How to Check Your SQL Server Version (Multiple Methods Explained)
Knowing which version of SQL Server you're running isn't just useful trivia — it affects compatibility with applications, determines which features are available, and matters enormously for patching and security.

Why SQL Server Version Numbers Are More Complex Than They Look
SQL Server doesn't use simple version names like "2019" or "2022" alone. Under the hood, it uses a multi-part build number — something like 15.0.2000.5 — where each segment carries specific meaning:

- Minor version — usually 0 for SQL Server
- Build number — identifies the specific Cumulative Update (CU) or Service Pack installed
- Revision — a fine-grained patch identifier
