How to resolve SQLiteException error when insert data in database

So basically I am stuck as to why I cannot add any data. I have basically followed along with a youtube tutorial from scratch but for some reason, one particular error is quite persistent. (It does not allow me to add data, as such I cannot make any use of it.)
Below is the code I have been running and any help would be appreciated :) of course, point me in the right direction if this has been asked previously...I did try searching first. I can see it says theres no column named name in user_table, but what i dont understand is there was no such step in the youtube video and it worked fine?
Forgot to add error
E/SQLiteLog: (1) table Users_Table has no column named NAME
E/SQLiteDatabase: Error inserting NAME=Kono
android.database.sqlite.SQLiteException: table Users_Table has no column named NAME (code 1 SQLITE_ERROR): , while compiling: INSERT INTO Users_Table(NAME) VALUES (?)

How can I display a column from my database into a text view in Android Studio?

Hey guys I have been trying this for 2 days now and I cant seem to get it to work. I have tried every tutorial! I am new to android studio and have been trying to make a simple app where I can register and login. I was able to create the database and insert a new row(user) to the database.[Register user]. And also I was able to log the user in.
What I am trying to do now, is retrieve a column or column from the row and display it in a text view.
For example, once I login with a user, I want to display their information from the columns, such as phone number, address, etc.
When the app is first launched, there is a registration activity. you can either register or proceed to the login activity. Once you are logged in from the login activity, there is a new activity where I want to display the information of that logged in user.

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_home);
Intent intent = getIntent();
String email = intent.getStringExtra(login.EXTRA_MESSAGE);
}
}
In the userhome.java file is where I'm having trouble at. I simply want to display the columns from the logged in user on this page.

This should get you on your way:-
Step 1.
Amend the layout to include the TextViews with id's that will be used to show the extracted data e.g. :-
<TextView
android:id="#+id/firstname"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/lastname"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/homaddress"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/phone"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/email"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/password"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
Step 2.
Add a method (added to DatabAseHelper.java although could be elsewhere like your InsertData method in MainActivity.java) to get the data as a Cursor.
e.g. :-
public Cursor getUserInfo(String email) {
SQLiteDatabase db = this.getWritableDatabase();
String whereclause = COL_6 + "=?"; //<<<< select according to email
String[] whereargs = new String[]{email};
return db.query(
TABLE_NAME,
null,
whereclause,
whereargs,
null,null,null
);
}
The above will equate to
SELECT * FROM register WHERE Email = '??????'
where ?????? will the string as passed to the method.
Step 3.
In Userhome.java declare the class variables for the TextViews, an instance of YOUR DatabaseHelper (not SQLiteOpenHelper) and the Cursor (you already have this).
e.g. :-
TextView mFirstName, mLastName, mHomeAddress, mPhone, mEmail, mPassword;
DatabaseHelper mDBHlpr;
Cursor cursor;
Step 4.
Again in UserHome.java as the onCreate method use :-
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); //<<<< USE YOUR LAYOUT
Intent intent = getIntent();
String email = intent.getStringExtra(login.EXTRA_MESSAGE);
//<<<<<<<<<< NEW CODE >>>>>>>>>>
mFirstName = (TextView) this.findViewById(R.id.firstname);
mLastName = (TextView) this.findViewById(R.id.lastname);
mHomeAddress = (TextView) this.findViewById(R.id.homaddress);
mPhone = (TextView) this.findViewById(R.id.phone);
mEmail = (TextView) this.findViewById(R.id.email);
mPassword = (TextView) this.findViewById(R.id.password);
mDBHlpr = new DatabaseHelper(this); //<<<< get Instance of DatbaseHelper
cursor = mDBHlpr.getUserInfo(email); //<<< get the Cursor according to email
if (cursor.moveToFirst()) {
mFirstName.setText(cursor.getString(cursor.getColumnIndex(DatabaseHelper.COL_2)));
mLastName.setText(cursor.getString(cursor.getColumnIndex(DatabaseHelper.COL_3)));
mHomeAddress.setText(cursor.getString(cursor.getColumnIndex(DatabaseHelper.COL_4)));
mPhone.setText(cursor.getString(cursor.getColumnIndex(DatabaseHelper.COL_5)));
mEmail.setText(cursor.getString(cursor.getColumnIndex(DatabaseHelper.COL_6)));
mPassword.setText(cursor.getString(cursor.getColumnIndex(DatabaseHelper.COL_7)));
} else {
// HANDLE NO DATA THAT MATCHES WHERE CLAUSE
mFirstName.setText("Sorry No User found that has email as :- " + email);
}
cursor.close(); //<<<< DONE WITH THE CURSOR SO CLOSE IT
}
A Cursor when returned will be positioned at a position before the first row (position -1). To get to the data you need to move to a row.
The move????? methods return true or false. The former if the move could be made (so moveToFirst, if there are no rows will return false, or true if there is at least one row). Hence how you can use if (cursor.moveToFirst()){.....}.
So if there is data (a row or more, one is assumed as there should probably not be users with the same email) the TextView's are populated (otherwise i.e. else, the firstname TextView indicates user not found (shouldn't happen though)).
Data is extracted from the Cursor using get????? (getString in this case, there are other methods such as getInt, getLong ......).
The get???? methods take an integer, the column offset (first column ID is offset 0, the 2nd firstname is offset 1 ......). However, using hard coded offsets can easily result in issues, so it's recommended to use the Cursor getColumnIndex, which returns the column offset according to the column name (more flexible).
Note how the column names are retrieved from the DatabaseHelper, using this way reduces the chance for typing errors.
You could consider changing your onCreate method in the DatabaseHelper to also utilise this single source for column names by using (replaced code commented out).
:-
#Override
public void onCreate(SQLiteDatabase db) {
String crt_sql = "CREATE TABLE " + TABLE_NAME + "(" +
// Note AUTOINCREMENT is very likely not needed
// refer to https://sqlite.org/autoinc.html
COL_1 + " INTEGER PRIMARY KEY, " +
COL_2 + " TEXT, " +
COL_3 + " TEXT, " +
COL_4 + " TEXT, " +
COL_5 + " TEXT, " +
COL_6 + " TEXT, " +
COL_7 + " TEXT " +
")";
db.execSQL(crt_sql);
/*
db.execSQL("CREATE TABLE " + TABLE_NAME + " (ID INTEGER PRIMARY KEY AUTOINCREMENT, " +
"FirstName TEXT, LastName TEXT, HomeAddress TEXT, Phone TEXT, Email TEXT, Password TEXT)");
*/
}
You may wish to have a look at SQLite Autoincrement in regads to the exclusion of the AUTOINCREMENT keyword.
You may also wish to have a look at Cursor for the numerous Cursor methods (e.g. get???? and move?????)
Testing
the above was tested by adding a user who's first name was Fred, lastname FlitStone ... using this snippet of code :-
mDBHlpr.insertUser("Fred",
"Flintsone",
"1 The Caves, Bedrock",
"01 2345 6789",
email_for_testing,
"fredflintsone"
);
resulting in :-

Above is my Database handler class, I want to grab the column PATIENT_FNAME and store all those values into an Array. Then Later on, in my AddTest.java file, i want to display these values into an spinner.
Below is my AddTest.java
package tanav.sharma;
import android.app.AlertDialog;

import android.widget.Spinner;
import android.widget.Toast;
import java.util.ArrayList;
import java.util.List;
public class AddTest extends AppCompatActivity {
private RadioGroup radioGroup;
private RadioButton radioButton;
EditText etBL, etRR, etHBR;
Spinner patients;
Context context;
PatientDbHelper patientDbHelper;
SQLiteDatabase sqLiteDatabase;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_test);
getSupportActionBar().setTitle(R.string.add_test);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
etBL = (EditText) findViewById(R.id.etBOL);
etRR = (EditText) findViewById(R.id.etRR);
etHBR = (EditText) findViewById(R.id.etHBR);
patients = (Spinner) findViewById(R.id.spinner);
}
public void addTest(View view){
radioGroup = (RadioGroup) findViewById(R.id.radio);
Button addTest = (Button) findViewById(R.id.addTest);
addTest.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int selectedId = radioGroup.getCheckedRadioButtonId();
RadioButton radioButton = (RadioButton) findViewById(selectedId);
}
});
//String BP = radioButton.getText().toString();
int BL = Integer.parseInt(etBL.getText().toString());
int RR = Integer.parseInt(etRR.getText().toString());
int HR = Integer.parseInt(etHBR.getText().toString());
patientDbHelper = new PatientDbHelper(this);
sqLiteDatabase = patientDbHelper.getWritableDatabase();
patientDbHelper.addTestInformation(BL,RR,HR,sqLiteDatabase);
Toast.makeText(getBaseContext(),"Data Saved",Toast.LENGTH_LONG).show();
patientDbHelper.close();
}
}

You can do something like
List<String> names = new ArrayList<>();
Cursor cursor = patientDbHelper.getInformations(sqLiteDatabase);
if (cursor != null){
while(cursor.moveToNext()){
names.add(cursor.getString(cursor.getColumnIndex(PatientInfo.NewPatientInfo.PATIENT_FNAME)));
}
cursor.close();
}

What should I do to correct this?

Your create table line;
db.execSQL("CREATE TABLE IF NOT EXISTS " + TABLE +
" (ID INTEGER KEY, "+COLUMN_1+ "TEXT, "+COLUMN_2 +"TEXT);");
...generates the SQL...
CREATE TABLE IF NOT EXISTS MY_TABLE (ID INTEGER KEY, TITLETEXT, STORYTEXT);
...which, due to missing spaces is not valid SQL and won't create the table.
Add the missing spaces to your create table, and it should work better.
db.execSQL("CREATE TABLE IF NOT EXISTS " + TABLE +
" (ID INTEGER KEY, "+COLUMN_1+ " TEXT, "+COLUMN_2 +" TEXT);");
CREATE TABLE IF NOT EXISTS MY_TABLE (ID INTEGER KEY, TITLE TEXT, STORY TEXT);

i think no space is there in your table creation
CREATE TABLE IF NOT EXISTS " + TABLE + " (ID INTEGER KEY, "+COLUMN_1+"
TEXT, "+COLUMN_2 +" TEXT);");
it may be better

showing the content of the table in database a list cannot be undone

I have just started to learn programming and I try to build a simple database for my exercise and I try to show all the content of the table in my database into a list in another layout but I don't know why the content isn't showing up in the list.. please help me ..
here is my apps sample
here is my activity for putting all the content in the list:

"arti", "penjelasan" }, "_id>0", null, null, null, null);

*/
String[] from = new String[] { "inggris", "arti", "penjelasan" };

*/
int[] to = new int[] { R.id.inggris, R.id.arti, R.id.penjelasan };
/* Now create a simple cursor adapter.. */
adapter = new CustomCursorAdapter(this, R.layout.baris, kamusCursor,
from, to);
// listView.setAdapter(adapter);
listContent.setAdapter(adapter);
} catch (Exception e) {
e.printStackTrace();
} finally {

}
}

here is my main activity :
package com.DennisTA;
import android.app.Activity;

}
#Override
public void onDestroy() {
super.onDestroy();
try {

db.close();
}catch (Exception e){
}
}
}

Retrieving from database as follows:
String selectQuery = "SELECT * FROM " + Variables.TABLE_ORDER
+ " WHERE " + Variables.TABLE_ORDER_CATEGORY ;
SQLiteDatabase database = dbHelper.getWritableDatabase();
Cursor cursor = database.rawQuery(selectQuery, null);
if (cursor.moveToFirst()) {
do {
HashMap<String, String> map = new HashMap<String, String>();
map.put("Food_Id", cursor.getString(0));
cart_Array_List.add(map);
} while (cursor.moveToNext());
}
cursor.close();
database.close();
}
Try extending a BaseAdapter and ovverride the following method:
#Override
public int getCount() {
return arraylist.size();
}
