Query Sandbox
A query sandbox is a restricted execution environment where queries run under strict limits—on permissions, runtime, and resources—so that no query, however wrong, can damage the database or the data.
In Depth
A sandbox assumes queries will sometimes be bad and makes badness harmless. Typical restrictions: read-only permissions (writes are impossible), statement timeouts (a runaway query gets killed instead of saturating the server), row limits (no accidental million-row exports), and an allowlist of permitted operations. Sandboxing matters most when query authors are not experts—exactly the situation with self-service and AI-generated SQL, where the volume of queries goes up and the average scrutiny per query goes down. With a proper sandbox, the worst case shifts from "incident" to "unhelpful result", which is what makes broad data access safe to offer at all.
How AI for Database Helps
AI for Database constrains execution by default—queries are validated against your schema and run read-only, so exploration carries no risk to your data.

Read-Only Mode
Read-only mode is a safety configuration in which a tool or database connection can run SELECT queries to read data but is blocked from any operation that modifies it—no INSERT, UPDATE, DELETE, or schema changes.
Query Validation
Query validation is the process of checking an AI-generated SQL query for correctness and safety—verifying it references real tables and columns, parses cleanly, and stays within allowed operations—before it runs.
AI Guardrails
AI guardrails are the technical constraints placed around an AI system that limit what it can do regardless of what it is asked—in database tools, controls like read-only execution, query validation, schema-only context, and operation allowlists.
Role-Based Access Control
A security model that restricts database access based on user roles and permissions within an organization.
