    Untested, of course... 😉

    DELETE dbo.abn_extract

    FROM dbo.abn_extract E

    INNER JOIN dbo.ABN_File_Header H

    ON SUBSTRING(E.[Column 0], 1, 13) = H.Header_Id

    SQL Server is one of the few RDBMS's that have a FROM clause (2 actually) available... everyone else has to use correlated sub-queries. Lookup DELETE in Books Online for a better understanding of the statement.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
