Download free sample SQL files. These are database dumps containing structured data (Schema + Insert Statements). Use them to test database import tools, query performance, and SQL dialect compatibility (MySQL vs PostgreSQL).

STANDARD
Common Dialects

File Name Dialect / Structure Size Action
users_mysql.sql
MySQL / MariaDB		 Standard MySQL dump. Uses backticks (`) for identifiers. Creates a `users` table with 100 records. 5 KB Download
users_postgres.sql
PostgreSQL		 Strict SQL syntax. Uses double quotes (“) for identifiers and specific data types (SERIAL, TIMESTAMPTZ). 5 KB Download
lite_users.sql
SQLite Compatible		 Simplified syntax suitable for mobile/local DBs. No specific engine declarations. 4 KB Download

QA / STRESS
Relations, Injection & Bulk Data

Test Case Description Size Action
Relational (Users + Orders) Foreign Keys. Creates 2 tables linked by ID. Tests if your import tool respects referential integrity (import order). 10 KB Download
Injection Payload Data Valid SQL, but the data inside contains strings like '); DROP TABLE users;--. Tests security sanitization. 2 KB Download
100k Rows (Bulk Insert) Heavy dataset using Extended Inserts (1000 rows per query). Optimized for speed testing. 15 MB Download

Technical Specs: SQL Dumps

  • DDL vs DML: A complete dump contains DDL (Data Definition Language) to create tables (`CREATE TABLE`) and DML (Data Manipulation Language) to fill them (`INSERT INTO`).
  • Transactions: Good dumps wrap inserts in `START TRANSACTION` and `COMMIT` to ensure data integrity and speed up the import process.
  • MIME Type: application/sql or text/x-sql.

Frequently Asked Questions

Can I import the MySQL file into PostgreSQL?
Usually, no. MySQL uses backticks (`) for table names, while PostgreSQL uses double quotes (“). Also, some data types like `TINYINT` or `ENUM` behave differently. You need a specific dump for your database engine.
Why is the “Bulk Insert” file faster?
Instead of running 100,000 separate queries (which takes minutes), Bulk Inserts group them: `INSERT INTO users VALUES (1, ‘A’), (2, ‘B’), (3, ‘C’)…`. This reduces network overhead and index rebuilding time dramatically.

How to execute SQL files?

You need a DBMS (Database Management System) client. Do not use Notepad to edit large dumps.

  • DBeaver: The best free universal tool. It connects to SQLite, MySQL, Postgres, Oracle, and allows executing scripts easily.
  • MySQL Workbench: The official tool for MySQL. Great for visualizing schemas (ER Diagrams).
  • DB Browser for SQLite: A lightweight, portable app to open `.sql` or `.db` files instantly without a server.

Developer’s Corner: Run Script in Python

Use the standard sqlite3 library to execute a SQL dump in memory for quick unit testing.

# Python: Execute SQL Dump
import sqlite3# Create DB in memory (RAM)
conn = sqlite3.connect(‘:memory:’)with open(‘dump.sql’, ‘r’) as f:
script = f.read()
conn.executescript(script)
print(“Database imported successfully!”)
