嵌套多层查询

<div><span style="color: rgb(51, 51, 51); font-family: Arial; font-size: 14px; line-height: 26px;">set ANSI_NULLS ON</span></div>
<p style="color: rgb(51, 51, 51); font-family: Arial; font-size: 14px; line-height: 26px;">set QUOTED_IDENTIFIER ON
go
<p style="color: rgb(51, 51, 51); font-family: Arial; font-size: 14px; line-height: 26px;">
--得到XX表的信息,由于许多列都需要绑定D_Type_Detail,所以进行多层嵌套查询
ALTER proc [dbo].[Proc_SelectMateriel]
as
select t3.*,ztd3.TypeDetailName as UseStateName
from

from
