Need Realistic Test Data Fast? How to Generate Random Numbers in SQL Server

Generating random numbers and populating SQL tables with sample data is a daily challenge for database developers, QA engineers, and data analysts. When you need realistic datasets for testing, validation, or experimentation, manual data creation quickly becomes inefficient — and error-prone.

SQL Server offers built-in functions to generate random numbers and values within specific ranges. Combined with automated data generation, this approach lets you create unbiased, representative datasets in minutes. It’s especially useful for testing database tools, validating business logic, and running experiments without risking production data.

This article walks through practical ways to generate random numbers in SQL Server, with clear syntax examples and use cases. It also demonstrates how dbForge Data Generator for SQL Server can automate the process, helping you populate tables with meaningful sample data faster and more consistently.
