LIMIT, TOP, FETCH FIRST

MySQL uses LIMIT to restrict rows. TOP and FETCH FIRST belong to other SQL dialects. Add OFFSET to paginate.

Examples
-- First 5 rows\nSELECT * FROM orders ORDER BY created_at DESC LIMIT 5;\n\n-- Offset + limit\nSELECT * FROM orders ORDER BY order_id LIMIT 10 OFFSET 20;
  • Use consistent ORDER BY with LIMIT for deterministic results.
  • Combine with keyset pagination for better performance on large datasets.

Practice as You Learn

Use the MySQL editor to run queries and adjust examples. Build confidence by experimenting with different WHERE clauses, JOINs, and aggregates.

Frequently Asked Questions

Do I need to install MySQL to learn SQL?

No. You can practice SQL using our online MySQL editor. Installing MySQL locally is recommended for deeper learning and real-world workflows.

What are the most common SQL commands?

The essentials include SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, and JOIN. Mastering these gives you a strong foundation.

How do I avoid slow queries?

Use proper indexes, filter with WHERE, and limit scanned rows. Review query plans with EXPLAIN and avoid SELECT *

Is MySQL different from SQL?

SQL is the language. MySQL is a database system that uses SQL. Syntax is mostly standard, with a few MySQL-specific features.
