FROM estadistica_productividad_picking_rf

如果是SQL服务器，您可以尝试：

    SELECT SUM(CASE WHEN cant_pallets_completo = 0 
                    THEN cant_sku 
                    ELSE cant_pallets_completo END) AS 'volumen_de_pallets' 
    FROM estadistica_productividad_picking_rf 
    WHERE cd='faseSQL' AND c_emp_user_grua <> '' ;
