Schema grounding
Ask the model to list assumptions about table names, join keys, date columns, deleted rows, time zones, and event definitions.
🤖 SQL query prompt builder with safety checks
SQL Query Builder Prompt Generator
By Omellody Editorial Team · Published · UpdatedUse this existing Omellody prompt utility to convert a reporting question into a safe SQL drafting prompt with schema context, joins, filters, expected rows, performance review, and read-only constraints. The builder runs locally in your browser and does not send project details to Omellody.
Interactive prompt builder
Replace the examples with sanitized project details. The generated prompt updates locally in your browser.
Act as a senior engineer and careful reviewer. Help me create a SQL query design plan from the real context below.
Project context: {context}
Stack or tools: {stack}
Goal: {goal}
Constraints: {constraints}
Return these sections:
1. Direct recommendation with assumptions called out.
2. Inputs needed before acting and questions that block a reliable answer.
3. Decision table: option or hypothesis, evidence needed, risk, next action.
4. Step-by-step workflow with safe checks first.
5. Security, privacy, reliability, and maintainability review.
6. Tests, examples, or validation cases before merge or publication.
7. Rollback, escalation, and owner handoff plan.
8. Final checklist.
Rules: use only supplied facts, mark unknowns, avoid secrets or private data, do not invent undocumented behavior, and explain how to verify the result.

Prompt formula and variables
Formula: Business question + database engine + relevant tables + grain + filters + privacy limits + expected output + validation checks.
| Variable | What to enter |
|---|---|
{context} | Add specific, sanitized context details. If unknown, write the assumption explicitly. |
{stack} | Add specific, sanitized stack details. If unknown, write the assumption explicitly. |
{goal} | Add specific, sanitized goal details. If unknown, write the assumption explicitly. |
{constraints} | Add specific, sanitized constraints details. If unknown, write the assumption explicitly. |
Read-only guardrails
Require SELECT-only output, row limits for samples, no PII, and no mutation statements unless explicitly reviewed by a human owner.
Validation plan
Request sanity checks against known totals, duplicate detection, null handling, timezone windows, and explain-plan performance notes.
Output review table
| Check | Pass condition | Fix if weak |
|---|---|---|
| Grounding | The answer distinguishes facts, assumptions, and unknowns. | Add source snippets, example inputs, or explicit non-goals. |
| Safety | No secrets, customer data, account identifiers, or destructive commands are requested. | Sanitize examples and ask for read-only checks first. |
| Actionability | The plan includes concrete steps, owners, tests, and rollback or review criteria. | Request a checklist with evidence and stop conditions. |
| Verification | The output can be tested with unit cases, logs, traces, fixtures, or source-of-truth docs. | Add expected results and failure examples before using it. |

FAQ
What should a SQL query prompt include?
Include the business question, database engine, table schemas, join keys, date range, grain, filters, expected columns, privacy limits, and validation checks.
Can I paste table schemas into AI?
Use sanitized schemas without private data, credentials, internal hostnames, or customer records.
How do I reduce wrong joins?
Provide primary keys, foreign keys, sample row shapes, grain, and definitions for active, paid, churned, or converted users.
Should AI-generated SQL run directly in production?
No. Review the query, run it read-only in a safe environment, check row counts, and inspect the plan before use.
