Update data in temporary table with new records found with joins on other table - sql

Question

I have data in a temporary table and I need to update this with the new data found with other tables using joins. How can I change the second select to an update statement?
Can you please suggest how to do this?
Thank you
SELECT
sc.str_psn, sc.str_esn, sc.id_smartcard, sc.id_customer, st.str_statusdesc,
pax.str_title
INTO #temp
FROM Smartrack.dbo.Smartcard sc
INNER JOIN Smartrack.dbo.Customer pax on sc.id_customer = pax.id_customer
INNER JOIN SmarTrack.dbo.StatusType st ON sc.int1_cardstatus = st.int1_statustype
SELECT
t.str_psn , t.str_esn, t.id_smartcard, t.id_customer, t.str_statusdesc,
t.str_title, subpax.datAdded, tok.str_token_desc, subpax.ultTokenType
FROM #temp t
INNER JOIN (
SELECT p.id_Customer, u.id_TravelToken, u.ultTokenType, u.datAdded, u.ultTokenExpiry
FROM SmarTrack.dbo.Customer p
INNER JOIN SmarTrack.dbo.Smartcard s ON p.id_customer = s.id_customer
INNER JOIN SmartrackInterface.dbo.vwUltimateCardDetails u ON s.id_smartcard = u.id_smartcard
WHERE s.id_replacement_smartcard IS NULL
) subpax ON t.id_customer = subpax.id_CUstomer
INNER JOIN SmarTrack.dbo.TravelToken tt ON subpax.id_TravelToken = tt.id_traveltoken
INNER JOIN SmarTrack.dbo.TokenType tok on subpax.ultTokenType = tok.int2_tokentype

Answer 1

Your question is similar to this: Update records in table from CTE
Your can try the following method
with cte as(
SELECT
t.str_psn , t.str_esn, t.id_smartcard, t.id_customer, t.str_statusdesc,
t.str_title, subpax.datAdded, tok.str_token_desc, subpax.ultTokenType
FROM #temp t
INNER JOIN (
SELECT p.id_Customer, u.id_TravelToken, u.ultTokenType, u.datAdded, u.ultTokenExpiry
FROM SmarTrack.dbo.Customer p
INNER JOIN SmarTrack.dbo.Smartcard s ON p.id_customer = s.id_customer
INNER JOIN SmartrackInterface.dbo.vwUltimateCardDetails u ON s.id_smartcard = u.id_smartcard
WHERE s.id_replacement_smartcard IS NULL
) subpax ON t.id_customer = subpax.id_CUstomer
INNER JOIN SmarTrack.dbo.TravelToken tt ON subpax.id_TravelToken = tt.id_traveltoken
INNER JOIN SmarTrack.dbo.TokenType tok on subpax.ultTokenType = tok.int2_tokentype
)
Update #temp
Set #temp.id_customer in (Select distinct id_customer From cte)
