Applying sort to a query returned by a stored procedure

I am looking for some advice on the best approach for applying a dynamic sort to a query returned by a stored procedure.
We have a stored procedure that has 3 inputs fields which are used to specify sort columns and it has an additional 3 fields to indicate if the corresponding input column is to be sorted in ascending or descending order. We presently accomplish this by using dynamic SQL in the procedure but this approach has some drawbacks. Ideally we would like these queries to compile just like any other cursor. We have tried using decodes but this does not seem practical or easy to maintain.
This procedure is used by a web application that allows the user to click on a column header to specify their sort preference. The previous sort selection becomes the second sort field and the one before that the third.
Your advice is much appreciated!

I see, so you want to be able to sort by "name desc, age asc, salary asc", for example.
there is no built in option. it's either dynamic sql, or decodes.
the decodes could still work, with only 6 lines, but the problem is handling mixed data types. I'll stick with sort col of 1=name (char), 2=number_col, 3=date_col
order by
decode(sort_order1, 'A', decode (sort_col1, 1,name_col, 2,to_char(number_col,'9999999999.00000'), 3,to_char(date_col,'yyyymmddhh24miss'), 'X'),'X'),
decode(sort_order1, 'D', decode (sort_col1, 1,name_col, 2,to_char(number_col,'9999999999.00000'), 3,to_char(date_col,'yyyymmddhh24miss'), 'X'),'X') DESC,
decode(sort_order2, 'A', decode (sort_col2, 1,name_col, 2,to_char(number_col,'9999999999.00000'), 3,to_char(date_col,'yyyymmddhh24miss'), 'X'),'X'),
decode(sort_order2, 'D', decode (sort_col2, 1,name_col, 2,to_char(number_col,'9999999999.00000'), 3,to_char(date_col,'yyyymmddhh24miss'), 'X'),'X') DESC,
decode(sort_order3, 'A', decode (sort_col3, 1,name_col, 2,to_char(number_col,'9999999999.00000'), 3,to_char(date_col,'yyyymmddhh24miss'), 'X'),'X'),
decode(sort_order3, 'D', decode (sort_col3, 1,name_col, 2,to_char(number_col,'9999999999.00000'), 3,to_char(date_col,'yyyymmddhh24miss'), 'X'),'X') DESC,Message was edited by:

Updatable ADO recordset returned by a stored procedure

I am trying to have an updatable ADO recordset returned by a stored procedure.
However, LockType for this recordset is always adLockReadOnly.
What needs to be done to have LockType changed?
I am using the following simplified example from Oracle doc. According to Oracle® Provider for OLE DB Developer's Guide 10g Release 2,
the following ADO code sample sets the Updatability property on a command object to allow insert, delete, and update operations on the rowset object.
Dim Cmd As New ADODB.Command
Dim Rst As New ADODB.Recordset
Dim Con As New ADODB.Connection
Cmd.ActiveConnection = Con
Cmd.CommandText = "SELECT * FROM emp"
Cmd.CommandType = adCmdText
cmd.Properties("IRowsetChange") = TRUE
Cmd.Properties("Updatability") = 7
' creates an updatable rowset
Set Rst = cmd.ExecuteHowever, the result is not updatable. Can you please advise.

Returning a REF CURSOR is certainly the easiest of the options, particularly if you're trying to use ADO. Without doing something really klunky, all your options are going to result in read-only result sets.
Assuming you have a procedure-based interface to your data, the easiest option is generally to do your own updates by explicitly calling the appropriate stored procedures.
As a bit of an aside, in order to offer updatable result sets, the ODBC/ OLE DB/ etc provider generally has to do something along the lines of
1) Take the SQL statement you pass in
2) Modify it to select the ROWID in addition to the other columns you're selecting
3) Store the ROWID internally and use that as a key to figure out which row to update
Once you eliminate the ability of the client to manipulate the query, you've pretty well eliminated the ability of the driver to implement generic APIs for updates. The client at that point has no idea which row(s) in which table(s) a particular value is coming from, so it has no idea how to do an update. You generally have to provide that knowledge by coding explicit updates.

How to apply sort on an already dispaled resultset from a procedure

Hi,
I have a data block for which the 'query data source type' is PROCEDURE. When I query the block all the records in the procedure are displayed. Then I query for a specific value for the DATE column (ex: 27/07/2010) and it displays records for only 27/07/2010. Now I want to sort the displayed records.
My columns are DATE, TRANSACTION NUMBER, PROJECT CODE
I have a button each for DATE, TRANSACTION NUMBER, PROJECT CODE to do the sorting. When I click on the PROJECT CODE sort button , the already retireved records for 27/07/2010 must be sorted according to project code.
But this is not happening. The current coding will query the data block for all the records and then apply the sorting for DATE column.
Please advise.

Actually i don't know but what i gave u but i have read that If you attempt setting the where clause in the block it is totally ignored.
i hardly search just found the following...
Subject: How to Filter Rows on Block Based on Stored Procedure in Oracle Forms?
Doc ID: Note:1078147.6 Type: PROBLEM
Last Revision Date: 22-JUN-2004 Status: PUBLISHED
Problem Description:
====================
Whilst in ENTER QUERY mode you would like to specify a search criteria to
restrict the results of your query. The block on which this query resides
is based on a stored procedure.
Problem Explanation:
====================
If you attempt setting the where clause in the block it is totally ignored.
This happens with both the 'Ref Cursor' or 'Table of Records' variable.
Problem References:
===================
[Search Words: filter ]
Solution Summary:
=================
With Forms 5.0 and above, you can use the Tools--> Datablock Wizard menu
in the Object Navigator to enter the datablock wizard in a re-enterant mode.
You can then specify the query criteria there.
Alternatively, you can pass the query criteria from Forms to the stored
procedure as an IN argument. You can then use the parameter with the
select statement (in the procedure you have created using the 'Table of Records
or 'Ref Cursor').
Solution Description:
=====================
If the blocks were created using the Datablock Wizard with the
"stored procedure" radio button, you can always re-enter the datablock wizard
for that block by clicking on the Tools-->Datablock Wizard. If you go to the
Query tab on the bottom of the tab page you will notice that it requests the
name of the parameter. This is where you enter -
   :parameter.<parameter_name>
This method relies on having a parameter in the form that passes the
value, for example p_deptno, into the stored procedure. This is done in order
to get the corresponding records from the emp table for all employees who work
in that deptartment.
Additionally create a PRE-QUERY trigger and assign the value of the deptno you
are passing through this parameter using the following:
   (:parameter.<parameter_name>:= :dept.deptno).
If the blocks were created manually, however, YOU CANNOT use the re-enterant
option to go to the Datablock Wizard. For these type of blocks, use the method
suggested below.
METHOD FOR MANUALLY CREATED BLOCKS:
===================================
Re-enter the Datablock Wizard by using the Tools--> Datablock Wizard menu of the
Object Navigator. You will notice that you will not be able to see any
procedure in the Datablock Wizard in re-enterant mode.
To use this method, you will need to include one more parameter to your query
procedure as an IN parameter. For example, if you are passing deptno as query
criteria, click on the "Query Data Source Arguments" of your block property
sheet and include the following:
    ARGUMENT NAME: set to P_DEPTNO or (any variable name)
    TYPE: set to the appropriate datatype, for example, NUMBER
    TYPENAME: set to dept.deptno%type, for example
    MODE: set to IN
    VALUE: set to :dept.deptno(the :blockname.itemname you are passing
                               as query criteria.).
In the query procedure, include this parameter as an IN argument, and as the
2nd parameter. For example:
    Procedure empquery_refcur(emp_data IN OUT empcur, v_dno IN number) AS ....
Finally, include this paramter in your select statement of either 'Table of
Records' or 'Ref Cursor' as
    select empno, ename
     from emp
      where deptno=nvl(v_dno, deptno);But no chance to Sort it may be from inside the procedure itself.
Hope this helps...

Abdetu...

Return records from Stored Procedure to Callable Statement

Hi All,
I am createing a web application to display a students score card.
I have written a stored procedure in oracle that accepts the student roll number as input and returns a set of records as output containing the students scoring back to the JSP page where it has to be put into a table format.
how do i register the output type of "records" from the stored function in oracle in the "registerOutParameter" method of the "callable" statement in the JSP page.
if not by this way is there any method using which a "stored function/procedure" returning "record(s)" to the jsp page called using "callable" statement be retrieved to be used in the page. let me know any method other that writing a query for the database in the JSP page itself.

I have a question for you:
If the stored procedure is doing nothing more than generating a set of results why are you even using one?
You could create a view or write a simple query like you mentioned.
If you're intent on going the stored procedure route, then I have a suggestion. Part of the JDBC 2.0 spec allows you to basically return an object from a CallableStatement. Its a little involved but can be done. An article that I ran across a while back really helped me to figure out how to do this. There URL to it is as follows:
http://www.fawcette.com/archives/premier/mgznarch/javapro/2000/03mar00/bs0003/bs0003.asp
Pay close attention to the last section of the article: Persistence of Structured Types.
Here's some important snippets of code:
String UDT_NAME = "SCHEMA_NAME.PRODUCT_TYPE_OBJ";
cstmt.setLong(1, value1);
cstmt.setLong(2, value2);
cstmt.setLong(3, value3);
// By updating the type map in the connection object
// the Driver will be able to convert the array being returned
// into an array of LikeProductsInfo[] objects.
java.util.Map map = cstmt.getConnection().getTypeMap();
map.put(UDT_NAME, ProductTypeObject.class);
super.cstmt.registerOutParameter(4, java.sql.Types.STRUCT, UDT_NAME);
* This is the class that is being mapped to the oracle object.
* There are two methods in the SQLData interface.
public class ProductTypeObject implements java.sql.SQLData, java.io.Serializable
    * Implementation of method declared in the SQLData interface. This method
    * is called by the JDBC driver when mapping the UDT, SCHEMA_NAME.Product_Type_Obj,
    * to this class.
    * The object being returned contains a slew of objects defined as tables,
    * these are retrieved as java.sql.Array objects.
     public void readSQL(SQLInput stream, String typeName) throws SQLException
        String[] value1 = (String[])stream.readArray().getArray();
        String[] value2 = (String[])stream.readArray().getArray();
     public void writeSQL(SQLOutput stream) throws SQLException
}You'll also need to create Oracles Object. The specification for mine follows:
TYPE Detail_Type IS TABLE OF VARCHAR2(1024);
TYPE Product_Type_Obj AS OBJECT (
value1 Detail_Type,
value2 Detail_Type,
value3 Detail_Type,
value4 Detail_Type,
value5 Detail_Type,
value6 Detail_Type,
value7 Detail_Type,
value8 Detail_Type);Hope this helps,
Zac

You need to have either OUTPUT parameters or use RETURN statement to return a value in stored procedures. RETURN can only return integer values whereas OUTPUT parameters can be of any type
First modify your procedure to define return value or OUTPUT parameter based on requirement
for details see
http://www.sqlteam.com/article/stored-procedures-returning-data
Once that is done in SSIS call sp from Execute SQL Task and in parameter mapping tabe shown above add required parameters and map them to variables created in SSIS and select Direction as Output or Return Value based on what option you used in your
procedure.

XMLType in a an object returned by a stored procedure

Hi,
In my project, i'm using stored procedures defined by the schema's owner. Some of these procedures/functions return complex data (defined as objects in the database). This objects contains XMLTYPE data.
When i call one of these stored procedures through JDBC, i've got an error ORA-01427. I watched when this exception is thrown and i found that appens when i do something like this :
OPAQUE op = (OPAQUE)arr[1]; //the XMLTYPE in the STRUCT object returned by JDBC
XMLType xt = oracle.xdb.XMLType.createXML ( op );
I wanted to know what was the type of the object behind i get something like "class [B2".
Anyone encoutered this problem?

I forgot some precisions. This appens when i use a user who is not the owner of the schema. When i use the owner, everything is fine.

OCI8: returning cursors from stored procedures

The short version of my question is:
In OCI8, how do open a cursor from the database stored procedure, return it to my C++ program and fetch from it, given that in OCI8 cursors and cursor functions are becoming obsoleted?
The long version of the same question is:
I am converting my C++ code from the Oracle 7.3 OCI driver to the Oracle8 OCI driver. One thing I did very frequently in Oracle 7.3 OCI code is open a multi-row select cursor within a stored procedure and return that cursor to my program. In the program, I would then do the fetching with the returned cursor. This was very useful, as it allows me to change the queries in the stored procedure (for example, to append information to certain columns or make some data in all uppercase) without recompiling the application due to a changed SQL string.
My 7.3 psuedocode is as follows:
stored procedure def:
TYPE refCurTyp IS REF CURSOR;
FUNCTION LoadEmployeeData RETURN refCurTyp;
stored procedure body:
FUNCTION LoadEmployeeData RETURN refCurTyp IS
aCur refCurTyp;
BEGIN
OPEN aCur FOR
SELECT emp_id, emp_name
FROM employee_table
ORDER BY emp_name;
return aCur;
END;
OCI code: // all functions are simplified, not actual parameter listing
// declare main cursor variable #1 and return cursor variable #2
Cda_Def m_CDAstmt, m_CDAfunction;
// open both cursors
oopen(m_CDAstmt, ...);
oopen(m_CDAfunction, ...);
// bind cursor variable to cursor #2
oparse(&m_CDAstmt, "BEGIN :CUR := MYPACKAGE.LoadEmployeeData; END;");
obindps(&m_CDAstmt, SQLT_CUR, ":CUR", &m_CDAfunction);
// run cursor #1
oexn(&m_CDAstmt);
// bind variables from cursor #2, and fetch
odefineps(&m_CDAfunction, 1, SQLT_INT, &m_iEmpId);
odefineps(&m_CDAfunction, 2, SQLT_CHAR, &m_pEmpName);
while (!ofen(&m_CDAfunction))
// loop: do something with fetch
// values placed in m_iEmpID and m_pEmpName
This works perfectly, and has really helped to make my code more maintainable. Problem is, in Oracle 8 OCI both cursors and the cursor functions (such as oopen()) are becoming obsoleted. Now it uses statement and environment handles. I know I can still use Cda_Def and cursors--for a while--within OCI8, but I need to know the official up-to-date method of returning a cursor from the database and fetching within my C++ code. Any code fragment, or explanation of what I need to do in OCI8 would be appreciated (perhaps I need to bind to a statement handle instead? But the stored procedure still returns a cursor.)
The Oracle8 OCI has a new SQLT_ type, SQLT_RSET, which the header file defines as "result set type". Unfortunately, it's almost completely undocumented in the official documentation. Am I supposed to use this instead of the obsolete SQLT_CUR?
Thanks,
Glen Mazza

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.

Returning recordset from stored procedures

Hi
I am trying to get a stored procedure to return multiple values (i.e. a recordset) and want to access them from JDBC. Is that possible?

You can return nested tables and varrays using JDBC. See chapter 10 of the Oracle JDBC Developer's Guide.

Returning object from stored procedures

I am having a lot of trouble finding an example to demonstate how I return a Java/DB Object from a Java Stored Procedure. All the examples I have been able to find return one of the native types (VARCHAR, NUMBER, etc). As an example...
public static DataPoint getPoint() {
  return new DataPoint(
      new Timestamp(System.currentTimeMillis()),
      new BigDecimal(50.0));
Assuming DataPoint is a Java class mapped to an Oracle Data Type created via the following statement.
create or replace type data_point as object (
  p_date date,
  p_data number
After loading and publishing the procedure I get no (zero, 0) rows returned when calling. I should be getting one row returned.
Thanks,
Mike

Mike,
You said:
Assuming DataPoint is a Java class mapped to an Oracle
Data TypeI think your assumption is incorrect.
In any case, isn't this what "TopLink" is used for?
(I don't know, since I don't use "TopLink".)
Have you tried the TopLink/JPA forum?
Good Luck,
Avi.

14/11    PLS-00428: an INTO clause is expected in this SELECT statement

Within PL/SQL code, the results of a query have to be returned from the SQL engine to the PL/SQL engine, hence why it is asking you to include an INTO within your query. Note that the PL/SQL engine is running on the database server so it has no interface to display output to. To output from within PL/SQL you would have to write the data out yourself to whatever output you want e.g. use DBMS_OUTPUT to put the data to the standard output buffer (which can then be read by SQL*Plus if serveroutput is set to "on") or written out to a file on the server, or written out to a table.
You are assuming that because you can execute SQL from SQL*Plus and spool the output, you can do the same within PL/SQL. This is not the case. When SQL*Plus issues a SQL statement, it goes to the SQL engine and the results of that cursor (as an SQL query is a cursor) are collected by SQL*Plus and it displays them itself. When PL/SQL issues a SQL statement, it goes to the SQL engine and the results of that cursor come back to PL/SQL. PL/SQL doesn't have a display mechanism, so the results have to be collected INTO something.
Hope that's clear.

How to capture return value from stored procedure?

Hi All,
I want to capture the retun values from this procedure to a table - CALL SYS.GET_OBJECT_DEFINITION('SCHEMA_NAME', 'TABLE_NAME').
The below approach is not working -
Insert into STG.STG_DDL
Call SYS.GET_OBJECT_DEFINITION('DWG', 'DWG_SITE')
Could you please have a look on the same?
Thank you,
Vijeesh

Thanks a lot Everyone.
Considering the discussed options, and an approach explained in this thread - -http://scn.sap.com/thread/3291461 , I have written an SQL to build the Alter statements to add the columns & Constrains to table.

SQL Adapter Crashes with large XML set returned by SQL stored procedure

Hello everyone. I'm running BizTalk Server 2009 32 bit on Windows Server 2008 R2 with 8 GB of memory.
I have a Receive Port with the Transport Type being SQL and the Receive Pipeline being XML Receive.
I have a Send Port which processes the XML from this Receive Port and creates an HIPAA 834 file.
Once a large file is created (approximately 1.6 GB in XML format, 32 MB in EDI form), a second file 1.7 GB fails to create.
I get the following error in the Event Viewer:
Event Type: Warning
Event Source: BizTalk Server 2009
Event Category: (1)
Event ID: 5740
Date:  10/28/2014
Time:  7:15:31 PM
User:  N/A
The adapter "SQL" raised an error message. Details "HRESULT="0x80004005" Description="Unspecified error"
Is there a way to change some BizTalk server settings to help in the processing of this large XML set without the SQL adapter crashing?
Paul

Could you check Sql Profiler to trace or determine if you are facing deadlock?
Is your Adapter running under 64 bits?
Have you studied the possibility of using SqlBulkInser Adapter?

How to query DDL locks on stored procedures/functions and packages?

Hi!
The subject says it all: How do I see existing DDL locks on stored procedures/functions and packages?
While a procedure is executed it can't be deleted or replaced, so there has to be a DDL lock on it. The information does not seem to be in V$LOCK or V$LOCKED_OBJECTS.
Thanks!

Hello,
Here you can find an article about the view DBA_DDL_LOCKS:
[http://www.praetoriate.com/int_40.htm]
If you don't have this view on the Data Dictionary, you may have
to execute the "OH/rdbms/admin/catblock.sql" script first.
Hope it can help.
Best regards,
Jean-Valentin
