    Is there any other way of writing this query ?

    SQL Server 2008 R2

    LEFT OUTER LOOP JOIN PART_LIST p1 ON e.COLUMN3 = p1.CODE

    AND p1.LIST_TYPE = 'PART_TEST_TYPE'

    AND p1.LANGUAGE = 'en-US'

    LEFT OUTER LOOP JOIN PART_LIST p2 ON e.SOURCE1 = p2.CODE

    AND p2.LIST_TYPE = 'SOURCE_TYPE'

    AND p2.LANGUAGE = 'en-US'

    LEFT OUTER LOOP JOIN PART_LIST p3 ON e.SOURCE2 = p3.CODE

    AND p3.LIST_TYPE = 'SOURCE_TYPE'

    AND p3.LANGUAGE = 'en-US'

    LEFT OUTER LOOP JOIN PART_LIST p4 ON e.STATUS = p4.CODE

    AND p4.LIST_TYPE = 'PART_STATUS'

    AND p4.LANGUAGE = 'en-US'

    Yes. And EAV's aren't necessarily the "horrible problem" that many make them out to be. I just can't advise you because I don't know what the rest of the query does because you've left it out.

    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.
