Got my REF CURSOR, how to output?

I started with this code:
Re: find first record in the tree
and get the dbms_output I'm looking for. What I don't understand is how to get the output into the refcursor OUT. I've read about FETCH INTO variables, but how does that get to the REF?
There is an Oracle Form calling this procedure, if that makes any difference.

Here an example of an stored procedure with REF CURSOR output
CREATE OR REPLACE PROCEDURE Test_Proc
(pIPI_EmpId IN PLS_INTEGER,
pORC_RefCur OUT SYS_REFCURSOR)
IS
BEGIN
OPEN pORC_RefCur FOR
SELECT Employee_Name
FROM Employee
WHERE Employee_Id = pIPI_EmpId;
END Test_Proc;
Calling the procedure from Oracle Form
DECLARE
vRC_RefCur SYS_REFCURSOR;
vT_Employee Employee.Employee_Name%TYPE;
BEGIN
Test_Proc(Form.Block.Employee_Id, vRC_RefCur);
LOOP
FETCH vRC_RefCur INTO vT_Employee;
EXIT WHEN vRC_RefCur%NOTFOUND;
Form.Block.Employee_Name := vT_Employee;
END LOOP;
END;

STORED PROCEDURE/REF CURSOR: How to output entire buffer

I wrote a Stored Procedure wherein I use a Cursor to extract multiple
rows and columns. I then write them into the buffer
(dmbs_output.put_line). But when I try to capture the entire result
into an OUT variable, I only get the last buffered line.
So how do I output the entire buffer- all rows and columns? In other words (maybe), how do I use dbms_output.get_lines() to assign value to an OUT variable?
Alternatively, using REF CURSOR as OUT variable, I added the following to "CREATE OR REPLACE PROCEDURE ... ()":
cursor_out_test OUT cursor_test
But when I tried:
DEFINE CURSOR TYPE cursor_test IS REF CURSOR RETURN table%ROWTYPE;
...or...
DECLARE TYPE cursor_test IS REF CURSOR RETURN table%ROWTYPE;
I still got syntax errors.
In one line, what I am trying to do is break the result array at the database level rather than at the application level.
Cheers, Bill
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14261/sqloperations.htm#LNPLS00605

I did the following:
OPEN CURSOR x
     LOOP
          FETCH CURSOR x INTO col1, col2
          (EXIT WHEN...)
          variable_line := col1 || col2
     END LOOP
CLOSE CURSOR
But after closing this cursor, variable_line contains only the last buffered line. I want all the looped lines (without using associative arrays, nested tables etc). So I guess I am just looking for some way to append data lines- adding chr(10) doesn't work either.
Cheers, Bill

Using Ref cursor from Procedure output in BPEL

Hi
Can any body help me ..
The output variable of db adapter is refcursor from stored procedure. in ref cursor i will get xml from a clob variable. how to use it in bpel...can an body help me how to do it....

APEX is based on Oracle Database. Whatever you can do with PL/SQL, the same can be done with APEX also. APEX stores the application definition in the form of metadata.
So if you put all your logic and code in packages, procedures or functions then it will be really good compact and modular approach.
Bottom line is that you can do all of those.
Check the documentation at

Ref Cursor - How to append records into ref cursor?

Hi,
Is it possible to append ref cursor?
Iam having a procedure which accepts 1 string as input
parameter. That string will have list of ID delimited by comma.
I want to extract & match every ID with some tables.
My problem is for first ID i would get 10 records
and for 2nd ID i 'l get other 20 records. But while returning
i need to send the same(10 + 20 records) as ref cursor(OUT parameter).
But in below given code i could send only last 20 records. first
10 records are not append/updated into ref cursor.
How to append 2nd 20 records with 1st 10 records? so that i can
send all the 30 records.
Here goes my code...
CREATE OR REPLACE PROCEDURE getCRMGroupsAndRollups_PRC

Ref Cursor - how to access through parameter name

Hi,
I'm using the below table and sample data. The below script named 'Script1' works well, my concern is values for the first and second parameters need to be used for the thrid and fourth one as well.
When I try with 'Script2' it gives "ORA-01008: not all variables bound ORA-06512: at line 17" error. I know Paramterized cursor can handle this effecively, since it is a dynamic SQL, I need to use from a parameter table, I don't have any control over the number of parameteters, parameter name, type and other things. So, I cannot go for parameterized cursor.
As of now, for my requirement, Script1 works fine, is there any way to make Script2 to work as well, I need to pass paramters by name, not by position, please give your suggestions, thank you.

How to open a Ref cursor in Oracle Reports

I have a stored procedure that returns a ref cursor as an output parameter. I want to call this stored procedure in Oracle Reports After Form trigger. I am having trouble with the syntax of the output parameter. Event_record is the name of the cursor.
After Form Trigger
pkg_DEAL_WHITESHEET_CONCERTS.prc_Event_Information(:p_field_6,event_record);
Error: Event_record must be declared

Re-Write the procedure as Package Spec and Body. Declare the REFCursor in the Package Spec. Probably that helps.

How to populate table name dynamically to a ref cursor

Hi,
I came accross with a requirement that in ref cursor how can i pass the table name

that should be dynamically changed
Like below
open ref_cur for select * from &tbl_nm;How can i do that??
Thank you

I assume you are using SQL*Plus:

Ref Cursor Output

Hi,
the I have the following procedure with an ref cursor as an output.
CONCERN_ID_PK -- CONCERN_ID_FK -- ECN_ID_PK -- ECN_NO
315 -- 315 -- 87 -- 4711
i must store the values in variable like
p_concern_id_pk
p_concern_id_fk
p_ecn_id_pk
p_ecn_no
because i want to call with the parameter an update procedure or/and an delete procedure.
The select into statement doesn't work with an ref cursor I read.
so what can be the solution for the problem ?
I also have a types packes with the definief ref cursor
type all_ecns is recursor;
Must I use an self defined Object type or object table ????
the procedures follows
p_concern_id_pk in concern.concern_id_pk%TYPE,
p_ecn_id_pk in ecn.ecn_id_pk%TYPE,
p_ecncursor out types.all_ecns
AS
BEGIN
OPEN p_ecncursor for select concern_id_pk, concern_id_fk, ecn_id_pk, ecn_no
from ecn e,
concern c
where e.concern_id_fk = p_concern_id_pk
and c.concern_id_pk = e.concern_id_fk
and c.active = 1
and ecn_id_pk = p_ecn_id_pk
and c.active = 1;
END;
Thanks Marcel

Is it something like this you're looking for?
PACKAGE TYPES IS
type tr is record (col1 tab1.col1%type, col2 tab1.col2%type);
type tc is ref cursor returning tr;
END;
PROCEDURE get_data(p_cursor out types.tc) IS
BEGIN
open p_cursor for select col1,col2 from tab1;
END;
PROCEDURE process_data(p_cursor in types.tc)
v_tr types.tr;
BEGIN
LOOP
fetch p_cursor into v_tr;
exit when p_cursor%notfound;
dbms_output.put_line(v_tr.col1||' '||v_tr.col2);
END LOOP;
close p_cursor;
END;

Call to Oracle stored procedure that returns ref cursor doesn't work

I'm trying to use an OData service operation with Entity Framework to call an Oracle stored procedure that takes an number as an input parameter and returns a ref cursor. The client is javascript so I'm using the rest console to test my endpoints. I have been able to successful call a regular Oracle stored procedure that takes a number parameter but doesn't return anything so I think I have the different component interactions correct. When I try calling the proc that has an ref cursor for the output I get the following an error "Invalid number or type of parameters". Here are my specifics:
App.config
<oracle.dataaccess.client>
<settings>
<add name="PGDATA_WC.ODATAPOC.GETWORKORDERSBYWINDFARMID.RefCursor.P_RESULTS" value="implicitRefCursor bindinfo='mode=Output'" />
<add name="PGDATA_WC.ODATAPOC.GETWORKORDERSBYWINDFARMID.RefCursorMetaData.P_RESULTS.Column.0" value="implicitRefCursor metadata='ColumnName=WINDFARM_ID;BaseColumnName=WINDFARM_ID;BaseSchemaName=PGDATA_WC;BaseTableName=WORKORDERS;NATIVEDATATYPE=Number;ProviderType=Int32'" />
<add name="PGDATA_WC.ODATAPOC.GETWORKORDERSBYWINDFARMID.RefCursorMetaData.P_RESULTS.Column.1" value="implicitRefCursor metadata='ColumnName=STARTTIME;BaseColumnName=STARTTIME;BaseSchemaName=PGDATA_WC;BaseTableName=WORKORDERS;NATIVEDATATYPE=Varchar2;ProviderType=Varchar2'" />
<add name="PGDATA_WC.ODATAPOC.GETWORKORDERSBYWINDFARMID.RefCursorMetaData.P_RESULTS.Column.2" value="implicitRefCursor metadata='ColumnName=ENDTIME;BaseColumnName=ENDTIME;BaseSchemaName=PGDATA_WC;BaseTableName=WORKORDERS;NATIVEDATATYPE=Varchar2;ProviderType=Varchar2'" />
<add name="PGDATA_WC.ODATAPOC.GETWORKORDERSBYWINDFARMID.RefCursorMetaData.P_RESULTS.Column.3" value="implicitRefCursor metadata='ColumnName=TURBINE_NUMBER;BaseColumnName=TURBINE_NUMBER;BaseSchemaName=PGDATA_WC;BaseTableName=WORKORDERS;NATIVEDATATYPE=Varchar2;ProviderType=Varchar2'" />
<add name="PGDATA_WC.ODATAPOC.GETWORKORDERSBYWINDFARMID.RefCursorMetaData.P_RESULTS.Column.4" value="implicitRefCursor metadata='ColumnName=NOTES;BaseColumnName=NOTES;BaseSchemaName=PGDATA_WC;BaseTableName=WORKORDERS;NATIVEDATATYPE=Varchar2;ProviderType=Varchar2'" />
<add name="PGDATA_WC.ODATAPOC.GETWORKORDERSBYWINDFARMID.RefCursorMetaData.P_RESULTS.Column.5" value="implicitRefCursor metadata='ColumnName=TECHNICIAN_NAME;BaseColumnName=TECHNICIAN_NAME;BaseSchemaName=PGDATA_WC;BaseTableName=WORKORDERS;NATIVEDATATYPE=Varchar2;ProviderType=Varchar2'" />

OData Service Operation:
public class OracleODataService : DataService<OracleEntities>
// This method is called only once to initialize service-wide policies.
public static void InitializeService(DataServiceConfiguration config)
// TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc.
// Examples:
config.SetEntitySetAccessRule("*", EntitySetRights.All);
config.SetServiceOperationAccessRule("GetWorkOrdersByWindfarmId", ServiceOperationRights.All);
config.SetServiceOperationAccessRule("CreateWorkOrder", ServiceOperationRights.All);
config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2;
[WebGet]
public IQueryable<GetWorkOrdersByWindfarmId_Result> GetWorkOrdersByWindfarmId(int WindfarmId)
return this.CurrentDataSource.GetWorkOrdersByWindfarmId(WindfarmId).AsQueryable();
[WebGet]
public void CreateWorkOrder(int WindfarmId)
this.CurrentDataSource.CreateWorkOrder(WindfarmId);
Here is the stored procedure:
procedure GetWorkOrdersByWindFarmId(WINDFARMID IN NUMBER,
P_RESULTS OUT REF_CUR) is
begin
OPEN P_RESULTS FOR
select WINDFARM_ID,
STARTTIME,
ENDTIME,
TURBINE_NUMBER,
NOTES,
TECHNICIAN_NAME
from WORKORDERS
where WINDFARM_ID = WINDFARMID;
end GetWorkOrdersByWindFarmId;
I defined a function import for the stored procedure using the directions I found online by creating a new complex type. I don't know if I should be defining the input parameter, WindfarmId, in my app.config? If I should what would that format look like? I also don't know if I'm invoking the stored procedure correctly in my service operation? I'm testing everything through the rest console because the client consuming this information is written in javascript and expecting a json format. Any help is appreciated!

Making the change you suggested still resulted in the same Oracle.DataAccess.Client.OracleException {"ORA-06550: line 1, column 8:\nPLS-00306: wrong number or types of arguments in call to 'GETWORKORDERSBYWINDFARMID'\nORA-06550: line 1, column 8:\nPL/SQL: Statement ignored"} System.Exception {Oracle.DataAccess.Client.OracleException}
I keep thinking it has to do with my oracle.dataaccess.client settings in App.Config because I don't actually put the WindfarmId and an input parameter. I tried a few different ways to do this but can't find the correct format.

Problem using REF CURSOR in JDBC

i have several stored procedures and functions that return REF CURSOR object as output. however, i'm noticing that if
no rows are returned within the cursor, the JDBC driver is throwing a "No more data to read from socket" exception.
i'm using the Oracle Thin JDBC driver v8.1.6 for JDK 1.2.
any help is appreciated.
thanks,

I am not able to reproduce the problem. Could you post a testcase so that we can follow it up?
Thanks.

How to call a Stored Procedure with a REF CURSOR output parameter

I am looking forward an example that call a stored function/procedure with a REF CURSOR output parameter and get the result.
In other words, I have a stored function/procedure that execute a SELECT statement using the OCI library and then it could get the values of each column and each row.
I put a code snippet, it have only the main thing to call a simple stored procedure and print the name of each column of the cursor, but I couldn´t to print out the values in the table that call the stored procedure.
I understand that the next step, it is to call a OCIStmtFetch.
How to associate the cursor with the OCIStmtFetch?
If you need more information, only tell me.
I am using ANSI C with HP-UX Operative System (C for HP-UX) and Oracle 10g.
Regards.

Hi Mark,
Thanks for your recommendations.
I change the code with OCIDefineByPos, one for each parameter from cursor and then use the OCIStmtFetch.
I don´t receive a error when call OCIDefineByPos, but when I call OCIStmtFetch receive a -1 error number.
What is wrong with the code?
The script is the same.
I need your help!
Best Regards!

Dispalying output from a REF CURSOR

Friends,
I'm getting my self into indepth pl/sql and need some help from you to clear some basic concepts.
create table MASTER_TABLE
street_info varchar2(100),
property_type varchar2(50) ------- i.e values here would be 'HOME_TABLE' ,'COM_PROP_TABLE' etc
create table HOME_TABLE
property_id char(5),
prop_desc varchar2(100),
cost varchar2(10),
location varchar2(100)
create table COM_PROP_TABLE
property_id char(5),
prop_desc varchar2(100),
cost varchar2(10),
location varchar2(100)
I want to use a single procedure to open a weak REF CURSOR variable for the appropriate table based on the street address and display all information from that table.
Here is what I want to to - execute a stored procedure which accepts 1 'in' paramter and 1 'in out ' parameter.
IN paramter - accepts street address
IN OUT paramter - depending on address , if it is related to 'Homes' , it should display all information from the HOME Table, else it will display information from the 'Commerical Property' table.
create or replace package pack_address_info as
type v_info_type ref cursor;
end pack_address_info;
create or replace procedure schema.sp_home_info(v_add in varchar2,v_show in out v_info_type)
is
home_type constant integer :=1;
commercial_type constant integer :=2;
cursor show_data_cur is
select property_type from MASTER TABLE where street_info=v_add;
var_cursor show_data_cur%rowtype;
begin
open show_data_cur;
fetch show_data_cur into var_cursor;
close show_data_cur;
if var_cursor.property_type= HOME_TABLE
then
open v_show for
select * from HOME_TABLE where location=v_add;
elseif var_cursor.table_name = COM_PROP_TABLE
then
open v_show for
select * from COM_PROP_TABLE where location=v_add;
end if;
end schema.sp_home_info;
I can create the package and the stored proc ... but then ???? i'm stuck ;(
Now , i don't know how to display the output from the HOME TABLE or the COM_PROP_TABLE depending on what the address is entered? Is this code correct. Can you please help me modify this code so that I can achieve my objective.
This is an example from the book 'Oracle PL/SQL Programming, 4th Edition' under the 'CURSOR' section - 15.6
Thanks for the help in advance.

Here is one sample ->

How to divide resultset of a query in different ref cursors in a package

Hi Oracle Gurus,
I need to create a package which counts the no of rows returned by a select query on multiple tables and according to the returned rowcount inputs the resultset in a ref cursor. Procedure will be called by a .NET program and output param refcursor will be assigned to a data reader which will redirect all the data to an Excel file.
All the above is done. Issue is due to Excel's limit of 64000 rows, if data returned by query is greater than 64K it wont be fit in 1 Excel sheet. So, in order to overcome this limit I need to do some looping in Oracle package which keeps on storing the query results (rows<64K) in different ref cursors so that these refcursors as OUT params can be redirected to separate Excel sheets in C# program.
NOTE : Earlier on I created 2 procedures in the package to fetch rows<64K and another one to fetch rows between 64K and rowcount of the query. My program was calling 2 different procedures to redirect data into 2 diff Excel sheets.
But this fails when query resultset is even greater than 128000 or more and demands 3-4 or even more Excel sheets to be created.
Please help.
Any idea how to do looping in Oracle to accomplish this?

Huh?
That is saying that "I need to change this road and build it straight through that lake as the road has a curve here".
It surely is a LOT easier to leave the road as is and simply turn the darn steering wheel in the car?
Have the .Net data reader keep a row count of rows read from the ref cursor - and when it reached a pre-set max, have the reader do a "control break"[1] and change to a new worksheet as the destination for writing the rows to.
[1] Google the term if you do not understand this basic concept that was among the very basic program control structures taught back in the 80's.. while I foam at the mouth how today's "wonder kids" turned programmers, that grew up with computers, do not even comprehend the most basic programming logic designs...

Got my REF CURSOR, how to output?
