Why Use Our SQL Formatter?
Frequently Asked Questions
Does the formatter support stored procedures and PL/SQL?
The formatter handles standard SQL statements including SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, and common procedural extensions. Complex dialect-specific procedural code may have limited support depending on the SQL dialect selected.
Will formatting change the behavior of my SQL query?
No. Formatting only changes whitespace, indentation, and letter case of keywords. The logical structure and execution behavior of your query remain exactly the same.
Can I format multiple SQL statements at once?
Yes. Paste multiple SQL statements separated by semicolons and the formatter will beautify each one individually, maintaining proper separation between statements.
