Developers and database administrators should format SQL correctly. Formatting makes code easier to read and prevents syntactic errors. But hand-coding is laborious. This blog post will review the best SQL formatters, including PostgreSQL, Oracle SQL formatters, and free online resources. We’ll also discuss SQL formatting best practices and how to choose a SQL formatter.

SQL is prevalent in IT for database administration. Programmers and DBAs can use it to manipulate databases and retrieve data. Yet, writing long or intricate SQL code can take time and effort.

This blog post will discuss the best online SQL formatter tools, SQL formatting best practices, and writing clean, readable SQL statements.

SQL Formatters

SQL Formatter

A program known as a SQL formatter automatically formats your SQL code to make it more understandable and logical. Indentation, line breaks, and other formatting difficulties will be handled by a good SQL formatter, giving your code a tidy, comprehensible appearance. You can quickly and efficiently format your code using various free, premium SQL formatter tools.

Here is a list of what SQL Formatter can do:

  • Code that has been formatted by other people is easy to understand.
  • SQL makes finding and fixing problems in code and reviewing it easier and faster.
  • Collaboration is helpful when doing projects and is used to pass assignments from one team to another.

Features of SQL Formatters

It is used to make SQL statements look better. The code is formatted naturally by the formatter, and each function is based on a simple algorithm. The structure and style of the code are based on basic rules, which makes it easier to write SQL code.

When the code is complicated and has many layers, it is best to use SQL Formatter to keep track of it. It adds new links to break up the available order into visual blocks over time. By putting the blocks together, the SQL formatter changes the functional depth of the statement.

  • SQL formatter is made so that strict programming syntaxes can be run quickly.
  • SQL formatter is used to figure out how to use the horizontal space in the best way possible.
  • Formatter helps us keep the way things look lined up without having to use spaces of any width.

SQL Formatters Best Practices

Indentation: SQL is easier to understand because it looks more organized when you use tabs.

Indentation is considered one of the most important forms of SQL formatting. Correct indentation makes the code easy to read and understandable. It can be done using tabs and spaces, and mainly used indentation is to apply four spaces for every level of indentation.

This SQL server code uses three different kinds of indentation. None is. First, the Block is second, and Smart is third. Other text formats have different settings for how far apart lines should be.

Block Options SQL Formatters

  1. NONE: When we press the Enter key, the mouse cursor moves and goes to the start of the next line when the “None” option is chosen from the indentation.

  1. BLOCK: When the block option is chosen, press the enter key; the cursor in the next row comes to its first column.

  1. SMART: SQL’s default indenting style is SMART, which chooses your indenting style. The next step is to define tab space to make an indent.

Line Length

SQL statements can be very long, and putting them over multiple lines makes the code easy to read. But it is necessary to keep the length of the line under supervision. A line containing many words is tough to read on mobile or smaller screens. The maximum recommended size of the line is 82.


When you format a SQL query, capitalization means how you should or shouldn’t capitalize SQL tokens in your code. Some developers like to make all reserved keys uppercase, others like to make them lowercase, and some like mixing and matching. It’s all up to what you want.

Regular capitalization is very important for readability. In SQL, the keywords are written in capital letters, and the rest is written in lowercase letters.


Correct use of the whitespace improves the readability of the SQL, and using space after commas and around the operators is very necessary.


Comments can be used to describe intricate code. Using descriptive comments

in your code can aid in communicating its purpose and rationale to readers.
