ADDCOLUMNS DAX Function (Table manipulation)
Returns a table with new columns specified by the DAX expressions.
Syntax
| Parameter | Attributes | Description |
|---|---|---|
|
Table Iterator |
The table to which new columns are added. |
|
| Name | Repeatable |
The name of the new column to be added. |
|
Expression Row Context |
Repeatable |
The expression for the new column to be added. |
Return values
A table with all its original columns and the added ones.
Remarks
ADDCOLUMNS does not preserve the data lineage of the added columns for a following context transition, even if a column expression is a simple column reference. However, the data lineage of the column added is effective for NATURALLEFTOUTERJOIN and NATURALINNERJOIN.

-- ADDCOLUMNS is an iterator that returns its first argument
-- after adding the column specified.
-- New columns are computed in the row context of ADDCOLUMNS,
-- you need to invoke context transition to generate a filter
-- context, if needed.
