Hi I'm making a bill splitting app in android studio 3.3. I've made a database with sqlite and it stores a product's name and cost. As I am trying to get the total cost of the input from the database and store it in a text view the app closes. I've came to the conclusion that the problem is located in the getTotal() method in MyDBHandler.java
public class MyDBHandler extends SQLiteOpenHelper{
private static final int DATABASE_VERSION = 6;
private static final String DATABASE_NAME = "productDB.db";
public static final String TABLE_PRODUCTS = "products";
public static final String COLUMN_ID = "_id";
public static final String COLUMN_PRODUCTNAME = "productname";
public static final String COLUMN_PRODUCTCOST = "productcost";
//We need to pass database information along to superclass
public MyDBHandler(Context context, String name,
SQLiteDatabase.CursorFactory factory, int version) {
super(context, DATABASE_NAME, factory, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
String query = "CREATE TABLE " + TABLE_PRODUCTS + "(" +
COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
COLUMN_PRODUCTNAME + " TEXT " + "," +
COLUMN_PRODUCTCOST + " INTEGER " +
");";
db.execSQL(query);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + TABLE_PRODUCTS);
onCreate(db);
}
//Add a new row to the database
public void addProduct(Products product){
ContentValues values = new ContentValues();
values.put(COLUMN_PRODUCTNAME, product.get_productname());
values.put(COLUMN_PRODUCTCOST, product.get_productcost());
SQLiteDatabase db = getWritableDatabase();
db.insert(TABLE_PRODUCTS, null, values);
db.close();
}
//Delete a product from the database
public void deleteProduct(String productName){
SQLiteDatabase db = getWritableDatabase();
db.execSQL("DELETE FROM " + TABLE_PRODUCTS + " WHERE " +
COLUMN_PRODUCTNAME + "=\"" + productName + "\";");
}
//get the total sum of teh Product_Cost column
//
// TODO: fix this method to display total
// NOTE: THIS IS YOUR PROBLEM
//
//
public int GetTotal(){
int temp;
SQLiteDatabase db = getWritableDatabase();
String query = " SELECT SUM(COLUMN_PRODUCTCOST) FROM " + TABLE_PRODUCTS + ";";
Cursor cursor = db.rawQuery(query , null);
if (cursor.moveToFirst()) {
temp = cursor.getInt(0);
}
else return 0;
cursor.close();
return temp;
}
// converts the elements in the database to a string so you can print the database out.
public String databaseToString(){
String dbString = "";
SQLiteDatabase db = getWritableDatabase();
String query = "SELECT * FROM " + TABLE_PRODUCTS + " WHERE 1";// why not leave out the WHERE clause?
//Cursor points to a location in your results
Cursor recordSet = db.rawQuery(query, null);
//Move to the first row in your results
recordSet.moveToFirst();
//Position after the last row means the end of the results
while (!recordSet.isAfterLast()) {
// null could happen if we used our empty constructor
if (recordSet.getString(recordSet.getColumnIndex("productname")) != null) {
dbString += recordSet.getString(recordSet.getColumnIndex("productname"));
dbString += "\t $";
dbString += recordSet.getString(recordSet.getColumnIndex("productcost"));
dbString += "\n";
}
recordSet.moveToNext();
}
db.close();
return dbString;
}
}
public class MainActivity extends AppCompatActivity {
EditText userInput;
EditText userInputC;

You should change :-
String query = " SELECT SUM(COLUMN_PRODUCTCOST) FROM " + TABLE_PRODUCTS + ";";
to be
String query = " SELECT SUM(" + COLUMN_PRODUCTCOST + ") FROM " + TABLE_PRODUCTS + ";";
Otherwise the query will fail as there is no column named COLUMN_PRODUCTCOST, instead you want the value when COLUMN_PRODUCTCOST is resolved (i.e. productcost), which is a column name.
You may also wish to consider using the query convenience method rather than using the rawQuery method.
Your code could then be :-
public int GetTotal(){
int temp;
SQLiteDatabase db = getWritableDatabase();
String[] columns = new String[]{"SELECT SUM(" + COLUMN_PRODUCTCOST + ")"}
Cursor cursor = db.query(TABLE_PRODUCTS,columns,null,null,null,null,null);
if (cursor.moveToFirst()) {
temp = cursor.getInt(0);
}
else temp = 0; //<<<<<<<<<< CHANGED not to return as the Cursor would not be closed.
cursor.close();
return temp;
}
Note this closes the Cursor even if there are no rows, which should be the case (you could apply this to your code that uses rawQuery).

This is a bad sql query:
String query = " SELECT SUM(COLUMN_PRODUCTCOST) FROM " + TABLE_PRODUCTS + ";"
Should it be
String query = " SELECT SUM(" + COLUMN_PRODUCTCOST + ") FROM " + TABLE_PRODUCTS + ";"

android.database.CursorIndexOutOfBoundsException -- my cursor is empty

So I have been trying to query in my sqlite database for my android app. However, it seems like my cursor is not working like it is supposed too as I can get any results.
I know that I only have 3 items in my database, but what I put in my query are valid attributes for my 3 items stored. But there is still no result.
Below is my code for the query function and my database model.
// To get data from DB by querying the items selected
public String getData(int firstSelection, int secondSelection, int thirdSelection,
int fourthSelection, int fifthSelection)
{
SQLiteDatabase db = dbHelper.getWritableDatabase();

firstSelectionStr = Integer.toString(firstSelection);
secondSelectionStr = Integer.toString(secondSelection);
thirdSelectionStr = Integer.toString(thirdSelection);
fourthSelectionStr = Integer.toString(fourthSelection);
fifthSelectionStr = Integer.toString(fifthSelection);
//String[] columns = {DBHelper.UID,DBHelper.CNAME};
//Cursor cursor = db.query(DBHelper.TABLE_NAME,columns,null,null,null,null,null);
String selectQuery = "SELECT * FROM "+ DBHelper.TABLE_NAME + " WHERE " + DBHelper.FIRST_ATTRIBUTE + "=? "

i think your course return 0 item according to query..so you should write below condition
cursor.moveToFirst(); <--- instead of this
if(cursor.moveToFirst()){
// here all your code
}

Unable to make more than 2 columns in SQLite Android Eclipse?

Why is that when i have more than 3 columns the app crashes? I tried debugging it by commenting out one column and it runs perfectly. After debugging it some more I found out that the problem might be on the 'populateListview' because I was able to run the app but now it won't display anything. Why do you think I couldn't run it with more than 3 columns?
Here's my dbAdapter:
// Field Names:
public static final String KEY_ROWID = "_id";
public static final String KEY_INGREDIENTNAME = "ingredientname";
public static final String KEY_IMAGE = "image";
public static final String KEY_DETAILS = "details";
public static final String[] ALL_KEYS = new String[] {KEY_ROWID, KEY_INGREDIENTNAME, KEY_IMAGE, KEY_DETAILS};
// Column Numbers for each Field Name:
public static final int COL_ROWID = 0;
public static final int COL_INGREDIENTNAME = 1;
public static final int COL_IMAGE = 2;
public static final int COL_DETAILS = 3;
//SQL statement to create database
private static final String DATABASE_CREATE_SQL =
"CREATE TABLE " + DATABASE_TABLE
+ " (" + KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
+ KEY_INGREDIENTNAME + " TEXT NOT NULL, "
+ KEY_IMAGE + " TEXT"
+ KEY_DETAILS + " TEXT"
+ ");";
// Add a new set of values to be inserted into the database.
public long insertRow(String ingredientname, String image, String detailsValue) {
ContentValues initialValues = new ContentValues();
initialValues.put(KEY_INGREDIENTNAME, ingredientname);
initialValues.put(KEY_IMAGE, image);
initialValues.put(KEY_DETAILS, detailsValue);
// Insert the data into the database.
return db.insert(DATABASE_TABLE, null, initialValues);
}
// Return all data in the database.
public Cursor getAllRows() {
String where = null;
Cursor c = db.query(true, DATABASE_TABLE, ALL_KEYS, where, null, null, null, null, null);
if (c != null) {
c.moveToFirst();
}
return c;
}
Here's my populateListView Code:
private void populateListView() {
Cursor cursor = myDb.getAllRows();
String[] fromFieldNames = new String[] { //DBAdapter.KEY_ROWID,
DBAdapter.KEY_INGREDIENTNAME };
int[] toViewIDs = new int[] { //R.id.textViewItemNumber,
R.id.textViewItemTask };
SimpleCursorAdapter myCursorAdapter;
myCursorAdapter = new SimpleCursorAdapter(getBaseContext(),
R.layout.item_layout, cursor, fromFieldNames, toViewIDs, 0);
ListView myList = (ListView) findViewById(R.id.listViewTask);
myList.setAdapter(myCursorAdapter);
}

You miss a comma, here:
private static final String DATABASE_CREATE_SQL =
"CREATE TABLE " + DATABASE_TABLE
+ " (" + KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
+ KEY_INGREDIENTNAME + " TEXT NOT NULL, "
+ KEY_IMAGE + " TEXT"
+ KEY_DETAILS + " TEXT"
+ ");";
It should be
private static final String DATABASE_CREATE_SQL =
"CREATE TABLE " + DATABASE_TABLE
+ " (" + KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
+ KEY_INGREDIENTNAME + " TEXT NOT NULL, "
+ KEY_IMAGE + " TEXT,"
+ KEY_DETAILS + " TEXT"
+ ");";

Checking if row exists SQLite

I would like to check if any row exists within the Sqlite database.
my java class
public static final String DATABASE_TABLE2 = "receivernumber";
public static final String KEY_ROWID2 = "hpnumberID2";
public static final String KEY_NAME2 = "hpNumber2";
public long insertContact2(String hpNumber2)
{
ContentValues initialValues = new ContentValues();
initialValues.put(KEY_NAME2, hpNumber2);
if(CheckIsDataAlreadyInDBorNot(0) == true) {
return db.update(
DATABASE_TABLE2, initialValues, "SET='"+KEY_NAME2+"'" +"WHERE"+ "KEY_ROWID2="+1, null
) > 0;
}
else {
return db.insert(DATABASE_TABLE2, null, initialValues);
}
//if there is alrdy a record, create a method to reject intake
return 0;
}
public boolean CheckIsDataAlreadyInDBorNot(long hpnumberID) {
Cursor mCursor = db.query(
true, DATABASE_TABLE2, new String[] {KEY_ROWID, KEY_NAME},KEY_ROWID + "=" + hpnumberID, null, null, null, null, null
);
String Query = "Select * from " + DATABASE_TABLE2 + " where " + KEY_ROWID2 + " < " + 0;
SQLiteDatabase sqldb = EGLifeStyleApplication.sqLiteDatabase;
Cursor cursor = sqldb.rawQuery(Query, null);
if(cursor.getCount<=0) return false;
return true;
}
public boolean updateContact2(long hpnumberID2, String hpNumber2)
{
ContentValues args = new ContentValues();
args.put(KEY_NAME2, hpNumber2);
//args.put(KEY_NAME3, Selected);
//return db.update(DATABASE_TABLE2, args, KEY_ROWID2 + "=" + hpnumberID2, null) > 0;
//db.execSQL("UPDATE " + DATABASE_TABLE2 + " SET " + KEY_NAME2 + " WHERE " + KEY_ROWID2 + "=1 ");
return db.update(DATABASE_TABLE2, args, "SET='" + KEY_NAME2 + "'" + "WHERE" + "KEY_ROWID2=" + 1, null) > 0;
}
So my database layout is such that the user can only add a number for the first time. Subsequent times the user wishes to add a number, it would be replaced by an edit function instead. However, there's an error called EGLifeStyleApplication cannot be resolved to a variable. However, as this is an answer from questions solved successfully, they did not really explain what is the function of that EGLifeStyleApplications. So how do I go about doing what I want to achieve? (How do I edit my insert statement) Thanks.

Replace the offending line with
sqldb = ctx.openOrCreateDatabase(DB_NAME, Context.MODE_PRIVATE, null);
where ctx is a context you will pass as a parameter to your CheckIsDataAlreadyInDBorNot method. i.e.:
public boolean CheckIsDataAlreadyInDBorNot(Context ctx, long hpnumberID) {
and DB_NAME is a string containing your db name, i.e.:
private final static String DB_NAME = "rec_nums.db";
public static final String DATABASE_TABLE2 = "receivernumber";
public static final String KEY_ROWID2 = "hpnumberID2";
public static final String KEY_NAME2 = "hpNumber2";

SQLite two tables, one works, the other does not

I have an SQLite database in an Android app. One database with two tables. simple read in some text and read it out, however, the first of two tables works perfectly and the second table does not and gives errors. I have looked at my code and it seems all correct. I dare anyone to find an error in my code or SQL statements below.
Especially interested in the SQL statements, because my SQL code is PERFECT as far as I know, for both tables, however in the LOGCAT says that a there is no table that I am reading into for table two.
Why would one of my tables work and the other not? Yet they are in the same database and written the same way.
DATABASE OPERATION ON FIRST TABLE; (WORKS PERFECTLY)
ourHelper = new DbHelper(ourContext);
ourDatabase = ourHelper.getWritableDatabase();

}
return result;

<<< EDIT >>>
Safime's suggestion fixed the crashing, that was adding a space between KEY_DATE and TEXT in the creation of the second table.
However still a problem, no more crashing, but the insert() method is still not working. Getting a -1 return shows that it is not inserting anything, and the the table 2 is still empty after inserting a new row to the table. Got to find out why it is failing to create any new rows in the table. Just like earlier, table one works fine but table two is still not working yet.

You are using Constraint NOT NULL and you are inserting only in one column. You must be getting SQLiteConstraintexception Exception. Try inserting in all columns.

You are missing an empty space after the column KEY_DATE and before TEXT on the creation of the second table.
(...) + KEY_DATE + " TEXT NOT NULL); (...)

Probably you have a problem at the create table statement of your second table. Try to open your db file with the sqlite3 command line tool, and see if this table exits. If not, the problem is in the CREATE statement.
