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.

Basic Usage

Array literal reference example:

derive type:single value:ARRAYCONCAT([["A","B","C"],["C","D","E"]])

Output: Generates a new column with the following array:


Column reference example:

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.

Syntax and Arguments

derive type:single value:ARRAYCONCAT(array_ref1,array_ref2)

ArgumentRequired?Data TypeDescription
array_ref1Ystring or arrayName of first column or first array literal to apply to the function
array_ref2Ystring or arrayName of second column or second array literal to apply to the function

For more information on syntax standards, see Language Documentation Syntax Notes.

array_ref1, array_ref2

Array literal or name of the array column whose elements you want to concatenate together. You can concatenate together two or more arrays.

Usage Notes:

Required?Data TypeExample Value
YesArray literal or column referencemyArray1, myArray2

Example - Simple concat example

This simple example illustrates how the following functions operate on nested data.


Code formatting has been applied to improve legibility.



You can apply the following transforms in the following order. Note that the column names must be different from the transform name, which is a reserved word.

derive type:single value:ARRAYCONCAT([Letters,Numerals]) as:'concat2'

derive type:single value:ARRAYINTERSECT([Letters,Numerals]) as:'intersection2'

derive type:single value:ARRAYCROSS([Letters,Numerals]) as:'cross2'

derive type:single value:ARRAYUNIQUE([Letters,Numerals]) as:'unique2'


Column set 1:




["1","2","3"]["A","B","C","1","2","3"][ ] 
Item3["D","E","F"]["4","5","6"]["D","E","F","4","5","6"][ ]

Column set 2:

Item3[["D","4"],["D","5"],["D","6"],["E","4"],["E","5"],["E","6"], ["F","4"],["F","5"],["F","6"]]["D","E","F","4","5","6"]
