How to Re-Run a Previous Query

Instead of retyping complex SQL statements every time, the Nobregas MySQL Panel makes it easy to re-run queries efficiently. The query editor retains your text while you stay on the page, and you can use keyboard shortcuts for rapid execution.

Re-Running the Current Query

The fastest way to re-run a query is to keep it in the editor and execute it again:

1. Log in at mysql.nobregas.org.
2. Go to SQL Query in the top navigation bar.
3. Your previous query text remains in the editor if you have not navigated away.
4. Click Execute or press Ctrl+Enter to run it again.

Modifying Before Re-Running

You do not have to re-run the exact same query. Edit the text in the editor before executing:

• Change filter conditions — Adjust WHERE clauses for different data.
• Modify column selections — Add or remove columns from a SELECT.
• Update values — Change INSERT or UPDATE values for new operations.
• Add LIMIT — Restrict result sets for faster testing.

Running on a Different Database

To run the same query on a different database:

1. Keep the query text in the editor.
2. Change the database dropdown to a different database.
3. Click Execute.

This is useful for running the same query across staging and production environments.

Using Ctrl+Enter for Speed

Press Ctrl+Enter (or Cmd+Enter on Mac) to execute the query without clicking the button. This keyboard shortcut speeds up iterative query development significantly.

Practical Tips

Keep a Local Query File

Save frequently used queries in a local .sql file. When you need to re-run one, copy it into the editor and execute:

-- Monthly active users
SELECT COUNT(*) FROM users WHERE last_login > DATE_SUB(NOW(), INTERVAL 30 DAY);

-- Revenue by product
SELECT product_name, SUM(total) FROM orders GROUP BY product_name ORDER BY SUM(total) DESC;

Iterate on Complex Queries

Building a multi-join query? Run a version, check results, tweak it in the editor, and run again. The editor keeps your text between executions so you can refine iteratively.

Use Comments to Label Queries

Add SQL comments (--) to remind yourself what each query does, especially when copying from a local file.
