Manage several results from stored procedures
Hi,
I'm calling a stored procedure which in turn calls six other stored procedures and I'm getting six results in return. But the following code only ends up in one result in the resultset (the first one):
// Define stored procedure
String sp = "EXEC GET_XXX";
CallableStatement cs = null;
ResultSet rs = null;
// Connect to database
Connection con = getConnection();
// Prepare statement
cs = con.prepareCall(sp);
// Excecute Sql query
rs = cs.executeQuery();How can I manage several results?
Not much help, but I couldn't tell you how to do this using PDO. If however, you want to know how to do it without PDO (i.e. via OCI8 PHP functions directly), let me know and I will post some code...

Populate report page based on results from stored procedure
Is it possible to populate a report page in APEX based on the results from a stored procedure? If so, how do I do it? Do I write a stored procedure with a ref cursor as out parameter?
I would use a stored procedure to return the values for a form but not for a report. For a
report, I would use a pipelined function. See an example here:

"table type" result from stored procedure (Oracle 10g) for physical service
Hello,
I'm trying to create a physical service based on a stored procedure which returns a table type like this:
SQL
-- create table
create table myTable ( "col1" VARCHAR2(250) not null enable, "filtercol1" VARCHAR2(250), "filtercol2" VARCHAR2(250), "sortcol1" VARCHAR2(250), "sortcol2" VARCHAR2(250), "sortcol3" VARCHAR2(250))
-- create return type
create or replace type myResultType as table of varchar2(250);
-- create function
create or replace function getResult(param1 in varchar2, param2 in varchar2, orderby in varchar2) return myResultType as
query_str VARCHAR2(1000);
myResult myResultType;
begin
query_str := 'select m.col1 from myTable m where m.filtercol1 like :param1 and m.filtercol2 like :param2 order by ' || orderby;
execute immediate query_str bulk collect into myResult using param1, param2;
return myResult;
end getResult;
The wizard for creating the physical service complains that it can't find the return type and I have to create a schema by myself. How should it look like? I can't find a sample in the documentation.
Thanks for any help,
GuidoOk, now the wizard produces something like this:
(::pragma function <f:function xmlns:f="urn:annotations.ld.bea.com" visibility="protected" kind="library" isPrimary="false" nativeName="GETRESULT" nativeLevel2Container="MY_SCHEMA" style="storedProcedure">
<nonCacheable/>
<params xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdt="http://www.w3.org/2004/07/xpath-datatypes" xmlns:pn1="ld:physical/SQLServices/MY_TMP_TABLE" >

<param name="RETURN_VALUE" kind="out" xqueryType="pn1:MY_TMP_TABLE" nativeTypeCode="0" nativeType="RowSet"/>
<param name="PARAM1" kind="in" xqueryType="xs:string" nativeTypeCode="12" nativeType="VARCHAR2"/>
<param name="PARAM2" kind="in" xqueryType="xs:string" nativeTypeCode="12" nativeType="VARCHAR2"/>
<param name="ORDERBY" kind="in" xqueryType="xs:string" nativeTypeCode="12" nativeType="VARCHAR2"/>
</params>
</f:function>::)
declare procedure f1:GETRESULT($PARAM1 as xs:string, $PARAM2 as xs:string, $ORDERBY as xs:string) as schema-element(t1:GETRESULT) external;
Then WorkSpace Studio complains about: "... error: cos-element-consistent: Type of 'RETURN_VALUE' is inconsistent with another element with the same name in this content model. "
If I rename one RETURN_VALUE to RETURN_VALUE1 (the param name and in the schema file) the error is gone, but if I try to test the method I get:

How to generate a report from stored procedure
I would like to generate a report from stored procedure.
I used to work on sql server. this can be done as easy as put a select statement at the end of stored procedure.
The resule can be displayed on the development IDE, like sql developer or consume by Java JDBC client.
is there equivalent way to do this in Oracle stored procedure?Hi,
What type of report you are looking..for.. ??
As you said that "I used to work on sql server. this can be done as easy as put a select statement at the end of stored procedure. "
When you execute it will return the result set and you will display directly on the FrontEnd.. Is my Understanding is correct Up to here.
See, In oracle you have call some custom stored procedures as you did in SQL Sever, but you have return the Results Sets, with help of Out put paramter, Either Cursors or Varrays..
or Else you can generate the Html reports based on your requirement, HTML can be used in the stored procedures of Oracle which will generate for your, you need to code it.
I could not able get the relevant link for your reference.
I will get back to you on this.

Best method to transfer large strings (XML data) to/from stored procedure
Hi!
I'm trying to call a PL/SQL procedure from Java. The procedure inputs a string (XML) that is parsed, and returns a result string (also XML).
Typical size of the string is 5kb -> 1mb.
I can see two possible solutions:
1) String / LONG
2) CLOB (Using DMBS_LOB.createTemporary and getting a CLOB locator and passing the locator to the stored procedure)
Does anyone have other suggestions?
What is the fastest method for transferring XML structures from to and from stored procedures?
AndersAnders,
I would say it depends on your requirement. Both the methods have some advantages and disadvantages.
Using a CLOB means that you have to use vendor specific libraries but this is more extendible and I fast too.
Using String/Long will be more portable in the long run but again you lose on speed/performance.
Just a doubt of mine... If I got it correct, you are transforming one XML to another XML based on some conditions. Why dont you use XSL and XSL StyleSheet Processor packaged with XDK for this? I think this would be the fastest way.
Hope this helps. -
URGENT : Return Bulk data from Stored Procedure
Hi,
Tell me, how do I return a bulk of data which
does not exist in the data base
but is concluded while the Stored Procedure is executed
from the Stored procedure
to the C++ program.
For Example:
Table ABC
Field1 Field2 Field3
A 1 3
B 1 5
C 2 10
Table DEF
Field1 Field2 Field3
D 10 24
E 3 16
F 8 19
SP_TESTING
Depending on the values in both the tables
for some range of conditions,
a conclusion X is derived for each range value of the
condition range.
Now I need to return this bulk of data X with the
condition they belong to
back to the C++ code calling it....
NOTE : A stored procedure is requited as there is a lot
of processing
required before we conclude the result X for each value
in the condition range.
If I execute this code from C++ instead of Stored
procedure
it is very slow and speed is a prime requirement of my
system.
Also i'm not using any MFC class to access database.
I'm using ConnectionPtr, RecordsetPtr and _CommandPtr
from msado15.dll for database access...
One solution to this could be use of Temp tables.
As this process is used by a lot of different stored
procedures having a common
temp table to all will need something like 50 NUMERIC
fields, 50 VARCHAR fields
and so on, which doesn't seem like a very good solution
to this problem.
Sounds like something I would have done while in school,
implement a dumb solution.
So, please suggest me a solution as to how do I return
bulk data in the form
of recordsets from stored procedure.
Regards

Ora-06550 returning data from Stored Procedure and Entity Data Model
Hi.
I'm creating an application that uses a WCF Service to return data. I also created a proyect with the EDMX design and mapped most of my DBModel to a classes context. I have added some of the procedures as well. One of them receive some parameters and return a Sys_RefCursor, that is populated according to the parameters.
I have declared the "<add >" tags in the Web.Config and imported the function of the Procedure. When I call the Asyncronous function I get different exceptions:
1. If I call the function, with all of the parameters i get:
Oracle.DataAccess.Client.OracleException: ORA-06550: línea 1, columna 8:
PLS-00306: número o tipos de argumentos erróneos al llamar a
'SP_HECHOSJURITER'
ORA-06550: línea 1, columna 8:
(wrong number or types of arguments in call to 'SP_HECHOSJURITER')
2. If i just set 1 parameter in the SP, returning the same type of data, I get:
Error al recibir la respuesta HTTP a
http://localhost/Procalculo.CGFM.SIGOC.DatosServices/ServiceDatos.svc.
(failed to receive http response. error 12152)
3. If I don't set any parameters in the procedure, it works fine, and return correct data.
It exclusively happen with one entity.
Any clue?
I appreciate any help.When you return result sets from stored procedures to Entity Framework, you are very likely using implicit result sets. Implicit result sets don't need to be declared as a parameter in code, only in the <add> tags to define the metadata in the .NET config file.
For example, in the EF Oracle By Example, you'll see that the stored procedure in the function import has three parameters, but only two are declared in the code. The third one was defined in the config file.

Problem with execute SSIS package from stored procedure

Returning rowcount and resultset from stored procedure
Hello,
In SQL Server you can return multiple resultsets from stored procedure by simple SELECT statement. But in Oracle, you have to use SYS_REFCURSOR.
Sample code:
CREATE OR REPLACE PROCEDURE sp_resultset_test IS
t_recordset OUT SYS_REFCURSOR
BEGIN
OPEN t_recordset FOR
SELECT * FROM EMPLOYEE;
END sp_resultset_test;
Is there any other way in Oracle 10 or 11 ?
Thank You.What is the requirement? Oracle is far more flexible than SQL-Server... with numerous features that do not exist in SQL-Server. (Fact)
One of the biggest mistakes you can make is to treat Oracle like SQL-Server... trying to match feature A1 in SQL-Server to feature B3 in Oracle.
Does not work that way.. rather then stick to SQL-Server as SQL-Server does SQL-Server specific features far better than Oracle.
So instead of trying to map what a T-SQL stored proc to do to an Oracle ref cursor (even to the extent of using that very silly sp_ prefix to name the proc), tell us the problem and requirements... That way we can tell you what Oracle features and options are best used to solve that problem - instead of competing in some unknown feature comparison event with SQL-Server. -

assume both query returns equal number of rows.. however both are not related to each other..It sounds like what you need is a ref cursor.
First thing to remember though is that cursors do not hold any data (see: {thread:id=886365})
In it's simplest form you would be creating a procedure along these lines...
