Mar 19, 2014I 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.

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?

Jan 6, 2012In 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!!

Java Database - Inserting Value By User
Apr 25, 2014So 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");

Adding Record To A Database With Java
Jul 18, 2014I 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.
Dynamic SQL In Java - Query Value From Database
Jun 18, 2014I 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 ....
