fixed [customer ID] : countd(order) 在视图中,我们仅使用两个维度——购买频次和顾客的计数,也就是两个都是数值。用官方的方式说,这是用一个数值去区分另一个数值(breaking out a measure by another measure ),LOD fixed可以轻松地把一个度量转化为维度,这是include和exclude不能做的。
fixed 可以理解为绝对表达式,它返回的数组仅和语法指定的维度有关,与视图无关,因此特别适合做计算字段并参与到复杂的运算中;而 Include 和 Exclude 可以理解为相对表达式,它们一方面受限于视图中已有的维度,另一方面受限于语法中指定的维度。 特别重要的是,Fixed LOD 表达式先于维度筛选器,这就意味着如果要时计算结果...
You'll learn the difference between each calculation and how they are computed. There are three main types of calculations you can use to create calculated fields in Tableau: Basic expressions Level of Detail (LOD) expressions Table calculations Basic expressions Basic expressions allow you to ...
It’s also important to bear in mind the difference between the Tableau data source (Tableau’s access to your data and all the customizations that may be involved) and the source data itself (such as a database or Excel spreadsheet). Planning a data source in the sense of designing a ...

The difference is that the failed condition will not return the NULL value but instead will return the specified return value. If the conditional expression is satisfied (TRUE), the statement after the THEN keyword will be returned. When the conditional expression is not satisfied (FALSE), the ...
A parameter is a global placeholder value that can replace a constant value in a Prep flow. Parameters can be specified at run time or schedule time to easily transition a flow to be used on different inputs and outputs with the same schema, as well as quickly edit values used throughout...
A key distinction between INCLUDE/EXCLUDE and FIXED is where each falls in the filtering hierarchy as shown below. FIXED LOD Expressions are computed before dimension filters and after context filters. This can enable many use cases FIXED LOD expression filters are appli...
