I am new to java and attempting to write a method that will insert data from a cachedrowset into an MS Access 2010 database table. My goal is to use this code that will accept any kind of Oracle SQL table size with different kinds of values and insert them into MS Access.
After I ran the code I get an error message below. By process of elimination i was able to find the issue is coming from the method called "insertAccessTable" somewhere in the while loop area "while (CRS_insertAccess.next())", but I am stumped on how to resolve this issue.
java.sql.SQLException: Parameter-Set has missing values.
Below is my Oracle SQL test table that I used for this exercise.
create table book (
TITLE_ID CHAR(3 BYTE)
TITLE_NAME VARCHAR2(40 BYTE)
TYPE VARCHAR2(10 BYTE)
PUB_ID CHAR(3 BYTE)
I need my java program to insert data into my access database. I get no errors in my code, but it never inserts, deletes the data in my database. Here is my code:
import java.awt.*; import java.awt.event.*; import java.sql.*; public class INS extends Frame implements ActionListener{ Frame f; Label l1, l2; TextField t1, t2; Button b1, b2, b3, b4, b5; Connection c;
I am reading from a database(SQL Server 2012) and storing that information in a ResultSet. I am then trying to display that information using a DataTable.
Here is my managed bean
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ package clientspage; import java.io.Serializable;
[Code].....
The ID and the commandLinks are being displayed but the Client is not.
I am using CachedRowSet returning it from a parameterised select statement and it works fine.
If I put the same select statement into a simple read-only stored procedure then I get this exception: "A result set was generated for update".
I am not trying to update the rowset in my code.
I tried to make the CachedRowSet to be read-only but it does not work, same error.
Question 1 : can a stored procedure returning a single result-set be called to populate a read-only CachedRowSet? (in a similar fashion to a CallableStatement prepareCall method with input/output parameters).
Question 2: in general is using CachedRowSet, WebRowSet, FilteredRowSet (disconnected) and JDBCRowSet (connected) something to be encouraged for future develpment or are they deprecated, or replaced by something else/better??
I don't really get the concept of how I "insert" an item into an array. I get a cannot find symbol error when I try to. I think its because I'm losing focus. What sort of code would "insert" an item into an array? I just want a goal of conceptually how I would do it.
Anyways, here are the instructions for the exercise:
Write a new class method, insert, for the Item class that takes three arguments - an Item[] array, an Item newItem, and an int k - and inserts newItem into array at index k, discarding the last item of the array (that is, the item originally at index array.length - 1).
Here is the uneditable code:
public class Item { private int myN; public Item( int n ) { myN = n; } public String toString()
[Code] ....
I get a cannot find symbol error, but I thought I was doing as I was supposed to. I thought you had to have an ArrayList to be able to insert or delete an item from an array. How can you take a primitive object, like an array, and insert something into it. My idea of it was a[i] would be replaced with a[i + 1]. I know I'm getting this concept wrong because that's what I tried to do.
We have this piece of code and we must make a search for a key. if the key exist it returns true if not false. Plus we must insert a key in the class. If it is already in there we say hey its already in and we don t put it again...
package askisi2; import java.util.*; public class mtree { protected class tnode { public int k1; public int k2; public int k3;
i found some problem for this jsp code. Actually I'm new in jsp. I'm trying to insert some data in a sql table in jsp by user input. Here's my code but i couldn't completed it.

My task is to implement a B-Tree data structure in Java using no libraries.
My current problem is inserting when the root is full, thus the middle key goes to root.keys[0] and then it get the left and right side which are new Nodes separating and inserting their keys. My problem is that for some reason there is a random second number when in the root and secondly my boolean leaf is always false meaning it never detects that the Tree is deeper than root.
The coding makes sense to me and I have tried printing everywhere but still can't seem to find the problem.
public class BTree { /* 1. You may not modify the public interface of this class. You may however add any additional methods and/or field which you may require to aid you in the completion of this assignment.
2. You will have to design and implement a Node class. The BTree should house Integer objects.
3. You will notice that there are some overloaded methods, some of which work for Integer objects and some with primitive type int. You have to find a way to implement the methods to work with both types. */
class BTreeNode { boolean leaf = true; int numKeys = 1; int mOrder; Integer keys[];
I am creating a portal using JSP and MySQL with eclipse IDE. I have a scenario where data is stored on draft table and is retrieved then stored on another table. I need the entry in the draft table to be deleted after the insertion. When I tried to run the code it redirects to success page but makes no impact on database(neither inserts not gets deleted).
I am trying to add a while loop into my switch statement. If you run the program, it will ask to enter the class grade (9,10,11, or 12). If you insert 5, it will say to try again. But, if you enter a wrong number twice, it will continue on to the next part of the program, which is asking how many students are in the class. Therefore, I believe a while loop would work, but it is not working at all. The program still runs, just doesn't fix the error. The program is below:
import java.util.Scanner; public class stephProject { public static void main(String[] args) { //call method welcomeMessage(); //method 1 of 3
List item List item List item List item List item List item List item
I want to insert the above text in the same way as it looks above in jtextpane. I would be copying it from word and inserting it in jtextpane. When I copy the text in jtextpane the bullets disappear. Also i dont want to use HTMLEditorKit.
I can insert data to table by using JSP Scriptlet easily but I have a hard time with servlet.
public class UsertToDatabase() { public boolean inserUser(String name, String email, String pwd) throws SQLException { PreparedStatement pstmt = null; boolean flag = false; System.out.println("start"); openConn(); System.out.println("start_1"); if(conn == null) {
[code]....
I am positive that the above code function fine. The problem is whenever I call UserToDB() class inside the servlet, and I got this error: java.lang.ClassNotFoundException: org.postgresql.
Driver which mean that my conn (connection) is not connected to the database but I have ensure to do so by calling openConn() before start the transaction.
public static void getInput(int [] student, int []test1,int []test2,int []test3, int [] test4, int [] test5) { int stuId = 0; int t1 = 0; int t2 = 0; int t3 = 0; int t4 = 0; int t5 = 0; int h = 0; char answer = '@';
I need to read in a file then create the tables and load in the data from the files to the database. I cant seem to figure out how to load the provided text file into the database.it contains lines like this
Boston Americans,AL,Pittsburgh Pirates New York Giants,NL,Philadelphia Athletics etc..
The first line in the field is the name of the team that won in 1903, and the last line is the name of the team that won in 2013. Note that the World Series was not played in 1904 or 1994, so those years are skipped in the file
The program should have a menu that has the following options.
NOTE: the data for choices to e) needs to come from running sql statements on the database tables created in choice a). Not from an ArrayList in memory.
a) Convert the baseball text file to a database table. Ask the user from a dialog box, for the location of the text file. This menu item should create the tables and load up the data.
b)Let the user input a team name, and list all of the years that they won the World Series
c)Let the user input a team name, and list the number of times they won the World Series
d)Let the user input a year, and you list the winner and loser for that year.
e)Add a new winner. The user should supply the winning team name, losing team name and year. Make certain that the year does not yet exist in the table and do not duplicate the team name(s) if they are already in the database tables.
f)Exit
I have two tables teams and games:
Drop table if exists game; Drop table if exists team; CREATE TABLE IF NOT EXISTS game ( yearGame int(11) NOT NULL, winTeam int(11) NOT NULL, lossTeam int(11) NOT NULL,
[Code] ....
I cant figure out how to load the values into the tables as only some of the fields are in the text and and the league field is in a seperate table. Here is my script so far
do { JFileChooser chooser = new JFileChooser(); FileNameExtensionFilter filter = new FileNameExtensionFilter("Text/Java files", "txt", "java"); chooser.setFileFilter(filter); int returnVal = chooser.showOpenDialog(null);
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 have tried this code to insert into datbase if not exists but i get an Exception in thread "main" com.mysql.jdbc. exceptions.jdbc4.
