SQL Beautifier/Formatter

Tool Introduction

The SQL Beautifier/Formatter is an efficient and convenient online SQL code typesetting tool. Its core function is to transform messy, hard-to-read SQL statements into a clear, easy-to-understand format. With this tool, you can easily organize complex query statements, stored procedures, etc., significantly improving SQL code readability and maintainability.

This tool supports formatting user-input "Before Formatting" SQL code according to preset or custom rules, and displays the beautified result in real-time in the "After Formatting" area. Specifically, you can flexibly control the code's indentation level through the "Number of Spaces" parameter, which defaults to 4 spaces, to meet different coding standards and personal habits.

How to Use

1. Open the SQL Beautifier/Formatter tool page.
2. In the left "Before Formatting" input box, paste or manually enter the SQL code you need to beautify. This is a required field.
3. (Optional) In the "Number of Spaces" input box, enter your desired number of indentation spaces. The default value is 4. If you do not make any changes, the tool will use the default value for formatting.
4. The tool will automatically, or after you finish typing, display the formatted SQL code in the right "After Formatting" area. You can directly copy and use it.

• Q: What input formats are supported?
• A: This tool supports standard SQL syntax; DDL, DML, DCL, or TCL statements can all be formatted.
• Q: What is the output format?
• A: The output is beautified and typeset plain text SQL code, which can be directly copied and used in your editor or database client.
• Q: Can I customize indentation?
• A: Yes, you can freely set the number of indentation spaces using the "Number of Spaces" parameter to match your coding habits or team standards.
• Q: Does it support beautification for specific database dialects?
• A: This tool primarily beautifies based on general SQL syntax. For specific dialects and special functions of different databases (such as MySQL, PostgreSQL, Oracle, SQL Server), the beautification effect may vary.

Important Notes

• Input data must be valid SQL code. If the input SQL syntax is incorrect or incomplete, it may lead to formatting failure or unexpected results.
• This tool mainly focuses on code typesetting and indentation and will not modify the semantics of SQL statements. Please use it with confidence.
• For very complex SQL statements, deeply nested levels, or statements containing a large number of special characters, the formatting effect may not be ideal, and manual fine-tuning is recommended.
• Before applying the formatted SQL code to a production environment, it is recommended to verify it in a test environment to ensure that its functionality and performance are not affected.
