Error on sqlite database creation - Android

Question

I am trying to add a new column to my sqlite database. I have previously added an extra column (email) and have had no problem at all. Below is my DbHelper class for creation.

public class DbHelper extends SQLiteOpenHelper {
public static String DATABASE_NAME="userdata";
public static final String TABLE_NAME="user";
public static final String KEY_FNAME="fname";
public static final String KEY_LNAME="lname";
public static final String KEY_EMAIL="email";
public static final String KEY_CHECK="check";
public static final String KEY_ID="id";
public DbHelper(Context context) {
    super(context, DATABASE_NAME, null, 1);

}

@Override
public void onCreate(SQLiteDatabase db) {
    String CREATE_TABLE="CREATE TABLE " +TABLE_NAME+" ("+KEY_ID+" INTEGER PRIMARY KEY, "+KEY_FNAME+" TEXT, "+KEY_LNAME+" TEXT, "+KEY_CHECK+" TEXT)";
    db.execSQL(CREATE_TABLE);

}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXISTS "+TABLE_NAME);
    onCreate(db);

}

}

When the db is created it is displayed from my mainactivity:

private void displayData() {
    dataBase = mHelper.getWritableDatabase();
    Cursor mCursor = dataBase.rawQuery("SELECT * FROM "
            + DbHelper.TABLE_NAME, null);

    userId.clear();
    user_fName.clear();
    user_lName.clear();
    user_eMail.clear();
    user_cHeck.clear();
    if (mCursor.moveToFirst()) {
        do {
            userId.add(mCursor.getString(mCursor.getColumnIndex(DbHelper.KEY_ID)));
            user_fName.add(mCursor.getString(mCursor.getColumnIndex(DbHelper.KEY_FNAME)));
            user_lName.add(mCursor.getString(mCursor.getColumnIndex(DbHelper.KEY_LNAME)));
            user_eMail.add(mCursor.getString(mCursor.getColumnIndex(DbHelper.KEY_EMAIL)));
            user_cHeck.add(mCursor.getString(mCursor.getColumnIndex(DbHelper.KEY_CHECK)));

        } while (mCursor.moveToNext());
    }
    DisplayAdapter disadpt = new DisplayAdapter(getActivity(),userId, user_fName, user_lName, user_eMail, user_cHeck);
    userList.setAdapter(disadpt);
    mCursor.close();
}
{

}

On creation i receive the following error:

CHECK is a reserved word in SQLite. Please choose a different name for this column. It will save you a lot of grief when creating other statements as well.

Something so simple can drive a man so insane. Thank you for your help.

No kidding. I once spent hours debugging only to find a misplaced character in a SQL string. Happens to all of us.

check is a reserved word in SQL. Either rename the column or quote it in ` ` backticks.
