这是最期待的功能,DAX终于要支持自定义函数了,官方名称是用户定义函数(User-Defined Functions,简称UDF),允许在DAX中定义可重用函数,解决代码重复问题,提升复杂模型的可维护性。 UDF存在于语义模型中,支持通用函数库和模型特定逻辑共享,这个功能推出后,将彻底改变DAX公式的编写方式。 以上这些功能功能目前尚未上线,预计...

DAX functions are changed to UPPERCASE, and extra lines are added. Formatting your DAX query is considered a best practice and improves the DAX query readability. The formatting also indents in such a way that you can collapse and expand sections of the query. Comment and Uncomment Select the...
Find out more about DAX functions or topics while you are in DAX query view with Copilot.This explanation will try and give you an example using your semantic model: staying in context of where you are working. No longer do you have to go to a search engine to find the answer using s...
Today, we are happy to announce support for the DAX UserCulture function in Power BI Premium. Combined with the field parameters feature, customers can create reports that natively translate table data to the locale defined by the viewer’s preferences in the Power BI service. Although...
Aggregation functions calculate a (scalar) value such as count, sum, average, minimum, or maximum for all rows in a column or table as defined by the expression. To learn more, seeAggregation functions. Date and time functions The date and time functions in DAX are similar to date and tim...
DAX 根据运算符的需要执行数据类型的自动转换。即使这种行为是自动发生的,DAX 仍然提供了一组函数用来执行显示的类型转换。 CURRENCY CURRENCY ( <Value> ) 将表达式结果转换为货币类型 CURRENCY 函数四舍五入第 5 位有效小数的值,返回第 4 位小数;如果第 5 位有效小数等于或大于 5,则进行舍入。例如,如果 value...
This pattern describes how to compute week-related calculations, such as year-to-date, same period last year, and percentage growth using a week granularity. This pattern does not rely on DAX built-in time intelligence functions. All the measures refer to the fiscal …Read more ...
Row context can be thought of as "the current row.” If you have created a calculated column, the row context consists of the values in each individual row and values in columns that are related to the current row. There are also some functions (EARLIERandEARLIEST) that get a value from...
