SQL Formatter

SQL prettier and minifier

This SQL formatter allows you to beautify your queries, as well as minify them, meaning to compress them for optimized use. Whether you're working on simple or complex queries, this tool proves extremely useful in various use cases.

When you need to debug a large SQL query (automatically generated?), containing multiple joins or subqueries, it is often difficult to read. This tool lets you reformat the query to make it more readable and structured, thereby facilitating overall understanding.

The SQL Pretty tool greatly improves the readability of SQL queries by restructuring them according to clear presentation standards. This online editor helps you easily visualize SQL statements, including SELECT, UPDATE, INSERT, and DELETE commands. Thanks to this formatter, queries are organized hierarchically and more intuitively, even when they contain syntax errors.

Even if the query is invalid, the tool still formats your code, helping you to identify potential errors more quickly. This proves useful when working with long chains of queries that are difficult to manually parse.

You can also customize the formatting according to your preferences: set the indentation level, choose the case for SQL keywords (uppercase or lowercase), select the type of database, and decide whether to keep or remove comments in your code. It is also possible to choose a compact mode (useful for minimizing code size).

The reformatting is instantaneous, unlike GPT tools, which can sometimes have latency issues... Fortunately, this tool remains a valuable asset 🙂

What are the objectives of SQL formatting?

• Improve the readability of queries.
• Facilitate SQL code maintenance.
• Ensure consistency among developers.

Fundamental principles of SQL formatting

• Use uppercase for SQL keywords
  It is recommended to write SQL keywords such as SELECT, FROM, WHERE, and JOIN in uppercase. This helps distinguish them from column or table names, making queries easier to read and understand.
• Use indentation and line breaks
  To improve readability, each important clause in a query (SELECT, FROM, WHERE, etc.) should start on a new line. Additionally, use indentation to structure subqueries or nested conditions in a clear way.
• Use aliases for tables and columns
  Aliases are shortened names that simplify queries and reduce repetition. It is important to choose clear and meaningful aliases to avoid confusion.
• Add comments to explain complex parts
  Comments are essential for documenting SQL queries, especially the more complex sections. Remember to consider your colleagues! 🙂 Use comments to make your code more understandable to others.

By following these principles, your SQL queries will be more readable and easier to maintain.
