GetString-problem

Hello!
Help, i need somebody...
I'm new in C++, VC and Oracle.
I use OCCI to connect on 10g db. Somehow i configured VC so now i can create .exe. I'm not sure that i can repeat configuration:).
In databes there is table whit only varchar2 fields. The problem is in this part of code:

string c2;
 while(rs->next())
{ counter++;
 for(int i=1; i<=5; i++) {
 c2=rs->getString(i);
 cout <<"row: "<<counter<<" field: "<<i<<" "<<c2<<endl; 
 }
 cout <<"******************"<<endl;
}

Nothing smart. But when getString gets something it fails( An unhandled win32 exception occurred in my.exe [3888] . When i reduce dataset only on fiedls whit "where length(varchar_field)<16" it never throw this exception. If i
Somethimes the program goes whitout any problem.
Please help!!!
I didn't find anything helpful on this forum.

which version of OCCI are you using? Can you try on the latest version (10.2 or 10.1.0.5)?

OCCI -getString problem

I'm having trouble executing code using the OCCI libraries. I suspect that it's an issue with the version of OCCI that I'm using but can't seem to resolve the problem myself.
On Windows 7, I'm using the OCCI libraries from the Oracle Express 11.2 32 bit install. I'm compiling in Eclipse Luna (for 32 bit) 1a using the CDT plugin. I'm using the compiler from Microsoft Visual Studio 12.0.
I'm using the oraocci.lib. (If I use the oraocci11d.lib, my code crashes just trying to make a database connection.) My current problem is with the oracle::occi::ResultSet::getString method. If I call it once on my ResultSet, it works fine. The second call causes my program to crash.
Here is my code:
std::sqlStr;
sqlStr = "SELECT START, END, BATCH_ID, AGENT_ID FROM AGENTS WHERE ID = :1";
connection code, stmt creation, etc
oracle::occi::ResultSet *rs = stmt->executeQuery();
if (rs->next()
   double start = rs->getDouble(1);
   double end = rs->getDouble(2);
   std::string batch = rs->getString(3);
   std::string agent = rs->getString(4); // CRASH!
Here is the exception that I get when I try to debug:
"Unhandled exception at 0x00D82CB8 in DARTester.exe: 0xC0000005: Access violation reading location 0x0000005."
Any help would be greatly appreciated.

It is my fault. I use Fedore Core 4 and gcc4.0. By default it linking with libstdc++.6.so, but when I linkint direct with libstdc++.5.so it OK.
Thank you for support!

Problem with getString() in OCCI

/* 
My name is Chandra, 
I am facing a problem in retriving many records from a table using OCCI 
I am using VC6.0 in WindowXP - SP2 with Oracle 10G client 
 
Here is my Example 
I have no issue with the program when there are 10 records in emp table 
where as I am getting an error when there are 20 records. 
Code is executing till the end 
it also printed Finished Printing which is in main 
and gave the following error 
 
ERROR::: 
1.exe has encountered a problem and needs to close. 
we are sorry for the inconvenience 
Error Signature is saying that it happend with Mod Name ntdll.dll and 
ModVer: 5.1.2600.2180 and Offset:00010fc2 
When I tried by modifying line 
emp1.ename = rs->getString(1); 
to 
emp1[i].ename = "Chandra"; 
it is working Perfectly 
Please advice what is wrong with getString(1); 
Is there any other function which I can use to store the value of ename into a string? 
If there is please advice me how to use. 
Thanks a lot for your support

J2ME problem with threads

Hi all,
I would like to ask you for a help. I need to write a small program at my university. I started to write a midlet which function would be to countdown time for sports activities. I woul like to start a new thread - the one that counts down - and at the same time make the main thread sleep. After the "countdown" thread finishes, the main thread wakes up and waits for user input.

Groovemaker,
Your Licznik class has a member m of type monitor, which has not been instantiated (in other words is null) hence, when calling m.put() you get NullPointerException. Please also mind, that using Thread.sleep(1000) is not an accurate way of measuring time.
If I may, please use recommended for Java class naming conventions - some of your names use lower case, while other don't which is confusing to the reader.

Query update on each iteration problem (MS SQL Sever / ODBC / Native Driver

Hello,
I�ve been working to learn some Java and now JDBC over the past 10 or so months.
I think I have a general understanding of how to perform queries and work with data using JDBC. However, I�ve run into a problem. I�m trying to do a query of a set of data in a database based on the value of a status column. I want to loop over the messages and perform various functions with the data then update their status in the database. It�s preferable to do these 250 to 1000 rows at a time, but no more and no less.
I�m connecting to MS SQL Server 2000, currently with ODBC. I�ve also tried it with the Java SQL Server 2000 drivers provided by Microsoft with the same results.
I�ve found that I can do a one table query and loop though it with a while (rs.next()) {�} and run an Update statement with executeUpdate on each iteration without any problems, no matter the number of rows returned in query.
I have not been able to use the updateString and updateRow inside the while loop. I keep getting errors like this at the line with the updateRow():
Exception in thread "main" java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Row update failed.
This occurs no mater how many rows I select, 1 or more.
The real problem I�ve been having is that the query I need to loop though joins across several tables and returns some rows from some of those tables. This only seems to work when I query for 38 or less selected rows and I use an Update statement with executeUpdate on each iteration. The updateString and updateRow methods never work. Any number of rows selected greater than 38 causes a deadlock where the Update is waiting for the select to compete on the server and the Update can�t proceed until the Select is complete.
As I stated above I�ve tried both ODBC and the native SQL Server driver with the same results. I have not tried any other databases, but that�s moot as my data is already in MS SQL.
Questions:
How can I avoid or get around this 38 row limit without selecting each row, one at a time?
What am I doing wrong with the updateString and updateRow?
Is there a better approach that anyone can suggest?
Here�s some sample code with the problem:
import java.sql.*;
public class db1{
     public static void main(String[] args) throws Exception{
          Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
          String url = "jdbc:odbc:eBrochure_live";
          Connection con = DriverManager.getConnection(url, "sa", "d3v3l0p");
          Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
          Connection con = DriverManager.getConnection("jdbc:microsoft:sqlserver://dcm613u2\\dcm613u2_dev:1433", "sa", "d3v3l0p");
          Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
          Statement stmt2 = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
          stmt.executeUpdate("USE [myDatabase]");
          stmt2.executeUpdate("USE [myDatabase]");
          String qGetMessages = "SELECT TOP 250 t1.messageUUID, t1.subjectHeader, t2.emailAddress as toAddress " +
          "FROM APP_Messages as t1 JOIN APP_addressBook_contacts as t2 " +
          "     On t1.toContactID = t2.contactID " +
          "WHERE t1.statusID = 'queued'";
          ResultSet rs = stmt.executeQuery(qGetMessages);
          while (rs.next()) {
               String messageUUID = rs.getString("messageUUID");
               String subjectHeader = rs.getString("subjectHeader");
               System.out.println(messageUUID + " " + subjectHeader);
               String updateString = "UPDATE APP_Messages " +
                    "SET statusID = 'sent' " +
                    "WHERE messageUUID = '" + messageUUID + "' ";
               stmt2.executeUpdate(updateString);
          con.close();
Thanks for the help,
Doug Hughes

// sorry, ps.close() should be outside of if condition
String sql = "UPDATE APP_Messages SET statusID = 'sent' WHERE messageUUID = ?";
Statement statement = con.createStatement();
PreparedStatement ps = con.prepareStatement(sql);
ResultSet rs = statement.executeQuery("your select SQL");
if ( rs.next() )
ps.clearParameters();
ps.setString(1, rs.getString("your column name"));
ps.executeUpdate();
ps.close();
rs.close();
statement.close();

Problem Using HTTP Dispatcher -- Could Not able to get the data in JSP

Thanks and regards

HI Prabhat,
Thanx for your reply, I worked out and able to receive the data in oracle database, Actually there was some problem in insert Query. Now I have tested the same... and able to edit the same in the Database.....
But I am facing a new problem, Http Dispatcher in SES console is displaying all the Events generated as well as event in Que but there is no events in the Event Send. I guess it is not able to send the events.....?????
Event statical is showing like this
Events Received: 0 (0.00/sec)
Events Generated: 311 (0.19/sec)
Events Sent: 2 (0.19/sec)
Queued Events: 309 (0.19/sec)
Kindly suggest where is the problem, Is it a JSP problem or OSES end problem.....
Thanks and regards
Nasim

Problems with varchar2 column and a select statement

Hi to all,
I am new to ODP...so I would really appreciate your help..
I am having problems with using the following code:
con.ConnectionString = "User Id=bla;Password=bla;Data Source=bla;";
string cmdQuery = "SELECT * from try where data ="+textBox1.Text+"";
OracleCommand cmd = new OracleCommand(cmdQuery);
cmd.Connection = con;
cmd.CommandType = CommandType.Text;
OracleDataReader reader = cmd.ExecuteReader();
while (reader.Read())
MessageBox.Show(reader.GetString(0)+"");
cmd.Dispose();
con.Close();
where:
data is the name of a field in the table
textBox1 is the name of a text box where the user inserts the values..
The error that appears is "Invalid identifier"..
I hope it makes sense...and please help...

Hi,
I'm fairly sure it IS the single quotes actually. Print out the string you're trying to excute, then try it outside odp.net, does it work?
For example:
SQL> select * from dual where dummy=foo;
select * from dual where dummy=foo
ERROR at line 1:
ORA-00904: "FOO": invalid identifier
SQL> select * from dual where dummy='foo';
no rows selected
Cheers,
Greg

Problem in java.awt.print

Hi here is my code .
I am generating page dynamically and passing to printer.
Printing Functionalities working file. But I am taking some data from database (Access). And in this code for example i have 4 records in Database and i am generating 4 pages (each page for resord).
I am getting only 2 records. And for other two records i am getting blank page.
Reason is My ResultSet object is moving to next record twice.
I mean if i have 6 records i get only 3 pages.
If i have 10 records i get only 5 pages and If i have 1 record i dont get any page.
How shall i solve this problem.
Thanx in advance.

     System.out.println("Connection is Proper");
     }catch(Exception e){
          System.out.println("Exception at Connection"+e);

I am not sure this..
Instead of if pls give while and check:
try{
while(rsValue.next()) {
g.setFont(fntHeading);
g.setColor(Color.red);
g.drawString("Main Report",200,100);

JSP and Java Beans with Database Problem

hellow, this is my first posting and i hope to help me as fast as you can...
my problem is simplly i cant get any data from the database (whatever the database it is, i test it with MS Access and MySQL server) when i use a bean, But if i put my connection statement in the JSP file thair is no problem... ???? !!!!
for example i have a class "Authentication" that have a method to test if the username and password is correct or not and return 1 if true, 0 if false, -1 if thair are some problem in connecting DB.
now if i create a normal java application that uses this method, it's work and no problems, BUT if i used a JSP page to use this method it's return allways -1

Well Well Well..
That would not work...
What you have to do is save the uploaded file content on to a location and then pass the fileName as a request parameter to a deidicated which displays the contents of that file.
Just as an example
<html>
<head>
<title>File Upload Display</title>
</head>
<body>
<%
//ServletOutputStream sout=response.getOutputStream();
StringBuilder strBuilder = new StringBuilder();
int count=0;
String f;
f=request.getParameter("filedb");
DBManager dbm = new DBManager();
//dbm.createTable("mms3");
//log.info("In JSP : "+ f);
//dbm.insert_data(f,"mms3");
%>
<%
if (ServletFileUpload.isMultipartContent(request)){
ServletFileUpload servletFileUpload = new ServletFileUpload(new DiskFileItemFactory());
List fileItemsList = servletFileUpload.parseRequest(request);
strBuilder.append("<?xml version=\"1.0\" encoding=\"UTF-8\" ?>").append('\r').append('\n').append("<xpage version=\"1.0\">").append('\r').append('\n');
String optionalFileName = "";
FileItem fileItem = null;
Iterator it = fileItemsList.iterator();
ServletOutputStream outputStream=null;
while (it.hasNext()){
 FileItem fileItemTemp = (FileItem)it.next();
%>
Name-value Pair Info:
Field name: <%= fileItemTemp.getFieldName() %> 
Field value: <%= fileItemTemp.getString() %> 
<%
if (fileItemTemp.getFieldName().equals("filename"))
 optionalFileName = fileItemTemp.getString();
if(!fileTempItem.isFormFiled()){
 String fileName = fileItem.getName();
 fileItem.write(optionalFileName);
%>
Uploaded File Info:
Content type: <%= fileItem.getContentType() %> 
Field name: <%= fileItem.getFieldName() %> 
File name: <%= fileName %> 
<%
if(fileItem.getContentType().equals("image/jpeg") || fileItem.getContentType().equals("image/pjeg")) {
%>
<img src="FileServlet?fileName=<%=optionalFileName%>"
<%
%>
</body>
</html>a sample code snippet for FileServlet.
String fileName = request.getParameter(fileName);
File file = new File(fileName);
 if(!file.exists())
 return;
// If JSP
String mimeType = application.getMimeType("fileName");
 If you are using servlet
 String mimeType = this.getServletContext().getMimeType(fileName);
 response.setContentType(mimeType);
 response.setHeader("Content-Disposition","inline;filename=\\"+fileName+"\\");
BufferedOutputStream out1 = null;
InputStream in = null;
if(mimeType == null)
 mimeType = "application/octet-stream";
try{

 response.setContentLength(in.available());
 BufferedOutputStream out1 = new BufferedOutputStream(response.getOutputStream(),1024);
 int size = 0;
 byte[] b = new byte[1024];
 while ((size = in.read(b, 0, 1024)) > 0)
 out1.write(b, 0, size);

}finally{
 if(out1 != null){
 try{
 out1.flush();
 out1.close();
 }catch(Exception e){}
 if(in != null){
 try{in.close();}catch(Exception e){}
} Hope that might answer your question :)
However,this is not the recommended way of doing this make use of MVC pattern.Would be a better approach.
you might think of googling on this and can findout what is the best practise followed for problems of this sort

Problem reading RFC values from IRecordSet !!!!

Hi All,
I am having some problem reading values from IRecordSet. Can not seem to parse the output structure from RFC. AM using connector gateway service to execute BAPI_EXCHRATE_GETCURRENTRATES.
Here is the code,
MappedRecord input = rf.createMappedRecord("input");
input.put("DATE",new String("01011990"));
input.put("DATE_TYPE", new String("V"));
input.put("RATE_TYPE", new String("M"));
MappedRecord output = (MappedRecord) ix.execute(ixspec, input);
Object rs = null;
IRecordSet recSet = null;
Object result = output.get("EXCH_RATE_LIST");
if (result == null) {
response.write(" null");
rs = new String(" ");
} else if (result instanceof IRecordSet) {
IRecordSet irs = (IRecordSet) result;
response.write(" Got some dataaa");
IRecordMetaData rsmd = null;
rsmd = irs.retrieveMetaData();
irs.beforeFirst();
while(irs.next()){
response.write("Row::"+irs.getString("RATE_TYPE")+" "+irs.getString("FROM_CURR")+" "+irs.getString("EXCH_RATE"));
Am getting the pritn statement, Got Some Data on the PDK component.
But somehow not able to read the values from IRecordSet
What is the mistake here?
Pls help
Edited by: Aakash Jain on Oct 11, 2008 12:22 AM

Hi
Try in this way.
IRecordSet resultTable = (IRecordSet)outputParams.get("TABLE_NAME");
for(resultTable.beforeFirst(); resultTable.next(); ) {
response.write(resultTable.getString(0));
response.write(resultTable.getString(1));
Thanks
