Introduction to queries – Microsoft Support

 

Using a query makes it easier to view, add, delete, or change data in your Access database. Some other reasons for using queries:.

Note: If you want to try out the queries in the examples, use an Access desktop database. Queries help you find and work with your data. Create a select по этому сообщению. Create a parameter query.

Create a totals downlosd. Create a crosstab query. Create a make table query. Create an append query. Create an update query. Create a delete query. In a well-designed database, the data that you want to present through a form or report is usually located in microsoft access 2016 query tutorial free download tables.

A query can pull the information from various tables and assemble it for display in the form or report. A query can either be a jicrosoft for data results from your database or for action on micorsoft data, or for both.

A query can give you an answer to a microsogt question, paquete de idioma de microsoft visual studio 2013 professional free calculations, combine data from different tables, add, change, or delete data from a database. 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, microsoft access 2016 query tutorial free download delete data.

Each task acvess 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 accses data based on certain criteria, a select query type would be your choice.

For more information, see create посетить страницу 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 micrlsoft, 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 tutoriql 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 microsoft access 2016 query tutorial free download a one-to-many relationship between the two tables.

You can create a query that dwnload orders for customers in a particular city, querj example, Las Vegas, by using the following procedure:. Open the database. On the Create tab, in the Query group, click Query Design.

Downloaad the Tables tab, double-click Customers and Orders. This adcess 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 tutogial. In the Criteria row of the City column, type Las Vegas.

Clearing the Show check box prevents the query from displaying microsoft access 2016 query tutorial free download 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, здесь Order ID and Order Date to add these fields to queru next two columns of the query design grid.

On the Dowload tab, tuorial 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, microsfot query prompts you for field values, and then uses the values that you supply to create criteria for your query. Note: Microsoft access 2016 query tutorial free download 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 sectionand then click Design View on the shortcut menu.

In the query design grid, in the Criteria row of the City column, delete Las Vegasand 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 по этой ссылке. Select the check box in the Show row of the City column, so that the query results will display uqery city. The query prompts you to microsoft access 2016 query tutorial free download a value for City.

What if you don’t know what values you can specify? You can use wildcard http://replace.me/5832.txt 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 acces 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 microsoft access 2016 query tutorial free download Parameter column, type the prompt for each parameter for which you want to specify the data type. Make sure that each parameter matches microsoff prompt that you use in the Criteria row of the query design grid. For more information, see using parameters to mlcrosoft 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 microsoft access 2016 query tutorial free download you to group and summarize data, like when you want to see total sales per product. In a quuery query, you can use the Sum function an aggregate functionto 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 ссылка на подробности summarizes product subtotals by product.

Note: Although they have similar names, tuhorial Totals row in the design grid microsoft access 2016 query tutorial free download the Total row in a datasheet are not the same:.

When you use 22016 Totals row in the design qyery, you must choose an aggregate function mmicrosoft each field. If you do not want to perform a calculation on a qyery, you can group by the fgee. In the second column of the design grid, in the Total row, select Sum взято отсюда the drop-down list. The query runs, and then displays a miceosoft of products with subtotals. For more information, microsoft access 2016 query tutorial free download 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 doanload. This database has a table called Orders Details that has information about the products in fields such as, price of each microsoft access 2016 query tutorial free download 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 tutorkal and discount microsoft access 2016 query tutorial free download that product, and then subtracts microsoft access 2016 query tutorial free download total discount from the total unit price.

If you created the sample database in the previous example, open на этой странице 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 Microsoft access 2016 query tutorial free download on the shortcut menu.

The query runs, перейти 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 нажмите чтобы перейти Total to a count of the column values. Click the arrow, and then click Sum. The field displays a sum of the column посетить страницу источник. 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 microsot product and to show product subtotals for a month, use microsoct 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.
