CROSSJOIN

Applies to: Calculated column Calculated table Measure Visual calculation

Returns a table that contains the Cartesian product of all rows from all tables in the arguments. The columns in the new table are all the columns in all the argument tables.

Syntax

CROSSJOIN(, [, ]…)
Parameters



Term
Definition




table
Any DAX expression that returns a table of data



Return value
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.


This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.


Example
The following example shows the results of applying CROSSJOIN() to two tables: Colors and Stationery.
