}
public void deleteTask(int id){
db.delete(TODO_TABLE, ID + "= ?", new String[] {String.valueOf(id)});
}
}
Can somebody proofread this? The error is :
"no column named task in "INSERT INTO todo(status,task) VALUES (?,?)"
"android.database.sqlite.SQLiteException: table todo has no column named task (code 1 SQLITE_ERROR): , while compiling: INSERT INTO todo(status,task) VALUES (?,?)".
I also attached a ss of the error as a link.
I'm trying to create a database where I can store tasks. Does anyone has a fix for this?
Thanks!

If you're on an emulator, try reinstalling the application! It works sometimes.

Interchange ids of android database

How to go about if i want to interchange the contents of my android data base as shown below:
before
1 hello world
2 Android Nougat
after
1 Android Nougat
2 hello world

You don't need to change the positions in Database. You need to add additional int value to a database (not id). And change this value according to a new position. For first object you make it 2; for a second - 1. And when you retrieve data from your database you just sort it according to this value.
Example
String orderBy = "POSITION ASC";
Cursor cursor = database.query(TABLE_NAME, logTableColumns, null, null,
null, null, orderBy);

public class QueueDatabase extends SQLiteOpenHelper {
public QueueDatabase(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);

return true;
}

Cursor c = db.rawQuery(selectQuery, null);
if (c.moveToFirst()) {
do {
Music r = new Music();
r.setId(c.getInt(c.getColumnIndex(KEY_ID)));
r.setTitle( c.getString(c.getColumnIndex(KEY_SNAME)));
r.setArtist( c.getString(c.getColumnIndex(KEY_ANAME)));
r.setUrl(c.getString(c.getColumnIndex(KEY_URL)));
ar.add(r);
} while (c.moveToNext());
}
db.close();
return ar;
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL(CREATE_TABLE_QUEUE);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
onCreate(db);
}
public void arrange() {
SQLiteDatabase db = this.getWritableDatabase();
String[] rank = new String[]{ QueueDatabase.KEY_ID };
Cursor c = db.query(QueueDatabase.TABLE_QUEUE, rank, null, null, null, null, QueueDatabase.KEY_ORDER+" ASC");
}
}
this is how u enter data in database:
q.add(new Music(T, U, A));
qd.insertQueue(q);

Dumping android SQLite text content into textView

I built an app that so far manages to ADD text to a database (cannot verify yet but I killed the FC). However, when I try to read from the database it FCs because I'm unsure of how to use the Cursor object. I read the documentation and it confuses me more. I have a database with table "records" and a single column "texts". While my project manages to input text into the database (via an EditText), I'm trying unsuccessfully to return all the database entries from this "texts" column into a textView.
DB Helper inner-class:
private class dbHelper extends SQLiteOpenHelper {
public dbHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
System.out.println("create statement"+SQL_CREATE_ENTRIES);
try
{
db.execSQL(SQL_CREATE_ENTRIES);
}catch(SQLiteException sql)
{
sql.printStackTrace();
}
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS records");
onCreate(db);
}
public void addRecord(String t) {
ContentValues values = new ContentValues(1);
values.put(RECORDS_COLUMN_TEXTS,t);
getWritableDatabase().insert(TABLE_NAME, RECORDS_COLUMN_TEXTS, values);
}
public Cursor getRecords() {
return getWritableDatabase().rawQuery("select * from " + TABLE_NAME, null);
}
}
Within main class:
private static final int DATABASE_VERSION = 1;
private static final String DATABASE_NAME = "CSCI598";
private static final String TABLE_NAME = "records";
public static final String RECORDS_COLUMN_TEXTS = "texts";
private dbHelper openHelper;
private static final String SQL_CREATE_ENTRIES = "CREATE TABLE " + TABLE_NAME + "(" + RECORDS_COLUMN_TEXTS + " TEXT PRIMARY KEY AUTOINCREMENT" + ");";
public void onClick(View v) {
TextView tv=(TextView)findViewById(R.id.textView1);
EditText et=(EditText)findViewById(R.id.editText1);
openHelper = new dbHelper(this);
switch(v.getId()) {
case R.id.fetch1:
Cursor cursor = openHelper.getRecords();
StringBuffer sb = new StringBuffer();
cursor.moveToFirst();
while(cursor.moveToNext()) {
sb.append(cursor.getString(0) + "\n");
}
tv.setText(sb.toString());
break;
case R.id.append1:
String txt=et.getText().toString();
openHelper.addRecord(txt);
break;
}
logcat: http://pastebin.com/mqUn6g7P
As you can see, I'm probably trying something very stupid with the action for clicking the fetch button, ie. "openHelper.getRecords().toString()" attempting to convert all that Cursor returns to string. How can I go about this alternately in the simplest fashion?

Ok First you have get the strings from the Cursor by doing this
Cursor cursor = openHelper.getRecords();
StringBuffer sb = new StringBuffer();
while(cursor.moveToNext()) {
sb.append(cursor.getString(0) + "\n");
}
Then you can set it to the textView
tv.setText(sb.toString);
This should work actually
.Replace this part of your code
case R.id.fetch1:
tv.setText(openHelper.getRecords().toString());
break;
With this
case R.id.fetch1:
Cursor cursor = openHelper.getRecords();
StringBuffer sb = new StringBuffer();
while(cursor.moveToNext()) {
sb.append(cursor.getString(0) + "\n");
}
tv.setText(sb.toString);
break;
Also remove autoincrement for Text when you create the table
Replace this:
private static final String SQL_CREATE_ENTRIES = "CREATE TABLE " + TABLE_NAME + "(" + RECORDS_COLUMN_TEXTS + " TEXT PRIMARY KEY AUTOINCREMENT" + ");";
With this:
private static final String SQL_CREATE_ENTRIES = "CREATE TABLE " + TABLE_NAME + "(" + RECORDS_COLUMN_TEXTS + " TEXT" + ")";
Also Add table name in the constructor instead of database name. Change this:
public dbHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
To this:
public dbHelper(Context context) {
super(context, TABLE_NAME, null, DATABASE_VERSION);
}

How to insert data in SQLite db in Android?

I'm implementing SQLite db in my android application i want retrieve data from JSON and store in into SQLite db .I saw one of the example of using SQLite but I'm using different column name wchi is store into SQLite db .
But when i run the app I'm getting Error like =

Change this line
private static final int DATABASE_VERSION = 1;
to this
private static final int DATABASE_VERSION = 2;
And check your work again.

Try clear your app data then rerun the app, you may have had a different column before and run the app once (meaning the create table would not be called again).
