Newbie: compare 2 result sets in procedure
I have two queries. One selects 5 values (all number datatypes), the second query selects 2 values (both number datatypes).
If a value from query 2 exists in the resultset of query 1 - go make table updates using the second value in the select statment of query 2. If there is not a match, update a table with values from query 1.
Currently, I have two cursor for loops, which are nested. This works but of course is horribly slow. What is a better way to process this data?
The number of rows varies between the two resultsets.
Oracle 11.2.0.3.2
Query one sample resultset (normally approximately 25K rows returned):
1701553486214000 104574 6200 9888 55
1701553486102000 104573 6445 9817 54

1701553484067000 104559 6008 10030 41
Query two sample result set (this resultset will always be a sub-set of query one - based on the second column value)
104566 1701524076315000

How do you report from a multiple-result-set stored procedure?
Team,
I am writing a report against a canned stored procedure which returns eight result sets. That is, inside the stored procedure, there are eight SELECT statements which pump to the output. In ADO, you would read the first one, then use SqlDataReader.NextResult to advance the reader to the next one until you have done all eight.
Q1: Have you ever written a Crystal Report against such a sproc? How?
Q2: I see that I could pull this data using ADO.NET if I knew this: Have you ever read such a sproc into a dataset? When I drag-and-drop the sproc into the dataset designer, it only makes a table schema for the first result set. I desire to have a table schema for all eight.
Thanks,

- not a Crystal reports question. Perhaps better posted to some MS / .NET developer forum(?)

Returning result set from procedure out parameter, display with anon block
I'm trying to do something pretty simple (I think it should be simple at least). I want to use a pl/sql procedure to return a result set in an OUT parameter. If I run this code by itself (in the given anonymous block at the end, without trying to display any results), toad says that the PL/SQL procedure successfully completed.
How can I display the results from this procedure? I am assuming that the result set should be stored in the O_RETURN_REDEEM_DTL, but how can I get anything out of it?
I have this package with the following procedure:

Retrive MultiRow Result Set From Procedure
Hi,
Can you please guide me, on ways to retrieve result set with more than one row from procedure. I got two ways...
1. Using Ref Cursor &
2. Using Collection
Do we have any other ways also to do this.

Calling a Stored Procedure with a result set and returned parms
I am calling a stored procedure from a Brio report. The stored procedure returns a result set, but also passes back some parameters. I am getting a message that states that the DBMS cannot find the SP with the same footprint. Besides the result set, the SP returns 3 out parameters: (Integer, char(60), char(40)). Is there something special I need to do in Brio to format the out parameters to be passed back from the SP.
Thanks,
RolandDid you try just declaring the vars?
untested
declare
myCur SYS_REFCURSOR;
myRaw RAW(4);
BEGIN
test (0, 0, myRaw, sysdate, myCur);

JDBC SQL Server Channel Calling Stored Procedure Won't Return Result Set
Good afternoon, Experts
We're calling a stored procedure in a sender communcation channel. I can perform any SQL SELECT statement here, but for some reason when I execute the SP (EXECUTE StoredProcedureName) The Adapter Engine returns the following:
Database-level error reported by JDBC driver while executing statement 'DECLARE @UpdateRecords bit SET @UpdateRecords = 0 EXECUTE ExportToSAP @UpdateRecords'. The JDBC driver returned the following error message: 'com.microsoft.sqlserver.jdbc.SQLServerException: The statement did not return a result set.'. For details, contact your database server vendor.
Even stranger yet is is that this works just fine on our PI-DEV system. I created an identical communication channel connecting to the same database with the same UID and PWD and it won't work in PI-QAS.
Any help/ideas you could share would be greatly appreciated!!!
Thanks,
ChadHi Chad.
Normally, itu2019s a problem with your procedure. The Store Procedure is wrong and something is different between your DEV environment and QAS environment.
Try to ask to DB team check it.

How to use stored procedure which returns result set in OBIEE
Hi,
I hav one stored procedure (one parameter) which returns a result set. Can we use this stored procedure in OBIEE? If so, how we hav to use.
I know we hav the Evaluate function but not sure whether I can use for my SP which returns result set. Is there any other way where I can use my SP?
Pls help me in solving this.
ThanksHi Radha,
If you want to cache the results in the Oracle BI Server, you should check that option. When you run a query the Oracle BI Server will get its results from the cache, based on the persistence time you define. If the cache is expired, the Oracle BI Server will go to the database to get the results.
If you want to use caching, you should enable caching in the nqsconfig.ini file.
Cheers,

Calling stored procedure returning result set
Hi all,
i know this issue is discussed quite often. I did not find an answer in the forums, not in the manual and even not in the examples for stored procedure.
So i try it here once more :)
Description:
GET_SKS:
The GET_SKS procedure is used to generate a number of surrogate keys. It has one input parameter NUM_SKS_IN that specifies the number of keys to generate. The generated keys are returned as a result set.
So i tried:
CallableStatemant sproc_stmt = lsession.connection().prepareCall("{ call Get_SKS(?,?)}");
sproc_stmt.setInt(2,1);
sproc_stmt.registerOutParameter(1,OracleTypes.CURSOR);
sproc_stmt.execute();
ResultSet sproc_result = (ResultSet) sproc_stmt.getObject(1);
I got the exception:
java.sql.SQLException: ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'GET_SKS'
ORA-06550: line 1, column 7:

Stored procedure that returns a cursor (result set)
Hi,
We have a stored procedure that returns a cursor (result set) but when I compliled it and catalouged (introspected) it in the OBPM I got all the primitive type parameters (either IN or OUT) in the proc call except the cursor type (the result set) which is the out param of the stored proc.
Any pointers please?
ThanksResult set is of RowType and is not supported as a Stored Procedure as far as I know.

Performance to fetch result set from stored procedure.
I read some of related threads, but couldn't find any good suggestions about the performance issue to fetch the result set from a stored procedure.
Here is my case:
I have a stored procedure which will return 2,030,000 rows. When I run the select part only in the dbartisan, it takes about 3 minutes, so I know it's not query problem. But when I call the stored procedure in DBArtisan in following way:
declare cr SYS_REFCURSOR;
firstname char(20);
lastname char(20);
street char(40);
city char(20);
STATE varchar2(2);
begin DISPLAY_ADDRESS(cr);
DBMS_OUTPUT.ENABLE(null);
LOOP
FETCH cr INTO firstname,lastname,street, city, state;
EXIT WHEN cr%NOTFOUND;
DBMS_OUTPUT.PUT_LINE( firstname||','|| lastname||','|| street||',' ||city||',' ||STATE);
END LOOP;
CLOSE cr;
end;
It will take about 100 minutes. When I used DBI fetchrow_array in perl code, it took about same amount of time. However, same stored procedure in sybase without using cursor, and same perl code, it only takes 12 minutes to display all results. We assume oracle has better performance. So what could be the problem here?
The perl code:
my $dbh = DBI->connect($databaseserver, $dbuser, $dbpassword,
{ 'AutoCommit' => 0,'RaiseError' => 1, 'PrintError' => 0 })
or die "couldn't connect to database: " . DBI->errstr;
open OUTPUTFILE, ">$temp_output_path";
my $rc;
my $sql="BEGIN DISPLAY_ADDRESS(:rc); END;";
my $sth = $dbh->prepare($sql) or die "Couldn't prepare statement: " . $dbh->errstr;
$sth->bind_param_inout(':rc', \$rc, 0, { ora_type=> ORA_RSET });
$sth->execute() or die "Couldn't execute statement: " . $sth->errstr;
while($address_info=$rc->fetchrow_arrayref()){
my ($firstname, $lastname, $street, $city, $STATE) = @$address_info;
print OUTPUTFILE $firstname."|".$lastname."|".$street."|".$city."|".$STATE;
$dbh->commit();
$dbh->disconnect();
close OUTPUTFILE;

Design a procedure which returns a result set of a select Query
Hi...
Can some one help me out with a brief design or work around for creating a stored procedure which runs a select Query and Returns a result set...
If not a stored procedure, at least a function which makes the job simple....
Awaiting help in this regard ........Hi...
I am sorry for providing insufficient Info...
Actually I am using Oracle 10G DB...
I have a select Query..
Since I am a part of team which is building a Complete Data Driven site, Even an SQL Query and a PL/SQL function body was stored in the Table itself to bring in some kind of Dynamism in the site.... But the master table was loaded with a lot of data and hence Now we decided to Store everythin in a generic package..
I used REF CURSORS to store a result set of a simple SELECT Query.... and declaring it as an out parameter in my Procedure body so that the JAVA team can directly access the Procedure from the JAVA layer....
Now I want to know can I do anything more efficient to carry out the above operation.... -
Stored Procedure With Multiple Result Sets As Report Source : Crosspost
Hello Everyone,
I have an issue where i have created a stored procedure that returns multiple result sets
/* Input param = @SalesOrderID */
SELECT * FROM Orders TB1
INNER JOIN OrderDetails TB2 ON TB1.ID = TB2.ID
WHERE TB1.OrderID = @SalesOrderID
SELECT * FROM Addresses
WHERE Addresses.OrderID = @SalesOrderID AND Addresses.AddressType = 'Shipping'
SELECT * FROM Addresses
WHERE Addresses.OrderID = @SalesOrderID AND Addresses.AddressType = 'Billing'
This is just a quick sample, the actual procedure is a lot more complex but this illustrates the theory.
When I set the report source in Crystal X to the stored procedure it is only allowing me to add rows from the first result set.
Is there any way to get around this issue?
The reason that I would prefer to use a stored procedure to get all the data is simply performance. Without using one big stored procedure I would have to run at least 6 sub reports which is not acceptable because the number of sub reports could grow exponentially depending on the number of items for a particular sales order.
Any ideas or input would be greatly appreciated.
TIA
- Adam
P.S
Sorry for the cross post, I originally posted this question [here|/community [original link is broken];
but was informed that it might be the wrong forum
Edited by: Adam Harris on Jul 30, 2008 9:44 PMAdam, apologies for the redirect, but it is better to have .NET posts in one place. That way anyone can search the forum for answers. (and I do not have the rights to move posts).
Anyhow, as long as the report is created, you should be able to pass the datasets as:
crReportDocument.Database.Tables(0).SetDataSource(dataSet.Tables("NAME_OF_TABLE"))
Of course alternatively, (not sure if this is possible in your environment) you could create a multi-table ADO .NET dataset and pass that to the report.

Returning result sets from PL/SQL procedure to client app.
I was wondering if its possible in Oracle PL/SQL to DECLARE, OPEN a cursor and exit
the procedure without closing the cursor
and then retrieve the resultset from
the client.
Pl let me know..
nullYes, you need to use one OUT parameter in your PL/SQL procedure
to pass the cursor variable to
Java code. You can also return that as a return variable of
PL/SQL function. Get the cursor variable from the resultset using

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.
