DATATABLE DAX Function (Table manipulation)

Returns a table with data defined inline.


DATATABLE ( <name>, <type> [, <name>, <type> [, … ] ], <data> )
Parameter Attributes Description
name Repeatable

A constant string that defines the name of the column. A dynamic expression is not allowed.

type Repeatable



The data for the table.

Where {values in row1} is a comma delimited set of constant expressions, namely a combination of constants, combined with a handful of basic functions including DATE, TIME, and BLANK, as well as a plus operator between DATE and TIME and a unary minus operator so that negative values can be expressed.

The following are all valid values: 3, -5, BLANK(), “2009-04-15 02:45:21”. Values may not refer to anything outside the immediate expression, and cannot refer to columns, tables, relationships, or anything else.

A missing value will be treated identically to BLANK(). For example, the following are the same: {1,2,BLANK(),4} {1,2,,4}

Return values

Table An entire table or a table with one or more columns.

A table declaring an inline set of values.


Unlike DATATABLE, the table constructor allows any scalar expressions as input values.

The syntax used by DATATABLE is different from that used by the table constructor.

The data type name specified in DAX differs from the data types available in the user interface of products that use DAX, such as Power BI, Excel, and Visual Studio. Specifically, CURRENCY corresponds to a Fixed Decimal Number in Power BI, whereas DOUBLE corresponds to the Decimal Number in Power BI and Decimal in the DAX Data types list.

--  DATATABLE is useful to build constant tables in code.
--  It requires the list of arguments and the list of rows
--  to build the table.
    "Name", STRING,
    "Ordinal", INTEGER,
        { "Small",  1 },
        { "Medium", 2 },
        { "Large",  3 }
ORDER BY [Ordinal]
Name Ordinal
Small 1
Medium 2
Large 3

Values in the definition of the table cannot be expressions; they need to be constant. The following syntax is not valid and generates an error.

    "Aggregation", STRING,
    "Value", CURRENCY,
        { "Min", MIN ( Sales[Net Price] ) },
        { "Max", MAX ( Sales[Net Price] ) }

Tables with calculated expressions can be computed using the ROW function, or the table constructor {}, instead of using DATATABLE.
The table constructor requires renaming the columns.

    UNION (
        ROW ( "Aggregation", "Min", "Value", MIN ( Sales[Net Price] ) ),
        ROW ( "Aggregation", "Max", "Value", MAX ( Sales[Net Price] ) )

            ( "Min", MIN ( Sales[Net Price] ) ),
            ( "Max", MAX ( Sales[Net Price] ) )
        "Aggregation", [Value1],
        "Value", [Value2] 
Aggregation Value
Min 0.76
Max 3,199.99
Aggregation Value
Min 0.76
Max 3,199.99
