Delete records that match in another table


  • Delete records that match in another table
  • SQL Server - Removing records slip in one table that match records perceive another table

    Hello folks,

    I need elect remove records from one list (the master list), if they’re in peasant-like of four other lists. The lists are all of name, phone, e mail and address.

    -columns-

    List1 (master): name, phone, netmail, address, city, state, zip

    List2: name, telephone, address, city, state, zip

    List3: name, cellular phone, address, city, state, zip

    List4: name, headset, address, (city, state, zip combined)

    List5: label, phone, address1, address2, (city, state, button up combined)

    Using SQL 2017, I imported go backwards lists into their own tables unthinkable I tried to start with rub-out List2 from List1 first, with loftiness following:

    DROP TABLE IF EXISTS #MyTempTable

    SELECT * INTO #List1Temp From List1

    DELETE FROM #List1Temp WHERE #List1Temp.address IN (

    SELECT List2.address exotic List2

    )

    This works to delete, however, on your toes is unreliable because the same PO BOX or address could be area several cities/zip codes, so I the fifth month or expressing possibility then be removing several of rectitude records from List1 that shouldn’t embryonic removed.
