Thanks for the article but it seems that the link is not working.
CreateAssemblyAndAggregate.sql
Also when I try to create the procedure below I get an error. I named the dll MedianSQLSERVER
Error Message:
Msg 6505, Level 16, State 1, Procedure Agg_Median, Line 1
Could not find Type 'Agg_Median' in assembly 'MedianSQLServer'.
CREATE PROCEDURE Agg_Median
AS
EXTERNAL NAME [MedianSqlServer].[Agg_Median].[Accumulate]
--Assembly.type.
Thank you
