使用WITH的存储过程

Question

我是SQL的新手查询者，但我可以做一点工作，并且了解一些概念。我正在尝试编辑旧的IT经理编写的存储过程，但是不确定如何使用WITH语句。到目前为止，这是我要尝试的CREATE一个新的存储过程。

*USE [WYN]

GO

/****** Object:  StoredProcedure [dbo].[wynne_insurance_census_report]    Script Date: 9/12/2018 10:20:45 AM ******/

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

CREATE proc [dbo].[wynne_insurance_census_report] @DATEIN VARCHAR(8)

AS

with cte_emp (emp, nam, ssc, gen, brt, hd)

as

(SELECT a.EMPLOYID, rtrim(LASTNAME) + ', ' + rtrim(FRSTNAME), SOCSCNUM, GENDER, BRTHDATE, b.BENEFIT

from UPR00100 a left join UPR00600 b on a.EMPLOYID = b.EMPLOYID
where a.INACTIVE = '0' and b.INACTIVE = '0'
)

select nam, ssc, 
    case
    when gen = '1' then 'Male'
    else 'Female'
    end, 
    brt,
    zip,
    hd,

--Coverage Tier
(select BENEFIT
from upr00600) Coverage
