Parameters

NameTypeRequiredDescription
set1…setNdynamic✔️Arrays used to create an intersect set. A minimum of 2 arrays are required. See pack_array.

Returns

Returns a dynamic array of the set of all distinct values that are in all arrays.

Example

range x from 1 to 3 step 1
| extend y = x * 2
| extend z = y * 2
| extend w = z * 2
| extend a1 = pack_array(x,y,x,z), a2 = pack_array(x, y), a3 = pack_array(w,x)
| project set_intersect(a1, a2, a3)

Output

Column1
[1]
