SQL Server .NET Integration

PERFORMANCE:

CLR functions that are computing-intensive and that do not perform data access are better written in managed code

Managed code can significantly outperform cursor-based aggregation

Managed STVFs perform better than comparable extended stored procedure implementations

CREATE:
