données ne pas insérer dans la base de données préconstruit

Question

Here is my project

Ici, je veux insérer quelque chose dans ma base de données. J'ai également utilisé this link comme référence mais cela va en vain.

Mais voici le journal des erreurs que j'ai.

Merci d'avance. Désolé pour le mauvais lien

Answer 1

public synchronized SQLiteDatabase getWritableDatabase() 

pas besoin de surcharger cette fonction. Utilisez simplement celui en construction.

En outre,

checkDB = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READWRITE); 

myDataBase = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READWRITE); 

changer les modes dans lesquels vous avez ouvert le DB à écrire.

Answer 2

données est inséré mais parce que deptID est la clé primaire, il donne l'erreur d'insérer des données en double dans le tableau Dept.

Answer 3

Ouvrez le DataBase comme suit

SqliteDatabase db=myDbHelper.getWritableDatabase(); 
ContentValues cv=new ContentValues(); 
cv.put(COLUMN_NAME,10); 
cv.put(COLUMN_NAME,"Kaushik"); 
cv.put(COLUMN_NAME,"dhor sala"); 
cv.put(COLUMN_NAME,22.332322332); 
cv.put(COLUMN_NAME,88.2323232); 
float row id=db.insert(TABLE_NAME,null,cv);
