sqlserver 中调用 DLL

1. 开启数据允许clr

EXEC sp_configure 'clr enabled' , '1'; --0代表不允许，1代表运行

RECONFIGURE; 

2，创建clr

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

3.创建函数

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