Using DAX to create a date dimension in Power BI 使用DAX在Power BI中创建日期维度 If the dataset that we are working on comes from a SQL database, then it is ideal that we can create a small date dimension table in that database itself. However, if the source is not an SQL database...
DateDimension = CALENDAR(MIN(‘Stock‘[PurchaseDate]), MAX(‘Invoices‘[InvoiceDate])) 或者,你可能更喜欢日期维度通过全年的数据,在这种情况下,公式可以这样创建表: DateDimension = CALENDAR(STARTOFYEAR(MIN(‘Stock‘[PurchaseDate])), ENDOFYEAR(MAX(‘Invoices‘[InvoiceDate]))) 这个公式扩展了DAX的计...

In the data source, there are two tables. The fact table contains three months sales data for the period from January 2007 to March 2007 and the dimension table, Date, stores the date information for all year 2007. We can write the below DAX measure to calculate the year-to-date sales ...
Dimension tables describe business entities---the things you model. Entities can include products, people, places, and concepts including time itself. The most consistent table you'll find in a star schema is a date dimension table. A dimension table contains a key column (or columns) that ...
我们知道,Power BI 的tabular模型仅允许由单个字段定义的关系,两张表中如果想对多个字段建立关系,也只能是虚线的未激活的关系,当激活了该关系时,另一个关系相应地就成了未激活。 所以在 Power BI 中,如果需要在多个字段上定义关系,则必须通过将字段串联在一起手动构建该复合键作为解决方法。例如,如果需要基于省份...
A common modeling requirement involves adding a date table to support time-based filtering. To support the known time-based filters in your organization, create a table in the source database, and ensure it's loaded with a range of dates encompassing the fact table dates. Also ensure that it...
