android - CREATE 中的错误消息 - 未在 place_info 表中插入记录

Question

我有一个数据库类，我试图在其中创建 3 个表，所有表都创建得很完美，但我无法确定为什么没有记录被插入到第三个表中。它给了我错误。我在这里发布我的代码。请帮我确定是什么问题？

Answer 1

方法 addPlaceInfo(placeInfo pi) 中的下一行，

db.insert(create_table_placeinfo, null, values);//它正在使用创建查询

应该是

db.insert(table_placeInfo, null, values);//使用表名
