SQL Query Writing & Tuning

In the Basic package:

• Up to 3 queries
• Executed and checked (PostgreSQL/SQLite)
• .sql file with comments
• Files: PDF, DOCX, Markdown and Queries (.sql)
• Human review: not included

Send your schema and the questions you need answered. GigBlend’s AI agent writes read-only SQL with sample data and the exact result each query should return. For PostgreSQL and SQLite we then run every query in a sandboxed database - on your own CREATE TABLE statements when they run as pasted - and deliver only if each one returns exactly the stated result; index recommendations are applied to the same schema and the query plans captured. MySQL / MariaDB and SQL Server queries cannot be run in our sandbox, so they are syntax-checked by a SQL parser only, and we say so on the delivery.

Outcome

A .sql file of checked queries and a report with notes, results and (Standard and Premium) query plans, as PDF, DOCX and Markdown.

Delivered as

PDF, DOCX and Markdown (varies by package)

Not included

INSERT/UPDATE/DELETE, schema migrations, stored procedures and triggers, connecting to your database, guaranteed performance gains.

Limitations

Read-only SELECT queries and CREATE INDEX recommendations only. Tested on small illustrative sample data, not your real data, so speed on your volumes is not measured. MySQL / MariaDB and SQL Server queries are syntax-checked, not executed. We never connect to your database.
