Introduction to queries
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. In the Query Parameters dialog box, in the Parameter column, type the prompt for each parameter for which you want to specify the data type. Make sure that each parameter matches the prompt that you use in the Criteria row of the query design grid.
For more information, see using parameters to ask for input when running a query. The Total row in a datasheet is very useful, but for more complex questions, you use a totals query. A totals query is a select query that allows you to group and summarize data, like when you want to see total sales per product.
In a totals query, you can use the Sum function an aggregate function , to see total sales per product. Note: You cannot use aggregate functions in an Access web app. Use the following procedure to modify the Product Subtotals query that you created in the previous example so that it summarizes product subtotals by product. Note: Although they have similar names, the Totals row in the design grid and the Total row in a datasheet are not the same:.
When you use the Totals row in the design grid, you must choose an aggregate function for each field. If you do not want to perform a calculation on a field, you can group by the field.
In the second column of the design grid, in the Total row, select Sum from the drop-down list. The query runs, and then displays a list of products with subtotals. For more information, see Display column totals in a datasheet using a Totals row. You usually would not use tables to store calculated values, like subtotals, even if they are based on data in the same database, because calculated values can become outdated if the values that they are based on changes. For example, you would not store someone's age in a table, because every year you would have to update the value; instead, you store the person's date of birth, and then use a query to calculate the person's age.
This database has a table called Orders Details that has information about the products in fields such as, price of each product and the quantities. You can calculate the subtotal by using a query that multiplies the quantity of each product by the unit price for that product, multiplies the quantity of each product by the unit price and discount for that product, and then subtracts the total discount from the total unit price. If you created the sample database in the previous example, open it and follow along:.
In the Order Details table, double-click Product ID to add this field to the first column of the query design grid. In the second column of the grid, right-click the Field row, and then click Zoom on the shortcut menu. The query runs, and then displays a list of products and subtotals, per order. When you use tables to record transactions or store regularly occurring numeric data, it is useful to be able to review that data in aggregate, such as sums or averages.
In Access, you can add a Totals row to a datasheet. Total row is a row at the bottom of the datasheet that can display a running total or other aggregate value.
Run the Product Subtotals query you created earlier, and leave the results open in Datasheet view. On the Home tab, click Totals. A new row appears at the bottom of the datasheet, with the word Total in the first column. Click the arrow to view the available aggregate functions. Because the column contains text data, there are only two choices: None and Count. Select Count. The content of the cell changes from Total to a count of the column values.
Click the arrow, and then click Sum. The field displays a sum of the column values. Now suppose that you want to review product subtotals, but you also want to aggregate by month, so that each row shows subtotals for a product, and each column shows product subtotals for a month. To show subtotals for a product and to show product subtotals for a month, use a crosstab query. Note: A crosstab query cannot be displayed in an Access web app.
You can modify the Product Subtotals query again so that the query returns rows of product subtotals and columns of monthly subtotals. On the Design tab, in the Query Type group, click Crosstab.
In the design grid, the Show row is hidden, and the Crosstab row is displayed. In the third column of the design grid, right-click the Field row, and then click Zoom on the shortcut menu. The Zoom box opens. In the Crosstab row, select the following values from the drop-down list: Row Heading for the first column, Value for the second column, and Column Heading for the third column.
The query runs, and then displays product subtotals, aggregated by month. For more information about crosstab queries, see Make summary data easier to read by using a crosstab query. Note: A make-table query is not available in Access web apps. For example, suppose that you want to send data for Chicago orders to a Chicago business partner who uses Access to prepare reports.
Instead of sending all your order data, you want to restrict the data that you send to data specific to Chicago orders. You can build a select query that contains Chicago order data, and then use the select query to create the new table by using the following procedure:.
Note: If you see a message beneath the Ribbon about enabling the database, click Enable content. If your database is already in a trusted location, you will not see the Message Bar. In the Ship City column of the design grid, clear the box in the Show row. For more information about queries, see the article Introduction to queries. Macros in Access can be thought of as a simplified programming language which you can use to add functionality to your database.
For example, you can attach a macro to a command button on a form so that the macro runs whenever the button is clicked. Macros contain actions that perform tasks, such as opening a report, running a query, or closing the database. Most database operations that you do manually can be automated by using macros, so they can be great time-saving devices.
For more information about macros, see the article Introduction to Access programming. Modules, like macros, are objects you can use to add functionality to your database.
Whereas you create macros in Access by choosing from a list of macro actions, you write modules in the Visual Basic for Applications VBA programming language. A module is a collection of declarations, statements, and procedures that are stored together as a unit. A module can be either a class module or a standard module. Class modules are attached to forms or reports, and usually contain procedures that are specific to the form or report they're attached to.
Standard modules contain general procedures that aren't associated with any other object. Standard modules are listed under Modules in the Navigation Pane, whereas class modules are not.
For more information about modules, see the article Introduction to Access programming. Need more help? Expand your skills. Get new features first. Was this information helpful? Yes No. Thank you!

Steps 2 Select the Datasheet view option in the ribbon and add some data by entering the values in It. Updated Data will be Autosaved. Step 3 Select the row by clicking on the leftmost column and Right Click on the row. Step 4 Popup Window will appear to confirm the deletion of the record. Displays the view, which allows you to enter fields, data types, and descriptions into your database table.
To understand form lets first create two new Record in Contact Table from the prebuilt Contact Database discussed here. This option allows the user to create the form with the wizard and select the column from the available list of column form in legacy Select window format.
Step 5 Layout selection box will appear which allows the user to select the different type of form layout. It is another type wherein All the records already created will be displayed in Form with an option to Add new record.
It is a mix of simple form and split form in a way that this form provides the view of Form and datasheet in a split window. Whatever the user enters in Form is visible directly in Datasheet view immediately and vice versa.
Step 3 Manually fill the data from Form. Note that in split form all data will be automatically reflected in below data sheet as well. Skip to content. What is Microsoft Access?
