Question 1

What SQL dialects does this formatter support?

Accepted Answer

This formatter supports standard SQL syntax that is common across MySQL, PostgreSQL, SQLite, and SQL Server. It handles SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, ALTER TABLE, JOINs, subqueries, and common SQL functions.

Question 2

Does this formatter change the query logic?

Accepted Answer

No. The formatter only changes whitespace and keyword casing for readability. The query logic, table names, column names, and values are preserved exactly.

Question 3

Can I use this for stored procedures or complex queries?

Accepted Answer

Yes. The formatter handles complex queries with multiple JOINs, subqueries, GROUP BY, HAVING, ORDER BY, and UNION clauses. Extremely complex stored procedures with procedural logic (IF/BEGIN/END blocks) may produce partial formatting.

Question 4

Are SQL keywords converted to uppercase?

Accepted Answer

Yes. SQL keywords are normalized to uppercase (SELECT, FROM, WHERE, etc.), which is the conventional style used by most SQL style guides and database tools.

Question 5

Is my SQL query sent to any server?

Accepted Answer

No. All formatting happens entirely in your browser with JavaScript. Your SQL queries never leave your machine.
