Returns a list of key column values from rows in the specified table or slice in which the specified Ref
-type column refers to this row (the row from which the REF_ROWS()
expression is evaluated).
Answers the question: which rows in from-dataset
refer to this row from ref-column
?
Sample usage
REF_ROWS("Order Details", "Order ID")
gives a list of rows from the Order Details table whose Order ID column value matches this row's key column value, where "this row" is the row from which the REF_ROWS() expression is evaluated.
REF_ROWS("Order Details", "Order ID")
is functionally equivalent to each of the following:
FILTER("Order Details", ([_THISROW] = [Order ID]))
SELECT(Order Details[Order Details ID], ([_THISROW] = [Order ID]))
.
Syntax
REF_ROWS("from-dataset", "ref-column")
from-dataset
- Name of the table or slice (the "data set") in which related rows are to be found.ref-column
- Name of a column in the data set named byfrom-dataset
that containsRef
-type values.
Note: Both arguments must be raw text values (quoted or unquoted) that identify an existing table or slice (from-dataset
) and column (ref-column
); they may not be expressions.
Magical Behavior
If a column's App formula consists exclusively of a simple REF_ROWS()
expression, a row added from the resulting list's inline view will automatically be populated with a reference back to the row of the REF_ROWS()
expression, creating a child-parent relationship. The parent reference will be placed in the column named by the ref-column
argument of the REF_ROWS()
expression.
