Table constructor

Returns a table of one or more columns.

Syntax

{ <scalarExpr1>, <scalarExpr2>, … } 
{ ( <scalarExpr1>, <scalarExpr2>, … ), ( <scalarExpr1>, <scalarExpr2>, … ), … }

Parameters

Term	Definition
scalarExprN	Any DAX expression that returns a scalar value.

Return value

A table of one or more columns. When there is only one column, the name of the column is Value. When there are N columns where N > 1, the names of the columns from left to right are Value1, Value2, …, ValueN.

Remarks

• The first syntax returns a table of a single column. The second syntax returns a table of one or more columns.

• The number of scalar expressions must be the same for all rows.

• When the data types of the values for a column are different in different rows, all values are converted to a common data type.

Example 1

The following DAX queries:

EVALUATE { 1, 2, 3 }

and

EVALUATE { (1), (2), (3) }

Return the following table of a single column:

[Value]
1
2
3

Example 2

The following DAX query:

EVALUATE
    {
        (1.5, DATE(2017, 1, 1), CURRENCY(199.99), "A"),
        (2.5, DATE(2017, 1, 2), CURRENCY(249.99), "B"),
        (3.5, DATE(2017, 1, 3), CURRENCY(299.99), "C")
    }

Returns,

[Value1]	[Value2]	[Value3]	[Value4]
1.5	1/1/2017	199.99	A
2.5	1/2/2017	249.99	B
3.5	1/3/2017	299.99	C

Example 3

The following DAX query:

EVALUATE { 1, DATE(2017, 1, 1), TRUE, "A" }

Returns the following table of a single column of String data type:

[Value]
1
1/1/2017
TRUE
A
