bulk collect with limit
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?

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?

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.

Bulk collect with sequence Nextval
Hello
Oracle Database 10 g Enterprise Edition Release 10.2.0.4.0 - 64 bit
Had a doubt about the collection in bulk with nextval sequence. You need to update a table with a sequence of Nextval.
where should I place select below in the proc is this before or after the loop
< font color = "red" > SELECT prop_id_s.nextval INTO v_prop_id FROM dual; < / make >
Published by: 960736 on January 23, 2013 12:51CREATE OR REPLACE PROCEDURE (state IN varchar2) AS CURSOR get_all IS SELECT /*+ parallel (A, 8) */ A .ROWID from Loads A WHERE A.Prop_id IS NULL; TYPE b_ROWID IS TABLE OF ROWID INDEX BY BINARY_INTEGER; lns_rowid b_ROWID; BEGIN OPEN Get_all; LOOP FETCH get_all BULK COLLECT INTO lns_rowid LIMIT 10000; FORALL I IN 1 .. lns_rowid.COUNT UPDATE loads a SET a.prop_id= v_prop_id (I) WHERE A.ROWID = lns_rowid (I) AND a.prop_id IS NULL; COMMIT; EXIT WHEN get_all%NOTFOUND; END LOOP; CLOSE Get_all; END; /Hello
It depends on what results you want. All updated rows would take the same value, or should all get unique values?
Whatever it is, you don't need the sliders and loop. Just a simple UPDATE statement.
If each line requires a unique value of the sequence, then
UPDATE loads SET prop_id = prod_id_s.NEXTVAL WHERE prop_id IS NULL ;If all the lines that have a need to the same value null, then:
SELECT prod_id_s.nextval INTO v_prop_id FROM dual; UPDATE loads SET prop_id = v_prop_id WHERE prop_id IS NULL ;Don't forget to declare v_prop_id as a NUMBER.
I hope that answers your question.
If not, post a small example of data (instructions CREATE and INSERT, only relevant columns) for all the tables and the involved sequences and also publish outcomes from these data.
If you ask on a DML statement, such as UPDATE, the sample data will be the content of the or the tables before the DML, and the results will be the State of the or the tables changed when it's all over.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).

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); END; -
In BULK COLLECT with loop for?
Let's say I have a table with a column number and a date column.
I also have a query using a number and a date as a parameter. I want to run this query for each row in the table (using the column date and number of lines as parameters). If my thinking is looping through the rows and the query parameters for each line. It becomes a large number of queries select. Is it possible to use bulk collect here? All the examples I've seen where he uses a predefined cursor. Also, I don't know how to fix this problem without a cursor.
Here's the query I want to do for each line:
select * from reading_values rv, (select * from (select id, datereading from readings, where datereading < p_date and pointid = p_id order by datereading desc) where rownum <= 1) t where rv.reading_id = t.idAfter reading your initial statement 3 times I simply add a third table to select it. I call this tableX colb and two columns cola (number) (date).
select rv.*, r.*, row_number() over (partition by r.pointid order by r.datereading desc) rn from reading_values rv join readings r on rv.reading_id = r.id join tableX x on x.colA = r.pointid and r.datereading < x.colB order by r.pointid, datereading descYou can restrict which to return only one row for each data point by using the column rn I already added.

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
IN l_memory
SYS.v_$ session se, SYS.v_$ sesstat st, SYS.v_$ statname nm
WHERE se.audsid = USERENV ('SESSIONID')
AND st.statistic # nm.statistic = #.
AND themselves. SID = st. SID
AND nm.NAME = 'pga session in memory. "
Dbms_output.put_line (CASE
WHEN context_in IS NULL
THEN NULL
ELSE context_in | ' - '
END
|| 'Used in the session PGA memory ='
|| To_char (l_memory)
);
END show_pga_memory;

Bulk collect and type returns nothing
Hello
I have the following code:
This code returns PL/SQL procedure successfully completed.declare type view_my_type is table of admuser.my_view%rowtype index by pls_integer; --x admuser.my_view%rowtype; my_array view_my_type; cursor c1 is select * from admuser.my_view; s long; i number := 1; begin s := 'crate table '; open c1; loop fetch c1 bulk collect into my_array limit 1; --s := s ||' decode (tf.fin_dates_id, '||my_array(i).fin_dates_id||', sum(tf.act_work_cost), 0) '; s := my_array(i).fin_dates_id; exit when c1%notfound; end loop; close c1; dbms_output.put_line(s); exception when others then null; end;
but don't show me is not the variable "s".
Can you help me with this?
Thank youThere a quite a number of things not just here.
First of all, allow me to reproduce your situation:SQL> create table my_view 2 as 3 select 'hello' fin_dates_id from dual 4 / Table created. SQL> declare 2 type view_my_type is table of my_view%rowtype index by pls_integer; 3 my_array view_my_type; 4 cursor c1 is 5 select * 6 from my_view; 7 s long; 8 i number := 1; 9 begin 10 s := 'crate table '; 11 open c1; 12 loop 13 fetch c1 bulk collect into my_array limit 1; 14 s := my_array(i).fin_dates_id; 15 exit when c1%notfound; 16 end loop; 17 close c1; 18 dbms_output.put_line(s); 19 exception 20 when others then 21 null; 22 end; 23 / PL/SQL procedure successfully completed.And I SERVEROUTPUT on. Your exception handler is notoriously wrong. It is said: If something goes wrong, we'll pretend it didn't happen. And that's exactly what happened here: something has gone wrong and you have chosen to not know about it.
We will remove the exception handler to see what went wrong:
SQL> declare 2 type view_my_type is table of my_view%rowtype index by pls_integer; 3 my_array view_my_type; 4 cursor c1 is 5 select * 6 from my_view; 7 s long; 8 i number := 1; 9 begin 10 s := 'crate table '; 11 open c1; 12 loop 13 fetch c1 bulk collect into my_array limit 1; 14 s := my_array(i).fin_dates_id; 15 exit when c1%notfound; 16 end loop; 17 close c1; 18 dbms_output.put_line(s); 19 end; 20 / declare * ERROR at line 1: ORA-01403: no data found ORA-06512: at line 14A no-data-found, because you are referencing my_array (i), when I is null. Just move the OUTPUT when a line upwards as well as your code runs better:
SQL> declare 2 type view_my_type is table of my_view%rowtype index by pls_integer; 3 my_array view_my_type; 4 cursor c1 is 5 select * 6 from my_view; 7 s long; 8 i number := 1; 9 begin 10 s := 'crate table '; 11 open c1; 12 loop 13 fetch c1 bulk collect into my_array limit 1; 14 exit when c1%notfound; 15 s := my_array(i).fin_dates_id; 16 end loop; 17 close c1; 18 dbms_output.put_line(s); 19 end; 20 / hello PL/SQL procedure successfully completed.Then next to fix things are:
-do not use the long data type Use a VARCHAR2 or a CLOB.
-' Cashier' should probably be 'create '.
-in bulk, treatment with limit 1. Now you have the worst of both sides: line by line, treatment and slightly more complex syntax
-Variable increment I
-Easier (and thus better) use a loop FORI hope this helps.
Kind regards

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

Bulk collect into a Table nested with Extend
Hi all
I want to get all the columns of the table emp and dept. So I use bulk collect into the concept of nested table.
*) I wrote the function in three different ways. EX: 1 and 2 (DM_NESTTAB_BULKCOLLECT_1 & DM_NESTTAB_BULKCOLLECT_2) does not give the desired result.
*) It only gives the columns of the EMP table. That means it takes DEPT & columns of the EMP table, but it only gives columns of table EMP.
) I think, there is something problem with nested table Extend.
) I want to know infested.
Can we use bulk collect into a table nested with extend?
If it is yes then fix the below codes (EX: 1 & EX: 2) and can you explain me please?

HII All,
I am facing a problem with in bulk collect unable to identify where my code is wrong. When I try to run the code below its getting hanged and thus leading to the end of the session. Please help me.
Here I am providing examples of data.
And my block of pl sqlCREATE TABLE R_DUMMY (FA_FAC_OS NUMBER(34,14), FAC_ID VARCHAR2(10) NOT NULL, SYSTEM_ID NUMBER(6,0) NOT NULL, WRKNG_CPY VARCHAR2(1) NOT NULL, CA_ID VARCHAR2(16) NOT NULL, FA_PRNT_FAC_ID VARCHAR2(10) ); insert into r_dummy (FA_FAC_OS, FAC_ID, SYSTEM_ID, WRKNG_CPY, CA_ID, FA_PRNT_FAC_ID) values (10000.00000000000000, 'FA000001', 1, 'C', 'CA2001/11/0002', ''); insert into r_dummy (FA_FAC_OS, FAC_ID, SYSTEM_ID, WRKNG_CPY, CA_ID, FA_PRNT_FAC_ID) values (500.00000000000000, 'FA000005', 1, 'C', 'CA2001/11/0002', ''); insert into r_dummy (FA_FAC_OS, FAC_ID, SYSTEM_ID, WRKNG_CPY, CA_ID, FA_PRNT_FAC_ID) values (-500.00000000000000, 'FA000008', 1, 'C', 'CA2001/11/0002', ''); insert into r_dummy (FA_FAC_OS, FAC_ID, SYSTEM_ID, WRKNG_CPY, CA_ID, FA_PRNT_FAC_ID) values (600.00000000000000, 'FA000013', 1, 'C', 'CA2001/11/0002', ''); insert into r_dummy (FA_FAC_OS, FAC_ID, SYSTEM_ID, WRKNG_CPY, CA_ID, FA_PRNT_FAC_ID) values (600.00000000000000, 'FA000018', 1, 'C', 'CA2001/11/0002', ''); insert into r_dummy (FA_FAC_OS, FAC_ID, SYSTEM_ID, WRKNG_CPY, CA_ID, FA_PRNT_FAC_ID) values (700.00000000000000, 'FA000020', 1, 'C', 'CA2001/11/0002', ''); insert into r_dummy (FA_FAC_OS, FAC_ID, SYSTEM_ID, WRKNG_CPY, CA_ID, FA_PRNT_FAC_ID) values (1200.00000000000000, 'FA000022', 1, 'C', 'CA2001/11/0002', ''); CREATE TABLE R_DUMMY_1 (FA_FAC_OS NUMBER(34,14), FAC_ID VARCHAR2(10) NOT NULL, SYSTEM_ID NUMBER(6,0) NOT NULL, VER_NUM NUMBER(4,2) NOT NULL ); insert into r_dummy_1 (FA_FAC_OS, FAC_ID, SYSTEM_ID, VER_NUM) values (10000.00000000000000, 'FA000001', 1, 3.00); insert into r_dummy_1 (FA_FAC_OS, FAC_ID, SYSTEM_ID, VER_NUM) values (10000.00000000000000, 'FA000001', 1, 2.00); insert into r_dummy_1 (FA_FAC_OS, FAC_ID, SYSTEM_ID, VER_NUM) values (10000.00000000000000, 'FA000001', 1, 1.00); insert into r_dummy_1 (FA_FAC_OS, FAC_ID, SYSTEM_ID, VER_NUM) values (500.00000000000000, 'FA000005', 1, 3.00); insert into r_dummy_1 (FA_FAC_OS, FAC_ID, SYSTEM_ID, VER_NUM) values (500.00000000000000, 'FA000005', 1, 2.00); insert into r_dummy_1 (FA_FAC_OS, FAC_ID, SYSTEM_ID, VER_NUM) values (500.00000000000000, 'FA000005', 1, 1.00); insert into r_dummy_1 (FA_FAC_OS, FAC_ID, SYSTEM_ID, VER_NUM) values (-500.00000000000000, 'FA000008', 1, 3.00); insert into r_dummy_1 (FA_FAC_OS, FAC_ID, SYSTEM_ID, VER_NUM) values (-500.00000000000000, 'FA000008', 1, 2.00);
