SQLite problem of no such column when trying to insert - android

I use Sqlite and I have the following DB , I am developing an application for women which it should contain a login and sign up . I had problems in the database like "no such column"

Error
E/SQLiteLog: (1) table Femme has no column named nom

Femme(nom,prenom) VALUES (?,?)
at

Method)
When I compile,it says no such column. I have defined the nom column. The database has the nom that I am trying to use for inserting but it doesn't work.

The primary issue you have is that the database helper's onCreate method is only called when the database is created, which is once in it's lifetime.
As such if any changes are made to the structure (schema) by amending the create table SQL, as used in the onCreate method, they will not be reflected unless the database is deleted or that the onCreate method is invoked some other way.
Often such changes, as least when developing the app, are applied by first doing one of the following :-
Deleting the App's data (this deletes the database, so onCreate is automatically called).
Uninstalling the App (and as a result deletes the App's data).
IF the onUpgrade method is written to drop the changed table(s) and recreate the tables (often/generally by calling the onCreate method)
After doing one of the above, rerunning the App will then result in the structure change being applied.
Note the above will result in the loss of existing data and IS NOT SUITABLE for an App that has been deployed.
In your case if using option 3, the onUpgrade method needs to include the creation of the table(s) after they have been dropped as it only drops the tables.
You code in the MainActivity is also overly complex in that it utilises opening the database without using the SQLiteOpenHelper to open the database but rather opens it using the SQLiteDatabase openOrCreate method (which doesn't result in the SQLiteOpenHelper's (DB_MJG is a subclass of SQLiteOpenHelper) onCreate method being called). However, by a quirk/luck, when you do start to use the instance of DB_MJG, namely db, as the instance was created before openOrCreate method, it actually goes on to call the onCreat method.
However, it would be much simpler, to just use one method to open the database.
As such I'd suggest implementing using just the DB_MJG DatabseHelper.
Fix
The essential fix, is to introduce the changed structure. So one of the 3, above should be taken.
if using 3. then amending the onUpgrade method to call the onCreate method and then increasing the version number would be required. That is the onUpgrade method could be :-
#Override
public void onUpgrade(SQLiteDatabase db, int i, int i1) {
db.execSQL("DROP TABLE IF EXISTS "+table_Femme);
db.execSQL("DROP TABLE IF EXISTS "+table_Enfant);
onCreate(db); //<<<<<<<<<< ADDED so that onUpgrade creates the tables after they have been dropped
}
Additional/Recommended
Close Cursor
in DB_MJG.java the getFemme method leaves the Cursor open. This can result in a too many open databases or cursors excpetion so it is suggested that the line :-
c.close();
is added to the getFemme method, so it becomes :-
public ArrayList getFemme()
{
ArrayList<Femme> femmes = new ArrayList<>();
SQLiteDatabase db = this.getWritableDatabase();
Cursor c = db.rawQuery("SELECT * FROM " +table_Femme, null);
while(c.moveToNext()){
femmes.add(new Femme(c.getString(c.getColumnIndex(NOM_F)),c.getString(c.getColumnIndex(PRENOM_F))));
}
c.close(); //<<<<<<<<<< should always close a cursor when finished with it
return femmes;
}
Note the above also does away with the need for the intermediate Femme object f.
Use DB_MJG to open the database
There is no need to openOrCreate the database when using a subclass of SQliteOpenHelper as it will do this. So MainActivity.java could be :-
public class MainActivity extends AppCompatActivity {
DB_MJG db; // Only declare the DB_MJG object.
private Button log,sign;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
db = new DB_MJG(this);
db.insertFemme(new Femme("sara","sara"));
ArrayList<Femme> femmes = db.getFemme();
TextView textView= (TextView) findViewById(R.id.textView13);
StringBuilder sb = new StringBuilder(); //<<<<<<<<<< ADDED - Use StringBuilder in a loop
for(Femme f : femmes){
sb.append("Nom: ").append(f.getNom()).append(" Prenom: ").append(f.getPrenom());
}
textView.setText(sb.toString());
}
}
Note that the above should be changed at the same time or after the fix has been applied.
Instead of concatenating Strings in a loop a StringBuilder has been used. See -Why to use StringBuffer in Java instead of the string concatenation operator

No such table: table_image (code 1): , while compiling: SELECT image_data FROM table_image WHERE image_name= ' a '

I am a bit new to SQLite so please bear with me. I am creating a table and trying to access data from it but somehow I am getting this error.
android.database.sqlite.SQLiteException: no such table: table_image (code 1): , while compiling: SELECT image_data FROM table_image WHERE image_name= ' a '
Things that I did after the error came:
1.) Uninstalled the app and installed it again.
2.) Checked for spaces in the table creation code. It looks right to me.
I am not sure why this error is appearing then. Can someone please help me.
Thanks !!
My DatabaseHelper class
public class DatabaseHelper extends SQLiteOpenHelper {
// Database Version
private static final int DATABASE_VERSION = 1;
// Database Name
private static final String DATABASE_NAME = "database_name";
// Table Names
public static final String DB_TABLE = "table_image";
// column names
public static final String KEY_NAME = "image_name";
public static final String KEY_IMAGE = "image_data";
// Table create statement
private static final String CREATE_TABLE_IMAGE = "CREATE TABLE " + DB_TABLE + " ("+
KEY_NAME + " TEXT, " +
KEY_IMAGE + " BLOB"+")";
public DatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
// creating table
db.execSQL(CREATE_TABLE_IMAGE);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// on upgrade drop older tables
db.execSQL("DROP TABLE IF EXISTS " + DB_TABLE);
// create new table
onCreate(db);
}
}
Adding stuff to db in another class
// Calling addEntry
addEntry(name, img);
// Function to add entry
public void addEntry( String name, byte[] image) throws SQLiteException {
ContentValues cv = new ContentValues();
cv.put(DatabaseHelper.KEY_NAME, name);
cv.put(DatabaseHelper.KEY_IMAGE, image);
database.insert(DatabaseHelper.DB_TABLE, null, cv);
}
Then I am tying to get data from it.
SQLiteDatabase db = openOrCreateDatabase(DatabaseHelper.DB_TABLE, MODE_PRIVATE, null);
String selectQuery = "SELECT image_data FROM "+DatabaseHelper.DB_TABLE+" WHERE image_name= ' "+"a"+" ' ";
Cursor cursor = db.rawQuery(selectQuery,null);
byte[] image = cursor.getBlob(1);
openOrCreateDatabase() is not using SQLiteOpenHelper where you have the table creation code.
To get a SQLiteDatabase managed by SQLiteOpenHelper, call e.g. getWritableDatabase() on your helper object.
After fixing that, uninstall the app once more to get rid of the empty database created by openOrCreateDatabase().
Have you tried uninstalling your app and running it again?
error says "no such table: table_image", this situation can occur if you test your app with a DB with lesser number of tables and introduce a table later on.
once you relaunch your app with an additional table an older version of DB is already present and onCreate of your DBHelper will not be called and the new table will not be added in your db.
uninstalling the app will clear any previous instance of DB and onCreate will be called again and you will start with a fresh tables.

I'm a windows phone developer and newly I started developing android apps using android studio.
I need to create a database and store in it values and retrieve the updated values on screen, so I need help in:
Creating the database.
How to show values from the database on screen?
to create database , you need to extend SQLiteOpenHelper and need a constructor that takes Context.
lets say you name this class DBOperator. The table creation process will look something like this ,
public class DbOperator extends SQLiteOpenHelper {
private static final int DATABASE_VERSION = 1;
private static final String DATABASE_NAME = "DB_NAME";
protected static final String FIRST_TABLE_NAME = "FIRST_TABLE";
protected static final String SECOND_TABLE_NAME = "SECOND_TABLE";
public static final String CREATE_FIRST_TABLE = "create table if not exists "
+ FIRST_TABLE_NAME
+ " ( _id integer primary key autoincrement, COL1 TEXT NOT NULL, COL2 TEXT NOT NULL,COL3 TEXT, COL4 int, COL5 TEXT,"
+ "COL6 TEXT,COL7 REAL, COL8 INTEGER,COL9 TEXT not null);";
public static final String CREATE_SECOND_TABLE = "create table if not exists "
+ SECOND_TABLE_NAME+.........
public DbOperator(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL(CREATE_SFIRST_TABLE);
db.execSQL(CREATE_SECOND_TABLE);
//db.close();
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
//THIS WILL BE EXECUTED WHEN YOU UPDATED VERSION OF DATABASE_VERSION
//YOUR DROP AND CREATE QUERIES
}
}
Now your data manipulation class ( add, delete , update ) will look something like this ,
public class FirstTableDML extends DbOperator {
public FirstTableDML(Context context) {
super(context);
}
private static final String COL_ID = "_id";
private static final String COL1 = "COL1";
private static final String COL2 = "COL2";
........
.......
public void deleteFirstTableDataList(List<FirstTableData> firstTableDataList) {
for (FirstTableData data : firstTableDataList)
deleteFirstTableDetailData(data);
}
public void deleteFirstTableDetailData(FirstTableData item) {
SQLiteDatabase db = this.getWritableDatabase();
db.delete(FIRST_TABLE_NAME, item.getId() + "=" + COL_ID, null);
db.close();
}
/**this method retrieves all the records from table and returns them as list of
FirstTableData types. Now you use this list to display detail on your screen as per your
requirements.
*/
public List< FirstTableData > getFirstTableDataList() {
List< FirstTableData > firstTableDataList = new ArrayList< FirstTableData >();
String refQuery = "Select * From " + FIRST_TABLE_NAME;
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = db.rawQuery(refQuery, null);
try {
if (cursor.moveToFirst()) {
do {
FirstTableData itemData = new FirstTableData();
itemData.setId(cursor.getInt(0));
itemData.setCol1(cursor.getString(1));
itemData.setCol2(cursor.getInt(2));
.....
.....
firstTableDataList.add(itemData);
} while (cursor.moveToNext());
}
} finally {
db.close();
}
Collections.sort(itemDataList);
return itemDataList;
}
public int addFirstTableData(FirstTableData data) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(COL1, data.getCol1());
values.put(COL2, data.getCol2());
.....
.....
long x=db.insert(FIRST_TABLE_NAME, null, values);
db.close();
return (int)x;
}
public void updateItemDetailData(FirstTableData data) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(COL1, data.getCol1());
values.put(COL2, data.getCol2());
values.put(COL3, data.getCol3());
.....
.....
db.update(FIRST_TABLE_NAME, values, COL_ID + "=" + data.getId(), null);
db.close();
}
}
P.S : *Data class are POJO data class representing the corresponding table.
Since you said you are not totally new to these, I have not provided any helper comments as most of the method names are self explanatory.
Hope it helps you to get started.
To creating a database for Android application, there are 2 ways:
Create database and tables using Code
Use existing database
1) Create database and tables using Code
In this scenario, you have to write a class and code to create database and tables for it. You have to use different classes and interfaces like SQLiteOpenHelper, SQLiteDatabase, etc. Check answer posted by Jimmy above.
2) Use existing database
In this scenario, you can use your existing sqlite database inside your android application. You have to place database file inside assets folder and write a code to copy that existing database on to either internal or external storage.
Regarding best scenario, I would say it's depend on the application functionality and nature, if your database is small then you should go with 1st scenario and if your database is large with many tables then you should go with 2nd scenario because you would be creating database using any GUI based SQLite browser and which would help you to make less mistakes. (When I say less mistakes using GUI, believe me there are chances of creating tables by code).
How to show values from the database on screen?
For that you have to write a SQL query which gives you Cursor in return which is a set of resultant data, so you have to iterate through the cursor data and prepare a set of data in terms of ArrayList or Array or HashMap.
You can display this set of data in ListView or GridView.
P.S. I am not posting links to any tutorials or examples as there are plenty of information/examples available on web, so suggesting you to search around the given points.
A good way to start is to read about Storage Options on the official Android documentation website: http://developer.android.com/guide/topics/data/data-storage.html

Android dev: Creating a sqlite database for word games, no user inputs

I have a simple game where users guess words. Now, I'm thinking using database to store these words to be guessed.
My problem is the tutorials that are available in the web show how to create a database and save user inputs to that database. They create, for example, a DBHelper.java in src, extends it to SQLiteOpenHelper, override the methods. Back to a specific activity, create an instance of DBHelper, then create the db, open the writable, insert user inputs, close db.
But what I think I only need to do is create a database, insert words in it, then make my app retrieve words from this database.
Am i just wondering if what i'm planning to do is right:
1. create a DBHelper.java in src, extends the class to SQLiteOpenHelper
2. define needed Strings like name of database etc.
3. Create a constructor and override the onCreate and onUpgrade methods
4. CREATE A LOADWORDS METHOD this is where i will insert my words to the database.
5. on my main activity(the first screen on my app) I will create an instance of DBHelper and call the onCreate and loadWords method.
// you would want an onCreate and onUpgrade method for best practices,, here's a partial look of what you want...
public class DBManager extends SQLiteOpenHelper
{
static final String TAG = "DBManager";
static final String DB_NAME = "words.db";
static final int DB_VERSION = 1;
static final String TABLE = "words_table";
static final String C_ID = "id";
static final String C_WORD = "word";
public DBManager(Context context)
{
super(context, DB_NAME, null, DB_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db)
{
String sql = "CREATE TABLE " + TABLE + " ("
+ C_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
+ C_WORD + " TEXT)";
db.execSQL(sql);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)
{
db.execSQL("DROP TABLE IF EXISTS " + TABLE);
onCreate(db);
}
//**** Code Insert Word and Retrieve Word Methods *****//
//**** End Code Insert Word and Retrieve Word Methods *****//

Error in Inserting values to Database

I am creating a simple Database to add the values of product. While adding the entries in database I am getting an error in Logcat and the program get stop there and then.
I am not clear with the error but its something related to insertion of data or in query I have written. I tried all possible alternatives I could.
Program Code is :

Requesting you guys to just help me to identify the error.
Thanks in Advance.
SQLiteOpenHelper onCreate() is only called if the database file does not exist. If you modify the SQL in onCreate(), you'll have to ensure the database file is updated.
Two approaches:
Delete the old version of the database. Uninstall is one way to do this. This way the database is created with whatever code you currently have in onCreate(). This is often the simplest way during app development.
Bump up the database version number you pass to SQLiteOpenHelper superclass. If this number is different from the version number stored in the database file, onUpgrade() or onDowngrade() is called, and you can update the database schema. This is the preferred way when you already have released versions out so your users can preserve their data when updating your app.
Delete your database from terminal
adb shell
cd /data/data/com.example.applicationname/databases
rm *
First you created table Books with x number of columns but pPrice column was not included in that create table query. Later on you added this column name to your create table query.
That's why this problem happened.
Try to delete the database. It will delete the old database from application and when you re start new database will be created.
onCreate() is only called if your database DOES NOT exist
Seems that your database was created without column KEY_PRICE.
After that you have altered your code adding column KEY_PRICE to String create.
If this is true you must increment database version in order it be created again:
Change:
CreateTable.DB_VERSION = 1;
To
CreateTable.DB_VERSION = 2;
As laalto suggested change onUpgrade
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + CreateTable.TABLE_NAME);
onCreate(db);
}
Check if you are missing some space. I had same problem , and solved with adding space...

how to create database once only, then read and write multiple times from it, SQLite, OpenHelper, Android

I made two classes, the main class that extends Activity and the Database class that holds the database and it's methods. parts of the code from the database class are shown below.
the SQLiteOpenHelper class is a nested class inside the database class. I took it from an example I found on the internet. inside of this nested class is the method,
db.execSQL(SCRIPT_CREATE_DATABASE);
how do I create a new database? If I instantiate the Database class from the Main class like this:
Database db = new Database(this);
does that instantiation automatically instantiate the nested SQLiteOpenHelper class too? so i don't have to explicitly do that.
however for this example of how to create a database, i am confused. if every time I instantiate a new instance calling the addNewRow() method like this:
public void addNewRow(String label, int price){
Database db = new Database(context);
db.openToWrite();
db.insertNewRow(checkBoxStatus, label, price);
db.close();
}
then a new database is created on the "new Database(context)" call, and next I add the info to enter into the columns. and finally call db.close(), however every time i call the addNewRow method shown above, it will instantiate a new database and that also instantiates SQLiteOpenhelper class so a new database is created. that means the last database has been overwritten, and my last row added has been lost, is this correct?
how do i use this Database class to create a Database only once and then read and write things from it with multiple calls like this?
Database db = new Database(context);
db.openToWrite(); or db.openToRead();
// read or update or create new row in database
db.close();
the database class:
public class Database {
public static final String MYDATABASE_NAME = "my_database";
public static final String MYDATABASE_TABLE = "my_table";
public static final int MYDATABASE_VERSION = 1;
public static final String KEY_CHECKBOX_STATUS = "check_box_status";
public static final String KEY_CHECKBOX_LABEL = "check_box_label";
public static final String KEY_PRICE = "price";
//create table MY_DATABASE (ID integer primary key, Content text not null);
private static final String SCRIPT_CREATE_DATABASE =
"CREATE TABLE " + MYDATABASE_TABLE + " (" + "ID INTEGER PRIMARY KEY AUTOINCREMENT, " +
"KEY_CHECKBOX_STATUS INTEGER, " + "KEY_CHECKBOX_LABEL TEXT, " + " KEY_PRICE INTEGER" + ");";
SQLiteDatabase sqLiteDatabase;
SQLiteHelper sqLiteHelper;
Context context;
public Database(Context c){
context = c;
}
// after this all the rest of the methods for get and set of database values
code for the SQLiteOpenHelper class, nested inside of the Database Class:
public class SQLiteHelper extends SQLiteOpenHelper {
public SQLiteHelper(Context context, String name,
CursorFactory factory, int version) {
super(context, name, factory, version);
}
#Override
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub
db.execSQL(SCRIPT_CREATE_DATABASE);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// TODO Auto-generated method stub
}
}
Yes, every time you instantiate a Database class a SQLiteHelper is instantiate. But the SQLiteHelper onCreate is only called if the database does not exist. You can test this by adding a new column to one of the table and then try to insert a row having value in this column then your app will crash. The error would be "no such column". You then need to clear your data or change the version of your database or uninstall your app to have your change table to be recreated.
Whenever you want to just open your database, you need to use this:
myDatabase = myOpenHelper.getWritableDatabase();
This won't create a new database. It would just return the instance of existing database on which you can do Read/Write operations.
Refer this to get a firm idea of how creating database works in Sqlite. Hope it helps.
private static final String SCRIPT_CREATE_DATABASE =
"CREATE TABLE IF NOT EXISTS " + MYDATABASE_TABLE + " (" + "ID INTEGER PRIMARY KEY AUTOINCREMENT, " +
"KEY_CHECKBOX_STATUS INTEGER, " + "KEY_CHECKBOX_LABEL TEXT, " + " KEY_PRICE INTEGER" + ");";
Use this query while creating the table. It will create the Table if it doesn't exist.
