# CROSSJOIN

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(<table>, <table>[, <table>]…)
```

### 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**.

The table **Colors** contains colors and patterns:

Color | Pattern |
---|---|

Red | Horizontal Stripe |

Green | Vertical Stripe |

Blue | Crosshatch |

The table **Stationery** contains fonts and presentation:

Font | Presentation |
---|---|

serif | embossed |

sans-serif | engraved |

The expression to generate the cross join is presented below:

```
CROSSJOIN( Colors, Stationery)
```

When the above expression is used wherever a table expression is expected, the results of the expression would be as follows:

Color | Pattern | Font | Presentation |
---|---|---|---|

Red | Horizontal Stripe | serif | embossed |

Green | Vertical Stripe | serif | embossed |

Blue | Crosshatch | serif | embossed |

Red | Horizontal Stripe | sans-serif | engraved |

Green | Vertical Stripe | sans-serif | engraved |

Blue | Crosshatch | sans-serif | engraved |
