我在我的sqlite数据库中插入数据时遇到问题。我通过互联网获取JSON数据，而不是试图将数据放入sqlite数据库，但它给我一个constraint failes error。我知道这意味着我已经插入了相同的数据，或者至少具有相同的ID，但是当我从模拟器查看我的数据库时，该表是空的并且没有数据。这是我使用的代码：
public boolean executeInsert() {
UserDatabaseHelper userDbHelper = new UserDatabaseHelper(context, null, 1);
userDbHelper.initialize(context);
ContentValues values = new ContentValues();
values.put("objectId", objectId);
Log.i("objectd Id ","object ID : "+objectId);
values.put("objectOid", objectOid);
Log.i("objectd Oid ","object OID : "+objectOid);

String sql = "SELECT * FROM collections WHERE objectId = " + objectId;
Cursor mCursor = userDbHelper.executeSQLQuery(sql);
if(mCursor.getCount()==0){
userDbHelper.executeQuery("collections", values);
mCursor.close();
} else{
for(mCursor.moveToFirst(); mCursor.moveToNext(); mCursor.isAfterLast()) {
int mObjectId = mCursor.getInt(mCursor.getColumnIndex("objectId"));
if (objectId != mObjectId) {
userDbHelper.executeQuery("collections", values);
}
}
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
Log.w("Error","FUCKKKKKKKKKKKKKK ERROR : "+e);
} catch (JSONException e) {
e.printStackTrace();
Log.w("Error","FUCKKKKKKKKKKKKKK ERROR : "+e);
} finally {
userDbHelper.close();
}
return true;
}
这是我得到的例外：

UserDbHelper类是我的数据库助手类。我用它来将数据放入sqlite.I与其他表没有任何问题。我可以使用与此类似的代码将数据放在它们上，但集合表只是不想工作..
那么任何建议/帮助或其他可以帮助我解决问题的东西？ 谢谢！

我们知道Sqlite是数据库的较轻版本，可在多个移动平台上使用。由于它不是一个完整的RDBMS，它支持一些数据类型而不是所有数据类型。
请检查您是否正确插入数据。
答案 1 :(得分：0)
有一些事情可以引发此异常。我认为您首先需要检查是否要插入所有NOT NULL行，以便确保插入所有绑定行。
