๐ HierarchyId Data Type
The hierarchyid data type was introduced with SQL Server 2008. Itโs specifically designed to represent and manipulate hierarchical data.
Hierarchical data structures contain parent-child relationships, and hierarchyid provides an efficient way to store and query such data.
In the context of databases, both Azure SQL and SQL Server support this data type.
๐ Querying Hierarchical Data
Once youโve stored hierarchical data using hierarchyid, you can perform various queries:Finding Ancestors and Dependents: You can query for ancestors (parents) and dependents (children) of specific items.
๐ก Depth-Based Queries
Retrieve all items at a certain depth within the hierarchy.
๐ Benefits of Using HierarchyId
It simplifies querying hierarchical data, making it easier and faster.
The hierarchyid type is more aligned with .NET norms than SqlHierarchyId. Itโs designed to work seamlessly with Entity Framework Core (EF Core).
hierarchyid is a valuable tool for managing hierarchical data in .NET Core applications. ๐ If you have any specific questions or need further assistance, feel free to ask! ๐
