    I suggest function updateData like below, it returns integer.
    public int updateData (String id, String name, String surname, String marks) {
    db = this.getWritableDatabase();
    ContentValues contentValues = new ContentValues();
    contentValues.put(COL_1, id);
    contentValues.put(COL_2, name);
    contentValues.put(COL_3, surname);
    contentValues.put(COL_4, marks);
    String[] IDs = {id};
    return db.update(TBL_NAME, contentValues,"ID = ?",IDs); // successfull return 1 else return 0
    }
    Then on the calling method

    if (isUpdate == 1)
    Toast.makeText(MainActivity.this, "Data updated.", Toast.LENGTH_LONG).show();
    else
    Toast.makeText(MainActivity.this, "ID not found.nData not updated.", Toast.LENGTH_LONG).show();
    So if update succesfull the function updateData will return 1 else 0.

    Good example. However there is a bug in code.
    As is code in class DatabaseHelper.java =>
    public boolean updateData(…
    …etc..

    db.update(TABLE_NAME, contentValues, "ID = ?",new String[] { id });
    return true;

    To be code in class DatabaseHelper.java =>
    public boolean updateData(…
    …etc..

    int lint =
    db.update(TABLE_NAME, contentValues, COL_1 + " = ?", new String[]{id});

    if (lint == 0) return false;
    else return true;

    The update doesn't work properly in case wrong id is inserted. It still shows updated successfully. To solve this, take result of db.update() in an int variable. Compare this value with 0, if it is greater than 0 return true else return false.

    Hello! Thank you for this tutorial … I need to update a single value on a specific row … how could I do? Thanks!

    Reply
  29. TheHumanBeingofEarth Posted on July 9, 2020 at 12:19 am

    variable isUpdate will always have the value true because u have forced the method to return true, so by default, it is going to always return true even if the update is successful or not. Seems like, in that case, using Toast will confuse rather than helping with a message. You need to fix ur method.

    android.database.sqlite.SQLiteException: near "fromstudent_table": syntax error (code 1): , while compiling: select * fromstudent_table

    could it be this part?

    AS 2.2.1 is so awesome and powerful that following source codes are given automatically:
    public Cursor getAllData() {
    SQLiteDatabase db = this.getWritableDatabase();
    Cursor res = db.rawQuery("select * from "+TABLE_NAME,null);
    return res;
    }

    public boolean updateData(String id,String name,String surname,String marks) {
    SQLiteDatabase db = this.getWritableDatabase();
    ContentValues contentValues = new ContentValues();
    contentValues.put(COL_1,id);
    contentValues.put(COL_2,name);
    contentValues.put(COL_3,surname);
    contentValues.put(COL_4,marks);
    db.update(TABLE_NAME, contentValues, "ID = ?",new String[] { id });
    return true;
