MySQL Export: How to Download Your MySQL Data and What It's Worth
This MySQL export guide shows how to download your data with MySQL's own tools, then what those records are worth. Get a quick estimate for your MySQL history, see what buyers pay more for, and learn how to measure and export it.
MySQL data is part of your company's databases and warehouses record. Operational databases and warehouses hold the structured record of how a product or business runs. Its value depends on years of history, how much real discussion and detail it holds, and which other systems you combine it with.
MySQL export: the official steps
How to download your MySQL data
- Run
mysqldump db_name > backup-file.sqlfor one database, ormysqldump --all-databases > all_databases.sqlfor the server. - For InnoDB tables, add
--single-transactionfor a consistent dump without blocking applications. - Use
--tabfor tab-separated data files or--xmlfor XML if a buyer wants flat files.
MySQL notes that mysqldump writes SQL statements that recreate the schema and data, that it needs at least SELECT on dumped tables (plus SHOW VIEW and TRIGGER for views and triggers), and it points to the MySQL Shell dump utilities for larger dumps.

Estimate your MySQL data
Why AI companies want MySQL data
Operational databases and warehouses hold the structured record of how a product or business runs. Buyers look for internal operational data you own, not your customers' records.
What makes MySQL data worth more or less
| Raises value | Lowers value |
|---|---|
| Internal operational tables with history | Mostly logs or raw telemetry |
| Clear schemas and documentation | Undocumented tables |
| Years of history | Snapshots with no history |
| Your own business data | Customer data you process for others |
What's removed or excluded
Names, emails, phone numbers, account numbers and other identifying details are removed by a privacy specialist before any buyer or lab sees the data. Anything you hold on behalf of clients is excluded from the license.
How to measure your MySQL data
Add data_length and index_length from information_schema.
Exporting the full history: Export with mysqldump.
How to sell or license it
- Don't delete anything. Keep the account active, including former employees.
- Note the size and history. Your total GB in MySQL, plus how many years you've used it.
- Get an estimate. Use the estimator above, or the full calculator to include your other systems.
- Request an offer. A direct buyer reviews a sample, prices it, and pays after anonymized delivery. Start with Polyshares, or compare buyers first.
Common questions
Can I sell my company's MySQL data?
Generally yes, if the company owns the account and the data is about its own operations. It's licensed with identifying details removed, and anything you hold for clients stays out.
How much is MySQL data worth?
It depends on history, detail and what else you combine it with. Use the estimator above for MySQL alone, or the full calculator to include every system.
Do I need to export MySQL before getting an offer?
Not to get an estimate. Buyers start from your intake answers and review a sample. If you're closing, export before you cancel, since deleted accounts usually can't be recovered.
Do I keep my data?
With a license, yes. You keep the business and the data, and the license covers defined material for a defined term.
