如何解决通过命令行运行准备好的语句
我正在PHP + MariaDB上运行Pimcore。并且除了重建过程外，我还需要通过命令行清空Pimcore数据对象。
但是，当我使用MysqL < MyScript.sql运行它时，出现以下错误：
ERROR 1064 (42000) at line 12: You have an error in your sql Syntax; check the manual that corresponds to your MariaDB server version for the right Syntax to use near 'NULL' at line 1。
为了使事情更加混乱，该脚本在交互式外壳中可以完美运行。通过PREPARE语句验证SELECT并完美运行。
有人知道发生了什么吗？脚本中没有NULL，并且SELECT生成的所有输出中都没有NULL。
很想听听您的想法/想法！
干杯！

根据要求，这是TABLES（第二条语句）的输出
