Database Access Information

Read-Only Mode: Safe for running `SELECT` queries on the main database. No data can be changed.

Read-Write Mode: Your personal sandbox for practicing all SQL commands (`CREATE`, `INSERT`, `UPDATE`, etc.). All non-`SELECT` queries automatically run here. Destructive commands like `DELETE` `DROP` `TRUNCATE` are disabled for safety.
