T-SQL Table Valued Function to compare Semantic Versions

Semantic versioning (SemVer) is a standardized system for labeling software releases using a three-part number—major, minor, and patch—optionally followed by pre-release labels and build metadata. Comparing semantic versions is complex because it requires handling both numeric and string components, as well as special precedence rules for pre-releases and stable versions. SQL Server’s hierarchyid data type is ideally suited for comparing the numeric parts of semantic versions, enabling efficient and accurate ordering without the pitfalls of string comparison or manual parsing.
