Question

我试图向数据库插入一些值，它显示没有找到这样的表的异常。

我在OpenHelper类中用于创建数据库的代码是

//Call Details Table
static final String Tablenamecall = "call_details";
static final String key_idcall = "key_idcall";
static final String datecall = "datecall";
static final String timecall = "timecall";
static final String toaddcall = "toaddcall";

查询表创建

public void onCreate(SQLiteDatabase db) 
{

    db.execSQL("CREATE TABLE "+Tablenamecall+"("+key_idcall+" INTEGER PRIMARY KEY, "+datecall+" TEXT, "+timecall+" TEXT, "+toaddcall+" TEXT)");

}

插入表格的代码是

    //Call Details Insertion Here

public void calldetails_insertion(String date11 ,String time11 ,String to11) 
{
    SQLiteDatabase db=this.getWritableDatabase();
    ContentValues cv=new ContentValues();

     cv.put(datecall, date11);
     cv.put(timecall, time11);
     cv.put(toaddcall, to11);


     db.insert(Tablenamecall, datecall, cv);


     db.close();
     Log.v("DB", "Inset_User OK"); 
}

我在活动中使用的代码是

        OpenHelper db_obj =  new OpenHelper(context);
            db_obj.calldetails_insertion(dateString, timeString,phoneNumberString);

log cat输出

Answer 1

试试如下：

将创建表查询主键更改为自动增量并插入数据，如下所示：

db.execSQL("CREATE TABLE "+Tablenamecall+" ("+key_idcall+" INTEGER PRIMARY KEY AUTOINCREMENT, "+datecall+" TEXT, "+timecall+" TEXT, "+toaddcall+" TEXT)"

  public void calldetails_insertion(String date11 ,String time11 ,String to11) 
 {
     SQLiteDatabase db=this.getWritableDatabase();
     ContentValues cv=new ContentValues();
      cv.put(datecall, date11);
      cv.put(timecall, time11);
      cv.put(toaddcall, to11);
      db.insert(Tablenamecall, null, cv); <---- check this line and change it.
      db.close();
      Log.v("DB", "Inset_User OK"); 
  }
