问题描述

我想从我的数据库选择的价值，但我得到了错误

i want to select value from my database but i got error

Caused by: java.lang.IllegalStateException: get field slot from row 0 col -1 failed

我不知道哪里是我的code错了..这是我的dbHelper code。

i don't know where is the wrong in my code.. this is my code in dbHelper.

public Cursor pilihEnkripsi( String chiperteks ) {
    Cursor c = dba.rawQuery("SELECT idenkripsi FROM TB_enkripsi where chiperteks = '"+chiperteks+"'", null);
    return c;
}

和我想在其他类中的价值。我用这个code。

and i want to get the value in other class. i use this code.

Cursor cursorEnkripsi = data.pilihEnkripsi(ciper);
    if(cursorEnkripsi.moveToFirst()) {
        idenkripsi = cursorKontak.getString(cursorKontak.getColumnIndex("idenkripsi"));
    }

有人可以帮我吗？我真正需要的解决方案，请帮我..谢谢..关心..

推荐答案

光标cursorKontak应cursorEnkripsi

Cursor cursorKontak should be cursorEnkripsi

Cursor cursorEnkripsi = data.pilihEnkripsi(ciper);
    if(cursorEnkripsi.moveToFirst()) {
        //idenkripsi = cursorKontak.getString(cursorKontak.getColumnIndex("idenkripsi"));
          idenkripsi = cursorEnkripsi.getString(cursorEnkripsi.getColumnIndex("idenkripsi"));
    }
