编辑和添加数据库时遇到问题

我试图编辑和搜索问题，但是找不到解决方法

   public boolean insert_dealer(get_set_db dealer){

        ContentValues Values = new ContentValues();
       Values.put(My_data.dealer_CLN_NMEA  , dealer.getName());
       Values.put(My_data.dealer_CLN_description , dealer.getDescribe());
       Values.put(My_data.dealer_CLN_image , dealer.getImage());
       Values.put(My_data.dealer_CLN_WHOLESALE , dealer.getWholesale());
       Values.put(My_data.dealer_CLN_INDIVIDUAL , dealer.getAn_individual());

       long result = database.insert(My_data.dealer_TB_NAME,null,Values);
       return result != -1;
   }

Answer 1

在这里Dealer.getAn_CLN_INDIVIDUAL（）返回“个人”，此处您不能使用空格保留属性名称。只需将其更改为an_individual，希望它可以工作。

My_data.dealer_CLN_INDIVIDUAL , dealer.getAn_individual()

Answer 2

代表列名的常量My_data.dealer_CLN_INDIVIDUAL已定义为：

String dealer_CLN_INDIVIDUAL = "An individual";

列名不能包含空格。
您可以将其括在方括号中以解决问题：

String dealer_CLN_INDIVIDUAL = "[An individual]";
