+### description
+
+#### syntax
+`explode_numbers(INT x)`
+
+Adding the `_outer` suffix after the function name of the table function changes the function behavior from `non-outer` to `outer`, and adds a row of `Null` data when the table function generates 0 rows of data.
+
+### example
+
+```
+mysql> select e1 from (select 1 k1) as t lateral view explode_numbers(0) tmp1 as e1;
+Empty set
+
+mysql> select e1 from (select 1 k1) as t lateral view explode_numbers_outer(0) tmp1 as e1;
++------+
+| e1   |
++------+
+| NULL |
++------+
+```
