家长/子女关系/访问2010

本文介绍了家长/子女关系/访问2010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 我已经开始创建一个数据库（截至目前只有一个表）。 数据库用于存储有关技术要求的信息。在一个行业中。 每行对应一个要求。它包含有关该特定要求的描述，验证方法等信息。 有一个字段，RID和（要求ID）。 还有两个字段（父母，儿童），用于表示这些技术要求之间的父/子关系。 我使用查找向导作为数据类型这两个字段（父母，孩子）。 它使用户能够查看所有行（要求）的RID列表，并为父母（或孩子）选择多个值。 换句话说，有一个要求列表，您可以选择哪些要求是其他人的父母。 现在这就是我想做的事情： 我想启用一些自动互惠。 当用户选择Requirement 1作为Requirement 2的父项时。我希望Access在children中自动显示RID 2。需求的领域1. 换句话说，我不希望用户在指定父母/子女关系时做两次。 我希望我已经清楚/如果没有我可以进一步解释。 ，如果需要，我会创建多个表。I have started creating a database (There is only one table as of now).The database is meant to store information about "technical requirements" in an industry.Each row corresponds to one requirement. It contains information such as description, verification method, etc regarding that specific requirement. There is a field, "RID" (Requirement ID).There are also two fields ("Parents", "Children") that are intended to indicate the parent/child relationship between these technical requirements. I used the lookup wizard as "datatype" of these two fields (Parents, Children).It gives the user the ability to see the list of RIDs of all rows (requirements) and choose multiple values for parents (or children).In other words, there is a list of requirements and you can choose which requirements are parents of others. Now here''s what I would like to do:I want to enable some automatic reciprocity.When the user chooses Requirement 1 as parent of Requirement 2. I want Access to automatically show RID 2 in the "children" field of Requirement 1. In other words I don''t want the user to do everything twice when designating parent/child relationship. I hope I have been clear/ if not I can explain further.also, I will create more than one table if need be.推荐答案 展开 | 选择 | Wrap | 行号 这篇关于家长/子女关系/访问2010的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
