What is SQL formatting?

SQL formatting is the process of converting messy SQL code into a well-structured, easy-to-read format. By adding proper indentation, line breaks, and spacing, the code becomes easier to understand and maintain. This improves code readability and helps teams maintain consistent coding standards.

Which database dialects are supported?

We support multiple mainstream database dialects including: MySQL, PostgreSQL, Oracle PL/SQL, SQL Server (T-SQL), SQLite, MariaDB, TiDB, BigQuery, and standard SQL. Each dialect has specific syntax recognition for optimal formatting results.

Will my SQL code be uploaded to a server?

No. All SQL formatting is processed locally in your browser using JavaScript. Your code never leaves your device, ensuring complete data privacy and security. This makes our tool safe for formatting sensitive database queries.

How do I customize formatting options?

You can customize formatting options in the settings panel: choose indent size (2 or 4 spaces, or tab), select keyword case (uppercase, lowercase, or preserve original), set lines between queries, and select your target database dialect for optimal results.

What is SQL minification used for?

SQL minification converts formatted SQL code into a single line by removing extra spaces and line breaks. This reduces code size for transmission and storage, making it useful for embedded systems, API calls, and scenarios where minimal size is required.

Will formatted SQL change execution results?

No. SQL formatting only changes the display format of the code (indentation, spacing, line breaks). It does not affect the SQL semantics or execution results. Your queries will produce identical results before and after formatting.

Can it handle large SQL files?

Yes. Our tool is built on a high-performance parsing engine that can handle large stored procedures, complex queries, and multi-statement scripts. The processing happens locally in your browser, so performance depends on your device capabilities.

Is this tool free to use?

Yes, SQL Formatter is completely free to use with no registration required, no ads, and no usage limits. You can format unlimited SQL code without any restrictions or hidden fees.

关于SQL格式化的常见问题解答

什么是 SQL 格式化？

SQL 格式化是将杂乱的 SQL 代码转换为结构清晰、易于阅读的格式的过程。通过添加适当的缩进、换行和空格，使代码更易于理解和维护。

支持哪些数据库方言？

我们支持多种主流数据库方言，包括：MySQL、PostgreSQL、Oracle PL/SQL、SQL Server、SQLite、MariaDB、TiDB、BigQuery 等。

我的 SQL 代码会被上传到服务器吗？

不会。所有 SQL 格式化处理都在您的浏览器本地完成，代码永远不会离开您的设备，确保数据隐私安全。

如何自定义格式化选项？

您可以在格式化选项面板中自定义：缩进大小（2/4 空格）、关键字大小写（大写/小写/保持原样）、换行风格等。

SQL 压缩有什么用？

SQL 压缩将格式化的 SQL 代码转换为单行，去除多余空格和换行，减小代码体积，适用于需要传输或存储 SQL 的场景。

格式化后的 SQL 会改变执行结果吗？

不会。SQL 格式化只改变代码的显示格式，不影响 SQL 的语义和执行结果。

如何使用 SQL 语法验证功能？

将 SQL 代码粘贴到输入框后，系统会自动进行基本的语法检查，如发现错误会在输出区域显示提示信息。

支持处理大型 SQL 文件吗？

是的，我们的工具基于高性能解析引擎，可以处理大型存储过程和复杂查询，响应速度快。
