我的SQLite代码我找不到这个问题
我试图多次更改任何值并得到相同的错误
public SQLiteHandler(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}

这里从我的主要代码来实现SQLite从注册表中存储
并检查登录屏幕
// Session manager
session = new SessionManager(getApplicationContext());
// SQLite database handler
db = new SQLiteHandler(getApplicationContext());
// Check if user is already logged in or not
if (session.isLoggedIn()) {
// User is already logged in. Take him to main activity
Intent intent = new Intent(Sign_up.this,
ReportActivity.class);
startActivity(intent);
finish();
}
// Progress dialog
progressDialog = new ProgressDialog(this);
progressDialog.setCancelable(false);
mContext = this;
// Register Button Click event
btnSignUp.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
String name = etFname.getText().toString().trim();
String lastname = etLname.getText().toString().trim();
String users_name = etUser.getText().toString().trim();
String password = etPassword.getText().toString().trim();
String id_card = etIdCard.getText().toString().trim();
String mobile = etMobile.getText().toString().trim();
String email = etEmail.getText().toString().trim();
if (!name.isEmpty() && !lastname.isEmpty() && !users_name.isEmpty() && !password.isEmpty() &&!email.isEmpty()
&&!id_card.isEmpty() &&!mobile.isEmpty() ) {
registerUser(name, lastname , users_name, email, id_card , password , mobile);
} else {
Toast.makeText(getApplicationContext(),
"Please enter your details!", Toast.LENGTH_LONG)
.show();
}
}
});
}
private void registerUser(final String name, final String lastname ,final String users_name,
final String email , final String id_card ,final String mobile ,final String password) {
// Tag used to cancel the request
String tag_string_req = "req_register";
progressDialog.setMessage("Registering ...");
showDialog();
StringRequest strReq = new StringRequest(Method.POST,
AppConfig.URL_REGISTER, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Log.d(TAG, "Register Response: " + response.toString());
hideDialog();
try {
JSONObject jObj = new JSONObject(response);
boolean error = jObj.getBoolean("error");
if (!error) {
// User successfully stored in MySQL
// Now store the user in sqlite
String uid = jObj.getString("uid");
JSONObject user = jObj.getJSONObject("user");
String name = user.getString("name");
String lastname = user.getString("lastname");
String users_name = user.getString("users_name");
String created_at = user
.getString("created_at");
String email = user.getString("email");
String id_card = user.getString("id_card");
String mobile = user.getString("mobile");
db.addUser(name, lastname , users_name, uid, created_at , email , id_card ,mobile);
最佳答案
您收到错误“表用户没有名为email的列”，这意味着列创建中存在问题。
因此，请确保执行以下步骤：
更改您的创建查询，例如@Avi Answer
喜欢
@Override
public void onCreate(SQLiteDatabase db) {
String CREATE_LOGIN_TABLE = "CREATE TABLE " + TABLE_USERS + "("
+ KEY_USERS_ID + " INTEGER PRIMARY KEY," + KEY_NAME + " TEXT," + KEY_LASTNAME + " TEXT ,"
+ KEY_ID_CARD + " TEXT ," + KEY_MOBILE + " TEXT ,"
+ KEY_USERS_NAME + " TEXT UNIQUE," + KEY_UID + " TEXT," + KEY_EMAIL + "TEXT "
+ KEY_CREATED_AT + " TEXT" + ")";
db.execSQL(CREATE_LOGIN_TABLE);
Log.d(TAG, "Database tables created");
}
这里您在文本数据类型之前缺少一个逗号和一个空格（在
KEY_EMAIL）
String CREATE_LOGIN_TABLE = "CREATE TABLE " + TABLE_USERS + "("
+ KEY_USERS_ID + " INTEGER PRIMARY KEY," + KEY_NAME + " TEXT," + KEY_LASTNAME + " TEXT ,"
+ KEY_ID_CARD + " TEXT ," + KEY_MOBILE + " TEXT ,"
+ KEY_USERS_NAME + " TEXT UNIQUE," + KEY_UID + " TEXT," + KEY_EMAIL + " TEXT ,"
+ KEY_CREATED_AT + " TEXT" + ")";
更改此查询后，请卸载应用并重新安装。
希望对您有帮助。
谢谢
