Getting error in the on create method for sqlite database

Getting error in the on create method for sqlite database - java

I am creating a trivia game for a class assignment. I initially wanted to store the questions with categories in a sqlite database. I'm strating with one table, though I want to add others for category, level, and users, but first wanted to get it working with just questions. The program compiles and installs into the emulator and the first part works fine. It's not until the app goes to create the database that I get an error. The error reads:
Caused by:
android.database.sqlite.SQLiteException: near "TABLEquestion": syntax error (code 1): , while compiling: CREATE TABLEquestion(questionIDINTEGER PRIMARY KEY,questionNameTEXT,optionATEXT,optionBTEXT,optionCTEXT,answerTEXT,questionLevelIDINTEGER,categoryIDINTEGER)
at android.database.sqlite
My code for the main activity, trivia question activity, question class, DBHelper class and the xml layout for the Trivia Question activity. Please note, the error occurs when the radio button is selected for a category, which launches the Trivia Question activity. (before adding the database, the launch worked without error). Also, I know I need to create methods for Updating and Deleting records, but wanted to get the database creation working first. I've looked at this for 2 days and cannot find the issue. Any assistance would be greatly appreciated.

The error tells you what the issue is - the SQL query is not constructed properly. There should be spaces between the individual terms - for example, CREATE TABLEquestion should be CREATE TABLE question.
Try the following line for CREATE_TABLE_QUESTION :
private static final String CREATE_TABLE_QUESTION ="CREATE TABLE "
+ TABLE_QUESTION +" ( "
+ KEY_QUESTIONID +" INTEGER PRIMARY KEY, "
+ KEY_QUESTION + " TEXT , "
+ KEY_OPTIONA + " TEXT, "
+ KEY_OPTIONB + " TEXT, "

+ KEY_ANSWER + " TEXT, "
+ KEY_LEVEL + " INTEGER, "
+ KEY_CATEGORYID + " INTEGER "+")";

how to make a search in a list view android which is populated from SQLite database

Hi to everyone I am new to android just a beginner. I am developing an app which shows a list of medicine with the brand name and generic name. I am using ListView for displaying data and this data is coming from SQLite database. What I want when a user enters a name of a medicine in a editText it should show the search result from the ListView like for example my List has a medicine name NICOX a brand name. And user wants to search this name and Enters N in the edit text then this name should be shown in the list view and all other names which start form the letter which the user enters in the edit text I added all my code here is my Main Activity code.

please help to solve this issue
I try this code and it works now I am able to filter the list but when I click on filter result the app crashed and give me a error
android.database.StaleDataException: Attempting to access a closed
CursorWindow.Most probable cause: cursor is deactivated prior to
calling this method.
at
android.database.AbstractWindowedCursor.
checkPosition(AbstractWindowedCursor.java :141)
at
android.database.AbstractWindowedCursor.
getString(AbstractWindowedCursor.java:52)
at
com.example.clnicmangmentapp.MainActivity$3.
onItemClick(MainActivity.java:97)
here is code which I try
adapter.setFilterQueryProvider(new FilterQueryProvider() {
#Override
public Cursor runQuery(CharSequence constraint) {
String search = constraint.toString();
String searchResult = (" SELECT * FROM " +
AddNewProductEntry.TABLE_NAME + " WHERE " +
AddNewProductEntry.COLUMN_PRODUCT_NAME + " LIKE '%" + search +
"%'");
return database.rawQuery(searchResult, null);
}
});
mSearchEditText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int
count) {
adapter.getFilter().filter(s);
// Don't forget to notify the adapter
adapter.notifyDataSetChanged();
}
#Override
public void afterTextChanged(Editable s) {
}
});
here I work for another code this is working code
it can filter the data but data not shown only empty list but when I click on a item it shows me correct data
public void showSearch(String search){
String searchQuery = (" SELECT * FROM " +
AddNewProductEntry.TABLE_NAME + " WHERE " +
AddNewProductEntry.COLUMN_PRODUCT_NAME + " LIKE '%" + search +
"%'");
cursor = database.rawQuery(searchQuery, null);
SimpleCursorAdapter adapterSimple = new
SimpleCursorAdapter(MainActivity.this,
android.R.layout.simple_list_item_2, cursor,
new String[] {AddNewProductEntry.COLUMN_PRODUCT_NAME,
AddNewProductEntry.COLUMN_GENERIC_NAME},
new int[] {R.id.brand_name_view, R.id.generic_name_view},
0);
listView.setAdapter(adapterSimple);
adapterSimple.notifyDataSetChanged();
}
and I use this function in my mSearchEditText like this
mSearchEditText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int
count) {
String search = s.toString();
showSearch(search);
}
#Override
public void afterTextChanged(Editable s) {
}
});
this code is working and filtring the data as I type a word but it shows empty list and when I click on this list it show me the data of that list item.

As I am already displaying list of data using my DisplayDataAdpaterView so I user this method and excecated this method in my editText search's method
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
String search = s.toString();
showSearch(search);
}
this method to search result from database and bind the views and show them as listview
public void showSearch(String search){
String searchQuery = (" SELECT * FROM " +
AddNewProductEntry.TABLE_NAME + " WHERE " +
AddNewProductEntry.COLUMN_PRODUCT_NAME + " LIKE '%" + search + "%'");
cursor = database.rawQuery(searchQuery, null);
// so this is the DisplayAdpater which already displaying data
// so we use this adapter to show search in a list view
adapter = new DispalyDataAdapterView(this,cursor);
listView.setAdapter(adapter);
adapter.notifyDataSetChanged();
}

Retrieve a specific row data in database Android

I think I have read pretty much all the answers about this topic without getting the right answer for my case.
I have a list view in one activity called Library. When I click on an item, I would like to retrieve the informations about the clicked item in another activity. I would like these information to be in different field.
You will probably understand a bit better with my code.
This is the Library activity, on which I have my listview of what I call "tags":
import android.content.Intent;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.widget.TextView;
public class InfoTagActivity extends ActionBarActivity {
TextView textTagName;
TextView textTagId;
TextView textTagData;
String tagId;
private static final String TAG_NAME = "tag_name";
private static final String TAG_MID = "tag_mid";
private static final String TAG_DATA = "tag_data";
static SQLiteDatabase db = null;
private DatabaseHelper databaseHelper;
long tag_id;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_info_tag);
getSupportActionBar().hide();
//String tagName = this.getIntent().getStringExtra(TAG_NAME);
databaseHelper = new DatabaseHelper(this);
textTagName = (TextView) findViewById(R.id.tagName);
textTagId = (TextView) findViewById(R.id.tagId);
textTagData = (TextView) findViewById(R.id.tagInfo);
Intent intent = getIntent();
Cursor cursor = databaseHelper.getAllData();
if (cursor != null && cursor.moveToFirst()) {
String name = cursor.getString(cursor.getColumnIndex("tag_name"));
textTagName.append(name);
String id = cursor.getString(cursor.getColumnIndex("tag_mid"));
textTagId.append(id);
String info = cursor.getString(cursor.getColumnIndex("tag_data"));
textTagData.append(info);
}
}
}
DatabaseHelper.java :
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;
public class DatabaseHelper {
private static final String TAG = DatabaseHelper.class.getSimpleName();
// database configuration
// if you want the onUpgrade to run then change the database_version
private static final int DATABASE_VERSION = 1;
private static final String DATABASE_NAME = "mydatabase.db";
// table configuration
public static final String TABLE_NAME = "person_table"; // Table name
private static final String TAG_ID = "_id"; // a column named "_id" is required for cursor
private static final String TAG_NAME = "tag_name";
private static final String TAG_MID = "tag_mid";
private static final String TAG_DATA = "tag_data";
private DatabaseOpenHelper openHelper;
private SQLiteDatabase database;
// this is a wrapper class. that means, from outside world, anyone will communicate with PersonDatabaseHelper,
// but under the hood actually DatabaseOpenHelper class will perform database CRUD operations
public DatabaseHelper(Context aContext) {
openHelper = new DatabaseOpenHelper(aContext);
database = openHelper.getWritableDatabase();
}
public void insertData (String aTagName, String aTagId, String aTagData) {
// we are using ContentValues to avoid sql format errors
ContentValues contentValues = new ContentValues();
contentValues.put(TAG_NAME, aTagName);
contentValues.put(TAG_MID, aTagId);
contentValues.put(TAG_DATA, aTagData);
database.insert(TABLE_NAME, null, contentValues);
}
public Cursor getAllData () {
String buildSQL = "SELECT * FROM " + TABLE_NAME;
Log.d(TAG, "getAllData SQL: " + buildSQL);
return database.rawQuery(buildSQL, null);
}
// this DatabaseOpenHelper class will actually be used to perform database related operation
private class DatabaseOpenHelper extends SQLiteOpenHelper {
public DatabaseOpenHelper(Context aContext) {
super(aContext, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase sqLiteDatabase) {
// Create your tables here
String buildSQL = "CREATE TABLE " + TABLE_NAME + "( " + TAG_ID + " INTEGER PRIMARY KEY, " +
TAG_NAME + " TEXT, " + TAG_MID + " TEXT, " + TAG_DATA + " TEXT )";
Log.d(TAG, "onCreate SQL: " + buildSQL);
sqLiteDatabase.execSQL(buildSQL);
}
#Override
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int oldVersion, int newVersion) {
// Database schema upgrade code goes here
String buildSQL = "DROP TABLE IF EXISTS " + TABLE_NAME;
Log.d(TAG, "onUpgrade SQL: " + buildSQL);
sqLiteDatabase.execSQL(buildSQL); // drop previous table
onCreate(sqLiteDatabase); // create the table from the beginning
}
}
}
And InfoTagActivity.java , this is in this activity that I want to get the information about the clicked item :
public class InfoTagActivity extends ActionBarActivity {
TextView textTagName;
TextView textTagId;
TextView textTagData;
String tagId;
private static final String TAG_NAME = "tag_name";
private static final String TAG_MID = "tag_mid";
private static final String TAG_DATA = "tag_data";
static SQLiteDatabase db = null;
private DatabaseHelper databaseHelper;
long tag_id;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_info_tag);
getSupportActionBar().hide();
//String tagName = this.getIntent().getStringExtra(TAG_NAME);
databaseHelper = new DatabaseHelper(this);
textTagName = (TextView) findViewById(R.id.tagName);
textTagId = (TextView) findViewById(R.id.tagId);
textTagData = (TextView) findViewById(R.id.tagInfo);
Intent intent = getIntent();
Cursor cursor = databaseHelper.getAllData();
if (cursor != null && cursor.moveToFirst()) {
String name = cursor.getString(cursor.getColumnIndex("tag_name"));
textTagName.append(name);
String id = cursor.getString(cursor.getColumnIndex("tag_mid"));
textTagId.append(id);
String info = cursor.getString(cursor.getColumnIndex("tag_data"));
textTagData.append(info);
}
}
}
With the associated activity_info_tag.xml :
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/relativeLayout"
android:layout_alignParentRight="true"

<TextView

android:paddingLeft="5dp"

android:layout_toRightOf="#+id/tagInfoText"
android:layout_toEndOf="#+id/tagInfoText"
android:paddingLeft="5dp"
android:paddingRight="5dp"
/>
</RelativeLayout>
My problem is that by now, when I click on a tag of the list view, it always give me the information about the first tag only. I would like to get the information about the tag on which I clicked instead.
Could someone help me on that ?
Thank you a lot for your answers !

Trying to make a sqlite database search app

I'm new to Android and have been working on this app for a while. Pretty much I'm loading initial values into the sqlite database with 3 columns: _id, product, and ingredients. I have an EditText box for the user to search the products to see if they have a certain ingredient in it. A listview is then printed out showing the products with these ingredients. I'm having some overall trouble with this code, specifically when I run it, it shows "Could not read row 0 col 1" from logcat.
Update: Thanks to Todd I fixed my original "Could not read row 0 and col 1" problem but now when I click the search button with edit text input "Apple" (which should output one product), the app doesn't update and stays static. Any help would be appreciated!

Failed to read row 0, column 1 from a CursorWindow which has 3 rows, 1 columns.
I think your query needs to return more columns...
In getSearchedProducts() you select only the product column:
// Select a single column.
Cursor cursor = database.rawQuery("SELECT product FROM products WHERE ingredients like ?", args);
But in cursorToProduct() you read two columns (ID and Product):
product.setId(cursor.getLong(0));
product.setProduct(cursor.getString(1));
It looks like you need to add the Id to the query.
Cursor cursor = database.rawQuery("SELECT id, product FROM products WHERE ingredients like ?", args);

no such column: KEY_PUBNAME

Im making an app which stores data in an SQLite database. I want to be able to add, edit and delete data from this database. I can app to it no problem. I am currently working on trying to delete from the database but I keep getting the same error.
(1) no such column: KEY_PUBNAME
Here is my Java file:
package com.example.beer_budget3;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.Toast;
import android.content.Intent;
//Need to update delete layout after deleting row
public class Delete extends Activity
{
//Creating an object name for my database
DatabaseSetup2 db = new DatabaseSetup2(this);
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
//This page layout is located in the delete XML file
setContentView(R.layout.delete);//Put one of these in each class
//Delete button that has been created in the delete XML file
Button delete = (Button)findViewById(R.id.deletepub);
delete.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
//This page links back to the MainMenu page
Intent i = new Intent(Delete.this, MainMenu.class);
//Calling the deleting function
deleting(v);
//Activating the intent
startActivity(i);
}
});
}
public void deleting(View v)
{
db.open();
//Save user input into rowId
EditText pnametxt = (EditText)findViewById(R.id.delete1);
//Open the database
String pname2 = pnametxt.getText().toString();
db.deletePub(pname2);
db.close();
}
}
Here is my XML file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

And here is my database adapter:

public static final String KEY_PRICE = "Price";
private static final String DATABASE_NAME = "CillinsAssignment";
private static final String DATABASE_TABLE = "Beer_Budget";
private static final int DATABASE_VERSION = 1;
// This is the string containing the SQL database create statement
private static final String DATABASE_CREATE = "CREATE TABLE " + DATABASE_TABLE +
"( " +KEY_ROWID + " integer primary key autoincrement, "+KEY_PUBNAME +" text not
null, "+KEY_LOCATION+" text not null, "+KEY_PRICE+ " text not null);";
private final Context context;
private DatabaseHelper DBHelper;
// utility class that makes it easy to create and maintain an SQLLite database
private SQLiteDatabase db;//Class containing methods to manage a local SQLLite Database file
// constructor for your class
public DatabaseSetup2(Context ctx)
{
// Context is a way that Android transfers info about Activities and apps.
this.context = ctx;
DBHelper = new DatabaseHelper(context);
}
// This is the helper class that will create the dB if it doesn’t exist and
//upgrades it if the structure has changed. It needs a constructor, an
//onCreate() method and an onUpgrade() method
private static class DatabaseHelper extends SQLiteOpenHelper
{
// constructor for your dB helper class. This code is standard. You’ve set
//up the parameter values for the constructor already…database name,etc
DatabaseHelper(Context context)
{
super(context, DATABASE_NAME, null, 1);
}
#Override
public void onCreate(SQLiteDatabase db)
{
// The “Database_create” string below needs to contain the SQL
//statement needed to create the dB
try
{
db.execSQL(DATABASE_CREATE);
}
catch (SQLException e)
{
e.printStackTrace();
}
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)
{
// If you want to change the structure of your database, e.g.
// Add a new column to a table, the code will go head..
//This method only triggers if the database version number has
//increased
Log.w("test", "Upgrading database from version " + oldVersion + " to "

db.execSQL("DROP TABLE IF EXISTS Beer_Budget");
onCreate(db);
}
}// end of the help class
// from here on, include whatever methods will be used to access or change data
//in the database
//---opens the database--- any activity that uses the dB will need to do this
public DatabaseSetup2 open() throws SQLException
{
db = DBHelper.getWritableDatabase();
return this;
}
//---closes the database--- any activity that uses the dB will need to do this
public void close()
{
DBHelper.close();
}
//---insert a pub into the database---
public long insertPub(String Pub_Name, String Location, String Price)
{
ContentValues initialValues = new ContentValues();
initialValues.put(KEY_PUBNAME, Pub_Name);
initialValues.put(KEY_LOCATION, Location);
initialValues.put(KEY_PRICE, Price);
return db.insert(DATABASE_TABLE, null, initialValues);
}
//---deletes a particular pub---
public boolean deletePub(String Pub_Name)
{
//delete statement. If any rows deleted (i.e. >0), returns true
return db.delete(DATABASE_TABLE, "KEY_PUBNAME = "+ Pub_Name+" ", null) > 0;
}
//---retrieves all the rows---
public Cursor getAllPubs()
{
return db.query(DATABASE_TABLE, new String[]
{
KEY_ROWID,
KEY_PUBNAME,
KEY_LOCATION,
KEY_PRICE},
null,
null,
null,
null,
null);
}
//---retrieves a particular row---
public Cursor getPub(int _id) throws SQLException
{
Cursor mCursor = db.query(DATABASE_TABLE, new String[]
{
KEY_ROWID,
KEY_PUBNAME,
KEY_LOCATION,
KEY_PRICE
},
KEY_ROWID + "=" + _id,
null,
null,
null,
null
);
if (mCursor != null) {
mCursor.moveToFirst();
}
return mCursor;
}
}
KEY_PUBNAME is clearly declared in the database adapter.
Any help would be great.

If you see your DatabaseHelper, you've defined following:
//---deletes a particular pub---
public boolean deletePub(String Pub_Name)
{
//delete statement. If any rows deleted (i.e. >0), returns true
return db.delete(DATABASE_TABLE, "KEY_PUBNAME = "+ Pub_Name+" ", null) > 0;
}
The keyname you've mentioned is KEY_PUBNAME. However where you've created the table, the keyname you've defined is Pub_Name. Over here:
public static final String KEY_PUBNAME = "Pub_Name";
That's why its not found. KEY_PUBNAME is the variable you've declared and not the name of the column. You may want to try to change it in db.delete statement.
