Result Set Problem

Hi
I am Fetching a Huge Number of records(50,000) from the database and Displaying them on the screen in a JSP page.. But its taking a very long time..Is there any Process that can speed up the fetching of records from the database and display it on the screen..And that too I dont want to use any Entity Bean.. I want the solution only in JSP using a ResultSet.. can any one help in finding the Solution...
bye
sanju

When displaying such a number of records in a HTML table, it might be IE's table rendering process that takes most of the time (the "pre" tag is even worse ...). Usually I can't imagine that it makes sense to display 50000 records on one page, so I agree with bluegreenvn: break the resultset into several pages of e.g. 50 records each and add some navigation functionality.

Result Set problem!!!Plz urgent

Hi,
I am using jsp page with database connection.In jsp page i have two button called move next and move previous.
In database 2 records are there.If i open the jsp page first record will be displayed.If i click next record it showing 2nd record.If i click previous record it showing 1st record.Once again if i click next record it is showing that record not found...........What may be the problem????.
Note:For each time button click i will pass the result set object in session variable.Whether it is a correct one..
Plzz help me ya...........

this is for move next:::
ResultSet result=null;
Connection connection=null;
String candyid="";
result = (ResultSet)session.getAttribute("resget");
result.next();
if(!result.next())
%>
<Script>
alert("Record Not Found");
</Script>
<%
result.previous();
candyid=result.getString(1);
session.setAttribute("resget",result);
%>
<input type=hidden name="hide" value="yes">
<input type=hidden name="nextid" value=<%= candyid %>>
<Script>
document.AddCandetails2.action="modifyCandidate1.jsp";
document.AddCandetails2.submit();
</Script>
<%
else
candyid=result.getString(1);
System.out.println("candi next id"+candyid);
session.setAttribute("prevresget1",result);

Did you forget to put the SQL statement in when you used createStatement? I added it below:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection("Jdbc:Odbc:IMSMC","sa","");
String sql="select * from <Table Name> ";
Statement stmt=conn.createStatement(sql, ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
Does the JDBC-ODBC bridge driver accomodate any of these settings you're trying?
The problem shouldn't have anything to do with Tomcat. Sounds like a JDBC driver issue to me. Try to reproduce the error without Tomcat, and then see if adding the SQL corrects things at all.
I'd read the docs to see if the bridge driver has these features. I don't think it's up to the full standard.

Result set problem with GROUP BY

hi there, this should be the simplest of queries but.........
when run, the list size is 13, this is the number of letting units in the table. it appears not to be grouping by the property id.if it was doing this there should only be 8 rows. having said this, the while loop should output the count of each row, it does this 8 times with the correct counts. it then crashes with a invalid curser error. it appears the query is workig correctly but the resultset thinks its got 13 rows when it only has 8.
accessing ms access db
using jdbc:odbc
heres the code
searchResults = stmt.executeQuery(
"SELECT Count(*) AS FreeUnits " +
"FROM letting_units " +
"GROUP BY letting_units.property_id");
searchResults.last();
listSize = searchResults.getRow();
searchResults.beforeFirst();
System.out.println(listSize);
while (searchResults.next())
System.out.println(searchResults.getString(1));
hope someone can help me
cheers
andy

It's not the problem with GROUP BY. You should use scrollable result set to move in both directions (forward and backward).
In your code
searchResults.beforeFirst(); line may return false. So you will get the searchResults.next() false. Once you move forward in non-scrollable cursor cannot come back. So when you create the statement object use TYPE_SCROLL_INSENSITIVE or TYPE_SCROLL_SENSITIVE constants provided in the ResultSet.

Result set problems

I am trying to comparing two tables(assuming they both have the same columns) records by records in two differnet schemas and print out their discrepancy.
I am using jdbc oracle connection to my database. In main, I'm creating two new tables object and call getTableRecords(schema, tableName)
and then do the comparsion: table1.compare(table2)
public Table getTableRecordss(DatabaseInfo dbInfo, Table table)
String sql = ("Select * from " + table.getName() ");
try
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stmt.executeQuery(sql);
rs.setFetchSize(1000);
String tempString;
while (rs.next())
Record record = new Record();
tempString = rs.getString(i+1);
if(tempString == null)
tempString = "";
record.addValue(tempString);
table.addRecord(record);
stmt.close();
}catch (Exception e)
e.printStackTrace();
System.exit(1);
closeConnection();
This proram ran okay if the row sizes of a table is less than 200,000, but it will get heap space size Outof Memory error if it is more than that.
I did try to increase the heap size by -Xmx1024m and still didn't work. Is there any other ways to get this to work? Thanks in advance.

I need this because I wanted to make sure the table from db1 get streams over to db2What are you doing? Specifically? Are you trying replicate or implement your own RAID? Java is not the way to go for that.
Is there a way i can get result set by batches?Sure, but nobody can tell you how to do that. You need to figure that out for yourself because we have no idea what your data looks like. But for example, if your data contained a bunch of cars, you could do it in batches like Toyota first, then Ford, then Yugo (probably a small batch)

Scroll result set problem

I am using jdk1.3 and i am having a problem using methods such first() ,last(), previuos update,delete()...
and how to upgrade jdbc1.0 to jdbc2.0
Thanks

I am using jdk1.3 and i am having a problem using
methods such first() ,last(), previuos
update,delete()...And those problems are?
and how to upgrade jdbc1.0 to jdbc2.0You don't.
1.3 comes with 2.0 (or perhaps 2.1.)
If your driver (which is not part of JDBC) does not support those features then you get a newer driver or a different driver, presuming that is even possible.

Result set Problem...URGENT

I have doubt about my getObject method, my database attribute got varchar and number, can i use getObject method to retrieve???
Because i encounter null error when i use getObject for my database.....
I f any sample to elobrate will be better.

It will work just fine.
The VARCHAR will be retrieved as a String
The NUMERIC will be retrieved as a BigDecimal
See here for the rest of the default conversions:
http://java.sun.com/j2se/1.3/docs/guide/jdbc/spec/jdbc-spec.frame14.html
If the column in the row has a NULL value, however, you will get a null reference back; presumably that's what is happening here. If not, post the code in question and we'll take a look at it.

Result set looping and arrays??????????

Hey i have a result set problem in using an applet connected to a database.
After i have accessed a database, i am using a result set to store these values, then put them into arrays to out put to screen. im using:
count = 0;
while(rs.next())
lecturer[count] = rs.getString("FirstName") + " " + rs.getString("Surname");
room[count] = rs.getString("Room_No");
sentence = rs.getString("Subjects");
if(sentence.length()>12)
space = sentence.indexOf(" ");
subject[count] = sentence.substring(0,(space));
subject2[count] = sentence.substring((space+1),sentence.length());
else
subject[count] = sentence;
subject2[count] = " ";
timeslot[count] = rs.getInt("Time_slot");
count++;
resCount++;
rs.close();
stm.close();
The while is there untill there are no more values in the result set. This should work(in theory). But for some reason the while loop goes around and around until 'size' (which is the size for all the arrays) is reached. This is a set value at the start of the applet. But whenever i change it the while loop goes around that many times without fail. this results in duplicate outputs to screen, that i dont want.
Anyone got any ideas????????????

This flow doesn't make too much sense to me. Why are you setting an absolute limit on the length of the array, if it should really be determined by the number of rows in your resultset. It sounds like you would be better off using a Collection class, like:
List names = new ArrayList();
while(rs.next()) {
names.add(rs.getString("name"));
}

Problem in Retrive values from result set

I have a class where i do all database operation .First i fire select query and take values from result set and based on that value i fire update query.
Problem is that i am not getting all values from result set . i get only last value and when i fire update query i get error as :Resultset is closed.
I am using acess and java.

You probably are using the same Statement object for both queries? Try creating separate Statement objects for each query. (My guess is this a problem with the way you're using JDBC, not a Servlet issue.)

does your jdk include jdbc 2.0? Is your driver updated to support jdbc 2.0 features? have you recently updated either(and forgot to change the classpath)?
I am running jdk 1.3 and oracle thin(classes12.zip) have not had problems creating/using scrollable resultsets??

Problem opening 2 result sets

Hi we are having problems with leaking database connections. We are using the jdbc debug features of oc4j (9.0.2).
Basically we connect to database 1, do a query and open a result set, then create a connection to database 2 and try to execute a query on it. The problem is that if the first's resultset is open, the debugging complains that there are multiple open result sets. This is leading to database connections not getting release when they should be.
Here's an example of the code we are using (which is in a stateless session bean):
public void test(){
try {
Connection connection;
DataSource dataSource;
Context context = new InitialContext();
dataSource = (DataSource) context.lookup(Constants.NHHDC_DATABASE);
connection = dataSource.getConnection();
PreparedStatement statement = null;
ResultSet resultSet = null;
statement = connection.prepareStatement(" SELECT 'X' FROM DUAL");
resultSet = statement.executeQuery();
resultSet.next();
DataSource reamsDataSource;
Context reamsContext = new InitialContext();
reamsDataSource = (DataSource) reamsContext.lookup(Constants.REAMS_DATABASE);
Connection reamsConnection = reamsDataSource.getConnection();
PreparedStatement reamsStatement = null;
ResultSet reamsResultSet = null;
reamsStatement = reamsConnection.prepareStatement("SELECT 'X' FROM DUAL");
System.out.println("LAST STATEMENT");
reamsResultSet = reamsStatement.executeQuery();
System.out.println("FINISHED");
reamsResultSet.close();
reamsStatement.close();
reamsConnection.close();
resultSet.close();
statement.close();
connection.close();
} catch (NamingException e) {
System.out.println("naming error " + e.getMessage());
} catch (SQLException e) {
System.out.println("sql error " + e.getMessage());
The error coming from the debug is:
*********** OPEN SETS: ************
java.lang.Exception: com.evermind.sql.DebugPreparedResultSet@5e9f1
Is it not possible to have 1 resultset open on one database and a separate one on a different database? I know the example above could be written to close the result set first, but this is a simplified example of something we are doing just to hightlight the problem.
Any ideas appricated on why this complains.
Thanks
Andrew Moore

hi Andrew,
Just a hint: we are using more than 1 database connections at the same time. but in this case all datasources have to be non-emulated.
check this, maybe its the prob @ yours.
4 non-emulated datasources check the server guide of oc4j ..

Problem in creating Saved Result Set (SRS) in OBIEE 10.1.3.4

Hi,
We have migrated Siebel Analytincs 7.8.5 to OBIEE 10.1.3.4, and we are now unable to create any SRS from OBIEE though we can create Segment and marketing cache for the segment.
We did the following steps -
1. Unisntall Siebel Analytincs 7.8.5
2. Install OBIEE 10.1.3.4
3. Use MIGRATE tool (sawmigrate) to migrate RPD & WEBCAT
4. We have ALTERed the SRS tables - M_SR_HEADER, M_SR_ACCOUNT (as in OBIEE version there are many new columns have been added)
5. We passed GLOBAL CONSISTENCY in the RPD
6. We followed the steps in the document *"Oracle®Marketing Segmentation Guide Version 10.1.3.4 July 2008"*
7. We created a Saved Result Set Format as instructed in the document - here we are very confused to select the list of columns - we don't know what should be the excat source / format
8. Then we click the SRS create button
9. We got the below error -
Error Codes: QS2QOLYY:GDL67CY9:IHVF6OM7:OPR4ONWY:U9IM8TAC
Error in getting cursor for WorkNode (Id:0)
Authentication Failure.
Odbc driver returned an error (SQLDriverConnectW).
*State: 08004. Code: 10018. [NQODBC] [SQL_STATE: 08004] [nQSError: 10018] Access for the requested connection is refused. [nQSError: 43001] Authentication failed for Administrator in repository Star: invalid user/password. (08004)*
Can anyone help us to resolve the issue ?
A quick response is much much appreciated.
Many Thanks,
Prasanta

Hi,
It seems like you didnt setup the Administrator user for Saved Result Sets as it mentioned in the Marketing Segmentation Guide.
Here is an extract from the guide:
Setting Up the Web Administrator for Managing Cache and Saved Result Sets
Some queries issued by the segmentation engine require the use of the Execute Physical stored
procedure. These queries include delete statements on the cache, delete statements on the saved
result sets, and insert statements for the cache and saved result set. The Execute Physical stored
procedure must be run by a user with administrator privileges. The administrator user is set up in
the instanceconfig.xml file.
NOTE: The BI Administrator password and login parameters are case sensitive.
To set up the administrative user in the instanceconfig.xml file
1 Open a command shell and navigate to the <OracleBI>/web/bin, where <OracleBI> represents
the root directory of the installation.
2 Execute the following command:
cryptotools credstore -add -infile <OracleBIData>/web/config/credentialstore.xml
3 When prompted, enter the following values:
Credential Alias: admin
Username: Administrator
Password: <enter Admin password here>
Do you want to encrypt the password? y
Passphrase for encryption: <password >
Do you want to write the passphrase to the xml? n
File "<OracleBIData>/web/config/credentialstore.xml" exists. Do you want to overwrite it? y
4 Open the credentialstore.xml file and verify that the following section has been created:
<sawcs:credential type="usernamePassword" alias=“admin">
<sawcs:username> Administrator </sawcs:username>
<sawcs:password>
<xenc:EncryptedData>

How can I use ONE Text search iView to event/affect mutliple Result Sets?

hello everyone,
i have a special situation in which i have 6 flat tables in my repository which all have a common field called Location ID (which is a lookup flat to the Locations table).
i am trying to build a page with a free-form text search iView on Table #1 (search field = Location ID). when I execute the search, the result set for Table #1 is properly updated, but how do I also get Result Set iViews for Tables #2-6 to also react to the event from Text Search for Table #1 so that they are updated?
i don't want to have to build 6 different text search iViews (one for each table). i just want to use ONE text search iView for all the different result set tables. but, in the documentation and iView properties, the text search iView doesn't have any eventing.
if you have any suggestions, please help.
many thanks in advance,
mm

hello Donna,
that should not be a problem, since you are detailw with result sets and detail iviews because custom eventing can be defined for those iviews.
Yes, it says "no records" found because an active search and record selection havent' been performed for it (only your main table does).
So, yes, define a custom event, and pass the appropriate parameters and you should be fine.
Creating a custom event between a Result Set iView and an Item Details iView is easy and works. I have done it.
See page 35 of the Portal Content Development Guide for a step-by-step example, which is what I used.
For my particular situation, the problem I'm having is that I want the Search Text iView's event (i.e., when the Submit button is pressed) to be published to multiple iViews, all with different tables. Those tables all share some common fields, which is what the Search iView has, so I'd like to pass the search critera to all of the iViews.

Query Error Information: Result set is too large; data retrieval ......

Hi Experts,
I got one problem with my query information. when Im executing my report and drill my info in my navigation panel, Instead of a table with values the message "Result set is too large; data retrieval restricted by configuration" appears. I already applied "Note 1127156 - Safety belt: Result set is too large". I imported Support Package 13 for SAP NetWeaver 7. 0 BI Java (BIIBC13_0.SCA / BIBASES13_0.SCA / BIWEBAPP13_0.SCA) and executed the program SAP_RSADMIN_MAINTAIN (in transaction SE38), with the object and the value like Note 1127156 says... but the problem still appears....
what Should I be missing ?????? How can I fix this issue ????
Thank you very much for helping me out..... (Any help would be rewarded)

You may ask your basis guy to increase ESM buffer (rsdb/esm/buffersize_kb). Did you check the systems memory?
Did you try to check the error dump using ST22 - Runtime error analysis?

Large query result set

Hi all,
At the moment we have some java classes (not ejb - cmp/bmp) for search in
our ejb application.
Now we have a problem i.e. records have grown too high( millions ) and
sometimes query results in retrieval of millions of records. It results in
too much memory consumtion in our ejb application. What is the best way to
address this issue.
Any help will be highly appreciated.
Thanks & regards,
Parvez

you can think of following options
1) paging: read only few thousands at a time and maintain a index to page
through complete dataset
2) caching!
a) you can create a serialized data file in server to cache the result set
and can use that to browse through. you may do on the fly
compression/uncompression while sending data to client.
b) applet based solution where caching could be in client side. Look in

Thanks Slava Imeshev,
We already have search criteria and a limit. When records exceeds thatlimit
then we prompt user that it may take sometime, do you want to proceed? If
he clicks yes then we retrieve those records. This results in lot ofmemory
consumtion.
I was thinking if there is some way that from database I can retrieve some
block of records at a time rather the all records of a query. I wander how
internet search sites work, where thousnds of sites/pages match criteriaand
client can move back & front on any page.

Hi chauhan,
You may want to narrow search criteria along with processing a
limited number of resulting records. I.e. if the size of the result
is bigger than a limit, you stop fetching results and notify the client
that search criteria should be narrowed.
HTH.
