Frequently asked questions

Which SQL dialects are supported?

The system includes Standard SQL, MySQL, MariaDB, PostgreSQL, SQLite, SQL Server, Oracle PL/SQL, BigQuery, Snowflake, Redshift, and Spark SQL.

Does formatting validate or execute my query?

No. It restructures source text using the selected dialect but does not connect to a database, check schemas, or execute any statement.

Does minification preserve quoted text?

Yes. The minifier preserves quoted strings and identifiers while compacting whitespace. Comment removal is optional.

What does the SQL summary check?

It counts statement separators, statement types, comments, and common parameter placeholders. It also highlights DELETE and UPDATE statements without a WHERE clause, plus DROP and TRUNCATE statements. These are review reminders, not a complete SQL safety analysis.

Can I format a SQL file?

Yes. Import a .sql or .txt file up to 1 MB, choose your formatting settings, and download the result as a new .sql file.
