Please help meIt's correct. The SQL engine cannot access type structures you declare in PL/SQL code. It's like asking one program to go and hack into another program's memory and understand the structures it uses for it's datatypes. SQL and PL/SQL are two seperate processes. SQL can only understand datatypes that can be created as database objects.

I Don't know how to use SBO Transaction Notification procedure

Hi all
I don't know how to use SBO Transaction Notification procedure
can any body give me description why we use,where we use,how we use some example
Awaiting soon reply
Rajkumar G.

example is for testing, if on delivery is filled ref no of vendor or not
if @object_type = '20' and (@transaction_type= 'A' or @transaction_type= 'U')
begin
     if 1 = (select count(docentry) from opdn with(nolock) where docentry =@list_of_cols_val_tab_del and (numatcard is null or len(numatcard) = 0) )
     begin
          select @error =1
          select @error_message = 'vendor ref no isnt filled'
     end
end
next example is for creating BP as vendor and testing, if dont begin for specific sign
if @object_type = '2' and @transaction_type= 'A'
begin
if left(@list_of_cols_val_tab_del, 1) = N'x' or left(@list_of_cols_val_tab_del, 1) = N'X'
     begin
          if 1 = (select count(cardcode) from ocrd where cardcode = @list_of_cols_val_tab_del and cardtype in ('S', N'S') )
               begin
     select @error =1
          select @error_message = 'Vendor code cannot begin to X sign.'
end
     end

How to use BULK COLLECT in oracle forms

hi gurus,
I am using oracle forms
Forms [32 Bit] Version 10.1.2.0.2 (Production)
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - ProductionI wanna use bulk collect from database table lets say <employees>
while working on database level with collections and records it's working very well for me, but when I try to use that technique on oracle forms it hits me error
error 591 this feature is not supported in client side programmingI know I can use cursors to loop through the records of oracle tables ,
but I'm convenient while using collections and arrays
for example
Set Serveroutput On
Declare
      Type Rec_T Is Record (
       Empid Number ,
       Empname Varchar2(100)
      Type V_R Is Table Of Rec_T Index By Binary_Integer;
      V_Array V_R;
Begin
   Select Employee_Id , First_Name
   Bulk Collect
   Into V_Array
      From Employees;
   For Indx In V_Array.First..V_Array.Last Loop
   Dbms_Output.Put_Line('employees id '||V_Array(Indx).Empid ||'and the name is '||V_Array(Indx).Empname);
   End Loop;
     End;I wanna use this same way on oracle forms , for certain purposes , please guide me how can I use ...
thanks...

For information, you can use and populate a collection within the Forms application without using the BULK COLLECT
Francoisactually I want to work with arrays , index tables ,
like
         record_type (variable , variable2);
         type type_name <record_type> index by binary_integer
        type_variable type_name;
        and in main body of program
        select something
        bulk collect into type_variable
        from any_table;
       loop
            type_variable(indx).variable , type_variable(indx).variable2;
       end loop;
       this is very useful for my logic on which I am working
          like
          type_variable(indx).variable || type_variable(indx-1);
         if it's possible with cursors then how can I use cursor that can fullfill my this logic@Francois
if it's possible then how can i populate without using bulk collect?
thanks
and for others replies: if I can use stored procedures please give me any example..
thanks

How to use BULK COLLECT, FORALL and TREAT

There is a need to read match and update data from and into a custom table. The table would have about 3 millions rows and holds key numbers. BAsed on a field value of this custom table, relevant data needs to be fetched from joins of other tables and updated in the custom table. I plan to use BULK COLLECT and FORALL.
All examples I have seen, do an insert into a table. How do I go about reading all values of a given field and fetching other relevant data and then updating the custom table with data fetched.
Defined an object with specifics like this
CREATE OR REPLACE TYPE imei_ot AS OBJECT (
recid NUMBER,
imei VARCHAR2(30),
STORE VARCHAR2(100),
status VARCHAR2(1),
TIMESTAMP DATE,
order_number VARCHAR2(30),
order_type VARCHAR2(30),
sku VARCHAR2(30),
order_date DATE,
attribute1 VARCHAR2(240),
market VARCHAR2(240),
processed_flag VARCHAR2(1),
last_update_date DATE
Now within a package procedure I have defined like this.
type imei_ott is table of imei_ot;
imei_ntt imei_ott;
begin
SELECT imei_ot (recid,
imei,
STORE,
status,
TIMESTAMP,
order_number,

last_update_date
BULK COLLECT INTO imei_ntt

co.rtl_txn_timestamp, co.rtl_order_number, 'CUST',
msi.segment1 || '.' || msi.segment3,
TRUNC (co.txn_timestamp), col.part_number, 'ZZ',
stg.processed_flag, SYSDATE
FROM custom_orders co,
custom_order_lines col,
custom_stg stg,
mtl_system_items_b msi
WHERE co.header_id = col.header_id
AND msi.inventory_item_id = col.inventory_item_id
AND msi.organization_id =
(SELECT organization_id
FROM hr_all_organization_units_tl
WHERE NAME = 'Item Master'
AND source_lang = USERENV ('LANG'))
AND stg.imei = col.serial_number
AND stg.processed_flag = 'U');
/* Update staging table in one go for COR order data */
FORALL indx IN 1 .. imei_ntt.COUNT
UPDATE custom_stg
SET STORE = TREAT (imei_ntt (indx) AS imei_ot).STORE,
status = TREAT (imei_ntt (indx) AS imei_ot).status,
TIMESTAMP = TREAT (imei_ntt (indx) AS imei_ot).TIMESTAMP,
order_number = TREAT (imei_ntt (indx) AS imei_ot).order_number,
order_type = TREAT (imei_ntt (indx) AS imei_ot).order_type,
sku = TREAT (imei_ntt (indx) AS imei_ot).sku,
order_date = TREAT (imei_ntt (indx) AS imei_ot).order_date,
attribute1 = TREAT (imei_ntt (indx) AS imei_ot).attribute1,
market = TREAT (imei_ntt (indx) AS imei_ot).market,
processed_flag =
TREAT (imei_ntt (indx) AS imei_ot).processed_flag,
last_update_date =
TREAT (imei_ntt (indx) AS imei_ot).last_update_date
WHERE recid = TREAT (imei_ntt (indx) AS imei_ot).recid
AND imei = TREAT (imei_ntt (indx) AS imei_ot).imei;
DBMS_OUTPUT.put_line ( TO_CHAR (SQL%ROWCOUNT)
|| ' rows updated using Bulk Collect / For All.'
EXCEPTION
WHEN NO_DATA_FOUND
THEN
DBMS_OUTPUT.put_line ('No Data: ' || SQLERRM);
WHEN OTHERS
THEN
DBMS_OUTPUT.put_line ('Other Error: ' || SQLERRM);
END;
Now for the unfortunate part. When I compile the pkg, I face an error
PL/SQL: ORA-00904: "LAST_UPDATE_DATE": invalid identifier
I am not sure where I am wrong. Object type has the last update date field and the custom table also has the same field.
Could someone please throw some light and suggestion?
Thanks
uds

I suspect your error comes from the »bulk collect into« and not from the »forall loop«.
From a first glance you need to alias sysdate with last_update_date and some of the other select items need to be aliased as well :
But a simplified version would be
select imei_ot (stg.recid,
                stg.imei,
                cip.store_location,
                'S',
                co.rtl_txn_timestamp,
                co.rtl_order_number,
                'CUST',
                msi.segment1 || '.' || msi.segment3,
                trunc (co.txn_timestamp),
                col.part_number,
                'ZZ',
                stg.processed_flag,
                sysdate
bulk collect into imei_ntt
from custom_orders co,
       custom_order_lines col,
       custom_stg stg,
       mtl_system_items_b msi
where co.header_id = col.header_id
   and msi.inventory_item_id = col.inventory_item_id
   and msi.organization_id =
              (select organization_id
                 from hr_all_organization_units_tl
                where name = 'Item Master' and source_lang = userenv ('LANG'))

How to use Bulk Collect and Forall

Hi all,
We are on Oracle 10g. I have a requirement to read from table A and then for each record in table A, find matching rows in table B and then write the identified information in table B to the target table (table C). In the past, I had used two ‘cursor for loops’ to achieve that. To make the new procedure, more efficient, I would like to learn to use ‘bulk collect’ and ‘forall’.
Here is what I have so far:
DECLARE
TYPE employee_array IS TABLE OF EMPLOYEES%ROWTYPE;
employee_data employee_array;
TYPE job_history_array IS TABLE OF JOB_HISTORY%ROWTYPE;
Job_history_data   job_history_array;
BatchSize CONSTANT POSITIVE := 5;
-- Read from File A
CURSOR c_get_employees IS
         SELECT Employee_id,
                   first_name,
                   last_name,
                   hire_date,
                   job_id
          FROM EMPLOYEES;
-- Read from File B based on employee ID in File A
CURSOR c_get_job_history (p_employee_id number) IS
         select start_date,
                  end_date,
                  job_id,
                  department_id
         FROM JOB_HISTORY
         WHERE employee_id = p_employee_id;
BEGIN
    OPEN c_get_employees;
    LOOP
        FETCH c_get_employees BULK COLLECT INTO employee_data.employee_id.LAST,
                                                                          employee_data.first_name.LAST,

Thank you for your guidance,
Seyed

Hello BlueShadow,
Following your advice, I modified a stored procedure that initially was using two cursor for loops to read from tables A and B to write to table C to use instead something like your suggestion listed below:
INSERT INTO tableC
SELECT …
FROM tableA JOIN tableB on (join condition).I tried this change on a procedure writing to tableC with keys disabled. I will try this against the real table that has primary key and indexes and report the result later.
Thank you very much,
Seyed

How to use same collection type in different database

i have created a synonym for a package whcih uses a collection type as input and when i am calling through that synonym it is throwing an error b'coz of the collection type saying wrong no. of arguements...
declare
collection_type collection_type:=collection_type('value');
begin
package_synonym1.procedure1(collection_type);
END;
how to rectify it can someone suggest....
a quick response would be highly appreciated

i have a package in schema A in which my input in a procedure is of type
like
create or replace package abc as
procedure efg (
ptbl_service_id in tbl_input_list,
pn_error_code_out OUT NUMBER,
pv_error_msg_out OUT VARCHAR2
and in schema A the type is created.the package is working fine
but when i am trying to test this package from database b with script as
declare
xyz tbl_input_list :=tbl_input_list('abcdefgh');
begin
abc.efg(
xyz,
pn_error_code_out,
pv_error_msg_out
end;
then it gives an error saying wrong no. of arguements ORA-06550
I have created the type in this database with the same OID as well and i have also tried the option of creating a synonym or calling it through a database link...
Is there any other way through which we can use it.....
A Quick Response will be highly appreciated...

How to use BULK COLLECT in Oracle Forms 11g

Forms is showing error that "Feature is not support in Client Side Program" when i am trying to impliment Bulk collect in Forms 11g.
i need to load full data from DB to my form becuase using cursor is very slow....
Is there any method/Work around to achieve this ....

declare
type arr is table of emp%rowtype ;
lv_arr arr;
begin
select * bulk collect in to lv_arr from emp;
/*written code here to process the data and write in to file*/
end;Unless you are inserting/updating the data you are holding in the array into a database table I don't think there is much peformance gain in using bulk-collect in conjunction with writing a file. Bulk processing will increase performance by minimizing context switches from the SQL to the PL/SQL engine, nothing more, nothing less.
In any case bulk processing is not available in forms, if you really need to make use of it you need to do it in a stored procedure.
cheers

How to use arrays in stored procedure??Please do help me.......

hi, i need to make a procedure where i may execute a query.The query returns multiple rows.Now i want to use 1 row.i needs to fetch all colums as out parameter...can anyone please help me.....i will be very thankful to the person.

you cannot just force only one column from a select statement to be a out parameter, you need to collect all the columns into a collection type and use the collection type as out parameter or use refcursor as out parameter and fetch the rows
using collection type
create type obj_typ is object(
a_val number,
b_val varchar2(100)
create type nest_typ is table of obj_typ
create or replace procedure retrieve_emp(mgr_no number,e_details out nest_typ) is

where mgr = mgr_no;

How to use same collection on two forms

Hi ,
My issue scenerio is--
I have two forms one is calling form other is call form. User will go to calling form and press button to open call form. In call form user will select some records. That records i want to store in collection. then user will close call form , and on calling form i want to use those collection values.
For this i did some coding like
I created a type in database , then I created a record type in which i stored selected records information. I can see that values have been properly stored in collection till i exit call form.
Once i am back on calling form it becomes null.
Please help..
Regards,
Kuldeep

*Before posting on this forum please read*

then i want pass scott.dept table name select * from scott.dept;
using select * option in the select list.
how can i execute it.
give me any solution.
please reply....

Hi,
i recently also ran into some serious trouble to make dynamic sql work.
It was about parallel pipelined function with strongly typed cursor (for "partition ... by hash(...)").
But in addition requiring dynamic SQL for the input to this cursor.
I couldn't make it work with execute immediate or something else.
So i used another way - I translated dynamic SQL into dynamically created static SQL:
1. create a base SQL data object type with abstract interface for code (e.g. some Execute() member function).
2. dynamically create a derived SQL data object type with concrete implementation of Execute() holding your "dynamic SQL" "in a static way"
3. delegate to Execute().
Let me quote my example from comp.databases.oracle.server, thread "dynamically created cursor doesn't work for parallel pipelined functions"
- pls. see below (it's an old one - with likely some odd stuff inside).
It might sound some kind of strange for DB programmer.
(I come from C++. Though this is not an excuse smile)
Maybe i just missed another possible option to handle the problem.
And it's a definitely verbose.
But i think it's at least a (last) option.
Actually i would be interested to hear, what others think about it.
best regards,
Frank

How to use a collection type of bind variable for execute dynamic statement

Hi,
We have a case where we copy selective data from Schema A To Schema B in one oracle database. The copy is achieved by using
execute immediate 'insert into '||target_schema||'.tablea select * from '||from_schema||'.table a where a.id in (select test_id from '||from_schema||'.table c);';
This works fine it takes an average of 10 seconds to copy around 14 tables. We have a requirement to bring this time to 2 seconds. One observation has been the clause
"select test_id from '||from_schema||'.table c" in the above sql statement repeats for many inserts . Thus we were thinking to bulk fetch this set of tests ids and use a bind vatiable of collection type for the execute immediate clause. Any suggestions on how to achieve it?
Thanks,
Chandana

So what? Constructing a string for a table level insert and parsing it can't possibly be a performance problem. If you were creating a string in a loop to insert rows into a table by getting the data FROM a collection - that's a problem that keeps showing up in the forums.
I'm with bravid and Nikolay on this one. First find out which side, select/insert, the problem is on.
As they said you need to provide more information about the process.
And using collections for your use case is definitely not the thing to do.
1. How many rows are we talking about?
2. Are the rows being inserted into an empty table?
3. Are you running these queries during peak production hours or in a batch windows?
Tune the SELECT if the problem is on that side.
Post an execution plan for the SELECT part of a query you think should run faster.
SET SERVEROUTPUT ON
SET AUTOTRACE TRACEONLY
SQL> select * from emp;
Execution Plan
Plan hash value: 3956160932
| Id | Operation         | Name | Rows | Bytes | Cost (%CPU)| Time     |
|   0 | SELECT STATEMENT |      |    14 |   546 |     3   (0)| 00:00:01 |
|   1 | TABLE ACCESS FULL| EMP |    14 |   546 |     3   (0)| 00:00:01 |
SQL>On the INSERT side you might be able to use bulk inserts
ALTER TABLE myTable NOLOGGING;
INSERT /*+ append */ INTO myTable . . .
ALTER TABLE myTable LOGGINGIf the insert tables are always reused you could just leave them as NOLOGGING. Since you can't recover bulk data you need to make sure to get a good backup after the loads if you need to recover the data from the logs rather than just reload it yourself.

How to use a collection as an input in web services?

Hi all,
I have to connect to a web service of an rfc sap, the RFC has the following structure:
- Input
   - parameters(parameters)
      - ZBAPI_SET_CG(ZBAPI_SET_CG)
         - V_DES_KOSTL(com.sap.caf.base.string)
         - V_DES_KSTAR(com.sap.caf.base.string)
-T_TEXT(TABLE_T_TEXT_TLINE)
- item(java.util.Collection - TLINE)
- TDFORMAT(com.sap.caf.base.string)
- TDLINE(com.sap.caf.base.string)
- Output....
How can I create such a collection as input?
Should I create a new operation or use existing ones? (read, create, update, delete, findbymultipleparameters, readbycustomkey)
thanks!!!

Hi Pablo,
Can you provide some more info?.
Which version are you using , CE 7.1 or NW 7.0?
If you are using CE 7.1:
If you want to invoke the Web Service from your project, Just import that web service and map it to an application service operation. You can go for default mapping.
if you want to go for Remote persitensy, then only you have to use CRUD(read, create, update, delete)
methodes of the Remote Business Objects.
Refer the [help documentation|http://help.sap.com/saphelp_nwce10/helpdata/en/45/174ae492ef5d79e10000000a11466f/content.htm].
