The results are not saved, but the query can be. If the query has been saved, then it can be run at any time to retrieve the data. So it is not necessary to save the data itself. You can write queries that will select data and write it to a new table, in which case the results are being saved.
Each time you open a saved query, the system retrieves the stored parameters and settings associated with that query. It executes the query against the relevant database or dataset, generating the latest results based on the current data. Additionally, any filters or conditions previously applied are reinstated, allowing you to view the data as intended. This ensures that you are working with the most up-to-date information while maintaining the context of your original query.
You can export your query results in various formats, including CSV, JSON, Excel, and XML. The specific options available may depend on the database or software you are using. Typically, these formats allow for easy data manipulation and integration with other tools. Always check the export options in the application you are using to verify available formats.
It is a types of testing in which one will perform write query using sql statement whatever data you fill that data should be saved in back end . for eaxmple my sql,sqlserver, oracle like that so on.

The * symbol is a universal wildcard symbol. In the Access Query By Example Design Pane, the * represents all fields in the table or query.
open on the shorcut menu,
Run the query. If in Design view you can do that by clicking on the red exclamation mark. If you go to the window and open the query directly, it will run.
To run a saved query in design view, first, open the database application and locate the saved query in the navigation pane. Right-click on the query and select "Design View" to open it in the design interface. Review or modify the query as needed, then click on the "Run" button (often represented by a red exclamation mark) in the toolbar to execute the query and view the results. If changes were made, ensure to save the query before running it to retain any modifications.
Query is an instruction given to Database engine to retrieve the results. Example: Select EmployeeName From tblEmployees Where EmployeeID = 123; This is a sample query to retrieve the Name of a particular employee from the set of records saved already.
In MS Access, a Query is a saved search, which can be used in reports, etc.

Query by Example (QBE) is a database query language for relational databases. A QBE parser parses the search query and looks for the keywords. A more formal query string, in languages such as SQL, is then generated, which is finally executed. However, when compared with a formal query, the results in the QBE system will be more variable.SQL (Structured Query Language) SQL is a set-based, declarative query language, not an imperative language such as C or BASIC. However, there are extensions to Standard SQL which add procedural programming language functionality, such as control-of-flow constructs
