Generates an array containing all elements that appear in multiple input arrays, referenced as column names or array literals. |
Array literal reference example:
| D lang syntax |
|---|
| RawWrangle | true |
|---|
| Type | ref |
|---|
| showNote | true |
|---|
| WrangleText | derive type:single value:arrayintersect([["A","B","C"],["A","D","E"]] ) |
|---|
|
arrayintersect([["A","B","C"],["A","D","E"]] ) |
Output: Returns a single array with a single element:
Column reference example:
| D lang syntax |
|---|
| RawWrangle | true |
|---|
| Type | ref |
|---|
| showNote | true |
|---|
| WrangleText | derive type:single value:arrayintersect([array1,array2]) as:'intersect_Array' |
|---|
|
arrayintersect([array1,array2]) |
Output: Returns a single array listing all of the elements that appear in both array1 and array2 in order.
