Android - SQLiteDatabase no such table error(code 1)

Question

I've a ListView in my app to which the user can Add/Remove items. I'm using SQLiteDatabase to store the items when app is not in use but, the SQLiteDatabase giving me a strange error saying "No such table found:subjects(code 1). I can't figure out why's this happening, I've used SQLiteDatabase a few times before, but this time around it's just not working.

This is my code:

SubjectsDatabase.java -

import java.util.ArrayList;

import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class SubjectsDatabase extends SQLiteOpenHelper {

private static final String SUBJECT_ID = "id";
private static final String SUBJECT_NAME = "name";

private static final String DATABASE_NAME = "subjectsDatabase";
private static final String TABLE_SUBJECTS = "subjects";
private static final int DATABASE_VERSION = 1;

private static final String DATABASE_CREATE = "CREATE_TABLE" + TABLE_SUBJECTS + "(" + 
                        SUBJECT_ID + "INTEGER_PRIMARY_KEY, " + SUBJECT_NAME + "TEXT" + ")";
public SubjectsDatabase(Context context) {
    super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
    try {
        db.execSQL(DATABASE_CREATE);
    }
    catch(SQLException e) {
        e.printStackTrace();
    }
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

    db.execSQL("DROP TABLE IF EXSISTS topics");
    onCreate(db);
}
public void addSubject(Subject subject) {
    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues topics = new ContentValues();
    topics.put(SUBJECT_NAME, subject.getSubject());

    db.insert(TABLE_SUBJECTS, null, topics);
    db.close();
}
public void removeSubject(Subject subject) {

    SQLiteDatabase db = this.getWritableDatabase();

    db.delete(TABLE_SUBJECTS, SUBJECT_NAME + " = ?", 
            new String[] {String.valueOf(subject.getSubject())});

    db.close();
}
public ArrayList<Subject> getSubjects(){

    ArrayList<Subject> topics = new ArrayList<Subject>();

    String selectQuery = "SELECT * FROM " + TABLE_SUBJECTS;

    SQLiteDatabase db = this.getWritableDatabase();
    Cursor cur = db.rawQuery(selectQuery, null);

    if(cur.moveToFirst()) {
        do {
            Subject subject = new Subject();
            subject.setId(Integer.parseInt(cur.getString(0)));
            subject.setSubject(cur.getString(1));
            topics.add(subject);
        } while(cur.moveToNext());
    }
    db.close();
    return topics;
}
public void updateSubject(Subject old_name, Subject new_name) {
    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues topic = new ContentValues();

    topic.put(SUBJECT_NAME, new_name.getSubject());

    db.update(TABLE_SUBJECTS, topic, SUBJECT_NAME + " = ?", 
            new String[] {String.valueOf(old_name.getSubject())});
    db.close();
}
}

Subject.java -

public Subject(String subject) {
    this._subject = subject;

It's an easy fix: you miss a space here (and have an extra UNDERSCORE):

"CREATE_TABLE" + TABLE_SUBJECTS + "("

and here (and have extra UNDERSCOREs)

SUBJECT_ID + "INTEGER_PRIMARY_KEY, "

and here

SUBJECT_NAME + "TEXT"

It should read:

"CREATE TABLE " + TABLE_SUBJECTS + " (" // Note: NO UNDERSCORE!

and

SUBJECT_ID + " INTEGER PRIMARY KEY, " // Note: NO UNDERSCORES!

and

SUBJECT_NAME + " TEXT"

The table isn't created because of the erroneous CREATE TABLE syntax.

I just tried to run it again after adding the space.... But still it's crashing!!

remove your old application and then run again.

I edited my answer, to add the other missing spaces and remove the underscores

I have no doubt... ;)

change this line to

private static final String DATABASE_CREATE = "CREATE_TABLE" + TABLE_SUBJECTS + "(" SUBJECT_ID + "INTEGER_PRIMARY_KEY, " + SUBJECT_NAME + "TEXT" + ")";

to

private static final String DATABASE_CREATE = "CREATE TABLE" + TABLE_SUBJECTS + "(" + 
                    SUBJECT_ID + " INTEGER_PRIMARY_KEY, " + SUBJECT_NAME + " TEXT" + ")";

you need to add space after columname and datatype. Then uninstall your previous app and run it again

Why don't you check your SQLite db from Eclipse's DDMS perspective -> File Explorer. Download to your desktop and check using any SQLite browser tool.

If you find table is missing, you need to add try - catch blocks while creating your table (and everywhere else as recommendation) and log the exception so you know what is happening behind the scene. db.execSQL throws android.database.SQLException; and hence you can catch it.

Further, load_library(linker.cpp:759): library "libmaliinstr.so" not found error is related to missing permissions: RECORD_AUDIO & WRITE_EXTERNAL_STORAGE. Permissions needs to be added to AndroidManifest.xml file.

Note: If you use log several exceptions in your code, don't forget to disable logging while publishing your app.

Further, what I suspect is that earlier you had topics table and then you modified TABLE_SUBJECTS variable to subjects. Your database actually has topics table and now you are trying to access subjects table ! I am guessing this because you have topics table specified in your onUpgrade method !

- are you sure?
