Record set in java

Dear Sir,
I found java tutorial so much interesting & informative .I have switch my data base programming from Microfoft Visual basic 6 to Java to make plateform independent database application .
I want to make a database application where i can move to next record set by pressing a button & also move back to see my previous recordset by using JButton.
In other language just like Visual Basic a programmer can easily do it but i do,t know how can i do same thing in SDK java2.
Sir is it possible in java database application ?
Hope soon for the reply,
Thank you,
Ali

The key is to tell the driver to use a specific type of Statement object, in particular ...TYPE_SCROLL_SENSITIVE ie:
Statement stmnt = con.createStatement(
java.sql.ResultSet.TYPE_SCROLL_SENSITIVE,
java.sql.ResultSet.CONCUR_UPDATABLE
); Then, after creating a result set from this statement, you can use the previous and next commands, as well as absolute row commands found in the ResultSet object.
However, these will not work if you do not explicitly create the special type of Statement object ie. this won't work:
Statement stmnt = con.createStatement(); Hope this helps. Not all drivers will support this.

Using a session object to hold the value of a record set?

Hi,
I'm trying to hold the value of a record set (or literally the content of a column in a query in a db) in a session variable so that I can call on this later and insert into another table.
I'm not sure of the correct syntax, I've already made a connection to the DB. I'm trying the following but it doesnt seem to like the code:
<% session.setAttribute("code",rs("column_name")); %>
<%String attrib =
String.valueOf ( session.getAttribute("code")); %>
Hello <%= attrib %>
Any ideas, I dont know how to reference the record set, I declared the recordset previously as rs. Help! Can't find examples anywhere on the net!

So just to recap. I appear to be seeing the column name "custorderno" within the Microsoft Access query "lastcust". But I get "no data found" when I run the following code (which I have sectioned off)
<!-- connect to database and lastcust query --!>
<%
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
Connection conn = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=C:/Tomcat/jakarta-tomcat-4.1.31/webapps/ROOT/Oatcake.mdb","","");
Statement statement = conn.createStatement();
String sql = "SELECT * FROM lastcust";
ResultSet rs = statement.executeQuery(sql);
while (rs.next()) {
%>
<TR><TD><%= rs.getString("custorderno") %></TD>
</TR>
<% session.setAttribute("code",rs.getString("custorderno")); %>
<% String attrib =
String.valueOf ( session.getAttribute("code") ); %>
Hello <%= attrib %> [B]
<%
%>
</TABLE>
<%
if (statement != null)
statement.close();
if (conn != null)
conn.close();
catch (Exception e) {out.print(e);}
%>
</BODY>
</HTML>
No as mentioned I am (as you can see) declaring everything as a string when in actual fact the contents of the "custorderno" within the query is set to a autonumber within MS Access.
The while loop does work by returning the contents but the session object part is not working correctly with the following result returned:
[B]java.sql.SQLException: No Data Found
Help please!

I had a generic record class that has a HashMap to hold the data fields (...)
method called createRecord() for each record type which would populate the HashMap with the correct data fieldsI'm not sure I understand: are the contents of this field map the same between two records of the same type? Then yes, you don't need to clone the map per record instance.
one thing that needs fixing is the fact that each time the createRecord() method is called I'm creating a new fieldMap to define the dataFields in the record class.Probably, but that will only get you a little bigger files; you won't gain an order of magnitude on the size of files. The problem for huge files is that as soon as their content is bigger than the available memory, you'll run into problems. A more radical approach if you need to address huge files is to process the records on the fly, and not load all records in memory. Of course not all algorithms or business logic can afford that...
I know I could rewrite the code and create a class for each record type and declare the fieldMap static but I was wondering if anyone had any better suggestions The Record instance could receive and keep a reference to its RecordType instance, and ask the RecordType instance the DataType for a field's name. That way the RecordType encapsulates the map, and there's less risk that a clumsy other class modifies the static map.
before I go rewriting a load of code.A load of code?!? Even with the idea of the static map, you only have to edit the enum type (well more accurately, each RecordType enumerated constant's createRecord() method).

Recording a thick java client app

Can eTester record a thick java client application? I've tried using proxy but that doesn't appear to work.

James
eTester can record thick client app HTTP requests, you should use:
A external proxy recorder:
- Options -> Current Script -> Recording -> Proxy and select record navigations in a external application.
- Remove the ;application/* from the exclude statement
- Set the proxy of the thick Java app to point to, localhost on port 7777
If the thick java app is a Java Applet you will need to set the JVM to point to the porxy at locahost 7777 to do so:
- Start -> Control Panel -> Double click on Java -> under the general tab select network settings, select use proxy server and enter the proxy settings.
Happy recording !!!!

By which method,i can get the no of rows in the record set?

Does anyone help me that by which method,i can get the no of rows in the record set?
now i use next() to check whether the next record is available or not?

under Practice Exercise #1 heading :
there is a statement.
"Now, the COUNT function does not need to retrieve all of the fields from the table (ie: employee_number, employee_name, and salary), but rather whenever the condition is met, it will retrieve the numeric value of 1. Thus, increasing the performance of the SQL statement."And have you ever tried it? Or do you simply blindly believe everything you read? And what sort of "authority" is "tech on the net"?
P.S. A quick test on Oracle (and you must do each query at least twice throwing away the first result, as Oracle always caches things which will have an effect, and averaging the remaining attempts).
count(*) -- 1 min 17 secs for 35,311,978 rows
count(1) -- 1 min 19 secs for 35,311,978 rows
Edit: And the table has 46 columns.

File content conversion record set per message

Dear All,
Problem:- File is of huge size because of which file content conversion is taking longer time and is failing.
File format:-
Header
Detail
Detail
Header
Detail
Detail
Detail
Detail
Header
Detail
Detail
Trailer
Trailer has total count of all detail record,header record and there are few checks as well as wrt other fields.
We need to do all the above validation on the file and if it successful it shud process it otherwise alert shud be raised.
As a step:-
I have used record set per message for splitting up the file because of huge size this functionality is working fine but because of spitting of file i am not able to do trailer validation as XI is creating multiple records with different message ID's
Is any other approch which will help to achieve both Spliting as well as validation
chirag

Chirag,
simplest scenario I can think of is splitting the 2 reqs.
1. create 2 folders, one for "in process" files and other for "validated" files.
2. create 2 scenarios:
2.1. your current sender system to in process folder (whatever to File).
=> In this you just do the validation, without FCC. You could create a simple module for that or even do it at mapping runtime, as you said (mapping may be easier to handle errors), and throw a runtime exception (which will eventually trigger an alert).
=> At the end, only files that go successfully throug the validation will be located in the "In Process" folder.
2.2. do a simple file to file scenario (from "In Process" to "Validated" folder), this time executing FCC & splitting messages if necessary.
Of course, this will only work if the module/mapping is able to process the large file anyway (hopefully yes, since it will still be a flat file and not XML yet).
BR,
Henrique.

How to put record set in loop

Using the follwing query
select distinct code from oalr where code > '" & AlertCode & "' and code<=('" & code & "') "
i got 5 records eg :5603,5604,5605,5606,5607
record set fetching
Ocode = CStr(rs4.Fields.Item(0).Value)
Here Ocode get only last record eg :5607, i want to take this 5 records in the loop how can i write the coding

Thank for ur reply,
But i not passing this in to matrix , i m going to pass the value in to anothe record set
eg
Ocode = CStr(rs4.Fields.Item(0).Value)
select A.code,A.MsgData,B.UserSign,C.Portnum as MobileNum from OALR A inner join ALT1 B on A.Tcode=B.code inner join OUSR c on C.UserID=B.UserSign where A.code='" & Trim(Ocode) & "' ")
I want to pass the Ocode value in to the loop.becoz only one value pass this query next time pass means duplicate value prob occure so i want to pass the Ocode value up to EOF. Give some solution

Read only record sets ?

We're using a function to return a ref cursor back to VB.
Works great until we try and update it. As soon as we try and update the record set we're getting an error "Multi-step operation generated errors. ". It looks to us like the record set is read-only. We've tried using an in-out parameter to a procedure - same problem. However, it works fine as long as we pass the sql instead of a call to a function or procedure.
We don't really want to have to pass the sql.
Can anyone help with this ?
Thanks,
Tricia.

Ref cursors that are returned to an application from a stored procedure are read-only if you're using ODBC or OLE DB. I believe that the beta .NET native provider will allow you to update returned ref cursors, however.
The reason it works when you issue straight SQL is that the driver actually modifies your SQL statement to get the ROWID's for all the rows. Then, it's able to update rows by building its own SQL insert statement.

Can we enable "Select record Set Message choice" of Table in left side

Hi ,
I have requirement to set the "Select Record Set " Message choice of a table region on left side.
Ex:If there are more records in a table region and message choice available to select next set of records.
You can chk in Workflow Status Monitor function.
Its the Navigation Bar to be @ left side on the table Region whcih allows you to navigate the records set.
Thanks,Sarath.
Edited by: SarathL on Dec 13, 2011 4:59 PM

Hi,
Not sure what exactly you are looking for.
The Next link and option to select next set of rows comes to your OA Table by default .. isn't it?
