I want to make a database and use it in my java program. I am thinking of using MS Access database, although I m not very sure, sine I will have to use this data later in the SQL database as part of C# program.
How to start to create and use MS database in java program.
I have seen in one tutorial that the steps are:
1. Install your database management system (DBMS) if needed
2.Install a JDBC driver from the vendor of your database
but I am not familiar with this. Any example, or is this above compulsory?

In MVC, M is the model, V is the view and C is the controller. But whatever projects I have made till now, I have a separate layer called data layer where I do all the database operations. In MVC, are we saying that the database operations are within the controller layer? That's quite a little mismatch! Separation of layers yet merge of controller & database operations!!

I would like to make a database using HTML and Java. I already made something like this using swing. I am just looking for some pointers here. I just started looking into Java Play 2 and I have a feeling this is what I am looking for. JavaEE is very complicated and I have read that it is being phased out. What is your opinion on this?
I want to make a static HTML page and put it on my home network and treat one of my computers as the sever accessing mySQL.

So I am working on a DB homework assignment and I am confused in how to implement a users input into the DB; I have to enter some values into a Table that is filled out by a user. It is a basic program, no GUI needed at this point.
I have written the main part but I don't know how I would get the typed value of the data into the SQL Insert Query.
Here is my code (I have a working Database and table with Java DB)
public class AddPeople
{
public static void main(String[] args)throws Exception
{
Scanner kb = new Scanner(System.in);
try
{
Connection conn = DriverManager.getConnection("jdbc:derby:PeopleDB");

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.

I have code which query value from database, the use case is the user can enter value as 1,01,11 in database but when the user enter value in xml file he can only enter 11,01,12 in database there is two columns lets say column test1=1 and test2=2 combination of this is 12, which is the value the use will enter in xml, but sometime the use can enter test1=04 than column test2=00 how can i approach this
I got table called card with column crdind,crdpos1,cardpos2 as primary key. The user can enter value as
crdind=1
crdpos1=5
crdpos2=3
inactivedate=2013-05-24
activedate=null
another row
crdind=1
crdpos1=5
crdpos2=5
inactivedate=2013-05-24
activedate=null
another row
crdind=6
crdpos1=02
crdpos2=00
inactivedate=2013-05-24
activedate=null
The rule say if you enter one number in crdpos1 eg 2 than you must enter value in crdpos2 it can be any number 1-9 but if you enter 00-09 in crdpos1 than crdpos2 is 00
The challenge I have is to query this value after they been enter. I have xml file which got field crdpos the use enter 15 which is the combination of column crdpos1=1 and crdpos2=5 ... How can I split the value crdpos and got and able to query in database in two separate column ....

I have a shop and I use visual studio.net to create an Inventory application to manage my shop. So I am familiar with vb.net codes.
Now, I'm trying to built another Inventory application for my shop using java, 'coz now I'm using Linux Ubuntu for my OS desktop and there's no visual studio.net in linux.
So in vb.net, there's a module that I use for database connection that I can call from any form that I needed.
I searched google for the equivalent module for java and there is none. But, there's an example that use a new java class.
Here's the code in MySQLConnect.java :
Java Code:
public class MySQLConnect {
static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
static final String DB_URL = "jdbc:mysql://localhost/dbInventory";
static final String USER = "root";
static final String PASS = "root";
public static Connection ConnectDb() {

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 to store data I've pulled from the web i wanted to do this by storing it in a database but after looking at some tutorials i'm not sure if its possible as the databases don't seem to run with the application but instead run as an independent entity.if its possible to have a database in the java application so it runs when the application runs.

I am new to Java Stored Procedures. There is a PL/SQL package in our legacy application(Oracle 9i) which pulls data from Oracle 8i source database through a DB link. Now we have upgraded our databas to Oracle 11g R2 from 9i. So the DB lint to Oracle 8i will no longer work in 11g. Hence I have created a Java stored procedure that establishes JDBC thin connection to the source 8i database. I have loaded the java stored procedure in the database using loadjava and have created a call specifaction.
I have called this java stored procedure inside the PL/SQL package. Now while executing the PL/SQL package, it takes the default driver ojdbc6.jar to establish JDBC connection and fails to connect to the 8i database giving ArrayIndexOutOfBounds Exception. While running the code in the linux application server with classes12.jar the code succeeds. But when the same is called in the database it fails.
1. How can I make my PL/SQL call use classes12.jar while calling the Java Stored Procedure?
2. How can I load the jar file(which includes my classes and the classes12.jar) into the datase as one object? (When I tried to load the whole jar, in database the classes and dependent jar loaded separately)
3. Is there a way to use classpath while calling the Java Stored Procedure like how we do from Unix?

I am developing my first Java application and the database I use is MySQL. I have created two separate buttons; one to insert new data into my database and the other to update the database when changes are made.
Each button is working perfectly, but I now want to combine both functions into just the save button. Thus, whether I am entering new data or modifying existing data, the save button should use an IF ELSE condition to decide whether to use the INSERT or UPDATE command.
My problem is, how do I write this IF ELSE statement? What should be the condition? For example;
IF(what? ){
String sql ="Insert into Table1 (classID,className,counselorID,startDate,endDate) values (?,?,?,?,?)";
}ELSE{
String sql2 = "update Table1 set classID = '"+value1+"',className='"+value2+"',counselorID='"+value3+"',startDate='"+value4+"',endDate='"+value5+"'
where classID = '"+value1+"'";
}
