Execution of queries - retreiving a part of data from database.

I use EJB3, OC4J, Oracle9i.
I try to get a part of data from database.
I write such code:
String sql = "SELECT object(o) FROM some_table o ORDER BY o.username ASC";
Query partialListQuery = em.createQuery(sql);
partialListQuery.setFirstResult(0);
partialListQuery.setMaxResults(10);
List<IssueHours> issueHoursList = partialListQuery.getResultList();
and in logs I get:
2006.11.16 11:09:06.224--ServerSession(977)--Connection(4561)--Thread(Thread[ApplicationServerThread-0,5,RequestThreadGroup])--SELECT ID, NUMBER, HOURS, SUMMARY, PROJECT_NAME, USERNAME FROM SOME_TABLE ORDER BY USERNAME ASC
It is interesting whether some optimized query is built for retreiving a part of data or all data is carried from database to the server-side and filterred there.
If all data is retreived, how can I avoid that?is there any configuration? or... must I create myself optimized query?

When maxResults is set the JDBC maxRows is set which allows the database to optimize what results are returned. Only the maxResults are returned from the database.

Hi,
The trouble in "<default>:" - if you set XML_PATH as C:\DATA_FILE\www.xml instead <default>:C:\DATA_FILE\www.xml- it will work correctly.

How to retrieve data from database to the structure(complicated)

Hello everyone:
I want to retrieve data from database to the structure. but the structure defined like this below:
TOLERANZOB LIKE QAMV-TOLERANZOB
TOLERANZOB1 LIKE QAMV-TOLERANZOB
so how can I retrieve the data from the database ? make sure that the two fields contain data both.
Thanks in advance .
Regards
Nick

Hi Nick,
To retreive data for TOLERANZOB from QAMV,
If you know the key fields then use
SELECT SINGLE TOLERANZOB FROM QAMV INTO TOLERANZOB WHERE keyfields.
else, you can use
SELECT TOLERANZOB FROM QAMV UPTO ONE ROWS INTO TOLERANZOB WHERE....
Once you retreive the data using the select query, you can check if it is initial and if not move the data from TOLERANZOB to TOLERANZOB1.
Reward points for helpful answers.

How to populate Adobe LiveCycle Designer generated PDF Forms with data from Database in Windows app

Hi
I have a PDF template designed in Adobe LiveCycle Designer. This template has form fields which needs to be filled with data programmatically. I am using windows application in C#.Net 2005 in which I want to retrieve data from database and merge this data into PDF form in respective fields.
How this can be achieved?
I searched a lot & I found that we can process the XDP file generated from PDF to acheive this. I created the XDP file out of the PDF template created in designer. But I don't know how to merge data from database into that XDP file in respective fields and again convert this XDP file back to PDF programmatically. Can anybody help me ? This is urgent.
Thanks in advance.

It's a classpath problem. Either you mistyped the class name, or you don't have the class in your classpath. I think Oracle's drivers come in db12.zip or db12.jar or some such. Whatever that jar or zip file is, it has to be in your classpath, but it's not.
Or it is in your classpath, but you're in an appserver context where the classloader that the container provides for your app uses something other than the classpath variable. For instance, in tomcat, the jar file would be uder webapps/yourApplication/WEB-INF/lib I think.

How to display data from Database individually??? Anyone can help ?

HI,
i i had select a row of data from database using ,
/* Query * From Table RESOURCEORDER where po = selected no and project = selected project */
     public ResultSet getAllData() throws SQLException
     getConnection();
     Statement stmt = conn.createStatement();
     ResultSet rs = stmt.executeQuery("SELECT * FROM RESOURCEORDER WHERE PROJECT = '" + getSelProject() + "' and PURCHASEORDERNO = '" + getPo() + "'" );
     return rs;
After that , how do i display the data individually ?
Eg select data is ('projectA','7891203-1', '10-4-2005','lcd',2000,'121-45217-8','electrical','pending','donwong')
i want to display them individually, like this in a page

Can anyone help ? cos i'm new to JSP ......Thanks alot!!!!!
Regards,
khim

I assume PO being a unique key, will always return 1 row from db.
public String[] getAllData() throws Exception
getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM RESOURCEORDER WHERE PROJECT = '" + getSelProject() + "' and PURCHASEORDERNO = '" + getPo() + "'" );
String [] returnValue = new String[9];
while(rs.next())
returnValue[1] = rs.getString("colname");
returnValue[2] = rs.getString("colname");
///and so on
return returnValue;
}Once you get that you could individually view it by setting a loop to run through the returned array.
Hope it helps

 // output resultset
 while ( rs.next() )
 numbers [row][0]= rs.getString("ID");
 numbers [row][1]= rs.getString("name");
 row++;
 // close resultset
 rs.close();
thanks,Devi

The exception is been thrown simply because you assigned '0' to the 'row' variable, indicating a zero length of the array. In fact you should assign the row count to it.
After all, don't do that. Make use of the Collection framework and map the ResultSet to a Collection of DTO's.
List<User> users = new ArrayList<User>();
while (resultSet.next()) {
 User user = new User();
 user.setID(resultSet.getString("ID"));
 user.setName(resultSet.getString("name"));
 users.add(user);
}

extract data from database tables and download in pdf and csv
hi how can i re-write my old form procedure in adf java. the procedure used to extract data from diffirent table and dowload the data in pdf and csv.am not downloading image, i what to extract data from diffirent tables in my database and download that data in pdf and csv. i would like to write this in java adf.i just what direction am not asking anyone to do my work this is my learning curve
