Insert A Record To A Table In Database - SQLITE Syntax Error
Jul 19, 2014
I am trying to insert a record to a table in my database . I used the same syntax for 2 tables, one does work and the other does not work . I could not find any explanation for this error
"INSERT INTO CustomerRecord (Name, Number, Adress)"
+" VALUES(?,?,?)"; //first table working well
ps.setString(1,r.getCustomerName());
ps.setString(2,r.getCustomerNumber());
[Code] ....
For some reason one does work but the other does not work it says syntax error near order (table name). I am using sqlite db ...

I was asked to create an Android App with SQLite Database. I had referred some example and tutorial which can be found from the internet but 1 thing that is still unsolved.
The default path for Android SQLite is //data/data/<Your-Application-Package-Name>/databases/<your-database-name> which can be found in Eclipse DDMS after connecting the phone to the computer or the emulator is on.
I had tried many example and tutorial and yet I can only access to "data" file only and the rest (/data/<Your-Application-Package-Name>/databases/<your-database-name>)are never appeared on my screen. This is one of the website (URL....) I learnt to create my database app.
I had follow the steps exactly for many times but I still can't find the path. The app is running fine as it will show saved data/"contact" although I restart the apps(Which mean it did save my data but I just can't find where did it saved). What's wrong with my Eclipse?

I have java application used to manage a sqlite database (add new records, search .....) I already have everything and I convert it to jar file but the question is how to burn it to cd with the sqlite database . I mean we need to change the database URL for connection class. My question is there any programs would combine my database + my jar file and make it exe file ?
or i should manually change my database url in connection class ? (if yes what should i write knowing that my database and my jar file will be burnt to a cd). I searched online but i could not found any one related sqlite database or at least a clear one . I already has my jar file but if i moved the database from its directory it will not work ...

I have a superclass used for all the other entity
@MappedSuperclass
public abstract class BssStandardEntityLaravel extends BssStandardEntity
implements InterfacciaBssStandardEntity, Cloneable{
private static final long serialVersionUID = 1L;
@Column(name = "created_at", nullable=true)
@Temporal(TemporalType.TIMESTAMP)
protected Date created_at = new Date();
[Code] ....
When i try to read some data with a JPA controller, this error is raised:
Persistent class "com.bss.libbssabstract.database.entity.BssStandardEntityLaravel" has no table in the database, but the operation requires it. Please check the specification of the MetaData for this class.
org.datanucleus.store.rdbms.exceptions.NoTableManagedException: Persistent class "com.bss.libbssabstract.database.entity.BssStandardEntityLaravel" has no table in the database, but the operation requires it. Please check the specification of the MetaData for this class.
at org.datanucleus.store.rdbms.RDBMSStoreManager.getDatastoreClass(RDBMSStoreManager.java:702)
[Code] ....
It requires BssStandardEntityLaravel table like a normal entity. I used the same entity package in other applications and it works perfectly. Why this error is raised?
I use jpa2.1.0 and datanucleus to enhance classes

In my java web jsf seam jboss application, I want to add a row in a table with some data fields such as date type, String etc, but one field will be a word attachment, how to do it?
Basically, there is a loop to create some rows of data in a table, before each table row data creation, I will create a word file and saved to a local path(the physical file path is hardcoded), then I will create a table row and attach this word file to that row. the loop will continue until the end of loop.

I'm trying to execute SQLite query like this:
final String gender = new String();
if (sexCombo.getValue().toString().equals("Man")) {
gender = "1";
}
else {
gender = "0";
}
final string Q = "INSERT INTO ... VALUES (...., " + gender + "...)");
stmt.executeUpdate(Q);
The problem is:
error: local variables referenced from a lambda expression must be final or effectively final stmt.executeUpdate(Q);
How can I generate query command using conditionals and make it work?

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String delete = ("DELETE FROM anagrafica WHERE Nome = ? And Cognome = ?");
ConnectionManager cm = new ConnectionManager();
String Nome = request.getParameter("nome");
String Cognome = request.getParameter("cognome");
[code]....
and this is my JSP.The problem is easy, when I click on the grid for deleting the record two things happen, or the record is deleted only on JSP but not in my Database or Nothing happens even on my JSP, it is because I don't know how to get values from my jsp and send them to replace the ? in my delete query I tried even to give a name to the <tr> which contains Name and Last name but obviously i guess it works only for input type ex. Textbox.

I have a sqlite database i already have the connection with java and it works ... I have a method to add a record ...
public boolean AddRecord(CustomerRecord r){
String sql = "INSERT INTO CustomerRecord (Name, Number, Adress)"
+" VALUES(?,?,?)";
try {Connection connection = getConnection(); // call connection method
connection.setAutoCommit(false);
[Code] .....
I call this method in my interface and i write
if (addrecord == true){System.out.printnl("record added");}
I close the interface then enter search for the record i just added using add record method but i do not find it
what i am trying to say the added record using my application is not there. The question is how to save this record in the database ...
I thought
ps.executeUpdate();
should do this but it is not saved.

This is what i have so far, I use BlueJay to write this:
import javax.swing.JOptionPane;
public class payroll
{
String again = y;
//
private String name;
private double rate;
private double hours;
static double gross; //gross pay
[code]....
my first problem is that it expects a ")" on this line :"if ((hours <=40)rate *1);"For the assignment itself these are the requirements:
-Create a class called payroll with private variables for rate hours and name
-Create static variables for gross pay, union dues, health coverage (hp in my case), FICA taxes, State taxes, Federal taxes, net pay, all must be initialized to 0
-default constructor that assigns default values
a function called calcPay that will do the following tasks and print it to a pay stub :
- function that checks the hours ( if hours are 40 or less pay rate, if over 40 pay 150% of the rate)
- calculates gross pay before any deductions (using user inputted hours and rate)
- deduct medical coverage and union dues from gross pay and call this adjusted gross pay (also this should have its own line on the paystub)
- A function that deducts State, federal and fica taxes from adjusted gross
- FICA - 7% for any income
-Federal - 2% for $0-$150 / 6% for 150.01 - 300 / 14% for 300.01 - 600 / 18% for 600.01 - unlimited
-State - 1% for 0-150/ 3% 150.01 - 300 / 5% 300.01 - 600/ 8% 600.01 - unlimited
- amount after all deductions is the net pay ( show this amount on its own line)
- Start a loop that asks each time if there are more employees (y/n) y should continue the program and n should end it
-dialog boxes should be created to recieve values for name, hours and rate
- if the rate is entered below $8 dollars a new box should pop up and ask for a higher value
- When there are no more employees, print out a summary of quantities stored in static variable (also had a problem with this)
- End
So I think i completed most of these objectives but am having trouble with the syntax and some of the objectives

So my only error in the entire code is on the 9th line of this code sample. It says "Syntax Error on token "new", @ expected" but @ does not belong there, as far as I can tell, since the error does not go away upon adding it.
public class Obstapacalypse implements KeyListener, ActionListener {
private static final String EXIT_ON_CLOSE = null;
private JFrame frame;
private Player player = new Player();
private JPanel contentPane;
private JButton btnStart;

I am facing the following scenario:
1- Take information from distinct columns from two different tables - OK
2- Insert this information into a new table.
I have created a ArrayList and inserted all the information that I need but now I am trying to put this ArrayList into the new table and I am not sure how to do it. I have done research and tests but unsuccessfully.

I'm not sure why I'm getting these errors. They only begin to happen after the second if statement, and the subsequent if statements are formatted exactly the same.
The errors are marked by the comments in the code.
Java Code:

public class GazillionSongs {
public static void main(String[] args) throws FileNotFoundException {
System.out.println("Welcome to Java Song Collection!");
System.out
