In Access to build a query to the database using the method QBE (query-by-example - query by example) - a method of querying invented by IBM back in the 1970s. Queries provide easy access to a specific subset of fields and records one or more tables.
Request-sample. Straight query that simply selects the required data and the results of the sample plays in the form of dynamic typing. Last superficially similar to the table, but is dynamic (or virtual) set of records, built on the structure of the query. Records in dynamic typing does not actually exist, so when this set is not active, burn disappear (but the data on which was built the set, remain in the original table). The request nota fiscal can be saved, but the data are reproduced during nota fiscal its execution, it is not stored. When you save a query in a SQL statement is stored only Structure request.
Perekrestnыe zaprosы. Allow to submit data from Access database tables in a format that resembles a spreadsheet. With these queries, you can group a wealth of information and present nota fiscal it in an easy to understand format.
In Access, you can create queries manually or using the Master zaprosov. Master zaprosov Access nota fiscal contains a special tools that are used to solve complex problems (for example, search results, repetitive, or view the data request for a cross).
In the dialog box, the Create request for (New Query) click Design (Design View) and click the OK button. This will open a window nota fiscal with a request for Konstuktor dialog Dobavlenye tablytsы (Show Table) (Figure 3.10).
In the constructor creates a new request for the request. The attached tables involved in the query, the tables are chosen nota fiscal fields, the conditions that must be satisfied nota fiscal by the selected records, and sort order. By creating nota fiscal a query, you can save or print the results of its implementation.
After opening the box Zaprosы (Queries) first action in the process of developing nota fiscal a new request is to add tables from which selected data. In the dialog box Dobavlenye tablytsы (Show Table) (see Fig. 3.10) mark the table (or tables) that is used in the query. nota fiscal
In the query, you can use one or more tables. Creating nota fiscal queries with multiple tables, you must define a common field that links the tables nota fiscal by dragging it from the window of one table in a second window. Queries that use multiple nota fiscal tables are called relational.
Creating a relational query for each table (or query used in a query that creates IS) neohidno select the table (or query) in the dialog box Dobavlenye tablytsы (Show Table), and click the mouse on the Add button (Add). nota fiscal After adding nota fiscal the necessary nota fiscal tables and queries, click on the button Close (Close), shob close the dialog box Dobavlenye Table Y (Show Table).
If the user closed the dialog Dobavlenye tablytsы (Show Table), and then decided that you need to add another table or query, click on the button Dobavlenye Table Y (Show Table) on the toolbar or run the command and its option Request Add table (Query Þ Show Table). Add Table Dialog (Show Table) opens.
After closing the dialog box, the Add Table (Show Table) on the screen is a window designer invited, that will put windows tables and queries that were added in the query is created. In Fig. 3.11 recreated a window (in this case, the request has been added to The developed one table - Sklad).
Request for Window Design nota fiscal is divided into two parts. At the top of the window placed tables and queries used in the created query, and at the bottom - the request form QBE. In blanc ku query defined fields
