나는 테이블을 만들고 데이터를 데이터베이스에 삽입하기 위해 안드로이드 sqlite 데이터베이스에 쿼리를 시도했습니다.오류 삽입 및 테이블을 찾을 수 없습니다.
테이블 함수를 작성 데이터 기능을 삽입
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);
}
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
}
이 코드를 잘하지만 자신이 포함되어 오류가 난
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]

를 실행합니다 사람에 대한 어떤 생각을 가지고 생각 위의 구문에서 잘못 되었습니까? 당신이
전체 코드 DatabaseHandler.java 당신이 적절한 onUpgrade 기능을 사용하지 않고 시간
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);
때때로 코드의이 부분을 편집하는 경우이 문제가 발생
