Spring JDBCTemplate issue



i have a method to update multiple rows in my oracle database using jdbc template.
before updating the application has some processings to do, if these processings are successfully completed it goes on for the update.


HashMap<String, Object> mapUpdate = new HashMap<String, Object>();
mapUpdate.put("ID_REF_STATUT", IConstants.Status.GEN);
mapUpdate.put("DATE_REGLEMENT", new Date());
managerTransactionDao.updateListValeur(listValeurs, mapUpdate);

HashMap<String, Object> mapUpdateBord = new HashMap<String, Object>();
mapUpdateBord.put("ID_STATUS", IConstants.Status.GEN);
mapUpdateBord.put("DATE_GENERATION_DATA", new Date());
mapUpdateBord.put("NOM_FICHIER_DATA", file.getName());
managerTransactionDao.updateBordereau(vbordereau, mapUpdateBord);



below is the update method :


public int updateListValeur(List<VValeur> listValeurs, Map<String, Object> mapAttributForUpdate)

int result = 0;

if (listValeurs != null && !listValeurs.isEmpty())
String listIds = "";
for (VValeur vvaleur : listValeurs)
listIds = listIds + vvaleur.getIdValeur() + " ,";



if (listIds != null && !listIds.equals(""))
listIds = listIds.replace(",)", ")");
try
Object params = new Object[mapAttributForUpdate.size()];
String updateQuery = "UPDATE VALEUR SET ";
if (mapAttributForUpdate != null && !mapAttributForUpdate.isEmpty())
Iterator<Entry<String, Object>> it = mapAttributForUpdate.entrySet().iterator();
int i = 0;
while (it.hasNext())
Map.Entry attValue = (Map.Entry) it.next();
updateQuery = updateQuery + attValue.getKey().toString() + " =? ,";
params[i] = attValue.getValue();
i++;

updateQuery = updateQuery + "where ID_VALEUR in (" + listIds + ")";
updateQuery = updateQuery.replace(",w", "w");
updateQuery = updateQuery.replace(",)", ")");
result = jdbcTemplate.update(updateQuery, params);

catch (Exception e)
ExceptionUtil.log(e);



return result;



the update works fine on 99% of the cases but update failed on some cases even the query is logged to the log file but database values are not updated.





Code in image is a bad practice. Please add the code in question.

Never catch an exception. I'm assuming you are using Spring to manage your transactions and that might lead to an update getting lost or apparently trying to commit whereas it failed. If you are catching you should rethrow the exception.

@Aymen may be your where condition list values returned zero records for update. Have you checked list values against DB when the update failed.

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas...

Dynamically update html content plain JS

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12...

Creating a leaderboard in HTML/JS

Image
Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]...
