Table Spool right before insert? - sql-server

Question

What I understand about SPOOL is to store data into a temporary table so SQL Server could use it when have CTE or other usage. Does that means SPOOL should appear in the middle of my execution plan?
With the query below(I put SELECT * here to make the query smaller), the SPOOL shows up between INSERT and CONCATENATION actions in my execution plan. Just wondering what does this SPOOL do? Cause it costs about 30% in my execution plan. Wondering if I can make the plan get rid of it.
Edit: Execution Plan uploaded

Answer 1

Soool is copy of data in temp db .
Query have cte used to create new cte so execution logic is getting complicated to solve the problem sql server need to create interim result set the same is visible in query plan as spool.

Answer 2

IMHO , there is no point in CTE where there is no filter or calculation
for example LK_ALL,you can directly use #DBNAME#.DBO.#TBL4# where req. it may or may not improve performance,but at least it reduce number of lines.
It is really tough to debug, whole query.
but see here instead of so many left join(BTW,if you can use inner join)
you can rewrite your query like this,
FROM STEP2
Inner/LEFT JOIN LK_ALL D1 ON (STEP2.G_BANKNO = D1.CD AND D1.FIELDNAME = 'G_BANKNO')
or (D2.FIELDNAME = 'G_CSTCTR' AND STEP2.G_CSTCTR = D2.CD )
or (D3.FIELDNAME = 'G_GLACCTNO' AND STEP2.G_GLACCTNO = D3.CD )
or (D4.FIELDNAME = 'G_GLACCTYP' AND STEP2.G_GLACCTYP = D4.CD )
or (D5.FIELDNAME = 'G_GLACCTINT' AND STEP2.G_GLACCTINT = D5.CD )
or (D6.FIELDNAME = 'T_RTTYP' AND STEP2.T_RTTYP = D6.CD )
or (D7.FIELDNAME = 'T_PMTTYP' AND STEP2.T_PMTTYP = D7.CD )
or (D8.FIELDNAME = 'T_NIDPMMD' AND STEP2.T_NIDPMMD = D8.CD )
or (D9.FIELDNAME = 'T_CAHSSS' AND STEP2.T_CAHSSS = D9.CD )
or ( D10.FIELDNAME = 'R_LOBCD' AND STEP2.R_LOBCD = D10.CD )
or ( D11.FIELDNAME = 'R_BRNCHCD' AND STEP2.R_BRNCHCD = D11.CD )
or ( D12.FIELDNAME = 'R_PRODCD' AND STEP2.R_PRODCD = D12.CD )
or ( D13.FIELDNAME = 'R_TYPCD' AND STEP2.R_TYPCD = D13.CD )
or ( D14.FIELDNAME = 'R_HPTYPCD' AND STEP2.R_HPTYPCD = D14.CD )
I hope those hard coded parameter are dynamic in real life
Also you can do like,
declare #From date= dateadd(day,-1,'2016-10-01')
declare #To int= DAY(DATEADD(D, 1, CONVERT(DATE, RP_DATA_DT)))
for millions of records temp table is better than CTE.
Also you can comment part of query to see the performance.
