Do you mean why do you need a query in a database? But what ever it is I have absolutely no beeping clue but I should as we are studying this at school (yr 11)
You are searching the database or extracting data from the query.
yeah, database is a query language,, abd it is stored datas
Query Language is way for communicating from the database. It work as a interface between user and the Database. its not possible to generate a result from database without query language. Query language helps us to communicate with database.
SQL stands for Structured Query Language as it refers to the type of database query or database server which accepts the query.
In databases, a query is a request for information from a database. It is usually written in a special query language, such as SQL, and is used to retrieve, update, or manipulate data stored in the database. Queries allow users to interact with the database to extract the specific information they need.

A database record is a single row in a database. A recordset (or cursor) represents a query, and looks like (part of) a record or row. It is actually a row of the query, or virtual table representing the query. When you submit a query that returns data, you create a recordset and the database fills it in with the first record that matches the predicate clause. You do what you need to do with that data. When you need the next record, you fetch the next row, and so on and so forth. Some recordsets represent more than one row at a time. That is up to the database and your program design, but the concept is the same - the recordset is all or part of the resultset from the query.
a query allows you to select certain data
A query can be used to do things with the data. Mostly it is to extract information from the database, but they can also be used to delete, edit and update a database. Queries are very important and powerful aspect of a database.
When you request specific data from a database, it is called a query. A query is a request for information from a database that matches certain criteria. This is commonly done using Structured Query Language (SQL) commands to retrieve the desired data.
The database we use is based on structured query language . To add or retrieve data from the database we use SQL . SQL is the structured query language that provides the syntax to add, modify, update or retrieve data from the database.
A database "query" is basically a "question" that you ask the database. The results of the query is the information that is returned by the database management system. Queries are usually constructed using SQL (structured query language) which resembles a high-level programming language.
