我试图做一个查询到android sqlite数据库创建表和插入数据到数据库。错误插入和表找不到
创建表函数
public void onCreate(SQLiteDatabase db) {
String CREATE_LOGIN_TABLE = "CREATE TABLE " + TABLE_LOGIN + "("
+ KEY_ID + " INTEGER PRIMARY KEY,"
+ KEY_ID_USER + " TEXT,"
+ KEY_NAMA + " TEXT,"
+ KEY_EMAIL + " TEXT UNIQUE,"
+ KEY_REGID + " TEXT,"
+ KEY_DIBUAT_AT + " TEXT" + ")";
db.execSQL(CREATE_LOGIN_TABLE);
}
插入数据功能
public void addUser(String id_user, String name, String email, String regid, String created_at) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(KEY_NAMA, name); // Name
values.put(KEY_ID_USER, id_user);
values.put(KEY_EMAIL, email); // Email
values.put(KEY_REGID, regid); // Email
values.put(KEY_DIBUAT_AT, created_at); // Created At
// Inserting Row
db.insert(TABLE_LOGIN, null, values);
db.close(); // Closing database connection
}
我觉得这个代码是正确的，但他的包含错误将我跑
05-05 11:19:15.549: E/SQLiteDatabase(29294): Error inserting regid=XX1 id_user=12 nama=Edwin Andrianto dibuat_at=2013-05-01 15:11:41 [email protected]
05-05 11:19:15.549: E/SQLiteDatabase(29294): android.database.sqlite.SQLiteException: table login has no column named id_user: , while compiling: INSERT INTO login(regid,id_user,nama,dibuat_at,email) VALUES (?,?,?,?,?)
有任何人任何想法是什么在上面的语法中是错误的？谢谢

**表登录已没有列命名id_user **它说一切 – Pragnani 2013-05-05 05:37:47
在哪里位在其中设置KEY_ID_USER的价值？在那里寻找你的问题。 – MarsAtomic 2013-05-05 05:38:08
是key_id_user和id_user是一样的吗？ – Akhil 2013-05-05 05:40:15
