關於 SQL 格式化
常見 SQL 方言格式化與壓縮
Readable SQL makes joins, filters, grouping, and nested queries easier to review. Formatting does not prove that a query is valid for a specific database or safe to run, so use the dialect setting and then test in a controlled environment.
點樣用呢個開發者工具
- Choose the SQL dialect closest to the database that will receive the statement.
- Paste the query and format it, or minify it when a compact representation is needed.
- Review identifiers, parameters, joins, and comments manually before running the query elsewhere.
私隱同資料處理
SQL formatting runs locally in the browser. Remove credentials, customer values, and proprietary schema details from examples before sharing or pasting them.

常見問題
Does the formatter execute SQL?
No. It only parses and rearranges SQL text. Execution, permissions, query plans, and data safety must be checked in your database environment.
Why does dialect selection matter?
Reserved words, quoting, functions, and pagination syntax vary between MySQL, PostgreSQL, SQLite, and other engines.
Will comments and parameter placeholders be preserved?
The result depends on the parser and SQL shape. Always compare important comments and placeholders with the original query.
