set boolean value in sqlite android - android-sqlite

I have column which is supposed to contain the true and false value in db. I understand that they should be in form of 0 and 1. I have an int column "status" but it always returns zero.
#Override
public void onCreate(SQLiteDatabase db) {
String create_table = "CREATE TABLE " + TABLE_NAME + "( "
+ "ID INTEGER PRIMARY KEY ,"
+ VALUE + " TEXT NOT NULL, "
+ STATUS + " INTEGER NOT NULL)";
db.execSQL(create_table);
}
public int getStatus(String _id,int status)
{
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery("SELECT " + STATUS + " FROM "
+TABLE_NAME+" WHERE " + _ID +" =? " , new String[] {_id});
if(cursor.moveToFirst()){
return cursor.getInt(cursor.getColumnIndex(STATUS));
} else {
return 0;
}
}
I need to set to true in the case below but item_status returns zero everytime. I checked the db and there is NULL in the whole status column.
if (success) {
status = 1;
int item_status = db.getStatus(fetchId(),status);
Toast.makeText(this, " item_status " + item_status , Toast.LENGTH_SHORT).show();
}

Creating new Objects in JPQL returns only one object

I have a JPA Entity with a large number of fields and millions of records. For a report, I need only some of the fields. So I want to create an Object with the essential fields due to resource constraints. I tried to create a list of new objects in JPQL. It gives only one object as a result, where multiple objects are expected.
String j;
j = "select new lk.gov.health.phsp.pojcs.ClientEncounterComponentBasicDataToQuery("
+ "f.name, "
+ "f.code, "
+ "f.item.code, "
+ "f.shortTextValue, "
+ "f.integerNumberValue, "
+ "f.longNumberValue, "
+ "f.realNumberValue, "
+ "f.booleanValue, "
+ "f.dateValue, "
+ "f.itemValue.code"
+ ") ";
j += " from ClientEncounterComponentItem f "
+ " where f.retired=false "
+ " and f.encounter.id=:eid";
Map m = new HashMap();
m.put("eid", endId);
The EBJ is as follows.
public List<Object> findObjects(String jpql, Map<String, Object> parameters, TemporalType tt) {
TypedQuery<Object> qry = getEntityManager().createQuery(jpql, Object.class);
Set s = parameters.entrySet();
Iterator it = s.iterator();
while (it.hasNext()) {
Map.Entry m = (Map.Entry) it.next();
Object pVal = m.getValue();
String pPara = (String) m.getKey();
if (pVal instanceof Date) {
Date pDate = (Date) pVal;
qry.setParameter(pPara, pDate, TemporalType.DATE);
} else {
qry.setParameter(pPara, pVal);
}
}
try {
return qry.getResultList();
} catch (Exception e) {
return null;
}
}
What am I doing wrong? I am using EclipseLink as the persistence provider.

'DATE' cannot hold values of type 'INTEGER'

I've set up an SQL database and used 'Date' as my column header which obviously has its own format as opposed to integer or char etc. However when I put in a date such as 2/11/2016 it gives me the error message - 'DATE' cannot hold values of type 'INTEGER'. Does anyone know what code I should be using? Here's my jsp below. All goes into DB when I remove all reference to date.

How to solve a TabLayout inside a Fragment which includes four Tabs created by one Fragment with newInstance() using RecyclerView

I implement an Activity which contains a NavigationView with includes several fragments. The first Fragment of the NavigationView contains a RecyclerView with a TabLayout, so that I can swipe between the different lists. Because I've got always the same list(UI) with different values, I decided to implement only one Fragment with a newInstance().
My problem now is that the list does not update properly when I jump from Tab1 to Tab2 or if I change a list item and come back to the list. Can somebody help me? I can't figure it out ...
swipe from Tab1 to Tab2
This is my fragment which contains the RecyclerView:
public class HinweiseFragment extends Fragment {
private static final String TAG = "HinweiseFragment";
private TabLayout mTabLayout;
private ViewPager mViewPager;
private HinweiseTabAdapter adapter;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
((MainActivity) getActivity()).getSupportActionBar().setTitle("Hinweise");
((MainActivity) getActivity()).showFloatingActionButton();
View rootView = inflater.inflate(R.layout.fragment_hinweise, null);
mTabLayout = (TabLayout) rootView.findViewById(R.id.tablayout_hinweise);
mTabLayout.addTab(mTabLayout.newTab().setText("BESAMUNG"));
mTabLayout.addTab(mTabLayout.newTab().setText("NICHT BESAMEN"));
mTabLayout.addTab(mTabLayout.newTab().setText("VERDACHT"));
mTabLayout.addTab(mTabLayout.newTab().setText("ALLE"));
mTabLayout.setTabGravity(mTabLayout.GRAVITY_FILL);
mViewPager = (ViewPager) rootView.findViewById(R.id.viewpager_hinweise);
adapter = new HinweiseTabAdapter(getChildFragmentManager(), mTabLayout.getTabCount(), getContext());
mViewPager.setAdapter(adapter);
mViewPager.setOffscreenPageLimit(3);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(mTabLayout));
mTabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
mViewPager.setCurrentItem(tab.getPosition(), true);
adapter.refreshFragment(tab.getPosition());
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
return rootView;
}
}
This is my TabAdapter:
public class HinweiseTabAdapter extends FragmentPagerAdapter {
HinweiseListFragment tab_besamung, tab_nicht, tab_verdacht, tab_alle;
String[] tabHostTitle = {"BESAMUNG", "NICHT BESAMEN", "VERDACHT", "ALLE"};
int mNumOfTabs;
private final Context mContext;
public HinweiseTabAdapter(FragmentManager fm, int NumOfTabs, Context context) {
super(fm);
this.mNumOfTabs = NumOfTabs;
this.mContext = context;
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
tab_besamung = HinweiseListFragment.newInstance(0, "BESAMUNG");
return tab_besamung;
case 1:
tab_nicht = HinweiseListFragment.newInstance(1, "NICHT BESAMEN");
return tab_nicht;
case 2:
tab_verdacht = HinweiseListFragment.newInstance(2, "VERDACHT");
return tab_verdacht;
case 3:
tab_alle = HinweiseListFragment.newInstance(3, "ALLE");
return tab_alle;
default:
return null;
}
}
public void refreshFragment(int position) {
switch (position) {
case 0:
tab_besamung.update();
break;
case 1:
tab_nicht.update();
break;
case 2:
tab_verdacht.update();
break;
case 3:
tab_alle.update();
break;
}
}
#Override
public int getItemPosition(Object object) {
int position = getItemPosition(object);
if (position >= 0) {
return position;
} else {
return POSITION_NONE;
}
}
#Override
public int getCount() {
return mNumOfTabs;
}
#Override
public CharSequence getPageTitle(int position) {
return tabHostTitle[position];
}
}
and this is my Fragment which contains the List:

Select results truncated without error message

I'm using Google Cloud SQL from an App Engine application via Java and JDBC.
I select rows of a table using following code:
public void processGcmRegistrations(String whereCondition, String appName,
String[] appVariants, boolean onlyTestDevices,
String orderByCondition,
GcmRegistrationProcessor processor) throws DbException {
if (whereCondition == null && appName == null)
throw new IllegalArgumentException("One of the parameters \"whereCondition\", " +
"\"appNmae\" must not be null.");
if (whereCondition == null) {
whereCondition = "APP_NAME = '" + appName + "' " +
createInListCondition("APP_VARIANT", appVariants);
if (onlyTestDevices)
whereCondition += " AND TEST_DEVICE = 1 ";
}
String orderByConditionStr = "";
if (orderByCondition != null)
orderByConditionStr = " ORDER BY " + orderByCondition;
String selectStmt = "SELECT GCM_ID, GCM_REGISTRATION_TIME, APP_NAME, APP_VARIANT, " +
"INSTALLATION_ID, DEVICE, LAST_UPDATE " +
"FROM GcmRegistration WHERE " + whereCondition + orderByConditionStr;
log.info("GcmIds Select: " + selectStmt);
ResultSet rs = null;
try {
long start = System.currentTimeMillis();
rs = dbConnection.createStatement().executeQuery(selectStmt);
log.info("Select duration: " + ((System.currentTimeMillis()-start)/1000) + " secs.");
int count = 0;
while (rs.next()) {
GcmRegistration reg = new GcmRegistration();
reg.gcmId = rs.getString(1);
reg.gcmRegistrationTime = rs.getLong(2);
reg.appName = rs.getString(3);
reg.appVariant = rs.getString(4);
reg.installationId = rs.getString(5);
reg.device = rs.getString(6);
reg.lastUpdate = rs.getLong(7);
processor.processGcmRegistration(reg);
count++;
}
log.info(count + " GcmRegistrations processed.");
} catch (Exception e) {
String errorMsg = "Selecting GCM_IDs from table GcmRegistration failed.";
log.log(Level.SEVERE, errorMsg, e);
throw new DbException(errorMsg, e);
} finally {
if (rs != null)
rs.close();
}
}
I always execute this method with the same parameters and receive usually about 152000 rows.
In rare cases (I guess 1 from 50) I receive only about 62000 rows without any exception! rs.next() returns false, although not all result rows are delivered.
For Google: Last time this happened was 8/22/14 23:20 (MEST)

Ado.net Update Command is successful but database is not updated

The following code executes successfully and the return value of cmd.ExecuteNonQuery returns 1 indicating the row was successfully updated but the database is not truly updated. How could that be? I'm using sqlserver2008.
public string updatePost(string id, string head, string body)
{
connection = new SqlConnection(connString);
string cmdStr = "update News set Header = '"+head+"' , [Text] = '"+body+"' where Id = "+int.Parse(id)+"";
string msg = String.Empty;
try
{
connection.Open();
SqlCommand cmd = new SqlCommand(cmdStr, connection);
int effected = cmd.ExecuteNonQuery();
msg += "The 'News Post - id:"+id+"' was successfully updated. Rows effected:"+effected+"";
}
catch (Exception ex)
{
msg = "The attempt to update the 'News Post - id'" + id + " failed with message: " + ex.Message;
}
finally
{
connection.Close();
}
return msg;
}
Try this, this fixes some problems (like sql-injection), perhaps also your update issue:
public string UpdatePost(string id, string head, string body)
