Usage

Once installed, you can use SQLfuzz to generate random data in your SQL tables. Here’s how you can do it for both MySQL and PostgreSQL:

MySQL

sqlfuzz -u username -p password -d database -h 127.0.0.1 -t table -n 100000 -w 100

PostgreSQL

sqlfuzz -u username -p password -d database -h 127.0.0.1 -t table -n 100000 -w 100 -P 5432 -D postgres

Understanding SQLfuzz: An Analogy

Think of SQLfuzz as a chef preparing a unique dish in a restaurant. Just as a chef might use various ingredients in different proportions to whip up delectable meals without compromising on flavor, SQLfuzz fills your SQL database with varied and randomized data, ensuring a rich and complex environment for testing! Where the chef ensures that all ingredients are available and measured correctly, SQLfuzz ensures that the right data is populated in the right tables with random variations to mimic real-world scenarios.

Available Flags

SQLfuzz comes with a variety of flags that allow you to customize its behavior:

  • -u: User for database connection
  • -p: Password for database connection
  • -d: Database name for database connection
  • -h: Host for database connection
  • -P: Port for database connection
  • -D: Driver for database connection (supported: mysql, postgres)
  • -t: Table for fuzzing
  • -n: Number of rows to fuzz
  • -w: Concurrent workers to work on fuzzing
  • -s: Seed value for reproducibility of data

Troubleshooting

If you encounter issues while using SQLfuzz, try the following troubleshooting tips:

  • Ensure your database is running and accessible from the host specified.
  • Verify that your credentials (username and password) are correct.
  • Check if the specified table exists in the database you’re targeting.
  • Make sure the port number is correct, especially for PostgreSQL.
