本文介绍了用新的扭曲计算?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我感谢这个小组的帮助。我知道我已经在最后几周发布了很多内容,但是在我的工作中我被扔进了一个数据库项目 非常少的访问体验。没有其他员工知道 Access。我搜索了Google网上论坛,这有很多帮助,但 有些问题我找不到答案。在这个问题之后,我会尝试在团队中轻松取笑。 我还有一个问题,我一直试图解决,我希望你们能够 帮助我提出一些建议。我上周发布了这个问题,但是我已经让我的老板给了我另一个曲线球并且不得不修改 我想做什么。 我想为每条记录分配一个号码,该号码将成为运费 号码的一部分。我想要数字值计算,直到合同号 改变。然后,我希望这个号码回到1并再次开始计算 ,直到下一次合同变更为止。 我得到了这个建议。 /> DCount(" *,Label_Info,[Contract] =''"& [Contract]&"''和 [Label_Info]![ID]< ="& [Label_Info]![ID])+ 0 合同是合约编号,Label_Info是表格 合约号码被保留,adn ID是一个自动编号字段。 这很好用。我的新问题是我必须添加另一个名为 Packed_With的字段来覆盖其他框中打包的部分。 Packed_With 值将为C或W(包含或With)。我的大多数记录都不会包含C或W,但是如果我选择C,那么下一条记录将是W.我需要W记录才能获得与前一个相同的值。如果有超过1个部分,我可能还有下一个W值的。所以,我希望所有的W' 与C具有相同的数值,我想开始计算我在W之后剩下的。我知道我不是很好解释,所以这里是 另一个例子: 例如 合同1111111第1箱第2组数值:1 合同1111111第2箱第2组数值:2 合同1111111防滑1 of 1数值:3 合同1111111 C第1栏,共1页数值:4 合同1111111 W数值:4 合同1111111 W数值:4 合同1111111 W数值:4 合同1111111防滑1 of 1数值:5 合同1111111方框1的1数值:6 合同2222222方框1 of 2数值:1 合同2222222方框2 of 2数值:2 合同2222222防滑1 of 1价值:3 合同2222222捆绑1 of 2数值:4 合同2222222捆绑2 of 2数值:5 有没有修改DCount方法做我想要的方法?其他 建议也欢迎。 我真的很感激帮助。我正在努力学习。 Chad 解决方案 我们都不是。 这似乎有效对于我尝试过的几个案例: qryNumberToAssign: SELECT Label_Info.ID,Label_Info.Contract,Label_Info.Packed_With, Label_Info.Box,(SELECT Count(A.ID)FROM Label_Info AS A WHERE A.Contract = Label_Info.Contract And A.ID< = Label_Info.ID) - (SELECT 计数(Nz(A.Packed_With))FROM Label_Info AS A WHERE A.Contract = Label_Info.Contract And A.ID< = Label_Info.ID And A.Packed_With =' 'W'') AS NumberToAssign FROM Label_Info; 也许你可以把它转换成两个独立的DCount'。请注意,这个 方法要求第一个Contract项目中没有''W'' Packed_With所以请准备好让老板要求:-)。如果W的 是连续的,你真的想要尝试类似的东西: SELECT Label_Info.ID,Label_Info.Contract,Label_Info。 Packed_With, Label_Info.Box,(SELECT Count(B.ID)FROM Label_Info AS B WHERE B.Contract = Label_Info.Contract And B.Packed_With =''W ''AND B.ID< = Label_Info.ID AND Label_Info.ID> DMax(" ID"," Label_Info"," Contract = ''"& Label_Info.Contract&"''And Packed_With =''W''"))AS WsPreviousToThisNonW来自Label_Info; 即,DMax函数可以在DCount函数的Criteria 字符串中使用,以帮助获得只有你的老板可以想象的功能。 James A. Fortune 这是一个好主意。这个小小的SQL拼图很有趣,但它不是必需的。$ / b James A.

I know I''ve posted a lot here the lastcouple of weeks, but I was thrown into a database project at my work withvery little Access experience. No other employee knows anything aboutAccess. I''ve searched Google Groups, and that has been a lot of help, butthere are some questions that I just can''t find the answer to. I''ll try totake it easy on the group after this question.I have one more problem I''ve been trying to solve, and I hope you guys canhelp me out with some suggestions. I posted this question last week, but Ihave since had my boss throw me another curve ball and have had to modifywhat I wanted to do.I want to assign a number to each record that will be part of a shippingnumber. I want the number value to count up until the contract numberchanges. Then, I want the number to go back to 1 and start counting up againuntil the next contract change.I was given this suggestion.DCount("*","Label_Info","[Contract]=''" & [Contract] & "'' And[Label_Info]![ID] <=" & [Label_Info]![ID])+0With Contract being the contract number, Label_Info being the table thecontract number is held, adn ID being an autonumber field.This worked great. My new problem is I have to add another field calledPacked_With to cover parts that are packed in other boxes. The Packed_Withvalue is going to be C or W (Contains or With). Most of my records will notcontain either C or W, but if I pick C, then the next record will be W. Iwant the W record to have the same value as the previous. I might have yetanother W value next if there is more than 1 part. So, I want all the W''sto have the same number value as the C, and I want to start counting where Ileft off after the W. I know I am not explaining myself well, so here isanother example:For exampleContract 1111111 Box 1 of 2 Number Value: 1Contract 1111111 Box 2 of 2 Number Value: 2Contract 1111111 Skid 1 of 1 Number Value: 3Contract 1111111 C Box 1 of 1 Number Value: 4Contract 1111111 W Number Value: 4Contract 1111111 W Number Value: 4Contract 1111111 W Number Value: 4Contract 1111111 Skid 1 of 1 Number Value: 5Contract 1111111 Box 1 of 1 Number Value: 6Contract 2222222 Box 1 of 2 Number value: 1Contract 2222222 Box 2 of 2 Number value: 2Contract 2222222 Skid 1 of 1 Number value: 3Contract 2222222 Bundle 1 of 2 Number value: 4Contract 2222222 Bundle 2 of 2 Number value: 5Is there a way to modify the DCount method to do what I want? Othersuggestions are welcome also.I would really appreciate the help. I''m trying to learn as I go.Chad 解决方案Aren''t we all.This seemed to work for several of the cases I tried:qryNumberToAssign:SELECT Label_Info.ID, Label_Info.Contract, Label_Info.Packed_With,Label_Info.Box, (SELECT Count(A.ID) FROM Label_Info AS A WHEREA.Contract = Label_Info.Contract And A.ID <= Label_Info.ID) - (SELECTCount(Nz(A.Packed_With)) FROM Label_Info AS A WHERE A.Contract =Label_Info.Contract And A.ID <= Label_Info.ID And A.Packed_With = ''W'')AS NumberToAssign FROM Label_Info;Perhaps you can convert it into two separate DCount''s. Note that thismethod requires that the first Contract item not have a ''W'' inPacked_With so be ready for your boss to ask for that :-). If the W''sare contiguous and you really want to get fancy try something like:SELECT Label_Info.ID, Label_Info.Contract, Label_Info.Packed_With,Label_Info.Box, (SELECT Count(B.ID) FROM Label_Info AS B WHEREB.Contract = Label_Info.Contract And B.Packed_With = ''W'' AND B.ID <=Label_Info.ID AND Label_Info.ID > DMax("ID", "Label_Info", "Contract =''" & Label_Info.Contract & "'' And Packed_With = ''W''")) ASWsPreviousToThisNonW FROM Label_Info;I.e., the DMax function can be used inside a DCount function''s Criteriastring to help get functionality that only your boss can imagine.James A.
