Question

I have a method like this:

protected long put(String tableName, ContentValues values) {
     SQLiteDatabase db = (!mInTransaction) ? mHelper.getWritableDatabase() : mDb;
     long success = db.insert(tableName, null, values);
     return success;
}

This method return -1 but data inserted into database. I checked my data, it’s ok. Anybody can help me 🙁

This is my table:

CREATE TABLE choices ( category_no INTEGER NOT NULL, subcategory_no INTEGER NOT NULL, quiz_no INTEGER NOT NULL, choice_no INTEGER NOT NULL, answer TEXT NOT NULL, content_id INTEGER NOT NULL, PRIMARY KEY ( category_no, quiz_no, choice_no ) );

Answer 1

-1 is returned if error occurred. .insert(...) returns the row id of the new inserted record. Is this important? Do you have _id field in your db?
