Question

I have this code so far:

DECLARE @AddressIDS TABLE
(
    AddressID int
)

INSERT INTO Address(Street1, City, StateCode, ZipCode)
OUTPUT inserted.AddressID INTO @AddressIDS
SELECT Street1, City, StateCode, ZipCode
    FROM Contact

Now I need to put the IDs in the @AddressIDS back into the AddressID of the Contact table.

This better describes what I’m trying to do in TSQL:

Answer 1

Assuming Street1 + City + StateCode + ZipCode is unique, or that multiple contacts can share the same AddressID, then you don’t need to suss out the AddressID values in an intermediate step. You can just perform your insert into Address and then:

UPDATE c 
  SET AddressID = a.AddressID
  FROM dbo.Contact AS c
  INNER JOIN dbo.Address AS a
  ON c.Street1 = a.Street1
  AND c.City = a.City
  AND c.StateCode = a.StateCode 
  AND c.ZipCode = a.ZipCode;
