最近我一直在尝试从sqlite迁移到MySQL5.6（5.7在gis字段方面有问题）。我意识到我的3d点都没有导入mysql数据库，所以我进去手动尝试用django dumpdata输出更新行，但显然它不接受3d点，也没有给出任何警告或错误。
我应该切换到另一个数据库系统吗？我做错什么了吗？

mysql> UPDATE entrance SET location=GeomFromText("POINT Z (32.077624 36.58562 123)") WHERE id=1;
Query OK, 0 rows affected (0.03 sec)
Rows matched: 1  Changed: 0  Warnings: 0

mysql> UPDATE entrance SET location=GeomFromText("POINT(32.077624 36.58562)") WHERE id=1;
Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0

mysql> SHOW COLUMNS FROM entrance;
