The error is clear:
...
.sqlite.SQLiteException: table userInfo has no column named userInfo (code 1):
, while compiling: INSERT INTO userInfo(password,userInfo) VALUES (?,?) at
...
When you are invoking the method
public boolean addInfo( ContentValues values )
You are passing as a content value, a value named with the same name as the table. You have to check two things:
Where you are using UserProfile.Users.TABLE_NAME (that I suppose it has the value userInfo
Check what you are passing to content values used by addInfo method.
Hope it helps.

If you are trying to add new row to the table after it has been created, try to remove the table and create it again.
to remove
sqLiteDatabase.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);
after this, you can recreate the table again

You have to increase your version of database after then do changes in On-upgrade method of sqlite.
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
if(newVersion > oldVersion){
db.execSQL("DROP TABLE IF EXISTS " +......);
db.execSQL("CREATE TABLE IF NOT EXISTS " +......);
insertColumnIfNotAvailableinTable(SQLiteDatabase db, String tableName, String columnName, String columnType);
}
}

How to move data to SQLite?

Code
public class SettingsContacts extends AppCompatActivity {

private List<ContactsHelper> contacts = new ArrayList<>();
private LinearLayoutManager linearLayoutManager;
private ContactsAdapter mAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

This displays all the contacts in the users phone in an activity... How do i move the data into a table in SQLite?
Progress so far:
public class DatabaseHelper extends SQLiteOpenHelper {
// Table Name
public static final String TABLE_NAME = "Contacts";
// Table columns
public static final String ID = "ID";
public static final String Contact_Name = "Contact_Name";
public static final String Phone_Number = "Phone_Number";
// Database Information
static final String DB_NAME = "MessagePlus_Contacts";
// database version
static final int DB_VERSION = 1;
// Creating table query
private static final String CREATE_TABLE = "Create Table " + TABLE_NAME + "(" + ID
+ " INTEGER PRIMARY KEY AUTOINCREMENT, " + Contact_Name + " TEXT NOT NULL, " + Phone_Number + " INT NOT NULL);";
public DatabaseHelper(Context context) {
super(context, DB_NAME, null, DB_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL(CREATE_TABLE);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);
onCreate(db);
}
Helper
public class ContactsHelper {
private String Name;
private String PhoneNumber;
public ContactsHelper() {
}
public ContactsHelper(String Name, String PhoneNumber) {
this.Name = Name;
this.PhoneNumber = PhoneNumber;
}
public String getName() {
return Name;
}
public void setName(String Name) {
this.Name = Name;
}
public String getPhoneNumber() {
return PhoneNumber;
}
public void setPhoneNumber(String PhoneNumber) {
this.PhoneNumber = PhoneNumber;
}
}
I've got to this point but I don't know how to proceed because I have so far only worked with adding/modifying data by clicking a button or similar to that.
How do I move the complete data to SQLite and when new contact is added obviously it wont get added to table automatically so when I add a feature like swipe to refresh I want the new contact to be added to the data as well?

Solution:
Add this method in your DatabaseHelper class:
public void insertData(String contactName, String phoneNumber) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(DatabaseHelper.Contact_Name, contactName);
values.put(DatabaseHelper.Phone_Number, phoneNumber);
db.insert(DatabaseHelper.TABLE_NAME, null, values);
// close db connection
db.close();
}
then, Firstly, make DatabaseHelper global object in your SettingsContacts class:
public DatabaseHelper database;
Add this in youronCreate()
database = new DatabaseHelper(SettingsContacts.this);
then after this, add the below line in addDataToList() method as shown:
Add this line:
database.insertData(name, phoneNumber)
as shown in below code (Write Here):
if (phoneCursor != null) {
if (phoneCursor.moveToNext()) {
String phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
contacts.add(new ContactsHelper(name, phoneNumber));
phoneCursor.close();
....... (Write Here)
}
}
That's it.
Hope it works.
To see if the data is already inserted, you can check the count of your table:
public int getCount() {
String countQuery = "SELECT * FROM " + DatabaseHandler.TABLE_NAME;
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery(countQuery, null);
int count = cursor.getCount();
cursor.close();
// return count
return count;
}
Write the above method in you Database Handler class.
Then, in your activity after calling insertData(..), you can write like:
int count = database.getCount();
Log.e("Count From DB: ", String.valueOf(count));

Android sqlite:could not execute method onclick

I'm trying to login using the database by using the id of the specific members.
But the app crashes with log error.
Following various other similar errors, I included "c1.movetoFirst();" and "c2.movetoFirst();". But still its not working.

Where is the error? And how can it be recitified?

You better check whether cursor has next before invoking movetoFirst as in
Cursor c1 = mydb.getEmail(email);
if(c1.getcount() > 0)
c1.moveToFirst();
and make sure, email id is already in database and check for case sensitive.

This is common occurrence if the Course column is a recent addition to your database, but you forgot to increment the database version.
With the code you have, bumping your database version will wipe the database and recreate the database with the correct columns.
Alternatively, uninstalling and reinstalling your app should fix it.

You probably added that column after a previous run, when the database was already created.
Solution: Uninstall and reinstall your app.
Alternate solution: Increase the DATABASE_VERSION constant value.

message=(TextView)findViewById(R.id.logResult);
message.setText("");
db.insertContact("jon","9595749944","r#hotmail.com","a","usa");
login.setOnClickListener(new View.OnClickListener() {
#Override

String pass = password.getText().toString();
int id = Integer.parseInt(student_id.getText().toString());
int result= db.numberOfRows();
if (result == 1) {
message.setText("Invalid User");
} else {
message.setText("valid User" );
}
}
});
}
But,When the button is pressed the insertion in not occur and app close
where is the problem?? help?????????????? I want to insert data in database when the app is created how?

your call is outside of the onclick , first try:
login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
db.insertContact("jon","9595749944","r#hotmail.com","a","usa");
}
});

Improve this question
Im trying to store data from some editTexts on a local android database and then eventually show it on a listview, but right now Im getting an error that says a column doesnt exist, I was following a tutorial on android hive so some of the variable names might look weird, but everything should be accurate.

Uninstall your app so the onCreate() is run again. See
When is SQLiteOpenHelper onCreate() / onUpgrade() run?
for more about that.
