SqlServer 创建服务器连接

--创建链接服务器 
    exec sp_addlinkedserver 'ITSV' , '' , 'SQLOLEDB' , '192.168.1.232' 
    exec sp_addlinkedsrvlogin 'ITSV' , 'false' , null , 'sa' , '********' 

--以后不再使用时删除链接服务器 
    exec sp_dropserver 'ITSV', 'droplogins' 

--执行存储过程
    --exec batch_import 'err' --测试报错

--存储过程传入参数，默认值
ALTER PROCEDURE [dbo].[batch_import]
    @ear_id varchar(20), @del_flag varchar(20) = null

--存储过程开事务

  BEGIN TRY
  SET XACT_ABORT ON;
  BEGIN TRAN

if(@ear_id='err')

  begin
  insert into os_report select TOP(1) * from os_report
  end

  COMMIT TRAN
  select '执行完成', @ear_id as ear_id
  END TRY
  BEGIN CATCH
  ROLLBACK TRAN
  select error_number() as error_number,error_message() as error_message,error_state() as error_state,error_severity() as error_severity, @ear_id as ear_id
  END CATCH
