These values can be summed up. Syntax BLANK() For details on the behavior of an individual function or operator, see the list of types of functions on the Data Analysis Expressions (DAX) page. DAX does not support use of the variant data type. The DAX language always uses tables and columns as inputs to functions, never an array or arbitrary set of values. It means that it is a type of formulae or expressions that are used for the analysis and calculations of data.

Operators, constants, and values provided as part of an expression. Therefore, when you load or import data into a data model, it's expected the data in each column is generally of a consistent data type. Not only is there no way to check query syntax using this method, but you can't even drag things in from the explorer window on the left (if you do, the query editor uses MDX syntax, not DAX).

Some functions also return tables, which are stored in memory and can be used as arguments to other functions. In general, however, the following rules apply to all formulas and expressions: DAX formulas and expressions cannot modify or insert individual values in tables.
