MS-Access中的排序
我想在MS Access中对数据进行排序，为此我使用了一个查询。我的表格中的数据如下所示：MS-Access中的排序,ms-access,ms-access-2007,Ms Access,Ms Access 2007,我想在MS Access中对数据进行排序，为此我使用了一个查询。我的表格中的数据如下所示： RadButtonNo ------------------- AA001056 AA001579 B000049 AA001261 AA001158 AA001108 AA001166 AA001165 AA001164 AA001163 AA001162 对于我的输出，我首先想要的数据将只是由
RadButtonNo

WHERE (((TableApron.Lost)="N" Or (TableApron.Lost)=[@Lost])

有人能解决这个问题，让它产生我想要的输出吗 您可以使用以下两个功能：

通过在条目后面添加一个或多个数字对条目进行分组。对那个新领域进行排序。我在这里使用一个带所有z和额外z的值来排除一个真正的z条目
SELECT RadButtonNo
from tbl
order by IIF(RadButtonNo like "*#*", "zzzzzzzzz" & RadButtonNo, RadButtonNo)

到底是什么问题？请重新阅读并编辑您的问题，这很难理解。@Andre451我编辑了这个问题，您能理解吗？字段的正常排序将作为您的示例进行排序，那么您有什么问题吗？@Gustav我希望先从字符串A短到Z，然后从A（如1,2等数字）开始示例-
