NATURALLEFTOUTERJOIN DAX Function (Table manipulation)

Joins the Left table with right table using the Left Outer Join semantics.

Syntax

NATURALLEFTOUTERJOIN ( <LeftTable>, <RightTable> )
Parameter Attributes Description
LeftTable

The Left-side table expression to be used for join.

RightTable

The Right-side table expression to be used for join.

Return values

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

A table which includes only rows from RightTable for which the values in the common columns specified are also present in LeftTable. The table returned will have the common columns from the left table and the other columns from both the tables.

Remarks

There is no sort order guarantee for the results.
Columns being joined on must have the same data type and the same name in both tables.
The columns used in the join condition that correspond to physical columns of the data model must also have the same data lineage; two columns with the same name and different data lineage generate an error.
Two columns with the same data lineage must have also the same full column name, which includes both table name and column name; otherwise, they are not matched for the join.
Strict comparison semantics are used during the join. There is no type coercion; for example, 1 does not equal 1.0.
