| Excerpt |
|---|
Generates a nested array containing the cross-product of all elements in two or more arrays. |
- Input arrays can be referenced as column names or array literals.
- If Array1 has M elements and Array2 has N elements, the generated array has M X N elements.
| Info |
|---|
NOTE: Be careful applying this function across columns of large arrays. A limit is automatically applied on large arrays to prevent overloading the browser. Avoid apply the ARRAYCROSS transform to very wide columns. |
Array literal reference example:
| D code |
|---|
derive type:single value:ARRAYCROSS[["A","B"],["1","2","3"]]) |
Output: Generates a single array:
| Code Block |
|---|
[["A","1"],["A","2"],["A","3"],["B","1"],["B","2"],["B","3"]] |
Column reference example:
| D code |
|---|
derive type:single value:ARRAYCROSS(array1,array2,array3) as:'cross_Array' |
Output: Generates a new cross_Array column containing a single array listing all combinations of elements between array1, array2, and array3.
| D code |
|---|
derive type:single value:ARRAYCROSS(array_ref1,array_ref2) |
| Argument | Required? | Data Type | Description |
