the city in its results, and typing Las Vegas in the Criteria row specifies that you want to see only records where the value of the City field is Las Vegas.
In this case, the query returns only the customers that are located in Las Vegas. In the Orders table, double-click Order ID and Order Date to add these fields to the next two columns of the query design grid. On the Design tab, in the Results group, click Run. The query runs, and then displays a list of orders for customers in Las Vegas. If you frequently want to run variations of a particular query, consider using a parameter query. When you run a parameter query, the query prompts you for field values, and then uses the values that you supply to create criteria for your query.
Note: You cannot create a parameter query in an Access web app. Continuing from the previous example where you learnt to create a select query that returns orders for customers located in Las Vegas, you can modify the select query to prompt you to specify the city each time that you run the query. To follow along, open the database that you created in the previous example:. In the Navigation Pane, right-click the query named Orders by City that you created in the previous section , and then click Design View on the shortcut menu.
In the query design grid, in the Criteria row of the City column, delete Las Vegas , and then type [For what city? The string [For what city? The square brackets indicate that you want the query to ask for input, and the text in this case, For what city?
Note: Neither a period. Select the check box in the Show row of the City column, so that the query results will display the city. The query prompts you to enter a value for City. What if you don't know what values you can specify? You can use wildcard characters as part of the prompt:.
In the query design grid, in the Criteria row of the City column, type Like [For what city? You can also specify what type of data a parameter should accept. When you specify the data type that a parameter should accept, users see a more helpful error message if they enter the wrong type of data, such as entering text when currency is expected.
If a parameter is set to accept text data, any input is interpreted as text, and no error message is displayed. When the records in your tables match your criteria, the action specified in your query is run.
There are multiple query types that you can use in Microsoft Access. Here we show how you can create those queries in Access.
As the name suggests, a Select query in Access lets you select and retrieve certain records from your tables. You can specify a custom condition and Access will retrieve only the records matching this condition.
Before you create a query, you must have a table in your database. An Update query looks much like a Select query but this one edits your table records. This query modifies and updates the records in your tables using your custom criteria. Get the Latest Bytes Updates. By using this site, you agree to our Privacy Policy and Terms of Use.
