Sql2010 创建程序集

C# 建立数据库 CRL 项目  .Net 3.5

public  partial  class MyClr
{
    [Microsoft.SqlServer.Server.SqlFunction]
    public  static  SqlBoolean CLRFBitContains(string MyBigIntValue, int  Row)
    {
        // 在此处放置代码
        return  (new MyBigInt(MyBigIntValue) & MyBigInt.CreateByBitPositon( Convert .ToUInt32(Row))) == MyBigInt.Zero;
    }
}

　　数据库初始化:

exec  sp_configure 'show advanced options' , '1' ;
go
reconfigure;
go
exec  sp_configure 'clr enabled' , '1'
go
reconfigure;
exec  sp_configure 'show advanced options' , '1' ;

go
  ALTER  DATABASE  DB_Name set  TRUSTWORTHY on ;
go

　　数据库添加程序集:

create  assembly MyClr
from  'R:\MyApp\MyClr\MyClr\bin\Debug\MyClr.dll'
WITH  permission_set = Safe;

　　数据库添加函数映射

create  function  ClrFBitContains
( @val as  nvarchar(4000) , @RowIndex as   int  )
returns  bit
as
  external  name  MyClr.MyClr.CLRFBitContains  ;

　　

TestSql:

 select dbo.ClrFBitContains('F0F',11)
