    Try this... it's Adrian's original code with some conditions added...

    SELECT LEFT(raw_payload, CHARINDEX('+', raw_payload, 1)-1),

    CASE

    WHEN LEN(raw_payload)-LEN(REPLACE(raw_payload,'+','')) >= 2

    THEN

    CAST(SUBSTRING(raw_payload,

    CHARINDEX('+', raw_payload, 1) + 1,

    CHARINDEX('+', raw_payload, CHARINDEX('+', raw_payload, 1) +1) - (CHARINDEX('+', raw_payload, 1) + 1))

    AS FLOAT)

    ELSE NULL END,

    CASE

    WHEN LEN(raw_payload)-LEN(REPLACE(raw_payload,'+','')) >= 3

    THEN

    CAST(SUBSTRING(raw_payload,

    CHARINDEX('+', raw_payload, CHARINDEX('+', raw_payload, 1) +1) + 1,

    LEN(raw_payload) - CHARINDEX('+', raw_payload, CHARINDEX('+', raw_payload, 1) +1) + 1)

    AS FLOAT)

    ELSE NULL END

    FROM #SplitMe

    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.
