您不能在一个简单的表中.我了解您的意思，例如，您想存储以下内容:

You can´t in a simple table. I understand your point, you want to store, for example, something like this:

citizen = {
  "name":"",
  "id":"",
  "childrens":{
     children1:{
       "name":"",
       "id":"",
     }
     children2:{
       "name":"",
       "id":"",
     }
  }
}

这是因为sqflite是使用设备sqlite的工具，并且该数据库在apache软件下工作.这意味着Sqflite会存储数据，而sql DB会存储数据，而您不能在sql表中存储对象.

This is because sqflite is a tool to use the device sqlite and this DB works under apache software. That means, Sqflite stores data as well sql DB stores data and you can't store objects in a sql table.

您应根据需要为每个复杂数据创建其他表.像这样的东西(作为伪代码):

You should create other table for each complex data as you need. Something like this (as pseudocode):

'CREATE TABLE Citizen ('
          ' id INTEGER PRIMARY KEY,'
          ' name TEXT,'
          ' children1Id INTEGER,'
          ' children2Id INTEGER,'
          '); '
'CREATE TABLE Children ('
          ' id INTEGER PRIMARY KEY,'
          ' name TEXT'
          ')'

我希望这会对您有所帮助.

I hope this will help you.
