关于变量

YY_TEST.dbo.gh_ghzdk 因为这个是接口数据库里边的,名字有可能会改变,在存储过程里边用到6次
问题1:能否用一个变量代替,只需要在开始的时候赋值就行,该怎么写?
问题2:如果可以,那么这个变量也可以通过 存储过程参数 有程序提供对吗?

SQL code

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[P_AppointPercent]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure [dbo].[P_AppointPercent]
GO

SET QUOTED_IDENTIFIER ON 
GO
SET ANSI_NULLS ON 
GO
