How do i check if any one element of one array exists in another array. Eg: array1 = [1,2,3,4] array2 = [1,4,5,7] Now i expect the result as true even if any one element matches from array2 in array1.
You can use the overlap - operator:
test=*# select array[1,2,3,4] && array[1,4,5,7]; ?column? ---------- t (1 Zeile)
test=*# select array[1,2,3,4] && array[10,40,50,70]; ?column? ---------- f (1 Zeile)
