Question

我在项目中使用 error no such table not found 我使用 2数据库。一个是完美的工作，但另一个显示错误。

这是我的代码

public void onCreate(SQLiteDatabase db) {
    // TODO Auto-generated method stub
    String CREATE_ADDRESS = " CREATE TABLE " + TABLE_ADDRESS  + "(" + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT,"+ KEY_STATE + " TEXT," + KEY_CITY + " TEXT," + KEY_ZIPCODE + " TEXT," + KEY_STREET + " TEXT," + KEY_DOOR + " TEXT,"+ ");";      
    try{
        db.execSQL(CREATE_ADDRESS);
    }catch (SQLException e)
    {
        e.printStackTrace();
    }
}

我尝试使用此代码插入数据

public void addAddress(AddressList address)
{
    SQLiteDatabase db = this.getWritableDatabase();
    ContentValues values = new ContentValues();
    values.put(KEY_STATE, address.getState());
    values.put(KEY_CITY, address.getCity());
    values.put(KEY_ZIPCODE, address.getZipcode());
    values.put(KEY_STREET, address.getStreet());
    values.put(KEY_DOOR, address.getDoor());
    db.insert(TABLE_ADDRESS,null, values);

    db.close();
}

Answer 1

在最后一个TEXT之后的create table语法中有一个额外的,（逗号）。您需要删除它，因为它根据create table的语法无效。

使用此

String CREATE_ADDRESS = " CREATE TABLE " + TABLE_ADDRESS  + "(" + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT,"+ KEY_STATE + " TEXT," + KEY_CITY + " TEXT," + KEY_ZIPCODE + " TEXT," + KEY_STREET + " TEXT," + KEY_DOOR + " TEXT"+ ");";

Answer 2

因为您的 DML 语句不正确，因此未创建第二个表。您必须从导致错误的语句中删除最后一个逗号。在表的最后一列后面不能是逗号，因为它是最后一列。

+ KEY_DOOR + " TEXT"+ ");

Answer 3

您已加入,＆amp;最后一列的;分号。尝试删除上一个,＆amp;最后;可能会修复您的错误。

public void onCreate(SQLiteDatabase db) {
 // TODO Auto-generated method stub
 String CREATE_ADDRESS = " CREATE TABLE " + TABLE_ADDRESS  + "(" + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT,"+ KEY_STATE + " TEXT," + KEY_CITY + " TEXT," + KEY_ZIPCODE + " TEXT," + KEY_STREET + " TEXT," + KEY_DOOR + "  TEXT" + ")";      
 try{
     db.execSQL(CREATE_ADDRESS);
 }catch (SQLException e)
 {
     e.printStackTrace();
 }
}

android错误显示没有这样的表
