没找到这个参数呢

mysql> select version();
+--------------------+
| version()          |
+--------------------+
| 8.0.11-TiDB-v7.5.5 |
+--------------------+
1 row in set (0.00 sec)

mysql> show global variables like '%temp%';
+------------------------+-------+
| Variable_name          | Value |
+------------------------+-------+
| avoid_temporal_upgrade | OFF   |
| show_old_temporals     | OFF   |
+------------------------+-------+
2 rows in set (0.01 sec)
