Query results: which kind of datatype?

Hi to all,
I have a query which returns more more more records. I must insert this records in a string that i have to return from a function ( i have to invoke this procedure from an application visual basic 6).
What kind of datatype i have to use? Long datatype is small for me (and for my demand i cannot use clob).
Maybe i could return from a function (for example) a string that is concatenation of more than 2 long datatype! But could i do this? And, if yes, how could i declare my procedure (or function)?
Thanks

This is my code:
declare

risultati:='';

if bilancio_def_entry.codicepool is null then
bilancio_def_entry.codicepool := bilancio_def_entry.codicefisico;

Pl sql variable is risultati (it is a long type).
In the previous code i insert it in a table (but only to see what is results of concatenation ...it's not my purpose). When i insert this code in a procedure i want return from the procedure pl sql the variable risultati+. If risultati is longer than 32k i obtain an error. How could i do to obtain at the end a variable (or a concatenation of variables) long (for example) 2.000.000 of characters? This variable is the return variable of a procedure pl sql.
Thanks a lot.

Hi mujb,
Per my understanding you are using the report builder 3.0 to design the report and when you click the query designer button to execute the query you got the error message above, right?
I have tested on my local envornment and your issue can be caused by the user "SQLServer2014\Mubs" and "mujb-HP\mujb" haven't grant permission to the report server or the shared dataeource/dataset if you have used this.
I would like to confirm if you have assigned both the Item-Level and System-Level role of the user above to sucessfully access the report server, If you haven't grant any access to the above user and when you connect to the report server in the report builder,
you may got the error message:

What does "*" mean in my query result?

Hello all,
I met a problem in my query result which was some of cells in one KF column didn't display the amount but instead with * . Could anybody tell me what the wrong was?
thanks
Ryan

Hi Ryan,
This normally happens when the key figures refers to a unit / currency and the units and currencies are different for different records in the result set of the query.
BEx couldn't sum amounts with different currency or value with different unit. hence you get a '*'. However if you put your cursor on the cell then you can actually see total amount in the cell value at the top header of the excel.
Hope it helps.
Thanks
Soumya

How to upload the web query result to CSV/Text file

Hi,
Kindly help me on the following.
1)       I have info-provider (IP), which has info-objects "company code" and "supplier".
2)       I built a query by putting company-code with a variable in free-charateristics and supplier-code in row.
3)       When I run this query, it will ask company-code as input and the result will be filtered using company-code.
4)       For this query, I created a web-template and assigned data-provider to display the data on the web.
5)       The user wants to enter input company-code='1000' and write the data in a CSV file in a specific directory. i.e, by clicking the execute button (after entering company code) , the result should go to the CSV or text file. i.e. the application should automatically generate the file with query results.
Note: The user should not use context menu to EXPORT TO CSV OR EXCEL file.
Please let me know, if there is any tutorial. Thanks a lot advance help.
Regards
Kandasamy

1. SELECT INTO
Below method will create table when data is inserted from one table to another table. Its useful when you need exactly same datatype as source table.
Use AdventureWorks2008R2;
Go
---Insert data using SELECT INTO
SELECT AddressLine1, City
INTO BothellAddresses
FROM Person.Address
where City = 'Bothell';
GO
---VERIFY DATA
Select AddressLine1, City
FROM BothellAddresses
---DROP TABLE
DROP TABLE BothellAddresses
GO
2. INSERT INTO SELECT
Below method will need table to be created prior to inserting data. Its really useful when table is already created and you want insert data from
another table.
Use AdventureWorks2008R2;
Go
---Create Table
CREATE TABLE BothellAddresses (AddressLine1 NVARCHAR(60), City NVARCHAR(30))
---Insert into above table using SELECT
INSERT INTO BothellAddresses(AddressLine1, City)
SELECT AddressLine1, City
FROM Person.Address
where City = 'Bothell';
---VERIFY DATA
Select AddressLine1, City
FROM BothellAddresses
---DROP TABLE
DROP TABLE BothellAddresses
GO

Query result to ASCII file output

Seems like there SHOULD be some rediculously simple solution
to this - but I sure haven't found it yet! I have a query which
produces the a varying number of columns (based on a multi-select
cfselect) which I need to output to a comma delimited ASCII (.TXT
or .DAT or .CSV file). I have all the steps worked out when the
number of columns and their names are known, but I need to make
this variable. First choice would be to be able to just "DUMP" the
query result into a text file. CFDUMP can send results to a text
file, but NOT in comma delimited format, and with all kinds of info
besides just the basic data. (NOT good!) Second choice, since the
"append to text file" uses an output property that expects a comma
delimited string variable would be to use CFLOOP to loop thru the
rows in the query and put them (a row at a time) into a variable,
then use that variable for the file append. Problem is I can't find
a way to just say "send *ALL* to the string variable. Every example
I have been able to find includes specifying the column NAMES when
doing anything with a row in the query result!!! Short of a brute
force series of if/then statements that specify EACH POSSIBILITY
(in this case 60 - 75 of them, and the number WILL GROW!) I haven't
been able to find a solution. There's GOTTA BE A WAY!!!!! :)

> I tried that, but as far as I could figure you still
have to have a specific column name
Look at the udf more closely. If you read the documentation
it states all of the parameters are optional, except the query. So
if you do not supply column names, the function will use the
columnList variable to determine the names of the columns in the
query. If you look at the actual code, notice it uses array
notation to extract the values (not evaluate) .
... (code to create query) ...

<cfset test = QueryToCSV2( data )>
http://cflib.org/index.cfm?event=page.udfbyid&udfid=1197
> I have a cfselect with multiple set to "yes" and the
selections are "which columns of
> data do you want to see?"
Hopefully you are not using the raw form value directly in
your sql, because that is a sql injection attack just waiting to
happen.

Query resulting Incorrect values

Hello ALL.
I need your suggestions on this issue.
I have a Query on top of multiprovider which is on top of 6 cubes. In the query one RKF is resulting wrong values for Unassigned WBS Element Hierarchy.
RF: Forecast amount
0amount, Version:01, Vtype:20,Company Code:100,Fiscyear=2008 and Posting Period=1-12.
Query resulting: 68,000 and Where as Multi prvider has only 2 rows satisfying the above Restrictions and giving 13,000.
These wrong values are only for Unassgined Nodes of WBS Element.(Rows) Other node values are correct.
I am not sure where it is getting these values?
Kindly suggest.
Thanks,
Geetha


Can you chk if you have the values in the multiprovider?

Optimize query results(timing) returned from custom search query

Casey can you send the following to Oracle Support as soon as you can, we need their input on optimizing returning search results.
To Oracle:
We have noticed in the IdocScript reference guide that there is a way to optimize the query results returning to the user.
Here is the scenario: We have created a custom web query where we send a query to the UCM and return a result using a custom template via url like so
http://dnrucm.dnr.state.la.us/ucm/idcplg?IdcService=GET_SEARCH_RESULTS&QueryText=dDocTitle <matches> `AGREEMENT` <AND> xStateLeaseNum<matches>`00340`&ResultCount=30&SortOrder=Desc&SortField=dInDate&urlTemplate=/ucm/groups/public/documents/oos/hcst-search.hcst
This works fine. The problem is that when a query is broader like
http://dnrucm.dnr.state.la.us/ucm/idcplg?IdcService=GET_SEARCH_RESULTS&QueryText= xStateLeaseNum<matches>`00340`&ResultCount=30&SortOrder=Desc&SortField=dInDate&urlTemplate=/ucm/groups/public/documents/oos/hcst-search.hcst
The query takes an extremely long time to execute and the results template sometimes never comes back, which seems like a timeout.
Is there something else that we can do to optimize the query results?

Hi John,
What version of xMII are you using?
Some things I would try:
1. Clear the Java Web Start Cache - see if that makes any difference.
2. If not, what happens if you save the query under a different name, and then try using it in a new transaction?
3. Please feel free to enter you case into xMII Support via the SAP Support Portal if you are unable to make this work.
Kind Regards,

Hi,
If you are using Bex Query make as work book ,in that you can add charts and save as work book not as a query.
To insert the chart
Go to insert tab in the Excel(Work book) choose which chart you want in that.
After that go the chart which you have selected, right click and go to select data option, choose series for Entries and choose labels for category.
Hope it helps.

Need help on retrieving query result - NPE

Hi, I could get results with the native query in my TOAD, but I can't get it working in my session EJB. I tried both native query and EJB ql. The query created fine, as soon as I try to retrieve results, it gets stuck.
My native query looks like this:
Query query = em.createNativeQuery("select sum(o.amount_reimbursed) from t_expenses o where o.employee_id = '999999911' " +
"and o.EXPENSE_ID in (select p.expense_id from T_Per_Diem_Xref p where p.expense_Type_Xref_Id=22 " +
"and p.expense_Id in (select e.expense_Id from T_Expenses e where e.employee_Id='999999911' " +
"and e.expense_date > to_date('01/01/2011', 'mm/dd/yyyy') and e.expense_date < to_date('12/31/2011', 'mm/dd/yyyy')))") ;
My EJB query looks like this:
Query query = em.createQuery("select sum(o.amountReimbursed) from TExpenses o where o.employeeId = ?1 " +
"and o.expenseId in (select p.expenseId from TPerDiemXref p where p.expenseTypeXrefId=?2 " +
"and p.expenseId in (select e.expenseId from TExpenses e where e.employeeId=?1 and e.expenseDate>=?3 and e.expenseDate<=?4))");
query.setParameter(1, employeeId);
query.setParameter(2, expenseType);
query.setParameter(3, fDay, TemporalType.TIMESTAMP);
query.setParameter(4, lDay, TemporalType.TIMESTAMP);
Either one, I get NPE at the line retrieve result.
// sumAmt = (Double)query.getSingleResult();
List list = query.getResultList();
if (list != null) {
long longAmt = (Long)list.get(0);
sumAmt = (Double)list.get(0);
As you can see, I tried to getSingleResult, or getResultList. also tried to convert the result to Double or Long. None worked.
Please help and thank you for your time.
Sophia

Frank, thank you for your reply. I have this code in my session Facade EJB, and I get the NPE in my backing bean which calls this method. When I debug the code, it appears what really cuases the problem is in this code on the line I try to assign the query result to my variable 'sumAmt = (Double)query.getSingleResult();'. In the debug, when it reaches this line, it starts to give me all kinds of pop-up windows saying couldn't find this file or that file or packages. If I get a stack trace later, I will post it. Right now I am trying to fix something else.
Thanks, Sophia
