Writing the Result set to a file!

Hello ...java gurus.. pls i want to write the contents of my result set to a file ...i have tried it but when i open the files it contains jargons any other way?
thanks.

Just get the results as strings, ints or whatever you want and write them. If you want, store results in vectors, hashes... and write the file after closing connections.

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.

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.

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:

Exporting query result set into CSV file using Forms

Hi ,
My requirement is
-> I need to create a form where I have a Multi line text box and two button.
-> When I enter a query in text box and click on Execute button, It should execute a select query.
-> After execution, Result set needs to be exported into an Excel file.
Please give a hint how to do this????
Thanks,
maddy

as you are using text item to write SQL query by the user
so for that you need to use the exec_sql package to parse the text items query and get definitions and values of the columns being
resulted in the result set of the query.
once your query is execute to the desired connection then you need to use fetch the result to the CSV file by use of the TEXT_io package
which will open the text file with .csv extension and you have to pass the each line to that text file with comma separated values as "ss","rr" etc.
or you can use the ole2 package to call the excel application and then fetch the data of exe_sql query to that.

It is required to get the result set from the last query.

I need this SP to return the result set from the last query.

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules (you have no idea).
Temporal data should use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
What you did post is bad SQL.
The prefix “tbl-” is a design flaw called tibbling and we do not do it. We seldom use temp tables in RDBMS; it is how magnetic tape file programmers fake scratch tapes.
If the schema is correct, then SELECT DISTINCT is almost never used.
Your “bill_parent” looks like a assembly language bit flag; we never use those flags in SQL.
“Funding_Type_Status” is an absurd name for a table. A status is a state of being, not an entity. A type is an attribute property. So this table ought to be column that is either a “funding_type” or “funding_status” (with the time period for the state of being
shown in other columns). But this hybrid is not possible in a valid data model.
Want to try again, with DDL and some specs?

OBIEE Answers does not display the result set of a report query

Hi,
We have a pivot table type of report in Oracle Business Intelligence Enterprise Edition v.10.1.3.3.2 Answers that has the following characteristics:
     3 Pages
     3 Sections , 4 Columns
     18363 Rows in the result set
As per the NQQuery.log, the query for this report executes successfully resulting in 18363 rows. However, nothing comes up in the display on Answers. Moreover, no error is reported. The instanceconfig.xml file has the following setting:
<PivotView>
     <CubeMaxRecords>30000</CubeMaxRecords>
     <CubeMaxPopulatedCells>300000</CubeMaxPopulatedCells>
</PivotView>
Even with these settings, Answers just returns a blank page - nothing is displayed in the name of the result set of the report query. Has anyone encountered this problem scenario before?
Any help is much appreciated.
Thanks,
Piyush

Hi Fiston / Pradeep,
Thanks for your inputs. A few points to note:
-> I am actually not getting any error message in answers or the NQQuery log. Moreover I am not getting any errors related to "query governor limit exceeding in cube generation" also.
-> I have other pivot table type of reports in the same repository that work fine. In fact the report which has this issue even works sometimes - what actually is happening is that if I alter the number of sections from 3 to 4, then the result set changes from 14755 Rows to 18363 Rows and as per the NQQuery.log in both cases the query completes successfully. However, when the result set has 14755 rows, I get to see the output in Answers; however when the result set is 18636 rows, the Answers screen just goes blank and does not show any output or error. This makes me believe that there is some parameter in instanceconfig or the NQSconfig file - I have tried a lot of changes but nothing works !
Any help is much appreciated.
Best Regards,
Piyush

RIDC api: The result set 'content' was not found or is empty

Hi,
I am trying to add a revision using COLLECTION_CHECKIN_REVISION. The content which I want to add a revision has only one revision i.e. 1,
and its dID is 3746 and is already checked out.
<code>
     binder.putLocal ("IdcService", "COLLECTION_CHECKIN_REVISION");
     // get the binder
     binder.putLocal ("dDocTitle", "Html file");
     binder.putLocal ("dDocName", "SUN00100");
     binder.putLocal ("dDocType", "Document");
     binder.putLocal ("dSecurityGroup", "Public");
     binder.putLocal("hasCollectionID", "true");
     binder.putLocal("dID", "3746");
     binder.putLocal("dRevLabel", "2");
     binder.putLocal("dCollectionID", this.getFolderIdFromPath(idcClient, userContext, PATH));
     System.out.println("dCollectionID###############################" +binder.getLocal("dCollectionID"));
     binder.addFile ("primaryFile", new TransferFile(new File("D:\\P6WS\\RIDC Test\\src\\com\\oracle\\ridc\\poc\\2.html")));
     // checkin the file
     response = idcClient.sendRequest(userContext, binder);
     System.out.println("response "+response.getResponseAsString());
</code>
And the output is as follows

I want to understand which content is being referred. The primaryFile is existing in the same location.
Did I missed out any required parameter.

Like last time: documentation is not a big help here, so you have to do a bit of investigation yourself.
In order to understand result sets, check this link: http://download.oracle.com/docs/cd/E17904_01/doc.1111/e10726/c04_master_usage.htm#CSIDO249
('content' is the name of the result set)
I can't imagine why you would need such a result set while checkin in a new revision to a folder, but the documentation (http://download.oracle.com/docs/cd/E17904_01/doc.1111/e11011/c08_folders.htm#i1082329) advices that some sub services are called, so it might actually be an error coming from these subservices. I'd suggest to narrow down the search first - turn on requestaudit in server-wide tracing (see here: http://download.oracle.com/docs/cd/E17904_01/doc.1111/e10792/c02_processes.htm#CSMSP536).
Alternatively, you could also perform your service call from GUI and trace what parameters are provided. I guess something will be missing.

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,

mail_host varchar2(30):='XXXXX';
mail_conn utl_smtp.connection;

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);

How to add a dummy row in the result set of a SELECT statement.

Hello Everyone -
I have requirment to add a dummy row in the result set of a SELECT statement.
For e.g. lets say there is a table Payment having following colums:
Payment_id number
status varchar2(10)
amount number
payment_date date
so here is the data :-
Payment_id Status Amount payment_date
1 Applied 100 12/07/2008
2 Reversed 200 01/ 06/2009
3 Applied 300 01/ 07/2009
Here is my SQL
Select * form payment where payment_date >= 01/01/2009
Output will be
2 Reversed 200 01/ 06/2009
3 Applied 300 01/ 07/2009
My desired output is below
2 Reversed 200 01/ 06/2009
3 Applied 300 01/ 07/2009
2 Reversed -200 01/ 06/2009 ------(Dummy Row)
Thrid row here is the dummy row which I want to add when status is "Reversed"
I would be very thankful for any kind of help in this regard ...
Thanks,
Gaurav

Cartesion joining against a dummy table is a useful method of creating a dummy row:
with my_tab as (select 1 cust_id, 1 Payment_id, 'Applied' Status, 100 Amount, to_date('12/07/2008', 'mm/dd/yyyy') payment_date from dual union all
                select 1 cust_id, 2 Payment_id, 'Reversed' Status, 200 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 1 cust_id, 3 Payment_id, 'Applied' Status, 300 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 1 Payment_id, 'Applied' Status, 100 Amount, to_date('12/07/2008', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 2 Payment_id, 'Reversed' Status, 200 Amount, to_date('01/05/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 3 Payment_id, 'Applied' Status, 300 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 4 Payment_id, 'Reversed' Status, -400 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 5 Payment_id, 'Applied' Status, 500 Amount, to_date('01/07/2009', 'mm/dd/yyyy') payment_date from dual),
                --- end of mimicking your table
      dummy as (select 'Reversed' col1, 1 rn from dual union all
                select 'Reversed' col1, 2 rn from dual)
select mt.cust_id,
       mt.payment_id,
       mt.status,
       decode(dummy.rn, 2, -1*mt.amount, mt.amount) amount,
       mt.payment_date
from   my_tab mt,
       dummy
where mt.status = dummy.col1 (+)
order by mt.cust_id, mt.payment_id, dummy.rn nulls first;

NB. You may have to mess around with the ordering if that's not come back in the order you wanted. You didn't mention what the rules were for any expected ordering though, so I've made up my own *{;-)
Also, I added an identifier (cust_id) to differentiate between different sets of payments, since that's usually the case. Remove that if it's not applicable for your case.

How to get the result set in batches

I have a query which results into large data. This data i want to display in a group of 20. After every 20 records i want to add header and footer to it.
Is it possible to get the result set data into batch of 20 ? means can i specify start and end index of query ?
regards
Manisha

What I am saying is that a big query with lots of
joins will probably be slow, and as such would be a
ripe candidate for batching the responses, if it were
not possible to speed/optimize it. Batching is nice
to look at for the user, but is not a solution for
performance problems. In essence it is irrelevant
that it adds a little performance deficit, as it
appears to be running a lot quicker, and gives more
feedback to the user.Then let me say it again....
- "Join" is a term that applies to a method of doing queries in the database....
- Query 1 which uses a join and returns 15 rows
- Query 2 which does not use a join and returns 1500 rows.
Given the above then Query 1 will provide better overall performance for the system than Query 2 in a properly configured database.
If it doesn't then the database is not set up correctly.
And again this will be irrespective of whether the query is scrollable or not.

How to return the result set of multiple select statements as one result set?

Hi All,
I have multiple select statements in my stored procedure that I want to return as one result set
for instance
select id from tableA
union
select name from table b
but union will not work because the result sets datatypes are not identical so how to go about this ?
Thanks

You have to CAST or CONVERT (or implicitly convert) the columns to the same datatype. You must find a datatype that both columns can be converted to without error. In your example I'm guessing id is an int and name is a varchar or nvarchar.
Since you didn't convert the datatypes, SQL will use its data precedence rules and attempt to convert name to an int. If any row contains a row that has a value in name that cannot be converted to an int, you will get an error. The solution is
to force SQL to convert the int to varchar. So you want something like
select cast(id as varchar(12)) from tableA
union
select name from tableb
If the datatypes are something other that int or varchar, you must find a compatable datatype and then convert one (or both) of the columns to that datatype.

Statement.close() Not closing the Result set

Hi all,
I have the following code which invokes a procedure in Oracle database
public static callProcedure(Connection connection,String procedure){
ResultSet resultSet = null;
CallableStatement callableStatement = null;
try {
callableStatement = connection.prepareCall(procedure);
callableStatement.registerOutParameter(1,OracleTypes.CURSOR);
callableStatement.execute();
resultSet =((OracleCallableStatement)callableStatement).getCursor(1);
} catch (Exception exception) {
exception.printStackTrace();
} finally {
try {
callableStatement.close();
} catch (SQLException sqlException) {
sqlException.printStackTrace()
return resultSet;
Ideally if i try to iterate through the result set which is returned then it should give me resultset closed as i am closing the resultset. But this is not happening.
Please anybody can explain the isue

Hi,
That is not easy to explain, I might take a guess and say that a statement cache is being used therefore the statement is not actually being closed.
I always close the reultset then the statement so wouldn't notice this behaviour.
Why are you returning a resultset anyway? If you really need to do this I would suggest using a disconnected resultset:
OracleCachedRowSet ocrs = new OracleCachedRowSet();
ocrs.populate(resultSet);
return ocrs;

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,

Restricting the no. of entries in the result set iView

Hi,
Is there a way to restrict the no. of entries in the Result set iView.
Whenever I create a result set iView , it gets loaded with all the entries of the search table it is associated with.
Is there a way to restrict to say 5 or 6 entries.
Best Regards
Sid
