sqlserver 中調用 DLL

1. 開啓數據允許clr

EXEC sp_configure 'clr enabled' , '1'; --0代表不允許，1代表運行

RECONFIGURE; 

2，創建clr

CREATE ASSEMBLY HashCodeDLL FROM 'D:\solf\Dll\UrlCode.dll'

3.創建函數

create FUNCTION [dbo].[HashCode](@InputString [nvarchar](50))
RETURNS [bigint] 
WITH EXECUTE AS CALLER
AS 
EXTERNAL NAME [HashCodeDLL].[UrlCode.Utils].[Hash]
