Hi, I found that even if I don't use try, when the expression may have an error, it will still return null

mysql> select cast("a" as integer);
+------------------+
| CAST('a' AS INT) |
+------------------+
|             NULL |
+------------------+
1 row in set (0.02 sec)

mysql> select current_version();
+-------------------+
| current_version() |
+-------------------+
| main-defc9c3      |
+-------------------+
1 row in set (0.02 sec)

do you have any examples I can use for testing?
