|---|
Combines the elements of one array with another, listing all elements of the first array before listing all elements of the second array. |
- Arrays are referenced by column name or as array literals.
- This function applies two or more columns of Array type only. To concatenate string values, see Merge Transform.
- Duplicate values are not removed from the generated array.
Array literal reference example:
| D code |
|---|
derive type:single value:ARRAYCONCAT([["A","B","C"],["C","D","E"]]) |
Output: Generates a new column with the following array:
| Code Block |

["A","B","C","C","D","E"] |
Column reference example:
| D code |
|---|
derive type:single value:ARRAYCONCAT([array1,array2]) as:'concat_Arrays' |
Output: Generates a new concat_Arrays column containing a single array listing all of the elements in array1 followed by all elements from array2 in order.
| D code |
|---|
derive type:single value:ARRAYCONCAT(array_ref1,array_ref2) |
