EXAMPLE  Nested Functions
This example illustrates how to use the nested functions.
Functions:
Item  Description 

ARRAYCONCAT Function  Combines the elements of one array with another, listing all elements of the first array before listing all elements of the second array. 
ARRAYINTERSECT Function  Generates an array containing all elements that appear in multiple input arrays, referenced as column names or array literals. 
ARRAYCROSS Function  Generates a nested array containing the crossproduct of all elements in two or more arrays. 
ARRAYUNIQUE Function  Generates an array of all unique elements among one or more arrays. 
Source:
Code formatting has been applied to improve legibility.
Item  ArrayA  ArrayB 

Item1  ["A","B","C"]  ["1","2","3"] 
Item2  ["A","B"]  ["A","B","C"] 
Item3  ["D","E","F"]  ["4","5","6"] 
Transformation:
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.
Transformation Name 


Parameter: Formula type  Single row formula 
Parameter: Formula  ARRAYCONCAT([Letters,Numerals]) 
Parameter: New column name  'concat2' 
Transformation Name 


Parameter: Formula type  Single row formula 
Parameter: Formula  ARRAYINTERSECT([Letters,Numerals]) 
Parameter: New column name  'intersection2' 
Transformation Name 


Parameter: Formula type  Single row formula 
Parameter: Formula  ARRAYCROSS([Letters,Numerals]) 
Parameter: New column name  'cross2' 
Transformation Name 


Parameter: Formula type  Single row formula 
Parameter: Formula  ARRAYUNIQUE([Letters,Numerals]) 
Parameter: New column name  'unique2' 
Results:
For display purposes, the results table has been broken down into three separate sets of columns.
Column set 1:
Item  ArrayA  ArrayB  concat2  intersection2 

Item1 
 ["1","2","3"]  ["A","B","C","1","2","3"] 

Item2  ["A","B"]  ["A","B","C"]  ["A","B","A","B","C"]  ["A","B"] 
Item3  ["D","E","F"]  ["4","5","6"]  ["D","E","F","4","5","6"]  [ ] 
Column set 2:
Item  cross2 

Item1  [["A","1"],["A","2"],["A","3"],["B","1"],["B","2"],["B","3"],["C","1"],["C","2"],["C","3"]] 
Item2  [["A","A"],["A","B"],["A","C"],["B","A"],["B","B"],["B","C"]] 
Item3  [["D","4"],["D","5"],["D","6"],["E","4"],["E","5"],["E","6"], ["F","4"],["F","5"],["F","6"]] 
Column set 3:
Item  unique2 

Item1  ["A","B","C","1","2","3"] 
Item2  ["A","B","C"] 
Item3  ["D","E","F","4","5","6"]
