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 can i pass second text value to the procedure.

Hi ,
I have used APEX_ITEM.TEXT(1,null) Item_name,APEX_ITEM.TEXT(2,null) file_name in a sql query and i should pass these two text value as a input parameter to the Procedure.
So in Process i have written code like
FOR i IN 1 .. APEX_Application.g_f01.COUNT
LOOP
generate_report_data(APEX_Application.g_f01(i)
,APEX_Application.g_f02(i)
END LOOP;
COMMIT;
if i enter values in two text columns then two values are passing to a procedure it's fine.
Here the issue is if i leave the first value as balnk and enter the 2 nd value like Xyz then click on a submit button
so 2 nd value also passing null to the procedure..
please anybody guide on this issue..
Thanks in advance..

Hello Narender,
>
Here the issue is if i leave the first value as balnk and enter the 2 nd value like Xyz then click on a submit button
so 2 nd value also passing null to the procedure..
>
This is happening because of FOR i IN 1 .. APEX_Application.g_f01.COUNT in your procedure:
>
FOR i IN 1 .. APEX_Application.g_f01.COUNT
LOOP
generate_report_data(APEX_Application.g_f01(i)
,APEX_Application.g_f02(i)
END LOOP;
COMMIT;
>
FOR i IN 1 .. APEX_Application.g_f01.COUNT this loop will take only those values of apex_application.g_f01 into consideration whose value is not null.
Hope it helps!

Loading the different result sets in the same sequence for the target table

Dear all,
I have 5 tables say A,B,C,D as my source and i made 3 joins P,Q,R .the result sets of these 3 joins are loading into a target table X but with 3 different targets with same table name.
I created one sequence say Y as my target table has primary key and mapped to three different targets for the same target table which i need to load.
But after deployed and executed successfully ,i am able to load the data from three join result sets with differeent sequence numbers.
I am looking to load data like this.
If First Result set P has 10 Records,SEcond Result Set Q Has 20 and the third result set has 30 records then while loading data into first target it creates the seq for the 10 records from 1..10 and while loading the data for second result set ,it creates the sequence from 11 ...20 and while loading the third target with the third result set it creates the sequence from 21 ----30.
But i am looking to load the three result sets in the sequence 1to 10 but not like creating fresh sequence for each result set.
how can we achieve this in owb?
any solution for this will be appreciated.
thank you
kumar

My design is like following
SRC1
---->Join1--------------------------->Target1( Table X)<-----Seq1
SRC2
SRC3
----> Join2----------->Target2(Table X)<----Seq1
SRC4
-----> Join3 -------> Target3(Table X)<-----Seq1
SRC5
Here the three 3 targets are for the same Table X as well sequence is same i.e seq1
If the First Join has 10 rows ,Seq1 generates sequence in 1 to 10 while loading target1
But while loading second target,Same Seq1 is generating new sequence from 11 but i am looking to load target2 and target 3 starting from sequence 1 but not from 11 or so.
As per your comments :
you want to load 3 sources to one target with same sequence numbers?
yes
Are you doing match from the other two sources on first source by id provided by sequence (since this is the primary key of the table)?
No
can you please tell me how to approach for this?
Thank You
Kumar

Result Sets with the Microsoft ODBC Driver for Oracle

Howdy all.
I have an Oracle database that I have migrated from MSSQL2K. My front end is mostly VB, and I have many (hundreds) DLL's that use ADO to access the database and execute stored procedures in the database. I cannot seem to get result sets from the Oracle procedures. I have tried passing a SYS_REFCURSOR as an IN OUT parameter, and I have tried returning a SYS_REFCURSOR in a function. The Microsoft ODBC Driver for Oracle does not seem to handle the ref cursors. If I use the Oracle ODBC driver, then ref cursors are handled sort of magically. Just like the result sets are in MSSQL with the SQL Server ODBC Driver.
The question that I would like to pose to anybody willing to answer is this: Is there any way to use the Microsoft ODBC Driver for Oracle without changing the way I do the database access (using ADO connection/command/recordset objects)? I need the same DLL's to work on top of both MSSQL and Oracle.
I know that what I want to do is possible using the Oracle ODBC driver, but this will take some major changes to some of my DB components. I am trying to stay away from this, but it looks like I am going to have to go that route - that is unless somebody wows me with a good answer to this post.

As you are using Microsoft driver which works in XP and does not on Win 2003 you should post this on microsoft forum.

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 return two XML result sets using the function

Hi Experts,
Thanks.

So that I want to return two XML result sets if the query returns more than 50,000 records.
One XML result set with 50,000 and another XML result set with remaining records.
How to incorporate this in my function.
Have the function return a collection of CLOB then.
DBMS_XMLGEN can handle pagination so it's easy to adapt your existing code.
Here's an example fetching data in batches of max. 3 rows each, using a pipelined function :
SQL> create or replace type clob_array is table of clob;
2 /
Type created
SQL>
SQL> create or replace function genXmlRowset (p_deptno in number) return clob_array pipelined
2 is
3    ctx    dbms_xmlgen.ctxHandle;
4    doc    clob;
5 begin
6
7    ctx := dbms_xmlgen.newContext('SELECT empno, ename FROM scott.emp WHERE deptno = :1');
8    dbms_xmlgen.setBindValue(ctx, '1', p_deptno);
9    dbms_xmlgen.setMaxRows(ctx, 3);
10
11    loop
12
13      doc := dbms_xmlgen.getXML(ctx);
14      exit when dbms_xmlgen.getNumRowsProcessed(ctx) = 0;
15      pipe row (doc);
16
17    end loop;
18
19    dbms_xmlgen.closeContext(ctx);
20
21    return;
22
23 end;
24 /
Function created

Reset it by holding the power and home buttons at the same time until you see the Apple logo, then release. You won't lose any data by doing this.

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.

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)

Can I create a result set filter on a SSRS Report similar to what you can do in Excel?

Asking this question in a different way...I have my SSRS Result set. Now the Business User wants to filter down a 15-page report to what they want to specifically see....Sooo my result set has a list of claims. And now the Business User just wants to see
the list of claims by a certain Provider, which is also in the report. So I don't want to put that "filter" on the front-end...within the Stored Procedure that is producing the report because they want to see everything. Is there a way to make SSRS
intelligent enough to parameterize the back-end result set? Or do I need to do it the old fashioned way by allowing for an optional parameter, let them run their report, define the available values by a query similar to the stored procedure filtering, and
let them drill down that way?
I have tried playing around with Dataset filters and a parameter using the existing result set and existing Dataset, but I just cannot seem to get this to work the way I envision. If this entails creating a Function or Procedure within the SSRS, bring it
on...I'm willing to learn. And I do have some VBA experience...so I'm not intimidated.
Again...I apologize for the similar type question, but I felt the need to be a little more clear.
Thanks for your review and am hopeful for a reply.
PSULionRP

I GOT IT!!!
Followed the following...
Here's what I've put into my SSRS Knowledgebase...
Filters/Parameters on the Report Result Set
Request from the Business User to add "parameters" to the Report Result Set. Kind of like auto filtering you can do in Excel
Within the Report Design within Microsoft Visual Studio…
— Insert a new Dataset which is merely carving out the SQL from the working Report Stored Procedure and customizing the SQL for the DISTINCT values that you want
— Insert a NEW Parameter based on the carved out SQL
General → Allow blank value
Allow multiple values
Available Values → Get values from a query
Specify the previously created Dataset
Default Values → Get values from a query
Specify the previously created Dataset
— Insert a Filter back on the original Dataset that is used to create the Report
Expression → Choose the Report Detail Item column name
Operator → In
Value → Physically type in the Parameter Name created previously
Works EXACTLY as I had envisioned. Prompts for the From Date and Thru Date, runs the report, dynamically builds the "optional" parameters/filters,
and then allows the Busimess User to speify or drill down into the result set based on the dynamically built parameter drop-down list.

Can I retrieve a result set from Oracle and then incorporate that result set into my main SQL Server Stored Procedure?

So I have a chunk of data that only resides in Oracle. So I need to capture that information from Oracle. Now before you get over zealous, I did try with an OPENQUERY and it took FOREVER! And I don't know why the OPENQUERY took FOREVER but if I run the same
query directly against Oracle it runs very quickly...like 20 seconds.
So now I'm wondering...can I build a dataset in my SSRS Report that uses an Oracle Data source and an Oracle Stored Procedure in its Dataset that I'll create to aggregate this subset of data and then utilize its result set back in my main reporting
Dataset that will utilize SQL Server? And how can I do that? Can I make my main Dataset reference, say, a #TemporaryTable that is created from my Oracle Dataset in its
I'll continue to Google a few things as I await your review and hopefully a reply.
Thanks in advance for your help.

Hi ITBobbyP,
According to your description you want to use data from a Oracle data source into a DataSet which retrieving data from SQL Server. Right?
In Reporting Services, we can have multiple data sources in one project pointing to different database. And we can use separated dataset to retrieve data from different data source. However, it's not supported to combine the two datasets together
directly. We can only use Lookup(), LookupSet() function to combine fields from different dataset into one tablix when there are common columns between two datasets. This is the only way to make tow result sets together in SSRS.

Lookup Function (Report Builder and SSRS)

Modifying the Default Result Set on the Results Tab of the SQLWorksheet

I have found the previous posts indicating that the default result set size is 50, that it is not currently able to be modified and (good news) that an enhancement will be coming to correct this.
I thought I would give my two cents on how this option might be configured:
Either in the 'View-Options-(output options)' or the 'Tools-Preferences-Environment' areas, have two options. The first would be something like "Max Rows to Display in Results Window" and the second would be sometihng like "Max Rows to Load when end of Current display is reached."
The first option is certainly most essential, but the latter option I have to explain a little. Say you set your max rows to display to 500. You scroll (drag bar, arrow down, etc) to record 501. At this point, the setting on the "Max Rows to Load When End of Current Display is Reached" option comes into play. This setting will then be read to determine how many rows are to be loaded each time the user gets to the current end of display. The second option adds some flexility to how data rows will be displayed after the initial data rows are loaded.
You could just default the number of rows added to the display to the setting set in the "Max Rows to Display in Results Window" setting, although I would say that this would be less flexible. Whatever you do, don't follow the Toad example of loading ALL records when dragging the vertical bar to the bottom of the display grid.
Thank You for your time.

Can Stratus pass an app id to the callback script?

Never mind, I looked at this the wrong way.
My question was: can Stratus pass my callback script some
kind of application id so I can distinguish which AS3 app is making
the request in case I'd have more than one app.
Obviously that's something I can control myself in the
WebServiceUrl setting.

Just print it out as a Javascript variable.

Can I use same result set for two queries?

Hi,
Can I use the same result set for two queries?
For example:
ResultSet rs = null;
rs = ps.executeQuery(query1);
while (rs.next()) {
rs = ps.executeQuery(query2);
while (rs.next()) {
Is it OK to use? or Is there any preformance issues?
Appreciate your help.
Thanks in advance.
Prasad Vagolu

Sure. You have a variable of ResultSet type. First you create a ResultSet and assign it to that variable. Then later you create another ResultSet and assign it to that same variable. Assigning an object reference to a variable takes essentially no time, and at any rate it isn't any faster to assign it to a different variable. Also, no matter whether you use one variable or two, you are still creating two ResultSets.
However, you really should be closing your ResultSets after you finish using them. That's nothing to do with the assigning-to-a-variable question.

How to Colour the fields in the Result Set of the query

Hi all,
I am having a requirement wher the user want to view the queries results with some colour to the char in the result set.
suppose customer is the row he want to view some customers with one color and some with different color.
Is it possible in Bi.
If so Plz let me know
Regards

Hi Priya,
for the macro thing, you will have to create a workbook and store your query into it, because macros are attached to only workbooks and not queries.
in the workbook screen (i.e. excel), go to tools --> Macro --> Visual Basic Editor. or simply press Alt + F11. this will take you to macro editor screen.
you can use code that may look something like below to color the columns, you can also give constant column if they are fixed.
sub ColorColumns(rngTarget As Range, _
    intColor As Integer)
Dim c As Long
    With rngTarget
        .Interior.ColorIndex = intColour
        Next c
    End With
End Sub
You will find some easy and short snippets for this.
