SQL QUERY Meaning and
Definition
-
An SQL query, also known as Structured Query Language query, refers to a set of instructions or commands used for retrieving data or performing operations on a relational database. SQL is a programming language designed for managing and manipulating data stored in a database system.
A SQL query is a statement written in SQL syntax that specifies what data needs to be retrieved from the database or what operation needs to be performed on the data. It allows users to communicate with and interact with the database by querying, updating, and deleting records.
A typical SQL query consists of various components, including the SELECT statement that specifies the columns to be retrieved, the FROM clause that identifies the table(s) to query, and optional clauses like WHERE, GROUP BY, HAVING, and ORDER BY that help filter, group, and sort the data. The SELECT statement defines the output of the query, while the clauses refine the result set based on user-specified conditions.
SQL queries provide a powerful and flexible way to extract information from databases. They are widely used in applications that involve data retrieval, data analysis, and generating reports. SQL queries enable users to access and manipulate data efficiently, making them an essential tool for working with relational databases.

Etymology of SQL QUERY
The term "SQL query" is derived from the combination of two separate elements: "SQL" and "query".
1. SQL: SQL stands for Structured Query Language, a programming language developed in the 1970s by IBM. It was initially called "SEQUEL" (Structured English Query Language), but due to copyright issues, its name was later changed to "SQL". SQL is widely used for managing and manipulating relational databases.
2. Query: A query in general refers to a request for information from a database or any other data repository. In the context of SQL, a query is a specific instruction or statement written in SQL syntax to retrieve or manipulate data in a relational database. It allows users to ask questions, perform searches, and extract relevant data.
So, when combined, "SQL query" becomes a term used to describe the action of using the SQL language to retrieve or manipulate data from a relational database.
