The original problem statement did cover security issues, but not in a way that's workable. Here's the relevant portion from the original.
原始的问题陈述的确涉及到安全性问题，但用的方式并不奏效。
If you create a CGTT table using the like clause (create CGTT like a regular table), the statement will be successful, but the CGTT will not inherit the constraints of the original table.
如果您使用like语句创建cgtt表(像普通表一样创建CGTT)，则该语句会执行成功，但CGTT不会继承原始表的约束。
