SQLiteDatabase錯誤插入

Question

的主要問題，

1. 是否可以依靠的onCreate補充更新到數據庫表，而不使用的onUpdate的？

2. AUTOINCREMENT是否適用於STRING列。在這裏無能爲力。

所以我收到一個錯誤，指出我的插入有問題。從生成的結果證明，Cursor.getCount（）不斷/只輸出1的舊記錄。 我似乎無法插入以創建第二行。

// All Static variables 
// Database Version 
private static final int DATABASE_VERSION = 1; 

// Database Name 
private static final String DATABASE_NAME = "AccountDB"; 

// Account table name 
private final String TABLE_ACCOUNTS = "AccountTable"; 

    public void onCreate(SQLiteDatabase db) { 

    //boolean dbExist = checkDataBase(); 

    String CREATE_CONTACTS_TABLE = " CREATE TABLE " + TABLE_ACCOUNTS + "(" 
      + id + " TEXT PRIMARY KEY AUTOINCREMENT ," + fullname + " TEXT," 
      + username + " TEXT," + password + " TEXT,"+ email + " TEXT," + contact_no + " TEXT,"+ activated + " TEXT," + banned + " TEXT," + ban_reason + " TEXT,"+ new_password_key + " TEXT," + new_password_requested + " TEXT," 
      + new_email + " TEXT," + new_email_key + " TEXT," + last_ip + " TEXT," + last_login + " TEXT," + created + " TEXT,"+ modified +" TEXT, " + encrypt_key + " TEXT,"+ login_key + " TEXT" + ");"; 
    db.execSQL(CREATE_CONTACTS_TABLE); 

} 

    SQLiteDatabase db = this.getWritableDatabase(); 

    ContentValues values = new ContentValues(); 
    values.put(id, acc.getID()); 
    values.put(fullname, acc.getFullname()); 
    values.put(username, acc.getUsername()); 
    values.put(password, acc.getPassword()); 
    values.put(email, acc.getEmail()); 
    values.put(contact_no, acc.getContactNo()); 
    values.put(activated, acc.getActivated()); 
    values.put(banned, acc.getBanned()); 
    values.put(ban_reason, acc.getBanReason()); 
    values.put(new_password_key, acc.getNewPasswordKey()); 
    values.put(new_password_requested, acc.getNewPasswordRequested()); 
    values.put(new_email, acc.getNewEmail()); 
    values.put(new_email_key, acc.getNewEmailKey()); 
    values.put(last_ip, acc.getLastIP()); 
    values.put(last_login, acc.getLastLogin()); 
    values.put(created, acc.getCreated()); 
    values.put(modified, acc.getModified()); 
    values.put(encrypt_key, acc.getEncryptKey()); 
    values.put(login_key, acc.getLoginKey()); 
    System.out.println("hohoho "+acc.getLoginKey()); 
    Log.v("response",acc.getLoginKey()); 
    Log.v("DATABASEHandler","Table populated"); 
    // Inserting Row 
    //System.out.println("hereee"+account.getLoginKey()); 
    db.insert(TABLE_ACCOUNTS, null, values); 


    Cursor mCursor =db.query(TABLE_ACCOUNTS, new String[] {id, 
         fullname, username,password,email,contact_no,activated, 
         banned,ban_reason,new_password_key,new_password_requested, 
         new_email,new_email_key,last_ip,last_login,created,modified, 
         encrypt_key,login_key}, null,null, null, null, null); 


    int count = mCursor.getCount(); 
    Log.d("Database stuff", "Count is "+count); 
    if(mCursor != null) 
     mCursor.moveToNext(); 

輸出：

Answer 1

您試圖在其中有NOT NULL約束字段中插入空值。檢查一下。我認爲last_ip是空的。

編輯：

它違反了一些其他約束條件。我認爲它的問題是由於TEXT上的自動增量。試試這個：

String CREATE_CONTACTS_TABLE = " CREATE TABLE " + TABLE_ACCOUNTS + "(" 
      + id + " NUMBER PRIMARY KEY AUTOINCREMENT ," + fullname + " TEXT," 
      + username + " TEXT," + password + " TEXT,"+ email + " TEXT," + contact_no + " TEXT,"+ activated + " TEXT," + banned + " TEXT," + ban_reason + " TEXT,"+ new_password_key + " TEXT," + new_password_requested + " TEXT," 
      + new_email + " TEXT," + new_email_key + " TEXT," + last_ip + " TEXT," + last_login + " TEXT," + created + " TEXT,"+ modified +" TEXT, " + encrypt_key + " TEXT,"+ login_key + " TEXT" + ");";
