Bulk collect fresh limit clause
Hey,.There is little theoretical question about bulk collect.
Have searched a lot of books but could not get the right solution.
How do we calculate the value optimized for the fired limit bulk clause?
-Say we have 10 million records... What should be the optimized value of limit?
-We have 100 million documents... What should be the optimized value of limit?
My code woks strangely... I was wondering what would be the limit?
Value optimized in the Limit clause is equal tohow amount of memory you can afford to consume in the PGA and then adjust the limit to be as close to that amount as possible.
Use of the below block to check that limit what value would be the most appropriate for your system, since it depends of your allocation of memory and CPU consumption.
DECLARE
PROCEDURE fetch_all_rows (limit_in IN PLS_INTEGER)
IS
CURSOR source_cur
IS
SELECT *
FROM all_source;
TYPE source_aat IS TABLE OF source_cur%ROWTYPE
INDEX BY PLS_INTEGER;
l_source source_aat;
l_start PLS_INTEGER;
l_end PLS_INTEGER;
BEGIN
DBMS_SESSION.free_unused_user_memory;
show_pga_memory (limit_in || ' - BEFORE');
l_start := DBMS_UTILITY.get_cpu_time;
OPEN source_cur;
LOOP
FETCH source_cur
BULK COLLECT INTO l_source LIMIT limit_in;
EXIT WHEN l_source.COUNT = 0;
END LOOP;
CLOSE source_cur;
l_end := DBMS_UTILITY.get_cpu_time;
DBMS_OUTPUT.put_line ( 'Elapsed CPU time for limit of '
|| limit_in
|| ' = '
|| TO_CHAR (l_end - l_start)
);
show_pga_memory (limit_in || ' - AFTER');
END fetch_all_rows;
BEGIN
fetch_all_rows (1);
fetch_all_rows (5);
fetch_all_rows (25);
fetch_all_rows (50);
fetch_all_rows (75);
fetch_all_rows (100);
fetch_all_rows (1000);
fetch_all_rows (10000);
fetch_all_rows (100000);

Bulk Collect and limit the rows
Hello Oracles,
I feel a strange (at least to me) behavior with lines in BULK COLLECT and LIMIT.
For test purposes, I've written a procedure that uses a CURSOR, explicit AND implicit.
When I use the explicit CURSOR and the LOOP, I use BULK COLLECT and LIMIT lines.
I do not ROWNUM limit with my SELECT INTO. I know for a fact ROWNUM works very well since the last millennium.
When I look at the number of rows returned when I put the LIMIT, I get weird number of extractions...
I recover in a TABLE INDEX BY which is based on a TYPE of ENTRY.
Here are a few results with different LIMIT values for a small group of key PRIMARIES.
The figures below are the value of my_table . COUNTY
Any idea would be apreciated.

Example: If your cursor retrieves a total of 183 ranks with a maximum size of 100, then your loop steps through twice. The first single 100 lines, the second 83. You print only the last extraction and not the sum of all the extractions.

code is: cursor here can fetch a large amount of data (22000 records). So I have to go with the limit clause. I use two foralls. This code snippet is correct with regard to the two foralls, exit and % bulk_rowcount sql statement? I have to use in production. Is there something that can break the code?
OPEN c1;
LOOP
C1 FETCH BULK COLLECT WITHIN the limits of the 100 id_array;
FORALL i IN id_array. FIRST... id_array. LAST
Update statement;
BECAUSE me IN id_array. FIRST... id_array. LAST
LOOP
v_cnt: = v_cnt + SQL % BULK_ROWCOUNT (i);
END LOOP;
FORALL i IN id_array. FIRST... id_array. LAST
Insert statement;
WHEN id_array EXIT. COUNT = 0;
END LOOP;
CLOSE c1;
In addition, how context switching works when we use the llimit clause?
without limit:
collection is completely filled. then prepares to all the DML statements and go to sql and exeutes one by one.
right?
tasted clause say limit = 100
100 indexes collection gets populated.then prepares all the DML statements for these 100 indices and go to the DTF sql and exeutes. And then back to pl/sql. fills the same 100 indices collection with 100 records and prepares the DML and goes to sql to run and returns to pl/sql and so on? Is this true?
right?large volume of data (22000 records)
This isn't a large volume of data.
In addition, how context switching works when we use the llimit clause?

Doubt on bulk collect with LIMIT
Hello
I have a doubt on in bulk to collect, when did Commit
I have an example in PSOUG
http://psoug.org/reference/array_processing.html
If my table servers were 3 000 000 files, when do we commit? When I insert all records?CREATE TABLE servers2 AS SELECT * FROM servers WHERE 1=2; DECLARE CURSOR s_cur IS SELECT * FROM servers; TYPE fetch_array IS TABLE OF s_cur%ROWTYPE; s_array fetch_array; BEGIN OPEN s_cur; LOOP FETCH s_cur BULK COLLECT INTO s_array LIMIT 1000; FORALL i IN 1..s_array.COUNT INSERT INTO servers2 VALUES s_array(i); EXIT WHEN s_cur%NOTFOUND; END LOOP; CLOSE s_cur; COMMIT; END;
could crash redo log?
using 9.2.08muttleychess wrote:

Your code implements a commercial operation, right? So if you're getting into before any trancaction (from the commercial point of view) other sessions will be already see changes that are (from a business point of view) incomplete. In addition, what happens if rest of trancaction (from the commercial point of view) goes down?

Using bulk collect into with assistance from the limit to avoid the TEMP tablespace error run out?
Hi all
I want to know if using bulk collect into limit will help to avoid the TEMP tablespace error run out.
We use Oracle 11 g R1.
I am assigned to a task of creating journal facilitated for all tables in a query of the APEX.
I create procedures to execute some sql statements to create a DEC (Create table select), and then fires on these tables.
We have about three tables with more than 26 million records.
It seems very well running until we reached a table with more than 15 million record, we got an error says that Miss tablespace TEMP.
I googled on this topic and retrieve the tips:
Use NO LOG
Parallel use
BULK COLLECT INTO limited
However, the questions for those above usually short-term memory rather than running out of TEMPORARY tablespace.
I'm just a junior developer and does not have dealed with table more than 10 million documents at a time like this before.
The database support is outsourced. If we try to keep it as minimal contact with the DBA as possible. My Manager asked me to find a solution without asking the administrator to extend the TEMP tablespace.
I wrote a few BULK COLLECT INTO to insert about 300,000 like once on the development environment. It seems.
But the code works only against a 000 4000 table of records. I am trying to add more data into the Test table, but yet again, we lack the tablespace on DEV (this time, it's a step a TEMP data)
I'll give it a go against the table of 26 million records on the Production of this weekend. I just want to know if it is worth trying.
Thanks for reading this.

I really need check that you did not have the sizes of huge line (like several K by rank), they are not too bad at all, which is good!
A good rule of thumb to maximize the amount of limit clause, is to see how much memory you can afford to consume in the PGA (to avoid the number of calls to the extraction and forall section and therefore the context switches) and adjust the limit to be as close to that amount as possible.
Use the routines below to check at what threshold value would be better suited for your system because it depends on your memory allocation and CPU consumption. Flexibility, based on your limits of PGA, as lines of length vary, but this method will get a good order of magnitude.
CREATE OR REPLACE PROCEDURE show_pga_memory (context_in IN VARCHAR2 DEFAULT NULL)
IS
l_memory NUMBER;
BEGIN
SELECT st. VALUE

AND themselves. SID = st. SID
AND nm.NAME = 'pga session in memory. "
Dbms_output.put_line (CASE

Bulk collect treats all lines not containing the LIMIT clause.
Hi all
I was referring the Oracle Site for COLLECTION in BULK.
http://www.Oracle.com/technology/oramag/Oracle/08-Mar/o28plsql.html
In the following code, I found and I ran the same.
I just want to know why motor Pl - SQL is not processing or recital 27 last lines when I use % NOTFOUND cursot attribute.
Please guide me on this.PROCEDURE process_all_rows_foi_test (p_limit PLS_INTEGER DEFAULT 100) IS CURSOR c1 IS SELECT * FROM all_objects WHERE ROWNUM <= 227; TYPE foi_rec IS TABLE OF c1%ROWTYPE INDEX BY PLS_INTEGER; v_foi_rec foi_rec; v_number NUMBER := 1; BEGIN OPEN c1; LOOP FETCH c1 BULK COLLECT INTO v_foi_rec LIMIT p_limit; EXIT WHEN v_foi_rec.COUNT = 0;--------EXIT WHEN c1%NOTFOUND;--->Here is the issue DBMS_OUTPUT.put_line (v_number); v_number := v_number + 1; END LOOP; CLOSE c1; END;
Thank you
Arun% NOTFOUND will have the value TRUE when it gets below the limit
(it is documented)
But your workaround works fine

Hi all
I was reading [http://asktom.oracle.com/pls/apex/f?p=100:11:0:P11_QUESTION_ID:5918938803188] of Tom Kyte site on bulk collect within limits. The code uses the % notfound cursor to exit the recovery loop. What I do in this situation is using exists, method of table rather than cursor attribute.
Since when I do this:create or replace procedure p1 is type num_list_type is table of number index by pls_integer; num_list num_list_type; cursor c1 is select temp from test; begin open c1; loop fetch c1 bulk collect into num_list limit 2; if num_list.exists(1)=false then exit; end if; for i in num_list.first..num_list.last loop dbms_output.put_line(num_list(i)); END LOOP; end loop; end;
It will close when the cursor retrieves only less than the limit, leaving a few rows. If the code works properly.exit wen c1%notfound
Question:
1. is the Exit statement properly, is there another way (I'm a little skeptical because I'm not using the cursor)?
2 How to decide on the size limit based on what we have in the hardware settings and oracle? All of the guidelines?
3 - is the best practice when it comes with the cursor and several lines that still use bulk collect into?
Best regards

ValHello
1. Yes, in above code statement EXIT will work correctly. The other way is % NOTFOUND CURSOR attribute usage.
2. There is no precise way to decide the size limit.
3 depends on number of records. If you have a lot of records always use LIMIT that improves performance.After reading the link that was posted by Blu, I am to edit this post.
1. do not use CURSOR attribute when you use collections within a cursor. Use methods of collection such as COUNT or EXIST etc.
@Blu,
Thanks much for the link.
Thank you

Procedure failed when using bulk collect clause and works with the cursor
Hi all
I use "BULK collect into" clause in my procedure and it is a failure after 21 minutes and gives the error "end of file communication channel.
After that this error comes when I tried to connect the database it gives following error.

Shyam ~.Shyam,
I agree with Billy.
Why are you not using an INSERT..SELECT ? Also, what are you trying to achieve by - incremental commits? - copying data from one table to another (using expensive I/O)? - using dynamic DML? Most of these approaches are typically wrong - and not recommended for scalable and performant Oracle applications.I could see you using a CURSOR for LOOP if you change the data inserted so that you could not encapsulate the changes in a query, but you do an insert in right in the table of your cursor. A much more effective way would be to use the following changes I made to your code sample:
PROCEDURE WORK_KIOSK_FULL(AN_JOBID IN NUMBER, AC_SQLCODE OUT VARCHAR2, AC_SQLERRM OUT VARCHAR2) IS BEGIN EXECUTE IMMEDIATE 'truncate table crstools.drt_bom_work_kiosk'; /* Note: The APPEND hint forces a Direct Path INSERT (see Link below code sample) and is combined with the NOLOGGING Hint */ /* To dramtically increase performance. The Direct Path INSERT inserts records above the High-Water Mark on the table. */ INSERT /*+ APPEND NOLOGGING */ INTO CRSTOOLS.DRT_BOM_WORK_KIOSK (JT_ID ,ACTUAL_HRS_TO_COMPLETE ,ACTUAL_HRS_TO_RESPOND ,AGENT_NAME ,ASAGENT_SOE_ID ,AP_SYSTEM -- ,ASSIGN_WORK_REQUEST_COMMENT /* I commented out this COLUMN because it doesn't make sense to me to insert */ ,BILLABLE /* a couple of space characters into a table. If the intent is to leave the column NULL */ ,BUILDING /* don't include it in your INSERT statement and it will be NULL. If there is a valid reason */ ,BUILDING_ID /* for inserting the spaces, then remove the "line comments" from the insert and select statments */ ,BUILDING_STATUS ,CAUSE_TYPE -- ,COMMENTS ,COMPLETED_BY

Here is a code to test with no logic :), when I use the LIMIT clause, he lifts a PL/SQL compilation error. To "LIMIT" the transformation into pieces collection it will be only possible by using the cursor and cursor Fetch bulk collect into a collection?
declare
type tbl_emp is table of the emp1% rowtype;
v_emprec tbl_emp;
Start
Select * block to collect in emp1 v_emprec; - limit 5000;
because me in 1.v_emprec.count
loop
Update emp1
set comm = nvl (comm, 1) * I
where empno = v_emprec (i) .empno;
dbms_output.put_line (' employee ' | v_emprec (i) .ename |) "The Commission updated"); "
end loop;
end;

Then use the appropriate syntax. Open the cursor and in bulk fetch with limit.

Why you using the collection type and perform the UPDATE? Just perform the UPDATE directly. Can be a simple MERGE statement
merge into emp t using ( select * from reg ) r on ( t.id = r.id and t.monum = r.mob and t.accnum = r.accno and t.typ = '01' and t.ttype = '82' and t.txnstatus = 'C' ) when matched then update set t.mid = r.midNote: Untested Code

Using the slider for and BULK COLLECT INTO
Hi all
in this case we prefer to use the cursor AND the cursor with the LOOSE COLLECTION? The following contains two block this same query where used FOR the slider, the other is using COLLECT LOOSE. The task that is running better given in the existing? How do we measure performance between these two?
I use the example of HR schema:
In this code, I put a timestamp in each block, but they are useless, since they both launched virtually instantaneous...declare l_start number; BEGIN l_start:= DBMS_UTILITY.get_time; dbms_lock.sleep(1); FOR employee IN (SELECT e.last_name, j.job_title FROM employees e,jobs j where e.job_id=j.job_id and e.job_id LIKE '%CLERK%' AND e.manager_id > 120 ORDER BY e.last_name) LOOP DBMS_OUTPUT.PUT_LINE ('Name = ' || employee.last_name || ', Job = ' || employee.job_title); END LOOP; DBMS_OUTPUT.put_line('total time: ' || to_char(DBMS_UTILITY.get_time - l_start) || ' hsecs'); END; / declare l_start number; type rec_type is table of varchar2(20); name_rec rec_type; job_rec rec_type; begin l_start:= DBMS_UTILITY.get_time; dbms_lock.sleep(1); SELECT e.last_name, j.job_title bulk collect into name_rec,job_rec FROM employees e,jobs j where e.job_id=j.job_id and e.job_id LIKE '%CLERK%' AND e.manager_id > 120 ORDER BY e.last_name; for j in name_rec.first..name_rec.last loop DBMS_OUTPUT.PUT_LINE ('Name = ' || name_rec(j) || ', Job = ' || job_rec(j)); END LOOP; DBMS_OUTPUT.put_line('total time: ' || to_char(DBMS_UTILITY.get_time - l_start) || ' hsecs'); end; /
Best regards
Val(1) bulk fired fresh primary use is to reduce the change of context between sql and pl sql engine.
(2), you should always use LIMIT when it comes with bulk collect, this does not increase the load on the PGA.
(3) and the ideal number of BOUNDARY lines is 100.Also if you really want to compare performance improvements between the two different approaches to sql pl try to use the package of runstats tom Kyte

Thank you very much
Hi 5181139
As Paulzip and Jarkko Turpeinen have pointed out, you could do it using only SQL...
This is a course using COLLECT in BULK:
DECLARE blimit CONSTANT PLS_INTEGER := 500; CURSOR curupdate1 IS SELECT MF_TJ.UID_LO FROM MF_TJ WHERE MF_TJ.DTYP IN (SELECT CD FROM MF_DOC_TYPE WHERE MF_DOC_TYPE.DTYP_CAT = 'xx') AND MF_TJ.LINE_TYP IS NULL; TYPE c_arr IS TABLE OF curupdate1%ROWTYPE; c_rows c_arr; BEGIN OPEN curupdate1; LOOP FETCH curupdate1 BULK COLLECT INTO c_rows LIMIT blimit; FORALL i IN c_rows.FIRST..c_rows.LAST UPDATE MF_TJ SET MF_TJ.LINE_TYP = 'NR' WHERE MF_TJ.UID_LO = c_rows(i).uid_lo; FORALL i IN c_rows.FIRST..c_rows.LAST UPDATE MF_AJ SET MF_AJ.LINE_TYP = 'NR' WHERE MF_AJ.TJ_UID_LO = c_rows(i).uid_lo; EXIT WHEN c_rows.COUNT < blimit; END LOOP; CLOSE curupdate1; END;See you soon,.

Bulk collect / forall type what collection?

SELECT h.cust_order_no AS custord, l.shipment_set AS Tess
Info.tlp_out_messaging_hdr h, info.tlp_out_messaging_lin l
WHERE h.message_id = l.message_id
AND h.contract = '12384'
AND l.shipment_set IS NOT NULL
AND h.cust_order_no IS NOT NULL
H.cust_order_no GROUP, l.shipment_setI would like to get the 2 selected fields above in a new table as quickly as possible, but I'm pretty new to Oracle and I find it hard to sort out the best way to do it. The query below is not working (no doubt there are many issues), but I hope that's sufficiently developed, shows the sort of thing, I am trying to achieve:
DECLARE

TYPE xsset IS TABLE OF THE info.tlp_out_messaging_lin.shipment_set%TYPE;
TYPE xarray IS the TABLE OF tp_a1_tab % rowtype INDEX DIRECTORY.

Short-term solution may be to a world point of view. Pay once per hour for the slow and complex query execution. Materialize the results in a table (with clues in support of queries on the materialized view).
Good solution - analysis logic and SQL, determine what he does, how he does it and then figure out how this can be improved.
Ripping separate cursors in SQL and PL/SQL code injection to stick together, are a great way to make performance even worse.
