How to Insert Multiple Rows using a WHILE Loop in SQL Server | DBMS Tutorials | Part 23

Welcome to Part 23 of the Database Systems series! In our previous lectures, we looked at manual INSERTS and bulk loading data from flat files. But what if you are building a brand-new database and need to instantly generate hundreds of rows of realistic dummy data for testing purposes? In this lecture, we bring traditional programming logic directly into SQL Server. We will explore how to use the T-SQL WHILE loop to automate data entry, allowing us to populate tables programmatically in milliseconds. 📌 In this video, you will learn: The T-SQL WHILE Loop: Understanding the syntax of DECLARE, BEGIN, and END. Dynamic Data Generation: How to use mathematical operators (like modulo) and built-in functions to rotate through variables automatically. Performance Testing: Why generating dummy data is a critical skill for Database Administrators (DBAs) testing query speeds. Practice Assignment: Open SSMS and create a "Products" table. Write your own WHILE loop script to automatically generate 50 unique products, using T-SQL functions to assign random prices or alternating categories! #SQLServer #TSQL #DatabaseDesign #LearnSQL #ComputerScience #DBMS #ProgrammingLoops #DataGeneration
