推荐答案
您可以在查询设计器中扩展每个关系.下面，我在查询设计器中的QuoteLines表上创建一个过滤器，该过滤器与我的Quotes表有关系，而我的Quotes表又与我的RepFirms表有关系，而我的RepFirms表又与我的InsideSalesReps表有关系.您可以过滤与任何链接表相关的任何数据.
You can expand each relationship in the query designer. Below I am creating a filter in the query designer on my QuoteLines table which has a relationship to my Quotes table which has a relationship to my RepFirms table which has a relationship to my InsideSalesReps table. You can filter on any data that is related to any of the linked tables.
