Frequently Asked Questions

Find Quick Answers

What SQL formats does the DB Analyzer support?

The tool supports standard SQL (MySQL, PostgreSQL, SQLite syntax) and can parse CREATE TABLE, ALTER, INSERT, SELECT, and other common statements.

Is my SQL data stored on your servers?

No, all processing happens in your browser or temporarily in memory on our servers. No database contents are permanently stored.

Can I analyze large SQL files?

Yes, the tool can handle files up to 10MB. For optimal performance with very large files, consider splitting them into smaller chunks.

Does the tool execute my SQL queries?

No, this is a static analyzer that examines SQL structure and syntax. It does not connect to or execute queries against actual databases.
