Information functions- These functions look at a table or column provided as an argument to another function and returns whether the value matches the expected type. For example, the ISERROR function returnsTRUEif the value you reference contains an error. ...
Tables in the model when referenced by name work with EVALUATE to output a result table showing the data in the table. For example, EVALUATE ‘Table name’ can be ran as a DAX query. Measures in the model or any DAX formula, which return a scalar value, work with EVALUATE to show the...
to DAX formulas. Errors in formulas or unexpected results, for example, are often caused by using a particular operator that cannot be used with a data type specified in an argument. For example, the formula,= 1 & 2, returns a string result of 12. The formula,= "1" + "2", however...

For example, we might filter just the Car transport.如果再添加一个对Car的筛选,写出计算字段: CountAllNamesCar = CALCULATE ( COUNTROWS ( 'Demo' ), ALL ( 'Demo'[Name] ), 'Demo'[Transport] = "Car" ) In this case, we will reduce the CountAllNamesCar column for a color of Emily to ...
