How to write SQL from plain English (without memorizing dialect quirks)

Step 1 — describe what you want to know

Open SQLFix and write your question in plain English. Be specific about the table, the filter, and the aggregation. For example: "total revenue per user who placed more than 3 paid orders in 2025." Specific wording tends to produce a more accurate query than a vague one.

Step 2 — paste a schema if you have one

The schema field is optional, but pasting your table and column names (e.g. users(id, name, created_at); orders(id, user_id, total, status)) helps SQLFix match real columns instead of guessing. If you do not have the schema handy, you can still submit the question and review the result.

Step 3 — pick your dialect

Select PostgreSQL, MySQL, SQLite, or BigQuery. Dialect matters: date functions, string functions, and quoting rules differ between engines. SQLFix writes the query in the dialect you chose, so the output is closer to something you can run as-is.

Step 4 — read the explanation, not just the query

SQLFix returns the SQL in a fenced block followed by a 2–3 sentence plain-English explanation. Read the explanation first. If the explanation does not match what you intended, rephrase your question — small wording changes can change the join or the filter significantly.

Step 5 — check the safety findings

Before copying, review the deterministic safety screen. It flags injection-prone construction, DROP/TRUNCATE without a guard, and UPDATE/DELETE that would touch every row. SQLFix can help you catch these patterns; it does not guarantee the query is correct, so still confirm the logic against your data.

An honest limit

This workflow can help you produce a readable first draft quickly. It does not replace understanding your own schema, and for any statement that writes or deletes data, a qualified reviewer should confirm it before it runs.

FAQ

How do I write SQL from plain English?

Describe your question in SQLFix, optionally paste your schema, pick a dialect (Postgres/MySQL/SQLite/BigQuery), read the plain-English explanation, and review the safety findings before copying the query.

Do I need to know SQL to use SQLFix?

No. SQLFix is built for people who can describe what they want in English but do not want to write the SQL by hand. Reading the explanation helps you learn, but you do not need prior SQL knowledge to start.

Why does the dialect choice matter?

Date functions, string functions, and quoting rules differ between PostgreSQL, MySQL, SQLite, and BigQuery. Picking the right dialect helps SQLFix produce a query that matches your engine's syntax.

How accurate is the generated SQL?

Accuracy depends on how clearly you phrase the question and whether you provide the schema. SQLFix can help you get a strong first draft, but it does not guarantee correctness — review the query and explanation before running it.

What should I check before running a generated query?

Confirm the tables, joins, and filters match your intent, and review the safety findings — especially for any UPDATE/DELETE. For anything that writes or deletes data, have a qualified reviewer confirm it first.

## Disclaimer

Disclaimer (decision-support, not a guarantee): SQLFix is a tool that helps you turn a plain-English question into a dialect-aware SQL query with a readable explanation and a deterministic safety screen. It is decision-support, not a guarantee that a query is correct, safe, or optimal, and it is not a replacement for a qualified database reviewer. Always review generated SQL — especially any statement that writes, deletes, or alters data — before running it against a production database.
