What is this?
You install the Database Engine (and optional features) with the SQL Server setup wizard or a command-line config. After install, the SQL Server Windows service must be running.
Why should you care?
Without a running engine, every T-SQL script fails. Teams pin a version (e.g. 2022 Developer) so everyone practices the same features.
See it live — copy this example
Run in SQL Server Management Studio (SSMS) or Azure Data Studio.
-- After install, verify the engine answers
SELECT name, state_desc FROM sys.databases;
-- Create the course database if missing
IF DB_ID(N'DataVerse') IS NULL
CREATE DATABASE DataVerse;What happened?
- First query proves the instance responds.
- CREATE DATABASE builds your database when it does not exist — your home for later lessons.
Practice next
- Install SQL Server Developer or Express from Microsoft.
- Confirm SQL Server (MSSQLSERVER or SQLEXPRESS) is Running in Services.
- Connect with SSMS and run the example.
- Run SELECT @@SERVERNAME;
- Create a second small database PracticeLab and drop it later.
Remember
Install the Database Engine, then verify with a query. Create your database as your practice database. Match instance name when you connect.
Developer laptops mirror prod major version
The team installs SQL Server 2022 Developer locally against Azure SQL 2022 features.
Outcome: Temporal tables and ledger demos work the same offline.
