CROSSJOIN DAX Function (Table manipulation)

Returns a table that is a crossjoin of the specified tables.

Syntax

CROSSJOIN ( <Table> [, <Table> [, … ] ] )
Parameter Attributes Description
Table Repeatable

A table that will participate in the crossjoin.

Return values

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

A table that contains the Cartesian product of all rows from all tables in the arguments.

Remarks

Column names from table arguments must all be different in all tables or an error is returned.

The total number of rows returned by CROSSJOIN() is equal to the product of the number of rows from all tables in the arguments; also, the total number of columns in the result table is the sum of the number of columns in all tables. For example, if TableA has rA rows and cA columns, and TableB has rB rows and cB columns, and TableC has rC rows and cC column; then, the resulting table has rA × rB × rC rows and cA + cB + cC columns.
