 ## Return Value
 
-Returns the judgment result: 1: left and right arrays have common elements; 0: left and right arrays do not have common elements; NULL: left or right array is NULL; or any element in left and right array is NULL
+Returns if left and right have any non-null elements in common. Returns null if there are no non-null elements in common but either array contains null.
 
 ## Example
 
-```sql
-SELECT ARRAYS_OVERLAP(['a', 'b', 'c'], [1, 2, 'b']);

 ## 返回值
 
-返回判断结果：1：left 和 right 数组存在公共元素；0：left 和 right 数组不存在公共元素；NULL：left 或者 right 数组为 NULL；或者 left 和 right 数组中，任意元素为 NULL
+如果 left 和 right 具有任何非 null 的共同元素，则返回 true。
+如果没有非 null 的共同元素且任一数组包含 null，则返回 null。
+如果没有非 null 的共同元素，且 left 和 right 都不包含 null，则返回 false。
