我遇到了一个相当奇怪的问题。我在SQL Server中有如下行：
Row number ITEMTYPE LIFECYCLEPHASE DESCRIPTION ITEMCATEGORY size PRODUCTLINES REV REVINCORPDATE REVRELEASEDATE EFFECTIVITYDATE SHIPPABLEITEM EXCLUDEFROMROLLUP COMPLIANCECALCULATEDDATE OVERALLCOMPLIANCE ITEMGROUPS MODELREF COMMODITY list07 text13 text12 text07 text01 CREATEUSER date01 list10 list09 list13 list24 text17 text24 text25 multiList01 multiList04 list17 numeric01 list03 list06 list25 list14 numeric03 numeric02 text21 list15 text11 text19 text20 date02 multiList02 list01 multiList03 list19 list20 text02 multiList05 list21 list22 text23 text03 text04 text05 money02 list12 list16 list11 list18

当我取消此行时。它应该显示66行和3列，如果使用下面的查询来取消上面提到的行。

我已经在2012年的实例和2008年的实例中测试了上述情况。在2012年，结果集符合预期，但在SQL Server 2008实例中忽略了所有具有空值的列。
2012年的结果是：

在这两种情况下，有谁可以告诉我这种差异背后的原因。我完全迷失在这一个。
