Referencing Results of Multiple Temporary Tables in SQL Server - sql-server

Question

I’m using SQL Server 2008
I have joins written something like the following, where the first join is encapsulated in a ‘With as’ statement so that I can name the output table as ‘A’ and then reference the ‘A’ resulting table in the next select and Join seen beneath it.
This works perfectly fine. What I would like to do then is reference that second table for another select statement and join, but when I try to wrap it in a ‘With as’ statement as well, the editor does not accept it as legitimate syntax for the second instance of 'With as'.
How can I subset resulting tables to reference in further select and join statements? I do not have permission to write to the database, so I can not create permanent tables in the database.
Thank you.
With A as
(
SELECT POL.[COMPANY_CODE]
,POL.[POLICY_NUMBER]
,POL.[STATUS_CODE]
,POL.ORIG_CLIENT_NUM
,TA.LINE
FROM [SamsReporting].[dbo].[POLICY] POL
Left join [SamsReporting].[dbo].[Transact] TA
ON TA.POLICY_NUMBER = POL.POLICY_NUMBER and TA.BASE_Account = 'B'
)
Select PM.POLICY_NUMBER
,A.[COMPANY_CODE]
,A.[POLICY_NUMBER]
,A.[Policy Status]
,eApp.SourceCode
From A
Left Join Web.dbo.Pmetrics PM on A.POLICY_NUMBER=PM.POLICY_NUMBER
Left Outer Join DDP.pol.eAppStaging eApp
on A.POLICY_NUMBER=eApp.PolicyNumber
where eApp.SourceCode = 'HAQ' or eApp.SourceCode = 'PLS'

Answer 1

Common Table Expressions (CTEs) can build upon each other as you would like. For example, you can do this:
WITH CTE1 AS (SELECT * FROM Table 1)
, CTE2 AS (SELECT * FROM CTE1)
, CTE3 AS (SELECT * FROM CTE2)
You only need the WITH statement for the first CTE. After that just use the CTE name, as in my example.
Hope that helps,

Answer 2

Sounds like a syntax issue to me. Google CTE (Common Table Expression) and review some examples of how they are formed.
With A as
(SELECT POL.[COMPANY_CODE]
,POL.[POLICY_NUMBER]
,POL.[STATUS_CODE]
,POL.ORIG_CLIENT_NUM
,TA.LINE
FROM [SamsReporting].[dbo].[POLICY] POL
Left join [SamsReporting].[dbo].[Transact] TA
ON TA.POLICY_NUMBER = POL.POLICY_NUMBER and TA.BASE_Account = 'B'),
B as (
Select PM.POLICY_NUMBER
,A.[COMPANY_CODE]
,A.[POLICY_NUMBER]
,A.[Policy Status]
,eApp.SourceCode
From A
Left Join Web.dbo.Pmetrics PM on A.POLICY_NUMBER=PM.POLICY_NUMBER
Left Outer Join DDP.pol.eAppStaging eApp
on A.POLICY_NUMBER=eApp.PolicyNumber
where eApp.SourceCode = 'HAQ' or eApp.SourceCode = 'PLS')
Select *
From B -- inner join some table
where some condition = 1
