Generates an array containing all elements that appear in multiple input arrays, referenced as column names or array literals. |
Array literal reference example:
derive type:single value:ARRAYINTERSECT([["A","B","C"],["A","D","E"]]) |
Output: Generates a single array with a single element:
["A"] |
Column reference example:
derive type:single value:ARRAYINTERSECT([array1,array2]) as:'intersect_Array' |
Output: Generates a new intersect_Array column containing a single array listing all of the elements that appear in both array1 and array2 in order.
derive type:single value:ARRAYINTERSECT(array_ref1,array_ref2) |
