Convert result of query to CLOB

Hi,
I have a query which is 'execute immediate vc_query into vcl_result'. Here vc_query is a varchar2 which is holding my query and return some value, And vc_result is a CLOB.
Now, this statement is failing to execute and saying inconsistent datatypes.
Is there a way I can convert the result of the sql query in the variable to convert to clob?
Thanks,

Yes and no. It depends.
a) why are you using execute immediate to execute a query?
b) why do you want the results stored in a CLOB?
c) what structure should the results have in the CLOB?
d) read the FAQ: Re: 2. How do I ask a question on the forums? and post sufficient details so people can answer you properly.

Converting Oracle XML Query Result in Java String by using XSU

Hi,
I have a problem by converting Oracle XML Query Result in Java
String by using XSU. I use XSU for Java.
For example:
String datum=new OracleXMLQuery(conn,"Select max(ps.datum) from
preise ps where match='"+args[0]+"'");
String datum1=datum;
I become the following error:
Prototyp.java:47: Incompatible type for declaration. Can't
convert oracle.xml.sql.query.OracleXMLQuery to java.lang.String.
Can somebody tell me a method() for converting to solve my
problem??????
Thanks

Hmmm.. Pretty basic just look at the example:
OracleXMLQuery qry = new OracleXMLQuery(conn,"Select max(ps.datum) from preise ps where match='"+args[0]+"'");
String xmlString = qry.getXMLString();

Issue converting the following query to text.

Hello guys, I'm trying to convert the following query to text and to use PRINT so that it returns theresult in the picture as output, help would be appreciated, thanks :)SELECT EventName, EventDate
FROM EventTable
ORDER BY EventDate DESC;

This is an example, As I said it is not a good approach
set nocount on
declare @tab table(id int,txt varchar(100));
declare @txt varchar(1000);
declare @count int;
insert into @tab
values(1,'Text 1'),(2,'Text 2'),(4,'Text 4');
select *,RN=ROW_NUMBER()OVER(ORDER BY (SELECT NULL)) into #temp from @tab
select @count=@@ROWCOUNT;
while @count>0
begin
select @txt =right(replicate(' ',50)+convert(varchar(50),ID),50) +
right(replicate(' ',50)+convert(varchar(50),txt),50)
from #temp where RN=@count
set @count=@count-1
print @txt
end
drop Table #temp

A way to convert selection from query builder in DML language

I search a way to convert selection from query builder in DML language.

We will make a sample from this request and post it on OTN. I have pasted all the JSP code so you should be able to use it directly. Just change the BISession details and the presentation references.

Inconsistent SDO_RELATE results when querying 2.5D data

Oracle 11.1.0.7 with Patch 8343061 on Windows Server 2003 32bit.
I'm getting inconsistent results from SDO_RELATE results when querying 2.5D data. Some geometries I expect to be OVERLAPBDYDISJOINT, are not always being returned by SDO_RELATE when using the OVERLAPBDYDISJOINT mask. It seems that the order of the tables makes a difference to the result.
Here's a table with one 2.5D geometry and a 2D index:

Query Performance and Result Set Query/Sub-Query

Hi,
I have an infoset with as many as <b>15 joins</b> with different ODS and Master Data..<b>The ODS are quite huge with 20 million, 160 million records)...</b>Its taking a lot of time even for a few days and need to get atleast 3 months data in a reasonable amount of time....
Could anyone please tell me whether <b>Sub-Query or Result Set Query have to be written against the same InfoProvider</b> (Cube, Infoset, etc)...or they can be used in queries
on different infoprovider...
Please suggest...Thanks in Advance.
Regards
Anil

Hi Bhanu,
Needed some help defining the Precalculated Value Set as I wasnt succesful....
Please suggest answers if possible for the questions below
1) Can I use Filter Criteria for restricting the value set for the characteristic when I Define a Query on an ODS. When i tried this it gave me errors as below ..
"System error in program CL_RSR_REQUEST and form EXECUTE_VTABLE:COB_PRO_GET_ALWAYS.... Error when filling value set DELIVERY..
Job cancelled after system exception ERROR_MESSAGE"
2) Can I create a create a Value Set predefined on an Infoset - Not Succesful as Infoset have names such as "InfosetName_F000232" and cannot find the characteristic in Paramter Tab for Value Set in Reprting Agent.
3) How does the precalculated value Set variable help if I am not using any Filtering Criteria and is storing the List of all values for the Variable from the ODS which consists of 20 millio records.
Thanks for your help.
Kind Regards
Anil

Query SQ02 : restriction lines result of query

Hi everybody,
I have prb with a query. I have created a query and infoset. I have join tables .. and I would like to add condition of clause 'where' to restrict the result of query depending on the dates. Those dates are not given in the selection screen but depends on the results of a one table included in infoset.
somebody has idea ?
Thanks.
Maya

Hi,
In the infoset you can write code to restrict the lines..
GO to the infoset in change mode..
click the extras button..
click the code tab..
choose the code section.."Records processing"
In that you will have the table structures available...use the check statement to filter the data..
Ex..
CHECK VBAK-ERDAT = SY-DATUM.
Thanks

Saving result from query into CSV file

Hi folks,
in our application we're generating pages source using general packages (like htp, owa_util, ...). and in this part I'm a really beginner.
I want to modify source one of our page, I want to add functionality to enable save result from query (cursor) into CSV file, to enable user choose place where generated file will be created and also change file name.
I searched this forum and I found procedure, that could be useful:
procedure p_getcsv is
cursor cur is
       select 'a1' col1, 'b1' col2, 'c1' col3 from dual
   union select 'a2' col1, 'b2' col2, 'c2' col3 from dual
   union select 'a3' col1, 'b3' col2, 'c3' col3 from dual;
   begin
        -- Set the MIME type
        owa_util.mime_header( 'application/octet', FALSE );
        -- Set the name of the file
        htp.p('Content-Disposition: attachment; filename="test.csv"');
        -- Close the HTTP Header
        owa_util.http_header_close;
        -- Loop through all rows in EMP
        for x in cur
        loop
            -- Print out a portion of a row,
            -- separated by commas and ended by a CR
             htp.prn(x.col1||','|| x.col2||','||x.col3|| chr(13));
        end loop;
   end;What peace of code should I add to procedure that is generating web page to enable calling this procedure and whole saving process?
Can anybody help me with this?
Many thanks,
Tomas

WEBI Sample Result Set Query Property Question

Wnen I set the WEBI Sample Result Set query property my retrievals took longer than I thought they should especially with a limited result set. When I hit the View SQL button and look at SQL I notice that the following order by is added to the query:
Order by dbms_random.value
I copied the query and ran it against our Oracle database with and without the order by. Without the order by the query ran significantly faster. Is there any way to stop the order by from being generated when the Sample Result Set property is set?
Thanks,
Bob

Thanks for your reply.
I tried to locate the parameter you mentioned in the parameters for my universe and did not find anything referencing not enforcing order bys. I checked the documentation and did not see anything there either. Please respond with the exact name of the parameter or if it is a custom parameter the settings you used to create it.
Thanks,
Bob

Convert to SQL Query

Hi
On a report there is a function "Convert to SQL Query", I have tryed the function and get the SQL statment for the report, is it the only thing to get in "text" instead of the more "graphic" way to show it?
Best Regrads
Jesper Vels

Jesper,
is it the only thing to get in "text" This is correct.The "Convert to SQL Query" link is available for report that are built using the Wizard. Selecting this will give you the underlying SQL Query that you can edit/modify if required.
more "graphic" way to show itWhat do you mean by this? Please elaborate?

Convert result set into input stream

Hi,
I have result set with me having 93 columns with 1 lac rows. I want to download the result set as xls file.
Because of the data set size is large, i'm not able to hold the data in java object. So i'm trying to convert result set to input stream and giving this input stream to servlet output stream by specifying the contentType as text/xls.
I'm not able to convert result set into input stream.
Could you provide a solution here...
Thanks,
Rajesh

1 - JDBC is the wrong way to extract this data. It's like "What's the fastest way
to copy the Oxford English Dictionary using tweets?" I would research the
DBMS's bulk extract functionality.
2 - Are you dead-set absolutely sure you need to do this at all? What can you
do with the data all in one flat file that you cannot do with SQL access to the
data?
3 - If you want to convert all the columns into one (not that it's a huge
win or anything), you can use the DBMS's conversion and concatenation
functionality in your SQL. So instead of
"select col1, col2, col3, .... from MyBigTable"
do (change this to whatever conversion function syntax and concat syntax your DBMS needs)
"select convert(col1, varchar) concat ' ' concat convert(col2, varchar) concat ' ' concat convert(col3, varchar) ... from MyBigTable"
so the result set you get is a single column.

Help with Converting an Access query

Hello:
First time poster and would appreciate some help in converting this Access query into T-SQL so I can use in a Stored Procedure. I don't need help in resolving the syntax for the variables as parameter in the second query, but stuck in writing the first query
in T-SQL . I assume I need some type of nested query with a left join to another query in T-SQL.
How do I convert this from Access into MS-SQL
SELECT TBL_MONTH.L_Month, TBL_MONTH.L_MonthName
FROM TBL_MONTH LEFT JOIN qry_MonthCheck ON TBL_MONTH.L_Month = qry_MonthCheck.L_Month
WHERE (((qry_MonthCheck.L_Month) Is Null));
qryMonthCheck in Access is defined as
SELECT TBL_MONTH.L_Month, TBL_SIGNOFF.SO_YEAR, TBL_SIGNOFF.SO_USER, TBL_SIGNOFF.SO_LOCATION
FROM TBL_MONTH RIGHT JOIN TBL_SIGNOFF ON TBL_MONTH.L_Month = TBL_SIGNOFF.SO_MONTH
WHERE (((TBL_SIGNOFF.SO_YEAR)=[forms]![frm_signoff]![cboyear]) AND ((TBL_SIGNOFF.SO_LOCATION)=[Tempvars]![tmpVarUserLOC]));

It is very much up to personal taste. For tables I use no prefix at all. Or suffix. I prefer plural: categories, products, etc. For junction tables, I drop the plural in the first entity, for instance productcategories. As for the case, many people prefer
initial uppercase, while I go for lowercase only. But initial uppercase has its points, particularly in documentation. I am a staunch advocate of using case-sensitive collation for metadata. I don't see any point in mixing productcategories, Productcategories,
ProductCategories etc. That can only cause confusion.
As for either entities, I don't use views much, and I don't have any prefix for these either. In fact, several views I've been involved used to be tables once upon a time.
If you want to add a marker to the object name, I recommend using a suffix. It is much easier to find objects in the version control system and other browser, when not everything is cluttered on the same letter. For instance, I typically add _sp at the end
of stored procedure names.
