Android database SQLite date may not be null

Android database SQLite date may not be null - java

I am attempting to update my SQLite database with a date field, using a DatePicker. for simplicties sake (on my part) I decided to just take the date and pass it to a String to update the database using just Strings (I have no desire to perform any DATETIME functions in this instance.
The datbase works (at least, via a dialog I set up) however when the data is cast to a TextView nothing appears, also eclipse stacktrace reports the following:
05-09 22:47:30.164: E/SQLiteDatabase(3112): Error inserting chest=100 arms=android.widget.TextView#4125c110 legs=100 waist=100 weight=100

Below is the class where the SQL is handled:

private static final int DATABASE_VERSION = 4;
private DbHelper ffHelper;
private final Context ffContext;
private SQLiteDatabase ffDatabase;
private static class DbHelper extends SQLiteOpenHelper {
public DbHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {

public Stats open() throws SQLException {

public long createEntry(String weight, String waist, String chest, String legs, String arms, String date) {

Cursor c = ffDatabase.query(DATABASE_TABLE, columns, null, null, null,
null, null);
String result = "";
int iRow = c.getColumnIndex(KEY_ROWID);
int iWeight = c.getColumnIndex(KEY_WEIGHT);
int iWaist = c.getColumnIndex(KEY_WAIST);
int iChest = c.getColumnIndex(KEY_CHEST);

+ " " + c.getString(iLegs)
+ " " + c.getString(iArms)
+ " " + c.getString(iDate)+ "\n";
}
return result;
}
}
The view class:
public class DBView extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.view_stats);
TextView tv = (TextView) findViewById(R.id.tvDBInfo);
Stats dbInfo = new Stats(this);
dbInfo.open();
String data = dbInfo.getData();
dbInfo.close();
tv.setText(data);
}
The EditTexts and DatePicker are in my main_activity, i can post if it would help?

You put two times the same key in your content values.
cv.put(KEY_ARMS, arms);
cv.put(KEY_ARMS, date);
Change it with :
cv.put(KEY_ARMS, arms);
cv.put(KEY_DATE, date);

You didn't insert nothing in KEY_DATE, but KEY_DATE is not null.
Yu must put cv.put(KEY_DATE, date); before insert

Instead of having your KEY_DATE column set to "TEXT NOT NULL", Just set it to plain "TEXT". You can also do that with any other columns where you may be inserting a null or empty value.

I am creating a landscape layout using fragment class. But now my code is showing error in my listMovieActivity file. I tried following some answers from stackoverflow but that didnt help me on it.

Previously, I had the same problem error inflating class fragment, but then I solved it by changing my android listview id to android custome list id. But now the problem is appearing again but this time its worst my databasehandler also is showing error it seems. Can any help me on this.

In DatabaseHandler:
private final Context context;
This makes no sense, the final field cannot be assigned.And how can you make it pass the check?
Put up MovieListFragment code, please.

SQLite Database crashes on open

I need to use a SQLite Database on my android app but when I try and open it, it crashes and I cannot figure out why. I have had a look online for the past hour and a bit but cannot find any help.
Here is the code:
public class PrivDB {
public static final String KEY_ROWID = "_id";
public static final String KEY_LEVEL = "level";
public static final String KEY_LOCKED = "locked";
public static final String KEY_SEQUENCE = "sequence";
public static final String KEY_TRIES = "tries";
private static final String DATABASE_NAME = "patdb";
private static final String DATABASE_TABLE = "tablename";
private static final int DATABASE_VERSION = 1;
private DbHelper ourHelper;
private Context ourContext;
private SQLiteDatabase ourDatabase;
private static class DbHelper extends SQLiteOpenHelper {
public DbHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
// TODO Auto-generated constructor stub
}
#Override
public void onCreate(SQLiteDatabase arg0) {
// TODO Auto-generated method stub
arg0.execSQL("CREATE TABLE " + DATABASE_TABLE + " ("+
KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, "+
KEY_LEVEL + " STRING NOT NULL, " +
KEY_LOCKED + " INTEGER NOT NULL, " +
KEY_SEQUENCE + " INTEGER NOT NULL, "+
KEY_TRIES + " INTEGER NOT NULL);");
}
#Override
public void onUpgrade(SQLiteDatabase arg0, int arg1, int arg2) {
// TODO Auto-generated method stub
arg0.execSQL("DROP TABLE IF EXISTS " + DATABASE_TABLE);
onCreate(arg0);
}
}
public PrivDB (Context c) {
ourContext = c;
}
public PrivDB open() throws SQLException {
ourHelper = new DbHelper(ourContext);
ourDatabase = ourHelper.getWritableDatabase();
return this;
}
public void close(){
ourHelper.close();
}
public long createEntry (String level, int locked, int sequence, int tries){
ContentValues cv = new ContentValues();
cv.put(KEY_LEVEL, level);
cv.put(KEY_LOCKED, locked);
cv.put(KEY_SEQUENCE, sequence);
cv.put(KEY_TRIES, tries);
return ourDatabase.insert(DATABASE_TABLE, null, cv);
}
public String getData() {
String[] columns = new String[]{KEY_ROWID, KEY_LEVEL, KEY_LOCKED, KEY_SEQUENCE, KEY_TRIES};
Cursor c = ourDatabase.query(DATABASE_TABLE, columns, null, null, null, null, null);
String result = "";
int iRow = c.getColumnIndex(KEY_ROWID);
int iLevel = c.getColumnIndex(KEY_LEVEL);
int iLocked = c.getColumnIndex(KEY_LOCKED);
int iSequence = c.getColumnIndex(KEY_SEQUENCE);
int iTries = c.getColumnIndex(KEY_TRIES);
for(c.moveToFirst(); !c.isAfterLast(); c.moveToNext()){
result = result + c.getString(iRow) + " " + c.getString(iLevel) + " " + c.getString(iLocked) + " "
+ c.getString(iSequence) + c.getString(iTries) + "\n";
}
return result;
}
public int getLocked(String s) throws SQLException {
String[] columns = new String[]{KEY_ROWID, KEY_LEVEL, KEY_LOCKED, KEY_SEQUENCE, KEY_TRIES};
Cursor c = ourDatabase.query(DATABASE_TABLE, columns, KEY_LEVEL + "=" + s, null, null, null, null);
if(c != null){
c.moveToFirst();
int locked = c.getInt(2);
return locked;
}
return (Integer) null;
}
public void updateEntry(String s, int locked, int tries) throws SQLException {
ContentValues cvUpdate = new ContentValues();
cvUpdate.put(KEY_LOCKED, locked);
cvUpdate.put(KEY_TRIES, tries);
ourDatabase.update(DATABASE_TABLE, cvUpdate, KEY_LEVEL + "=" + s, null);
}
}
and how I am calling the database:
public class Stats extends Activity {
TextView tv;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.stats);
tv = (TextView) findViewById(R.id.tvStats);
PrivDB info = new PrivDB(this);
info.open();
String data = info.getData();
info.close();
tv.setText(data);
}
}
When I open the Stats class, the app crashes, but if I comment out the info.open() until the info.close() then it works fine (but obviously nothing happens).
UPDATE
here is the log cat output:

You never pass DATABASE_TABLE name or assign it in you code. that's why it's crashing.
private static final String DATABASE_TABLE = "TABLE_NAME";
Update: do update your onCreate(). SQLite suport TEXT instedOf String
#Override
public void onCreate(SQLiteDatabase arg0) {
// TODO Auto-generated method stub
arg0.execSQL("CREATE TABLE " + DATABASE_TABLE + " ( "+
KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, "+
KEY_LEVEL + " TEXT NOT NULL, " +
KEY_LOCKED + " INTEGER NOT NULL, " +
KEY_SEQUENCE + " INTEGER NOT NULL, "+
KEY_TRIES + " INTEGER NOT NULL);");
}
Another important things you are passing the context but not saving it using static variable.
You should use like following
private static Context ourContext;
public PrivDB (Context c) {
this.ourContext = c;
}
But above all, as you are facing the error/ exception
Caused by: java.lang.StringIndexOutOfBoundsException ,
This Thrown when the a string is indexed with a value less than zero, or greater than or equal to the size of the array
I would request you to check the following so- java.lang.StringIndexOutOfBoundsException: index=0 length=0 in get sqlite database

change STRING to TEXT in below
arg0.execSQL("CREATE TABLE " + DATABASE_TABLE + " ("+
KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, "+
KEY_LEVEL + " STRING NOT NULL, " +
KEY_LOCKED + " INTEGER NOT NULL, " +
KEY_SEQUENCE + " INTEGER NOT NULL, "+
KEY_TRIES + " INTEGER NOT NULL);");
NOTE :After change please add one to your database version

I think your info is pointing to null
Try this code :
if (null != info)
{
info.open();
String data = info.getData();
info.close();
}else
Log.d("App Name", "Info is null");
One more thing for getData() function you are reading the database
so u should open the database in read mode.
ourDatabase = ourHelper.getWritableDatabase(); To
ourDatabase = ourHelper.getReadableDatabase();

#Override
public void onCreate(SQLiteDatabase arg0) {
// TODO Auto-generated method stub
arg0.execSQL("CREATE TABLE " + DATABASE_TABLE + " ("+
KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, "+
KEY_LEVEL + " STRING NOT NULL, " +
KEY_LOCKED + " INTEGER NOT NULL, " +
KEY_SEQUENCE + " INTEGER NOT NULL, "+
KEY_TRIES + " INTEGER NOT NULL);");
}
This line KEY_TRIES + " INTEGER NOT NULL);"); has two ;.Does your table get created/populated?

No column named in sqlite java

I have seen many times that I can't find the solution of no column named. Can anyone please help me?
Thank you very much in advance :)

it is because you try to get the data before checking their is data available or not.
if (cursor.moveToFirst()) {
do {
// your content
} while (cursor.moveToNext());
}
Change this block to
while (cursor.moveToNext()) {
// your content
}
Like this.
Surely this will help you.

}
And then my AddNewDay file.
public class AddNewDay {
//private variables
int _id;
String _date;
int _hours;
int _ubtillegg;
int _brutto;
// Empty constructor
public AddNewDay(){
}
// constructor
public AddNewDay(int id, String date, int hours, int ubtillegg, int brutto){
this._id = id;
this._date = date;
this._hours = hours;
this._ubtillegg = ubtillegg;
this._brutto = brutto;
}
// constructor
public AddNewDay(String date, int hours, int brutto){
this._date = date;
this._hours = hours;
this._brutto = brutto;
}
// getting ID
public int getID(){
return this._id;
}
// setting id
public void setID(int id){
this._id = id;
}
// getting date
public String getDate(){
return this._date;
}
// setting date
public void setDate(String date){
this._date = date;
}
// getting hours
public int getHours(){
return this._hours;
}
// setting hours
public void setHours(int hours){
this._hours = hours;
}
// getting ubtillegg
public int getUb(){
return this._ubtillegg;
}
// setting ubtillegg
public void setUb(int ub){
this._ubtillegg = ub;
}
// getting brutto
public int getBrutto(){
return this._brutto;
}
// setting brutto
public void setBrutto(int brutto){
this._brutto = brutto;
}
public String toString() {
return _date + " jobbet du " + _hours + " timer.";
}
}
And this is how I add a new entry in the database.
// # Makes a new object of newday.
AddNewDay newday = new AddNewDay ();
newday._date = "21.03.2013";
newday._id = 1;
newday._hours = 4;
newday._ubtillegg = 1500;
// # Open databse connection and writes new day.
DatabaseHandler connect = new DatabaseHandler (this);
connect.addDay(newday);
// # Updates the dblist with entries.
GlobalVariables.dblist = connect.getAllContacts();

So basicly I found the solution. I'm still confused about how stupid it was. And clearly database work i super-sensitive material! My problem was I forgot a white-space in the last "INTEGER" value. So instead of " INTEGER" i wrote "INTEGER", and that gave me a row called "bruttoINTEGER" instead of "brutto". So a white-space was the error. I rewrote the createTable function to this :
public void onCreate(SQLiteDatabase db) {
String CREATE_DAY_TABLE = "CREATE TABLE " + TABLE_DAYS + "("
+ KEY_ID + " INTEGER PRIMARY KEY," + KEY_DATE + " TEXT," + KEY_HOURS + " INTEGER, "
+ KEY_UB + " INTEGER," + KEY_BRUTTO + " INTEGER" + ");";
db.execSQL(CREATE_DAY_TABLE);
}

private static final int VERSION = 4;
Change the version it worked fine for me

i agree with iNzzane above. this problem is mainly caused by syntax. for example, previously my code was correct. here it is:
String CREATE_PRODUCTS_TABLE = "CREATE TABLE " + TABLE_PRODUCTS + "("
+ COLUMN_ID + " INTEGER PRIMARY KEY," + COLUMN_MESSAGEADDRESS
+ " TEXT," + COLUMN_MESSAGEBODY + " TEXT " + ")";
the above code was running correct but i added another column and it started causing the mentioned error. below is the erroneous code:
String CREATE_PRODUCTS_TABLE = "CREATE TABLE " + TABLE_PRODUCTS + "("
+ COLUMN_ID + " INTEGER PRIMARY KEY," + COLUMN_MESSAGEADDRESS
+ " TEXT," + COLUMN_MESSAGEBODY + " TEXT" + COLUMN_MESSAGETIME + " LONG" + ")";
as you can see, when i added the new column i forgot to include a comma after type TEXT. this means that when this code is executed, there will be syntax error as the compiler will read the last part as:
COLUMN_MESSAGEBODY TEXTCOLUMN_MESSAGETIME LONG
as opposed to:
COLUMN_MESSAGEBODY TEXT, COLUMN_MESSAGETIME LONG
solution: ensure that your syntax is correct and you heed to spaces and commas.

I´m not sure but maybe you forgot the " , " in the query before "ub" and "brutto" fields
String CREATE_DAY_TABLE = "CREATE TABLE " + TABLE_DAYS + "("
+ KEY_ID + " INTEGER PRIMARY KEY," + KEY_DATE + " TEXT,"
+ KEY_HOURS + " INTEGER PRIMARY KEY, " + KEY_UB + " INTEGER PRIMARY KEY, " + KEY_BRUTTO + "INTEGER PRIMARY KEY" + ")";
db.execSQL(CREATE_DAY_TABLE);

We Keep Coding

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Android database SQLite date may not be null - java

You put two times the same key in your content values. cv.put(KEY_ARMS, arms); cv.put(KEY_ARMS, date); Change it with : cv.put(KEY_ARMS, arms); cv.put(KEY_DATE, date);

You didn't insert nothing in KEY_DATE, but KEY_DATE is not null. Yu must put cv.put(KEY_DATE, date); before insert

Instead of having your KEY_DATE column set to "TEXT NOT NULL", Just set it to plain "TEXT". You can also do that with any other columns where you may be inserting a null or empty value.
