How to Merge SQL (3 Steps)

  1. Choose your SQL files. Select two or more .sql files in the order they should run.
  2. Merge. The files are concatenated so every statement keeps its place.
  3. Download the merged .sql file. Run the combined script against your database.

In short: this page is best for a quick, small file. For large files or batch jobs, use the TextMerger desktop app — it also ships a command line for scripts and scheduled runs.

What to Know About SQL

  • Statements keep their original order, so dependencies are respected.
  • Semicolons and comments are preserved; a newline is added between files.
  • Make sure all files target the same database and schema.
  • The free tool merges files up to 10 MB each; use the desktop app for larger dumps.

Frequently Asked Questions

Can I run the merged script in one transaction?

Yes, wrap the merged statements in BEGIN and COMMIT in your client if you need all-or-nothing execution.

What if two files create the same table?

The statements are kept in order, so the last CREATE or INSERT wins. Remove duplicates before merging if that is a problem.

Is my dump uploaded?

No, the merge happens in your browser.
