Minus and passing the result set

I have a query in a procedure....let us say "test.prc":
select A.VALUE from TABLE A
where A.VALUE_ID = get_rec.VALUE_ID minus
select B.VALUE from TABLE B
In the above query, I am passing the "get_rec.VALUE_ID" from a cursor above the query.
Now is there a way to capture the result set of the above minus operation and pass the result set to the calling sql program (called "call_test.sql")?
Thanks,
Chiru

I got what I was trying to do...
I have 1 more question though....I am printing out my output using dbms package from sql*plus...using the following command
dbms_output.put_line(nvl('Flex Value set Id : '||get_rec.flex_value_set_id,0)||' values that have no corresponding alias : ' || nvl(v_flex_val,0));
"get_rec.flex_value_set_id" gets passed in from my cursor above the dbms statement.
and it looks like below:
Flex Value set Id : 20118 values that have no corresponding alias : 00
Flex Value set Id : 20118 values that have no corresponding alias : 10
Flex Value set Id : 20118 values that have no corresponding alias : 11
Flex Value set Id : 20118 values that have no corresponding alias : 20
Flex Value set Id : 20118 values that have no corresponding alias : 30
Flex Value set Id : 20124 values that have no corresponding alias : Standard
Is there some way to neatly break when the value set id changes? ...ie., make it print output something like below:
Flex Value set Id : 20118
values that have no corresponding alias : 00
values that have no corresponding alias : 10
values that have no corresponding alias : 11
values that have no corresponding alias : 20
values that have no corresponding alias : 30
Flex Value set Id : 20124
values that have no corresponding alias : Standard
Thanks,

JSP Servlet and convert the result set of an SQL Query To XML file

Hi all
I have a problem to export my SQL query is resulty into an XML file I had fixed my servlet and JSP so that i can display all the records into my database and that the goal .Now I want to get the result set into JSP so that i can create an XML file from that result set from the jsp code.
thisis my servlet which will call the jsp page and the jsp just behind it.

<%
// Identify a carriage return character for each output line
int iLf = 10;
char cLf = (*char*)iLf;

File outputFile = *new* File("C:\\Users\\user\\workspace1\\demo\\WebContent\\YourFileName.xml");
//outputFile.createNewFile();
FileWriter outfile = *new* FileWriter(outputFile);
// the header for XML file
outfile.write("<?xml version='1.0' encoding='ISO-8859-1'?>"+cLf);
try {
// Define connection string and make a connection to database
Connection conn = DriverManager.getConnection("jdbc:derby://localhost:1527/SAMPLE","app","app");
Statement stat = conn.createStatement();
// Create a recordset
ResultSet rset = stat.executeQuery("Select * From posts");
// Expecting at least one record
*if*( !rset.next() ) {
*throw* *new* IllegalArgumentException("No data found for the posts table");
outfile.write("<Table>"+cLf);

outfile.write("</Table>"+cLf);
// Everything must be closed
rset.close();
stat.close();
conn.close();
outfile.close();

Please state your problem that you are having more clearly so we can help.
I looked at your code I here are a few things you might consider:
It looks like you are putting freely typed-in comments from end-users into an xml document.
The problem with this is that the user may enter characters in his text that have special meaning
to xml and will have to be escaped correctly. Some of these characters are less than character, greater than character and ampersand character.
You may also have a similiar problem displaying them on your JSP page since there may be special characters that JSP has.
You will have to read up on how to deal with these special characters (I dont remember what the rules are). I seem to recall
if you use CDATA in your xml, you dont have to deal with those characters (I may be wrong).
When you finish writing your code, test it by entering all keyboard characters to make sure they are processed, stored in the database,
and re-displayed correctly.
Also, it looks like you are putting business logic in your JSP page (creating an xml file).
The JSP page is for displaying data ONLY and submitting back to a servlet. Put all your business logic in the servlet. Putting business logic in JSP is considered bad coding and will cause you many hours of headache trying to debug it. Also note: java scriptlets in a JSP page are only run when the JSP page is compiled into a servlet by java. It does not run after its compiled and therefore you cant call java functions after the JSP page is displayed to the client.

Remote Call to Blazeds and displaying the result set in grid

Hi,
I want to call a remote method using Flex application from Blazeds and display the values in DataGrid. Can anyone help in this ?
-- I am using AMFChannel
-- The method to be called is PolicyApnVO.getPoliciesApn()
-- Please advice any correction if required
Here is the mxml code :
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"

        <![CDATA[

                channelSet.addChannel(channel);
                srv = new RemoteObject();
                srv.destination="runtime-policy";
                srv.channelSet = channelSet;
                srv.PolicyApnVO.getPoliciesApn();
        ]]>
    </mx:Script>
    <mx:Panel title="Policy Details" width="100%" height="100%">

            </mx:columns>
        </mx:DataGrid>
    </mx:Panel>
</mx:Application>

There may be other ways to do this but here's what I would do:
1) add a results method to the remote object:
src.result="onResult(event.result)";
2) add the callback method: private function onResult(event : * = null)
:void{
                                                     if(event is
ArrayCollection)
                                                            myData =
ArrayCollection(event);
3) add the variable: private var myData:ArrayCollection;
4) make the dataProvider for the grid use the my data :
dataProvider=""
You can probably avoid all this by adjusting your dataProvider. I am just
not sure what it would be without experimenting. But definitely not what
you have. Maybe just {svc.result}.

How to pass a result set as an output parameter

I have a function that will be used as a web service. It invokes a stored procedure - ideally I'd like to pass the result set from the SP out as a result set to the client consuming the web service. Is this do-able or am I in dreamland?

What you typically do is iterate thru the RS, turning each row of data into a business object and adding all the business objects to a list or some other collection. Then close the result set. Return that collection of business objects to the client.

How to hold the result set

     We have a GUI swing screen in which we have navigation buttons.
     when the user clicks the previous ,next, last,first buttons we have to show the records accordingly.
     The min. size of the database is around 1 million.and each row has 60 columns.
     Our approach is screen--->servlet-->ejb beans --->database.
     since the database is huge how to hold the values, and where, without affecting the performance.
     If we get the resultset it holds all the data.since the data size is huge,we are looking for a solution.The user may browse through the data ,edit the data and delete the data.
     we have to perform accordingly. Also, if, for example, user1 is seeing record no.1 & user 2 has modified record no.3 in the meanwhile, when user1 goes to record no.3, he should see the
     modified record. In short, the user should always see the latest values.
     please give us the best approach to solve this problem.
Also this is in a multi user environment.

It seems like you need to look at threads to update current values in the display and narrow the result set that you retrieve to match the criteria needed for display. You might consider making the method to change values a syncronized one.

Can we pass temporary result set to the procedure?

Hi,
The result set is stored in a temporary storage. Can we pass that resultset to the procedure?
Thanks and regards
Gowtham Sen.

I'm still unclear just what this result set is... Is is a table or a cursor or something else?
If you imply the physical result set of a SQL query, there is no such thing in Oracle. Oracle does not create and store a result set in memory containing the rows of the SQL SELECT. Creating such sets in memory does not scale. A single SELECT on such a database can kill the performance of the entire database by exhasuting all memory with a single large physical result set.
Oracle "results" live in the database cache (residing in the SGA). Rows (as data blocks) are paged into and out of this case as demand dictates. When PL/SQL code, for example, fetches a row, the SQL engine grabs the row from the db cache (SGA) and copies it to the PGA (the private memory area of the PL/SQL process). The row also may not yet exist in the db cache - in which case it needs a physical read from disk to get the data block containing that row into the db cache (after which it is copied to the PGA).
A PL/SQL process can do a bulk fetch - e.g. fetch a 100 rows from the SQL query/cursor at a time. In that case, a 100 rows are copied from the SGA db cache to the PGA.
At no time is there are single large unique and dedicated memory struct in the SGA that contains the complete "result set" of a SQL query.
Once you have fetched that row, that is it. Deal is done. You cannot reverse the cursor and fetch the row again. After you have fetched the last row in that cursor, you cannot pass that cursor to another process - the cursor is now empty. That other process cannot rewind the cursor and start fetching from the 1st row again. You will need to pass the SQL to that process in order for it to create its own cursor - also keeping in mind that in between the rows can have changed and that this other process could now see different results with its cursor.
If you want to create such a physical temporary result set that is consistent and re-usable, you can use a temporary table - and insert the results of the SELECT into this temp table for further processing. This temp table is session specific and is auto destroyed when the session terminates.
A comment though - it sounds like you're approaching the date warehouse processing (scrubbing, transformation and loading of data) as a row-by-row process.
That is a flawed approach. Row-by-row processing does not scale. One should deal with data sets. Especially when the volumes are large. One should also attempt to perform minimal passes through a data set. Processing a bunch of rows, then passing that rows to another process to do some processing on the same rows.. this means multiple passes through the same data. That is very inefficient performance and resource wise.

How do I create a 1d array that takes a single calculation and insert the result into the first row and then the next calculation the next time the loop passes that point and puts the results in thsecond row and so on until the loop is exited.

The attached file is work inprogress, with some dummy data sp that I can test it out without having to connect to equipment.
The second tab is the one that I am having the problem with. the output array from the replace element appears to be starting at the index position of 1 rather than 0 but that is ok it is still show that the new data is placed in incrementing element locations. However the main array that I am trying to build that is suppose to take each new calculation and place it in the next index(row) does not ap
pear to be working or at least I am not getting any indication on the inidcator.
Basically what I am attempting to do is is gather some pulses from adevice for a minute, place the results for a calculation, so that it displays then do the same again the next minute, but put these result in the next row and so on until the specifiied time has expired and the loop exits. I need to have all results displayed and keep building the array(display until, the end of the test)Eventually I will have to include a min max section that displays the min and max values calculated, but that should be easy with the min max function.Actually I thought this should have been easy but, I gues I can not see the forest through the trees. Can any one help to slear this up for me.

I didn't really have time to dig in and understand your program in depth,
but I have a few tips for you that might things a bit easier:
- You use local variables excessively which really complicates things. Try
not to use them and it will make your life easier.
- If you flowchart the design (very similar to a dataflow diagram, keep in
mind!) you want to gather data, calculate a value from that data, store the
calculation in an array, and loop while the time is in a certain range. So
theres really not much need for a sequence as long as you get rid of the
local variables (sequences also complicate things)
- You loop again if timepassed+1 is still less than some constant. Rather
than messing with locals it seems so much easier to use a shiftregister (if
absolutely necessary) or in this case base it upon the number of iterations
of the loop. In this case it looks like "time passed" is the same thing as
the number of loop iterations, but I didn't check closely. There's an i
terminal in your whileloop to read for the number of iterations.
- After having simplified your design by eliminating unnecessary sequence
and local variables, you should be able to draw out the labview diagram.
Don't try to use the "insert into array" vis since theres no need. Each
iteration of your loop calculates a number which goes into the next position
of the array right? Pass your result outside the loop, and enable indexing
on the terminal so Labview automatically generates the array for you. If
your calculation is a function of previous data, then use a shift register
to keep previous values around.
I wish you luck. Post again if you have any questions. Without a more
detailed understanding of your task at hand it's kind of hard to post actual
code suggestions for you.

Why to need close the result set and statement

why to need close the result set and statement

It's best to explicitly close every ResultSet, Statement, and Connection in the narrowest scope possible.
These should be closed in a finally block.
Since each close() method throws SQLException, each one should be in an individual try/catch block to ensure that a failure to close one won't ruin the chances for all the others.
You can capture this in one nice utility class, like this:

Captivate is not really designed to do what you want in this instance. It's more targeted at allowing a user to complete an assessment and then track whether or not they passed. So it's only really set up to send information in a format that the LMS will understand and interpret as Pass/Faill and what the score was.
You really need something more flexible than that. So I think you would need to get a programmer involved and have the solution custom made. In my experience, any time you try to diverge Captivate from what it was designed to do, and you need to get other IT professionals involved, you can kiss thousands of dollars goodbye before you have a workable solution.

Execute a VO '4' times and show the result in single table at once.

Hi,
I want to execute single a VO query multiple times with different parameters and show the results together in a Table at once
In Detail
I have a table to which is associated with a VO.
The VO contains SQL whose WhereClauseParameters need to be dynamically binded.say headerId and lineId
Select ... from ....where headerId = :1 AND lineId = :2
I have to pass these 4 values and show all the results in a single table
headerId lineid
H1 ............... L1
H1 ............... L2
H2 ............... L1
H2 ............... L2
I understand that i need to bind parameters dynamically and exceute the VO.
As i have 4 different set of parameters, the view object will be executed 4 times.
I want to show all the results together in a single table.
How can I do it.
thanks,
Gowtam

Hi Mani,
Thanks a lot for the patience and detailed solution.I will try it out and tell you the status.
Meanwhile, I have 2 questions on this solution(just curious)
I will give you the snapshot of the table
Table - ModelInfo
Model......Tube..... Float....Size......Col5.....Col6.......Col7.......
M1............T1.......... F1. .....1..........C15......C16.....C17.....
M1............T1...........F1.......2..........C25......C26.....C27.....
M1............T2......... .F2.......1..........C35......C36.....C37.....
M1............T2...........F2.......2..........C45......C46.....C47.....
M2............T1.......... F1. .....1..........
M2.............T1..........F1.....2.........Cn5.......Cn6........Cn7
.<continues...>
.<till>
.Mn............Tn..........Fn.......n........Cxy.......Cpq.......Crs....
Question 1:
if you notice this data,
The Columns 5 to 7 are dependent on Combination of Model,Tube,Float and Size.
Hence will this query work properly(without mixing up data from other Pk combination) and will it be efficient?(I Know this is a stupid qst, still double checking..As your solution assumes that each row is unique for Model only..which is not true)
Select ...From....Where
Model in(M1,M2,..Mn) AND Tube in(T1,T2..Tn) AND Float in(F1,F2,....Fn) and Size in(1,2...n).
In short, will C15,C16 and C17 appear only with M1,T1,F1,1..I believe it will.
Question 2:
As I told,
Third party program will return Array of Objects.
Each object will have a variable called Flow along with
Model,Tube,Float and Size.
Flow is not stored in the database(can not be stored due to functional reasons).I want to show this Flow also along with other columns fetched from the DB for all 100+ rows.
How can I do it?
I will give u the scenario(with just 2 rows)...please check(Flow is not stored in DB)
Third Party object : ObjModel
Model......Tube..... Float....Size......Flow
M1............T1.......... F1. .....1..........100
M1............T1...........F2.......2...........200.
M1............T2.......... F1.......1..........300
M1............T2...........F2.......2..........400
My concern is,
After the VO executes and shows other 6 columns, it should show Flow appropriately.(associated with each object in the array)
I understand that I need to have a Transient attribute in VO called[b] Flow.But I don't know how to perform the two tasks simultaneously..
Task1:Your solution on showing table columns
Task2:Showing Transient data for each object returned from program.
thanks,
Gowtam

JdbcodbcDriver uses the wrong charSet for interpreting the result set data

Hi everyone,
I?m having trouble getting results from a MS Access database which uses Greek characters. All the characters in the range 0-127 are returned good but I get ??? for all above 127.
Here is some more details:
OS: win2k
Local setting for current user: Greek (not that it makes a difference)
Default Language setting for the System: English (Astralia). This uses charSet Cp1252 or ISO 8859-1 encoding.
Environment: JBuilder 7.0
JDK: 1.4.1
DB: MS Access
DB charSet: Cp1253 (Greek encoding or ISO 8859-7)
Connection method:
     java.util.Properties prop = new java.util.Properties();
     prop.put("user" , userName);
     prop.put("password" , password);
     //driver is "sun.jdbc.odbc.JdbcOdbcDriver";
     //none of these work
     //prop.put("charSet", "UTF-8");
     //prop.put("charSet", "Greek");
     prop.put("charSet", "Cp1253");
     connection = DriverManager.getConnection(MY_ACCESS_DB,prop);
DataSet Access method:
     // run query and get resultSet rs here
     char[] cBuff= new char[1000];
     // I have tried getString(), getBytes(), getBinaryStream also
     Reader rReader = rs.getCharacterStream(3);
     BufferedReader fIn = new BufferedReader(rReader);
     int res = fIn.read(cBuff, 0, 999);
     // contents of cBuff is incorrect here
I have also used -Dfile.encoding=Cp1253 in command line which seems to change the default charSet of the JVM. Tested
     String en = new InputStreamReader(System.in).getEncoding();
     System.out.println("Default encoding: " + en);
By enabling trace and looking at the content of the resultSet object it shows that
rs.OdbcApi.charSet = "Cp1253"
So I'm absolutely stumped. The only possible problems I can think of is either a bug in the jdbcodbcDriver or in my native ODBC driver. The latter is less likely since I connected to the same datasouce using a different application and get the right result.
One more thing that may be helpful, if I set up the default charSet under Win2K to "Greek" (that is setting default language setting in Regional Options under Control Panel)
Everything works fine.
Is there anyone out there with answer to my problem?
Thanks in advance.

Tried your program and it does exactly as I expected. I get a whole lot of '?'s with my OS default language setting on English but it works fine as soon as I set it to Greek. It does not make a difference if I change the "input language" on the language bar (shift+ctrl) to Greek or not. Or if I change the charSet in your program to something else. Which bring up the question what do you use the charSet setting on your program for? If it is for byte conversion, I don't think you need it since the OS default charset is used by ResultSet.GetString and that needs to be set anyway.
Anyhow your program basically behaves exactly the same way as mine does. I am almost 100% sure that the problem is with the properties used (or not used) when creating the connections. There has got to be a (provider) property like "useUnicode" or "charSet" or something that is passed through jdbcodbc bridge to ODBC to MS Access to force it to return the result set in UTF-8 format. I confirmed this by using Visual C++ data access program that i wrote (which has the same sort of problem). All other MS Office products know about this property that why they work when i imort data from them.
This means I don't have a jdbc or even a java problem but my problem is MS Access related. So I�m going to post a question on an MS Access user group (if I find one) and see what I get). Thanks for your help with this.
By the way AOKabc crashed once and froze another time. I think it had more to do with the libraries you are using rather than your code. I have a trace log if you are interested.

How to exclude the XML declaration from each row of the result set?

Hi,
I have a table with an XMLTYPE column and would like to SELECT a set of rows. How can I exclude the XML declaration from each row in the result set? My query currently looks like this, I'm executing it through Spring JDBC:
SELECT XMLSerialize(CONTENT t1.xmltext) FROM myschema.event t1 WHERE XMLEXISTS('$e/Event' PASSING XMLTEXT AS "e") ORDER BY t1.time DESC
After selecting, in my application I convert each row into a String and concatenate all rows into one big string in order to parse it into a DOM model. I get a parser exception (org.xml.sax.SAXParseException: The processing instruction target matching "[xX][mM][lL]" is not allowed) because there are multiple XML declarations in my big string. Of course, I could manually check the String of each row whether it starts with the XML declaration, but it would be nicer if I could instruct the DB not to add it in the first place. Is there a way?
Thanks!

Hi,
A couple of options I can think of :
SELECT XMLSerialize(CONTENT
XMLtransform(t1.xmltext,
xmltype('<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes"/>
<xsl:template match="/"><xsl:copy-of select="*"/></xsl:template>
</xsl:stylesheet>')
FROM myschema.event t1
WHERE XMLEXISTS('$e/Event' PASSING XMLTEXT AS "e")
ORDER BY t1.time DESC
;or simply,
SELECT XMLSerialize(CONTENT
extract(t1.xmltext,'/')
FROM myschema.event t1
WHERE XMLEXISTS('$e/Event' PASSING XMLTEXT AS "e")
ORDER BY t1.time DESC
;

How to send email using pl/sql containing the result set as the msg body

Hi.. im using Pl/SQL code to send emails to the users from a dataset that is obtained in a databse table. i have used utl_smtp commands to establish the connection with the smtp mail server. im stuck at the logic when i have to include the message body which is actually the result set of a table.. For instance
IF (p_message = 0) THEN
UTL_SMTP.write_data(l_mail_conn, 'There is no mismatch between the codes' || UTL_TCP.crlf);
ELSE
UTL_SMTP.write_data(l_mail_conn, 'The missing codes are ' || UTL_TCP.crlf);
for s in (select * from temp)
loop
UTL_SMTP.write_data(l_mail_conn, ' ' ||s || UTL_TCP.crlf);
end loop;
END IF;
UTL_SMTP.close_data(l_mail_conn);
UTL_SMTP.quit(l_mail_conn);
END;
***p_message is a prameter passed to this procedure..
Can i obtain the result in the form i have it in my table. which has three columns. I want to display the three columns as it is with teh records. ?

this is not related about this forum but you can use below,
CREATE OR REPLACE PROCEDURE SEND_MAIL (subject varchar2,mail_from varchar2, mail_to varchar2,mail_msg varchar2)
IS
mail_host varchar2(30):='XXXXX';
mail_conn utl_smtp.connection;
tz_offset number:=0;
str varchar2(32000);
BEGIN
begin
select to_number(replace(dbtimezone,':00'))/24 into tz_offset from dual;
exception
when others then
null;
end;
mail_conn:=utl_smtp.open_connection(mail_host, 25);
utl_smtp.helo(mail_conn,mail_host);
utl_smtp.mail(mail_conn,'[email protected]');
utl_smtp.rcpt(mail_conn,mail_to);
utl_smtp.open_data(mail_conn);
utl_smtp.write_data(mail_conn,'Date: '||to_char(sysdate-tz_offset,'dd mon yy hh24:mi:ss')||utl_tcp.crlf);
utl_smtp.write_data(mail_conn,'From: '|| mail_from ||utl_tcp.crlf);
utl_smtp.write_data(mail_conn,'To: "'|| mail_to ||'" <'||mail_to||'>'||utl_tcp.crlf);
utl_smtp.write_data(mail_conn,'Subject: '||subject||utl_tcp.crlf);
utl_smtp.write_data(mail_conn,utl_tcp.crlf);
utl_smtp.write_data(mail_conn,replace_turkish_chars(mail_msg)||utl_tcp.crlf);
utl_smtp.write_data(mail_conn,utl_tcp.crlf);
utl_smtp.close_data(mail_conn);
utl_smtp.quit(mail_conn);
END;

Creating remote objects and passing the retrieved data to modules

I found at this Adobe tutorial a nice "RemoteService" class that creates a RemoteObject and contains the functions for handling the result and fault events. If I wanted to use this approach, how could I pass the data from the result handler to interfaces that modules from the main application could use?
I could put the RemoteService/RemoteObject in the modules, but (in my opinion- and I could be wrong) the best design seems to be using the remote calls in the main app and passing the data along to the modules.
Ultimately, I would like to know what the "best practices" are for creating remote objects and passing the retrieved data to modules
Thanks!

public void mouseClicked(MouseEvent e) {
X x = new X(e.getX(), e.getY());
}I don't see the difficulty.
