How to use bulk insert in utl_file

i am creating text file of employee list i go huge data i want to use bulk insert with utl_file is it possible if so, how pls help me.

If what you are asking, in some unknown version of Oracle, is whether using FORALL will increase the speed for writing a file to your hard disk the answer is no.
BULK COLLECT, however, might help.

This isn't what you asked, but I've generally found it helpful to list the columns in an INSERT statement before the values. It is of course optional, but useful for reference when looking at the statement later

Is there a way to dynamically figure out the FIRSTROW & LASTROW using Bulk Insert?

I noticed most of my files follow a certain convention, so I can use Bulk Insert with this:
FIRSTROW = 2, LASTROW = 224
However a few files have many more records. I'd like SQL Server to dynamically figure out the first and last rows with data, but I don't know if that's possible. Can someone confirm?
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

Nope, you would need read the files from some program. Could be a CLR stored procedure if you want to do it from SQL Server. But from BULK INSERT alone, no.

If your database in Full Recovery mode, can you use Bulk Insert Task to load data

If your database in Full Recovery mode, can you use Bulk Insert Task to load data

If your database in Full Recovery mode, can you use Bulk Insert Task to load data
Yes you can ofourse but dont be in idea that logging will be mininal. Loggign will be as per recovery model full. Every thing will be logged. If you are going to use bulk insert task you can consider switching recovery model to Bulk logged but you will not
have option to do point in time recovery.
PS: please dont create duplicate threads
If you read first Note section in below link it clearly states that yes logging will be full and you can use

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,
order_type,

order_date,
attribute1,
market,
processed_flag,
last_update_date
BULK COLLECT INTO imei_ntt
FROM (SELECT 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
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;

-- 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

                         FORALL k in 1.. Job_history_data.COUNT LOOP
                                        -- insert into FILE C
                                          INSERT INTO MY_TEST(employee_id, first_name, last_name, hire_date, job_id)

Thank you for your guidance,

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

Using Bulk insert or SQL Loader in VB6

Hi,
I am quite new to the Oracle world and also forums. But I am looking for some directions in how i get a dataset of 10000 records into a table the quickest way. I have the recordset in an ADO Recordset (or a textfile if that is easier) and I want to insert them in an empty Oracle table. The problem is - I don't know how to.
Situation
The Oracle DB is on another computer I have nothing special installed on the computer running the VB6 application.
Can anyone please provide code example or guidelines...
Regards,
Christian

This may not be "bulk insert" by your definition, but it can transfer data as you want.
A simple VB code for demo purpose:
Dim con As New ADODB.Connection
Dim con2 As New ADODB.Connection
Dim rst As New ADODB.Recordset
Dim rst2 As New ADODB.Recordset
Dim rst3 As New ADODB.Recordset
con.ConnectionString = "Provider=OraOLEDB.Oracle.1;User ID=scott;Password=tiger;Data Source=db_one;"
con.Open
rst.Open "select * from dept", con, adOpenDynamic, adLockOptimistic
'save to a file using ADTG format. You may choose other format.
rst.Save "c:\myfile.txt", adPersistADTG
'dept2 is an empty table with the same table definition as dept. You can create it using SQL*Plus.
'add rows by reading from the saved file.
con2.ConnectionString = "Provider=OraOLEDB.Oracle.1;User ID=xyz;Password=xyz;Data Source=db_two;"
con2.Open
'open the saved file
rst2.Open "c:\myfile.txt"
'rst3 is an empty recordset because dept2 is empty at this time.
rst3.Open "select * from dept2", con2, adOpenDynamic, adLockOptimistic
'adding rows into dept2.
Do Until rst2.EOF
rst3.AddNew Array("deptno", "dname", "loc"), Array(rst2.Fields("deptno"), rst2.Fields("dname"), rst2.Fields("loc"))
rst2.MoveNext
Loop
rst.Close
rst2.Close
rst3.Close
con.Close
con2.Close

How to change Bulk Insert statement from MS SQL to Oracle

Hi All,
Good day, I would like to bulk insert the content of a file into Oracle db. May I know how to change the below MS SQL syntax to Oracle syntax?
Statement statement = objConnection.createStatement();
statement.execute("BULK INSERT [TBL_MERCHANT] FROM '" MERCHANT_FILE_DIR "' WITH ( FIELDTERMINATOR = '~~', ROWTERMINATOR = '##' )");
Thanks in advance.

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 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 debug bulk insert?

I have this code which doesn't cause any error, and actually gives message 'query executed successfully', but it doesn't load any data.
bulk insert [dbo].[SPGT]
from '\\sys.local\london-sql\FTP\20140210_SPGT.SPL'
WITH (
KEEPNULLS,
FIRSTROW=5,
FIELDTERMINATOR='\t',
ROWTERMINATOR='\n'
How can I debug the issue, or see what the script is REALLY doing? It's not doing what I think it's doing.
All permissions, rights, etc are setup correctly. I just run the code successfully with a .txt file. Maybe it has something to do with the extension...
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

Yes, here is the final solution (for the benefit of others who find this anytime in the future).

This was a bit confusing at first, because I've never done it before, and also, I was getting all kinds of errors, which turned out to be numbers in string fields and strings in number fields. Basically, the data that was given to me was totally screwed
up. That compounded the problem exponentially. I finally got the correct data, and I'm all set now.
Thanks everyone!

How to use BULK COLLECT in ref cursor?

hi,
can we use bulk collect in ref cursor ? if yes then please give small example ..
thanks

Try this:
create or replace type person_ot as object (name varchar2(10)) not final;
create or replace type student_ot under person_ot (s_num number) not final;
create type person_tt as table of person_ot;
create table persons of person_ot;

select new student_ot(''sally'', 200) from dual';
open ref_cur for lv_sql;
fetch ref_cur bulk collect into lv_person_list;
close ref_cur;
for i in lv_person_list.first..lv_person_list.last loop

File access problem while using BULK INSERT

I'm creating a script to automatically convert a large mess of data. Here's a test query I was using to bring a file into the database:
INSERT [ImportTestTable]
SELECT a.*
FROM
OPENROWSET(
BULK 'D:\TestFile.csv',
FORMATFILE = 'D:\TestStyle.fmt',
FIRSTROW = 2
) AS a;
SELECT * FROM ImportTestTable
I've used queries like this on other networks and machines before, but when I run that query on the particular machine I'm working with now, I get the following error:
Msg 4861, Level 16, State 1, Line 13
Cannot bulk load because the file "D:\TestFile.csv" could not be opened. Operating system error code 21
(The device is not ready.).
Here's some relevant facts I can think of that might help:
I am running the query from SQL Server Management Studio on a remote machine running Windows 7 Ultimate. I am connected to this server using SQL authentication. I believe we are on the same domain / network. I am not the DBA. I do
have the permission "Administer Bulk Operations" explicitly granted to me by the DBA. The user I am currently logged in as in windows is capable of opening, editing, and saving the file in windows explorer. The format file is a NON-XML
format file.
Any pointers as to where to look for more detailed information would be greatly appreciated!

I know this is a little old by now, but this is what I used just this week:
bulk insert [dbo].[Test_Table]
from 'C:\Documents and Settings\rshuell\Desktop\Test_File.txt'
WITH (
FIELDTERMINATOR=',',
ROWTERMINATOR = '\n',
KEEPNULLS,
FIRSTROW=2
That worked fine for me.
Of course, we Naomi stated, the file has to be ON THE SERVER. Or, if you're using an FTP site, for instance, the path would have to point to the FTP site.
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

How to use bulk collect into clause

hi all,
i have requirement like this i want to change the query by passing the different table names in oracle database 10gr2.
like if i use first i pass the scott.emp table name select * from scott.emp;
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 bulk in multiple cursors !!

Hello All,
I am having a following program that perfectly runs but its taking very huge time to complete it.
Can any one suggest how i can improve the performace of this code ..
thanks in advance - appreciate your help .
Here's the program.
==============
procedure Proc_Fmly_VehicleTA_Cnt is
CURSOR c_cur_fmly IS SELECT FAMID, NUM_AUTO, NUM_TVAN, VEHQ, VEHQL FROM FMLY;

btw your exception handler has a couple of problems (I've formatted it for you):
EXCEPTION
   WHEN OTHERS THEN
      RAISE_APPLICATION_ERROR
      ( -20001, 'An error was encountered - '||SQLCODE||' -ERROR- '||SQLERRM );
      v_err_code := SQLCODE;
      v_err_msg := SUBSTR(SQLERRM, 1, 200);
      INSERT INTO audit_table (error_number, error_message) VALUES (v_err_code, v_err_msg);
      error_logging
      ( p_error_code => substr(sqlerrm,1,9)
      , p_error_message => substr(sqlerrm,12)
      , p_package => 'PKG_FCI_APP'
      , p_procedure => 'Proc_Fmly_VehicleTA_Cnt'
      , p_location => v_location ); When RAISE_APPLICATION_ERROR raises the exception, the procedure will terminate and the error logging steps below it won't get called.
Also if you just want to re-raise an exception without adding any information or your own message etc, then you should use RAISE, not RAISE_APPLICATION_ERROR. If you're going to use RAISE_APPLICATION_ERROR it should be something like:
RAISE_APPLICATION_ERROR
( -20001
, 'Could not set automobile count to ' || v_total_automobiles || ' for family ' || i.famid
, TRUE );Notice the last parameter, TRUE, which tells it to keep the existing error stack (i.e. whatever Oracle error made it fail), which will then appear underneath your custom error message. You should never concatenate SQLERRM into a RAISE_APPLICATION_ERROR message. (And SQLCODE is just the error number that is already part of SQLERRM so there is no point including that anyway.)
Those changes give you something like:
EXCEPTION
   WHEN OTHERS THEN
      INSERT INTO audit_table (error_number, error_message)
      VALUES (SQLCODE, SUBSTR(SQLERRM,1,200)); -- btw why SUBSTR? Why not log the entire message?
      error_logging
      ( p_error_code => substr(sqlerrm,1,9)
      , p_error_message => substr(sqlerrm,12)
      , p_package => 'PKG_FCI_APP'
      , p_procedure => 'Proc_Fmly_VehicleTA_Cnt'
      , p_location => v_location );
      RAISE_APPLICATION_ERROR
      ( -20001
      , 'Could not set automobile count to ' || v_total_automobiles || ' for family ' || i.famid
      , TRUE );
