Refcursor IN

Hello All,
I'm using oracle 11gR2
One of our user wants all their LOVs maintained thru a UI. They have close to 50 LOV tables with no. of fields ranging from 5 to 10 with mostly different names.
I'm trying to write a generalized package to get the values, set the values and delete the values. We have permissions/privileges being checked before any of the DML being performed.
for the get procedure, I'm returning a refcursor when they pass in the table name (may not be ideal but....had to) and now starting to work on the set procedure (insert new values). Some of the issues that I'm trying to address is that the number of fields are not constant, the field names are different etc..
Would passing in a refursor work for this scenario? or is there better ways of doing it? Please shed some light.
Thanks in advance
NU

First you need to quit focusing on the solution you seem to want to use (ref cursor) and get back to focusing on defining the problem and the requirements.
Once the complete requirements are available you can start looking for solutions that can be used.

Well you can't do that if the requirements (column names and number of columns) for the 50 LOVs are different.
You either have to make the number and names of columns the same (using a view perhaps) or you will need more than one 'generic' set of code (that is, one for each set of LOVs that is consistent.
What UI are you talking about? A Java middle-tier? You may have a choice of where to put the business rules: in the middle tier so the back-end code is more generic or in the back-end.
I suggest you first need to review the 50 LOVs and determine how many similar sets of them that you have.
Some common attirbutes might be: 1) actual attribute name, 2) display name, 3) actual attribute value, 4) display value/format
The 'display' attributes are what the business user wants displayed and the name they want to use to refer to the attribute ('State Code'). The 'actual' attributes are what is really used in the back-end ('STATE_CD'). For generics you want to use a mapping table so you can map the business name to the actual name and break the dependency.
The key thing is what I said above. Focus on nailing down the requirements. The correct solution will be more readily apparent when you know for sure what all of the issues are.

Problem with refcursor in 11g

Hello,
I have a problem with refcursor in a project migrated from 10 to 11g.
I found this thread from a few years ago that talks about the same problem.
It has no final answer - is it ok to comment the st.close(); in callStoredFunction in the AMImpl.
Re: TP4 - View Object with REF CURSOR - SQLException
Please tell me if the suggested solution on that thread is fine, or ot will cause many unclosed statetements?
Thank you, Nina

Hello All,
I got the solution to the problem.
I was trying to surround the region component using the Structure pane. But instead drag and drop the strechable components on to the region.
Ex: Region got expanded 100% if I surround it with PanelStrechLayout with width and height set to 100%. But I didnit find this Panel StrechLayout when I try to surround it using Structure Pane.

Show refcursor returned by a PL/SQL function ?

Is it possible to show the results returned by a
PL/SQL function that returns a refcursor ?
In sqlplus it goes like this:
SQL> variable a refcursor;
SQL> execute :a := p_front.get_invoice_list;
PL/SQL procedure successfully completed.
SQL> print a;
INVOICE_ID CLIENT_ID INVOICE_D
101 100 01-APR-06
100 100 06-APR-06
If not, this would be on the top of my wishlist...

Looping through a refcursor to get list of dates as a string

hi,
i have a simple procedure which gives me list of from dates and to dates
i need to get the dates a comma separated dates
i am not sure if this can be done directly by doing a for loop on the refcursor or i have to fetch it into a record/array and then concatenate with comma or is there anything else that can be done.
i tried out some stuff like below
ps help me out
the procedure that retruns the list of dates is
CREATE OR REPLACE procedure SALUSER.prm_sp_rpt_payslip_lop_dates(p_empid in int,p_tran_year in int,p_tran_month in integer,o_dates out sys_refcursor)

How to read the data from a refcursor

Hi all,
Here my program . I'm calling pr_test into another program there i need to read the values from refcursor of pr_test program . I dont want use all the values in my second program I need to pass empno and job only.
pls help me out how to read this?
package pg_test
is
type curvartype is ref cursor;
procedure pr_test(p_empno in number, o_curvar_out curvartype);
end;
package pg_test is
procedure pr_test( o_curvar_out curvartype)
is
begin
open o_curvar_out for
select * from emp;
end loop;
end;
end;Thanks,
Venkat.

I dont want use all the values in my second program I need to pass empno and job only.Since your cursor gets all the columns (using the * is not a good way to code the cursor), that is what your other program will get when it calls pr_test procedure. You will have to FETCH all the columns in that other procedure and discard the ones you do not need.
Alternatively, change the code of cursor to select only the columns you would actually need.

Issue with IN parameter of Oracle Procedure returning two RefCursors...

Hi all,
I'm having a nightmare with an Oracle procedure that takes one input parameter and returns two RefCursors as outputs. I recently got help in this forum getting a procedure to work that took no inputs but returned two refcursors and that's still working fine. So, for my current issue I have a procedure defined as follows:
PROCEDURE getQueueInfo(domainKey char, importQueues OUT ODPNet.refcur, exportQueues OUT ODPNet.refcur) IS
BEGIN
    OPEN importQueues FOR SELECT
    source_key, source_applid,
    import_status(source_key) as status,
    time_added, time_processed
    FROM wm_import_source_header
    WHERE source_id = domainKey
    ORDER BY source_key DESC;
    OPEN exportQueues FOR SELECT
    h.source_key, d.source_applid,
    export_status(h.source_key) as status,
    d.source_wire_code, d.destination_wire_code, h.time_added,
    h.time_transmitted
    FROM wm_export_source_header h, wm_export_source_data d
    WHERE h.source_key = d.source_key
      and d.source_id = domainKey
    ORDER BY h.source_key DESC;
END getQueueInfo;This is defined within a package called ODPNet as with my previous procedure and all works fine (I can execute within Oracle SQL Developer and it returns the expected results). Within my .NET application my code is as follows:
            try
                using (OracleConnection conn = new OracleConnection(connString))
                using (OracleCommand comm = new OracleCommand())
                    comm.CommandText = "ODPNet.getQueueInfo";
                    comm.CommandType = CommandType.StoredProcedure;
                    comm.Connection = conn;
                    OracleParameter domainKey = new OracleParameter();
                    OracleParameter importQueues = new OracleParameter();
                    OracleParameter exportQueues = new OracleParameter();
                    domainKey.OracleDbType = OracleDbType.Char;
                    importQueues.OracleDbType = OracleDbType.RefCursor;
                    exportQueues.OracleDbType = OracleDbType.RefCursor;
                    domainKey.Value = "UKBD72";
                    domainKey.Direction = ParameterDirection.Input;
                    importQueues.Direction = ParameterDirection.Output;
                    exportQueues.Direction = ParameterDirection.Output;
                    comm.Parameters.Add(domainKey);
                    comm.Parameters.Add(importQueues);
                    comm.Parameters.Add(exportQueues);
                    conn.Open();
                    comm.ExecuteNonQuery();
                    OracleDataReader dr1 = ((OracleRefCursor)importQueues.Value).GetDataReader();
                    OracleDataReader dr2 = ((OracleRefCursor)exportQueues.Value).GetDataReader();
                    if (dr1.HasRows)
                        while (dr1.Read())
                            result6 += dr1["source_applid"].ToString() + "<br>";
                    else
                        result6 += "No Rows";
                    if (dr2.HasRows)
                        while (dr2.Read())
                            result7 += dr2["source_applid"].ToString() + "<br>";
                    else
                        result7 += "No Rows";
            catch (Exception ex)
                result6 = ex.ToString();
            }The value I want to submit as the IN parameter of the procedure is "UKBD72". but I'm really not sure how to apply this and then return my two refcursors into separate datareaders (except for the input parameter stuff the code above is exactly what I did with the other procedure that returned two ref cursors and still works fine). When I run this code I get no errors, I just get told that each DataReader has no rows returned, which shouldn't be right.
Any help with this would be hugely appreciated.
Cheers,
Seb

Sorry folks, after staring at this over and over, eventually going to sleep and coming back to it with some fresh eyes I realised I was just being a complete idiot - I was feeding the procedure different data in the .NET app than I was when testing in Oracle SQL Developer. Low and behold once I gave it the right data it worked!
Silly me...

Problem with IN OUT Number, OUT RefCursor for EF Model StoredProcedure call

When I call a stored procedure using the EF Model and implicit binding via App.config which has three parameters i.e. 'IN Number', 'IN OUT Number' and 'OUT sys_refcursor', the 'IN OUT Number' is not set correctly on return from the procedure.
The 'IN OUT Number' is for an error code and is set to 12345 on input and is then set to 54321 by stored proceedure for return.
The correct value is returned when the call is via OracleCommand using implicit binding via App.config but remains unchanged when the call is via EF Model and implicit binding via App.config.
The ODP documentaion says you cannot have two OUT RefCursors when using EF Model but does not say you cannot have OUT RefCursor and other non-RefCursor OUT parameters.
The idea behind this type of procedure is to have multiple input parameters to configure and filter the stored procedure and an output result set that consists of an error code and a collection of result rows in a RefCursor.
I am using 11g R2 database and ODP 11g Release 2 (11.2.0.2.30) and ODAC Entity Framework beta.
The query uses Scott/tiger schema with parameters department code, error code and list of employees for department.
code:
PROCEDURE TEST_PARAMETERS
DEPT IN NUMBER,
ERROR_CODE IN OUT NUMBER,
DEPT_EMPLOYEES OUT sys_refcursor
AS
BEGIN
DBMS_OUTPUT.PUT_LINE('DEPT = [' || DEPT || ']');
DBMS_OUTPUT.PUT_LINE('ERROR_CODE = [' || ERROR_CODE || ']');
OPEN DEPT_EMPLOYEES for SELECT empno, ename from emp where deptno = DEPT;
-- set ERROR_CODE for return
ERROR_CODE := 54321;
END TEST_PARAMETERS;
The App.config for implicit RefCursor binding is as follows ...
<oracle.dataaccess.client>
<settings>
<add name="SCOTT.TEST_PARAMETERS.RefCursor.DEPT_EMPLOYEES"
value="implicitRefCursor bindinfo='mode=Output'" />
<add name="SCOTT.TEST_PARAMETERS.RefCursorMetaData.DEPT_EMPLOYEES.Column.0"
value="implicitRefCursor metadata='ColumnName=EMPNO;
          BaseColumnName=EMPNO;BaseSchemaName=SCOTT;BaseTableName=EMP;
          NATIVE_DATA_TYPE=number;ProviderType=Int32;
          PROVIDER_DB_TYPE=Int32;DataType=System.Int32;
          ColumnSize=4;NumericPrecision=10;
               NumericScale=3;AllowDBNull=false;IsKey=true'" />
<add name="SCOTT.TEST_PARAMETERS.RefCursorMetaData.DEPT_EMPLOYEES.Column.1"
value="implicitRefCursor metadata='ColumnName=ENAME;
          BaseColumnName=ENAME;BaseSchemaName=SCOTT;BaseTableName=EMP;
          NATIVE_DATA_TYPE=varchar2;ProviderType=Varchar2;
          PROVIDER_DB_TYPE=String;DataType=System.String;
          ColumnSize=10;AllowDBNull=true'" />
</settings>
</oracle.dataaccess.client>
When the call is via OracleCommand both outputs are correct i.e. ERROR_CODE gets set to 54321 and the correct emplyees for department 10 are returned
code:
private void TestParametersViaOracleCommand()
try
string constr = "DATA SOURCE=ORCL;PASSWORD=tiger;PERSIST SECURITY INFO=True;USER ID=SCOTT";
OracleConnection con = new OracleConnection(constr);
con.Open();
OracleCommand cmd = con.CreateCommand();
OracleDataAdapter adapter = new OracleDataAdapter(cmd);
DataSet ds = new DataSet();
cmd = con.CreateCommand();
cmd.CommandText = "SCOTT.TEST_PARAMETERS";
cmd.CommandType = CommandType.StoredProcedure;
cmd.BindByName = true;
OracleParameter dept = cmd.Parameters.Add("DEPT",
OracleDbType.Int32,
ParameterDirection.Input);
dept.Value = 10;
OracleParameter errorCode = cmd.Parameters.Add("ERROR_CODE",
OracleDbType.Int32,
ParameterDirection.InputOutput);
errorCode.Value = 12345;
// RefCursor output parameter implicitly bound via App.Config
adapter = new OracleDataAdapter(cmd);
adapter.Fill(ds);
// should be 54321 and is ...
Console.WriteLine("after call errorCode.Value = " + errorCode.Value);
Console.WriteLine("list size = {0}", ds.Tables[0].Rows.Count);
// only one table
DataTable deptEmployeesTable = ds.Tables[0];
for (int ii = 0; ii < deptEmployeesTable.Rows.Count; ++ii)
DataRow row = deptEmployeesTable.Rows[ii];
Console.WriteLine("EMPNO: " + row[0] + "; ENAME: " + row[1]);
catch (Exception ex)
// Output the message
Console.WriteLine(ex.Message);
if (ex.InnerException != null)
// If any details are available regarding
// errors in the app.config, print them out
Console.WriteLine(ex.InnerException.Message);
if (ex.InnerException.InnerException != null)
Console.WriteLine(
ex.InnerException.InnerException.Message);
output:
before call errorCode.Value = 12345
after call errorCode.Value = 54321 (should be 54321!)
list size = 3
EMPNO: 7782; ENAME: CLARK
EMPNO: 7839; ENAME: KING
EMPNO: 7934; ENAME: MILLER
However when call is via EF Model the correct employees are returned but the ERROR_CODE parameter is unchanged on return.
code:
private void TestParametersViaEFModel()
var context = new ScottEntities();
Decimal dept = 10;
ObjectParameter errorCodeParameter = new ObjectParameter("ERROR_CODE", typeof(decimal));
errorCodeParameter.Value = 12345;
Console.WriteLine("before call errorCodeParameter.Value = " + errorCodeParameter.Value);
// RefCursor output parameter implicitly bound via App.Config
var queryResult = context.TestParameters(dept, errorCodeParameter);
// should be 54321 and is ...
Console.WriteLine("after call errorCodeParameter.Value = " + errorCodeParameter.Value + " (should be 54321!)");
List<TestParameters_Result> deptEmployeesList = queryResult.ToList();
Console.WriteLine("list size = {0}", deptEmployeesList.Count);
for (int ii = 0; ii < deptEmployeesList.Count; ++ii)
TestParameters_Result result = deptEmployeesList[ii];
Console.WriteLine("EMPNO: " + result.EMPNO + "; ENAME: " + result.ENAME);
output:
after call errorCodeParameter.Value = 12345 (should be 54321!)
list size = 3
EMPNO: 7782; ENAME: CLARK
EMPNO: 7839; ENAME: KING
EMPNO: 7934; ENAME: MILLER
errorCodeParameter.Value IS NOT CORRECTLY RETURNED!
If there is no RefCursor then both outputs are identical i.e. the parameters are being passed in correctly and the problem is not with the 'IN OUT' parameter. Also same thing is true if ERROR_CODE is made an OUT parameter. Also tried changing the position of the parameter in the list but still get same problem i.e. works when OracleCommand but not when EF Model. Also note that the RefCursor results are correct for both types of call i.e. it is just a problem with the value of the 'IN OUT ERROR_CODE' parameter.
I have also enabled debug stepping from Visual Studio 2010 into Oracle PL/SQL as described in
"http://st-curriculum.oracle.com/obe/db/hol08/dotnet/debugging/debugging_otn.htm"
and have verified by inspection that the correct values are being passed into the stored procedure and that the stored procedure is definitely setting the ERROR_CODE to 54321 prior to return.
Most of our stored procedures have these type of parameters i.e. several IN params to configure the work of the stored procedure, an OUT NUMBER parameter for the Error_Code if any and a RefCursor for the result list.
Is this a bug or a feature? Am I doing something wrong?

Just to clarify ....
If the ERROR_CODE parameter is made an 'OUT' parameter instead of an 'IN OUT' parameter the correct return value is given for the OracleCommand invocation but the WRONG value is still returned for the EF Model invocation i.e. just changing the parameter from 'IN OUT' to just 'OUT' does not fix the problem.

Using Refcursor in Callable Statement without using the Oracle Drivers

Hello all,
Is there anyway to have a stored procedure (Oracle 8i) return a refcursor to my CallableStatement without using the Oracle Thin drivers (i'm now using jdbcodbc). I've tried registering my out parameter with every possible type i can think of...REF, JAVA_OBJECT, OTHER, etc. but with no luck.
Help!!!!

Certainly...I connect to the database using the
jdbcodbc driver and when i execute any of the code, i
get the following error:
java.sql.SQLException: [Oracle][ODBC][Ora]ORA-06550:
line 1, column 7:
PLS-00306: wrong number or types of arguments in call
to 'PVISUAL_GET'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
It's bombing on the line that i attempt to register
OracleTypes.CURSOR. It works fine when i use the
oracle thin drivers, but i want to get this puppy
working with the JdbcOdbcDriver. Here's the code:
CallableStatement dbCall =
nt dbCall =
(CallableStatement)connection.prepareCall("{ call
PAK_VISUAL_GET.pvisual_get(?, ?, ?, ?, ?, ?) }");
dbCall.setString(1, sessionKey);
dbCall.setInt(2,
l.setInt(2, Integer.parseInt(storedVizID));
dbCall.registerOutParameter(3,
arameter(3, OracleTypes.CURSOR);
dbCall.registerOutParameter(4,
arameter(4, OracleTypes.NUMBER);
dbCall.registerOutParameter(5,
arameter(5, OracleTypes.VARCHAR);
dbCall.registerOutParameter(6,
arameter(6, OracleTypes.NUMBER);
dbCall.execute();when you don't use oracle thin driver, you cannot use the OracleTypes. but, instead use the java.sql.Types values.Replace dbCall.registerOutParameter(3, OracleTypes.CURSOR); with
dbCall.registerOutParameter(3,java.sql.Types.OTHER). things should be fine.

How to pass a refcursor to a java stored proc

Hi all,
Please forgive me as I am new to Java and JDeveloper....
I want to pass a refcursor to a java stored proc. Does anyone know how to accomplish this?
Thanks,
dayneo

Hi,
As Avi has indicated, you can map ref cursor to java.sql.ResultSet
here are Call Specs and a code snippet from chapter 3 in my book.
procedure rcproc(rc OUT EmpCurTyp)
as language java
name 'refcur.refcurproc(java.sql.ResultSet[])';
function rcfunc return EmpCurTyp
as language java
name 'refcur.refcurfunc() returns java.sql.ResultSet';
* Function returning a REF CURSOR
public static ResultSet refcurfunc () throws SQLException
Connection conn = null;
conn = DriverManager.getConnection("jdbc:oracle:kprb:");
((OracleConnection)conn).setCreateStatementAsRefCursor(true);
Statement stmt = conn.createStatement();
((OracleStatement)stmt).setRowPrefetch(1);
ResultSet rset = stmt.executeQuery("select * from EMP order by empno");
// fetch one row
if (rset.next())
System.out.println("Ename = " + rset.getString(2));
return rset;

How to call refcursor in oracle forms

How to fetch a column in oracle form by using DB prcedure's refcursor.
There was not isseu to create and call the procedure in oracle forms but when I was trying to fetch
a particular column and assing the value to text box, I got an error invalid reference.

DECLARE
   TYPE emp_ref_cur IS REF CURSOR;
   v_emp_curs_qry   emp_ref_cur;
   v_sql            VARCHAR2 (32767);
   v_column1        VARCHAR2 (32767) := 'EMPNO';
   v_column2        VARCHAR2 (32767) := 'ENAME';
   TYPE emp_rec IS RECORD (
      empno   emp.empno%TYPE,
      ename   emp.ename%TYPE
   TYPE emp_rec_ty IS TABLE OF emp_rec;
   v_emps           emp_rec_ty;
BEGIN
   v_sql := 'select ' || v_column1 || ',' || v_column2 || ' from emp ';
   OPEN v_emp_curs_qry FOR v_sql;
   FETCH v_emp_curs_qry
   BULK COLLECT INTO v_emps;
   CLOSE v_emp_curs_qry;
   FOR i IN v_emps.FIRST .. v_emps.LAST
   LOOP
      DBMS_OUTPUT.put_line ('Empno =' || v_emps (i).empno);
      DBMS_OUTPUT.put_line ('Ename =' || v_emps (i).ename);
   END LOOP;
END;
/i hope this is what you want ..

Mapping refcursors with object types in a procedure

Hi all,
I need some help regarding the mapping of refcursors with object types .
Example: Procedure "A" has object types as input/output parameters which lies in the Web Method Application as a API.
We are creating a procedure "B" which has ref cursors as input/ouput parameters
which will map to the Procedure "A"'s object type parameters.
It will be highly needful for the solution.
Regards
Saugata

Your pseudocode has a lot of steps in it, but you didn't say which step you need help with. Since I already covered going from a nested table type to a refcursor, I'll assume you want an example that goes the other way now, like from a refcursor to a nested table type. Here's one ...
SQL>
SQL>
SQL> set serveroutput on
SQL>
SQL> create type nested_table_type as table of varchar2(14) ;
2 /
Type created.
SQL> show errors
No errors.
SQL>
SQL>
SQL> create function func
2    ( p_cursor in sys_refcursor )
3    return nested_table_type
4 as
5    v_nested_table nested_table_type ;
6 begin
7
8    fetch p_cursor bulk collect into v_nested_table ;
9    return( v_nested_table );
10
11 end;
12 /
Function created.
SQL> show errors
No errors.
SQL>
SQL> select func( cursor( select dname from dept ) ) as nested_table from dual ;
NESTED_TABLE
NESTED_TABLE_TYPE('ACCOUNTING', 'RESEARCH', 'SALES', 'OPERATIONS')If your cursor selects objects instead of simple data types, the code is pretty much the same.
SQL> create type object_type as object ( c1 varchar2(14), c2 varchar2(13) );
2 /
Type created.
SQL> show errors
No errors.
SQL>
SQL> create type nested_table_type as table of object_type ;
2 /
Type created.
SQL> show errors
No errors.

8    fetch p_cursor bulk collect into v_nested_table ;

( OBJECT_TYPE('ACCOUNTING', 'NEW YORK'),
    OBJECT_TYPE('RESEARCH', 'DALLAS'),
    OBJECT_TYPE('SALES', 'CHICAGO'),
    OBJECT_TYPE('OPERATIONS', 'BOSTON')
)(NB I manually reformated the query results for clarity).

Error in calling Stored procedure returns REFCURSOR

Hi,
I've written a oracle stored procedure returning REFCURSOR. say,extractorderdespatchconfirmsp('','','','','','H1','ACG','','','','',:rc).
Following statement throwing error.
CallableStatement cs = con.PrepareCall("{extractorderdespatchconfirmsp('','','','','','H1','ACG','','','','',:rc)}");
rs = cs.executeQuery();
Could you rectify this problem and give me the currect code.
riyaz

Your naming convention leaves a little to be desired.
String command = "{CALL extractorderdespatchconfirmsp(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)}";
CallableStatement cstmt = conn.prepareCall(command);
//set the variables here ie, dates need to be a timestamp format. use set timestamp.
cstmt.setInt(1, 2);
cstmt.setString(2, "a string");
cstmt.setInt(3, 0);
//for return values
cstmt.registerOutParameter(3, Types.INTEGER);
cstmt.registerOutParameter(2, Types.INTEGER);
cstmt.execute();
int status = cstmt.getInt(3);
int status2 = cstmt.getInt(2);
cstmt.close();
It took me awhile too to get JDBC to call these right.
