Online SQL formatter

SQL meaning

SQL stands for Structured Query Language. It is a programming language to perform various operations on data and manage relational databases. It is also known as database language because it deals with and communicates with the database, i.e. data extraction, organization, management or manipulation, etc. Web developers use SQL servers on a daily basis in their careers.

Uses of SQL

SQL is used to create, edit, retrieve or delete tables in a database. It is also used for changing data structure, defining database schema, combining datasets with the help of "JOIN" query and data manipulation. Besides all this, developers also use this database language to grant or restrict access to users. You can also use SQL to analyze data manually.

Who invented SQL and when

IBM researchers Raymond Boyce and Donald Chamberlin introduced SQL programming language in the 1970s under the name "SEQUEL". They took the idea of developing database language from Frank Codd's research paper, “A Relational Model of Data for Large Shared Data Banks”, in which he shared his thought that all data in a database must present in the form of relations.

What is the online SQL formatter tool

SQL formatter is a free online tool to convert complex SQL code into a human-readable form. Code that is easy to read is easier to understand. Moreover, a particular and standard coding style reduces the risk of mistakes and enhances code quality.

Free online SQL formatter uses SQL conventions to format a code, i.e. introducing consistent white space, indentation level, grouping lines, add patterns, naming and comments. Freenerdtools' free SQL formatter is a widely used beautifier to format SQL code easily and automatically. It analyses code and makes the quality of the code visible instantly.

How to beautify SQL queries using Freenerdtools

The quality of SQL code is not just in its execution but also in its appearance. So, go to Freenerdtools and select SQL formatter/beautifier from the tools list to get well-formatted SQL statements instantly. The online SQL query formatter interface is simple and free from any kind of technical complexities.

You don't have to download this SQL beautifier in your system for using it. Start by just copying and pasting your SQL query syntax in the text box and press the submit button at the end to command SQL formatter online to beautify SQL statements. You can also write an instant MySQL script directly in the textbox. You don't have to choose any formatting options from the settings to get comprehensive select statements.

Let's check the power of a free online SQL formatter by running a common Oracle query task: 

 SELECT column1, column2 FROM table1, table2 WHERE column2='value'; 

On pressing the submit button, it generates the following easy to read code:

  column2 = 'value';

Look at the output. It seems pretty and makes the code comprehensive and easy to analyze.

Importance of formatting your SQL code

Every programming language has its own style. It also depends on the editor you are using, i.e. Visual Studio or notepad. Besides having a personal code style, it's convenient to follow the industry style standards. In this way, not only you but other developers can also comprehend and handle your code.

In other words, following SQL code formatting options makes errors obvious and enhance your code communication across the developers' network. Code style doesn’t really matter to the machine that is running it, but it helps developers a lot who have to maintain the code.

What makes structured query language so popular?

The immense popularity of SQL lies in its simplicity and ease of use. Moreover, it effectively manipulates and performs a variety of database operations to transform huge collections of structured data into usable information.

Are there SQL alternatives?

  • PL/SQL: It is a combination of SQL and procedural features of programming languages. Besides telling "what to do?", it also explains "how to do?".
  • IBM Db2: It is software used to manage relational databases. It comprises AI-powered capabilities to manage both structured and unstructured data across on-premises and multi-cloud environments.
  • Teradata Vantage: It is a data analytics platform to solve complex descriptive, predictive and prescriptive business analytics to make the decision-making process faster.

What is NoSQL

NoSQL means not only SQL, i.e. non-relational database. It is a class of non-relational DBMS that do not allow SQL use and store data in a format other than relational tables.

NoSQL databases are schema-less, making them more flexible and scalable than traditional relational databases. They can be used to store large volumes of unstructured data such as documents, images, audio files, videos, and other multimedia content. NoSQL databases also provide high availability and scalability for mission-critical applications. Examples of NoSQL databases include MongoDB, Cassandra, Redis, Neo4j, and Couchbase.
