The Definitive Guide to SQL Formatters

Indentation: Using tabs makes SQL look more ordered, which makes it easier to understand. One of the most crucial aspects of SQL formatting is indentation. Code that is properly indented is much easier to read and comprehend. The most common method of indentation, which involves utilizing tabs and spaces, is to add four spaces between each level of indentation.

Indentation comes in three forms in this SQL Server code. Absolutely not. The Block comes in at number two, followed by Smart. The spacing between lines can be customized in several text formats.

None: When we select “None” from the indentation menu, the mouse pointer travels to the beginning of the next line whenever we hit the Enter key.

Block: When you choose “block,” hit enter to move the cursor to the first column of the following row.

SMART: The SMART indentation style is SQL’s default and is used to choose the indentation style. Defining tab space to create an indent is the subsequent step.

Line Length

Splitting out lengthy SQL statements across numerous lines makes the code much easier to read. However, the length of the line must be closely monitored. It is difficult to read a lengthy line on a mobile device or a smaller screen. The line should not be larger than 82.


The capitalization of SQL tokens in code refers to the proper and incorrect ways to capitalize them when formatting an SQL query. There are developers who like all reserved keys to be uppercase, developers who prefer all reserved keys to be lowercase, and still others who favour a combination of the two. It’s totally up to you.

For readability, regular capitalization is crucial. Capitalization is used for keywords in SQL, while lowercase is used for everything else.


Properly utilizing whitespace enhances SQL readability; specifically, space is required immediately following commas and immediately around operators.


Complex code can be described using comments. By means of elucidative remarks in your code can help readers understand its goal and reasoning.
