SQL is a language that operates the database. This includes database creation, delete, database to retrieve specific data.

SQL is an ANSI (American National Standards Institute) standard language, but there are many different versions of the SQL language. In today’s post (SQL Full Form: ) know about SQL.

What is SQL?

SQL is a standardized programming language used to manage relational databases and perform various operations on their data.

SQL is Structured Query Language, which is a computer language to store, manipulate and retrieve data stored in relational databases.

SQL is a standard language for relational database systems. All Relational Database Management Systems (RDMS) like MySQL, MS Access, Oracle, Sybase, Informix, Postgres and SQL Server use SQL as their standard database language.

SQL to data share Found – The data is organized into tables and multiple files, each containing tables of data, they can be related together by a common field.

Using SQL, you can query (request information from a database), update and re-organize data, as well as create and modify the schema (struct) of a database system, and Can control access.

What is the meaning of SQL – Meaning of SQL

Meaning of SQL:

SQL stands for Structured Query Language.

What can SQL do?

  • SQL can execute queries in a database.
  • SQL can retrieve data from database.
  • SQL can insert records into a database.
  • SQL can update records in the database.
  • SQL can delete records in the database.
  • SQL can create a new database.
  • SQL can create new tables in a database.

What is the history of SQL?

The origins of SQL go back to the 1970s, when new database software was created at IBM Laboratories – named System R and the SQL language was created to manage the stored data in System

It was first called SEQUEL, a name that is still used as an alternative pronunciation for SQL, but has since changed to just SQL.

In 1979, a company called relational software, which later became Oracle, saw the commercial potential of SQL and released its own modified version called Oracle V2.

Now in its third decade of existence, SQL offers great flexibility to the users by supporting distributed database, i.e. which can be run on multiple computer networks at a time. Certified by ANSI and ISO, SQL has become a database query language standard.

It serves both industry-level and education needs and is used on both personal computers and corporate servers. With the advancement of database technology, SQL-Base applications have become increasingly affordable for regular users. This is due to the introduction of various open source SQL database solutions such as MySQL, PostgreSQL, SQLite, Firebird, and many more.

What are the advantages of SQL?

  • SQL allows users to access data in relational database management systems.
  • Users can describe the data.
  • Users can define the data in the database and can also manipulate that data.
  • SQL can be embedded in other languages ​​using modules, libraries, and pre-compilers.
  • Users can create and drop databases and tables.
  • Users can create views, store procedures and create functions in the database.
  • Users can set permissions in tables, procedures and views.

Is it difficult to learn SQL?

Learning SQL is really not that hard.

SQL is not a programming language, it is a query language. It is also an English-like language, so anyone who can use English at a basic level can easily write SQL queries. The good news is that most DB engines are compatible with all SQL code.

Can I learn SQL myself?

The best way to learn SQL is to practice it. Install a free open source database so you can start writing and running simple queries using your own data. Once you learn the fundamentals of SQL and feel comfortable running queries, it’s time to take the certificate.

Where can I practice SQL?

If you’re new to the world of SQL, however, it can be hard to figure out where and how to get that all-important practical experience.

Great resources for practicing SQL online are given below.

1) Introduction to SQL: Queries and Management of Data via Khan Academy

This course starts with SQL Basics (perfect for beginners looking to learn SQL for the first time), then expands to:

  • More Advanced SQL Query
  • Querying Relational Query in SQL
  • Modifying Databases with SQL
  • Further Learning in SQL

2) Codecademy’s Free SQL Class

Codecademy promises that if beginners take this SQL course, they will “learn to communicate with databases using SQL, the standard data management language.” This means four text sections on the following SQL-related topics:

  1. Manipulation
  2. Queries
  3. Aggregate Function
  4. Multiple Tables

3) Developing sql databases via EdX

I always mention EdX in my roundup of free coding resources because the quality is superb. Courses are sourced from universities including MIT and Harvard, and its free SQL classes are no different.

4) SQLcourse.com

If you can handle the awful old website, this resource is full of really great (and yes, free) interactive SQL lessons and tutorials. Great for teaching yourself at your own pace.

5) W3Schools SQL Class

There’s a reason W3Schools seems to be everywhere – they consistently make great online coding and technical classes for beginners. The same is true of their SQL tutorial, which has a highly UX-friendly sidebar table of contents and straightforward examples.

How many elements are there in SQL language?

SQL Language Elements

Elements of SQL in English – SQL language is based on many elements. For the convenience of SQL developers, all required language commands in the respective database management systems are usually executed through a specific SQL command line interface (CLI).


Clauses are components of statements and queries.


Expressions can produce scalar values ​​or tables, consisting of columns and rows of data.


They specify conditions, which are used to limit the effect of statements and queries, or to change the flow of the program.


A Queries retrieves the data based on the given criteria.


Statements allow anyone to control transactions, program flows, connections, sessions, or diagnostics. In database systems, SQL statements are used to send queries from the client program to the server, where the database is stored.


Statements allow anyone to control transactions, program flows, connections, sessions, or diagnostics. In database systems, SQL statements are used to send queries from the client program to the server, where the database is stored.

In response, the server processes the SQL statement and replies to the client program. This allows users to execute a wide range of surprisingly fast data manipulation operations, from simple data input to complex queries.

What are SQL Queries? Explain with example

SQL queries are the most common and essential SQL operations. Through a SQL query, one can search the database for the required information.

SQL queries are executed with a “SELECT” statement. A SQL query can be more specific with the help of multiple clauses:

FROM- This indicates the table where the search will be done.

WHERE – It is used to define the rows in which the search will be done. All rows for which the WHERE clause is not true will be excluded.

ORDER BY – This is the only way to sort results in SQL, otherwise, they will be returned in a random order.

A SQL query example-


WHERE active

ORDER BY LastName, FirstName

some of the most important SQL commands 

SELECT – Extracts data from the database.

UPDATE – Updates the data in the database.

DELETE – Deletes data from the database.

INSERT INTO – Inserts new data into the database.

CREATE DATABASE – Creates a new database.

ALTER DATABASE – Modifies the database.

CREATE TABLE – Creates a new table.

ALTER TABLE – modifies the table.

DROP TABLE – Deletes the table.

CREATE INDEX – Creates an index

DROP INDEX – Deletes the index.

SQL SELECT Statement:

SELECT statement is used to select data from database.

The return data is stored in the result table, which is called result-set.


SELECT column1, column2, …

FROM table_name;

Here, column1, column2, … are the field names of the table from which you want to select the data. If you want to select all the fields available in the table, use the following syntax:

SELECT * FROM table_name;
