Android 没有这样的表：ogrenci:，编译时：插入到

我试图配置一个简单的

SQLiteOpenHelper

，执行时出错

错误是：

表

ogrenci

没有名为

field\uu final

在编写时：

INSERT INTO ogrenci(field__final, field__numarasi, field_ad, field__vize, field__soyad) VALUES(?, ?, ?, ?, ?);

我想不出是什么问题

dbSQLite.java

将

CREATE TABLE

查询更改为：

     String sql = "CREATE TABLE " + TABLO_ADI + " ("
                              + "id INTEGER PRIMARY KEY AUTOINCREMENT, " 
                              + KISI_ADI + " TEXT NOT NULL, "
                              + KISI_SOYADI + " TEXT NOT NULL, " 
                              + KISI_NUMARASI + " TEXT, " 
                              + KISI_VIZE + "TEXT, " 
                              + KISI_FINAL + "TEXT );";

目前您没有在

KISI_NUMARASI

、

KISI_VIZE

和

KISI_FINAL

列之间添加，“，将

创建表

查询更改为：

     String sql = "CREATE TABLE " + TABLO_ADI + " ("
                              + "id INTEGER PRIMARY KEY AUTOINCREMENT, " 
                              + KISI_ADI + " TEXT NOT NULL, "
                              + KISI_SOYADI + " TEXT NOT NULL, " 
                              + KISI_NUMARASI + " TEXT, " 
                              + KISI_VIZE + "TEXT, " 
                              + KISI_FINAL + "TEXT );";

---

目前您没有在

KISI_NUMARASI

，

KISI_即
和
KISI_FINAL
列之间添加，“，请检查您的表是否有名为
field_FINAL
的列。我建议你重新制作桌子。错误表示列
字段\u final
不存在

考虑为列使用更简单的名称，例如，使用类似于
finalNotu
或
final\u notu
的名称，而不是
field\u final
。使用复杂的列名通常是个坏主意

我想这个方法会给你一个想法。。。此方法应属于您的
dbSQLHelper
类

public void reCreate() {
     SQLiteDatabase db = this.getWritableDatabase();
     db.execSQL("DROP TABLE IF EXISTS " + TABLO_ADI);
     String sql = "CREATE TABLE " + TABLO_ADI + " ("
                          + "id INTEGER PRIMARY KEY AUTOINCREMENT," 
                          + KISI_ADI + " TEXT NOT NULL, "
