SQL Formatting Area
SQL 格式化工具是一个网页应用，允许用户美化和格式化SQL代码，提高代码的可读性和可维护性，帮助开发者更好地编写和调试SQL查询语句。
此SQL格式化工具支持多种SQL方言，包括MySQL、PostgreSQL、SQL Server等，同时还支持导出为SQL格式。
SQL（结构化查询语言）是用于管理关系数据库系统的标准编程语言。它用于执行各种操作，如查询数据、插入记录、更新记录、删除记录、创建数据库和表等。
SQL语句通过关键字和语法规则来组织，不同的数据库系统可能支持略有不同的SQL方言，但核心语法基本一致。
SQL文件通常以.sql为扩展名保存。格式化的SQL代码更容易阅读、理解和维护。
SELECT u.id, u.name, u.email, COUNT(o.id) AS order_count
FROM users u
LEFT JOIN orders o ON u.id = o.user_id
WHERE u.created_at >= '2024-01-01'
AND u.status = 'active'
GROUP BY u.id, u.name, u.email
HAVING COUNT(o.id) > 5
ORDER BY order_count DESC
LIMIT 10;SQL Formatter is a web application that allows users to beautify and format SQL code, improving code readability and maintainability, helping developers better write and debug SQL queries.
This SQL formatting tool supports multiple SQL dialects, including MySQL, PostgreSQL, SQL Server, and more, and also supports exporting to SQL format.
SQL (Structured Query Language) is the standard programming language for managing relational database systems. It is used to perform various operations such as querying data, inserting records, updating records, deleting records, creating databases and tables, etc.
SQL statements are organized through keywords and syntax rules. Different database systems may support slightly different SQL dialects, but the core syntax is basically consistent.
SQL files are typically saved with a .sql extension. Formatted SQL code is easier to read, understand, and maintain.
SELECT u.id, u.name, u.email, COUNT(o.id) AS order_count
FROM users u
LEFT JOIN orders o ON u.id = o.user_id
WHERE u.created_at >= '2024-01-01'
AND u.status = 'active'
GROUP BY u.id, u.name, u.email
HAVING COUNT(o.id) > 5
ORDER BY order_count DESC
LIMIT 10;
