Header text on top of the result set
hi ,
i am working with a query and the users requirement is to see a header value on top of the result.for example i am working with a sales multi provider which gives sales for this year and sales for curent year1,2,+3.soi have 4 key figures (for 4 years). the user wants to see the year on top of the key figure.
in some cases they need to see a standard text on top of 2 key figures.
2005 2006
sales tax sales tax
100$ 10$ 250$ 23$
in this case 2005 and 2006 should be generated
cash budget commitment budget
sales projected sales sales projected sales
100 150 159 200
in this case cash budget and commitment budget are constants.
i am concerned how we can acheive the values 2005 and 2006 and standarsd texts cash budget and commitment budget.
thanks in advance
sri
You need to create text Variables for each column(KF).
Right Click / Edit on key figure / beside description choose text variables / create a text variable from calendar year field if you using restricted key figures as they restricted on calendar year.
If you have 4 basic key figures for 4 years , you may have to write ABAP for this using customer Exit.
Cheers

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. -
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
ManishaWhat 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. -
Saving the result set in a Search page
Hi ,
We have a manual search page where the results are displayed in the form of 10 columns. The first 5 are read only fields whereas rest 5 are editable checkboxes.
There is no Query region created in our page.
Suppose, fields a, b, c are search parameters and the results are as :
| A | B | C| D |E | F | G | H | I | J |
1
2
3
4
5
6
7
7 records are retrieved. Columns A to E are read only text fields whereas columns F to J are check boxes. The user can update the checkboxes. We have a Save button below the result set region. This button on being pressed invokes a stored PL/SQL Procedure which does some validations on the result set so obtained.
Our requirement is to dump all the 7 records (after the modifications are made to any number of result records) into a temporary table . The procedure will then pick the records from this temporary table and do the required validations.
Question is :
1. How to store the result set so obtained into a table after some (or all) records are modified once Save is pressed ?
We do not have any EO created in our page. The VO for obtaining the Result set is a combination of many tables.
Any help would be greatly appreciated.
Thanks,

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,
GauravCartesion 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 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 ?
ThanksYou 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 isueHi,
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

Megastar_ChiruI 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

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.

Getting message : The result set for this selection was empty on sm20
Hi,
I assigned below parameters in rz10 :
rsau/user_selection 1
rsau/max_diskspace/per_day 1950M
rsau/max_diskspace/per_file 650M
rsau/enable 1
I activated security audit profile in sm19 also.But when iam going to sm20 for analysis of security audit log iam not getting report iam getting this message : The result set for this selection was empty.
Gudie me for the same.
ThankuHi,
The result set for this selection was empty.
I think your configuration is OK except one thing...
Check in SM19, if you have selected "Filter Active" check box in "Filter 1 and Filter 2" screen and Also "Audit Classess".
Even though security audit is enabled in SM19, without selecting filter it will not log the events and give you the above message.

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.

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:

}Anybody who lets the GC or timeouts or sheer luck handle their resource recovery for them is a hack and gets what they deserve.
Do a search on problems with Oracle cursors being exhausted and learn what the root cause is. That should convince you.

Gor The result set is closed after switch to latest microsoft JDBC driver
The same code works fine with the previous version of the microsoft JDBC driver, but throws
com.microsoft.sqlserver.jdbc.SQLServerException: The result set is closed.
for the JDBC driver 4.
Please Help!
Thanks.I found the same exception when dealing with ResultSetMetaData.
Using the old driver (1.2.2828.100) it was possible to do something like:
Statement s = con.createStatement();
ResultSet r = s.executeQuery("select * from <table>");
ResultSetMetaData m = r.getMetaData();
r.close();
s.close();
int numCols = m.getColumnCount();
But using the new driver (2.0.1803.100) it complains that the result set is closed.
The solution was to keep the ResultSet and Statement open until after the ResultSetMetaData is no longer needed. It is somewhat inconvenient because before it was possible to have a utility method that would return a ResultSetMetaData object and not have to worry about keeping the Statement and ResultSet objects around.
I was hoping for a speed increase for batch inserts by having the latest driver, sadly there is no performance gain.
