Table contains 10k records,we are going to insert data into another table with FORALL bulk collect limit 1000. if i use 10000 ,it's completed fast compared to 1000 limit.Can u tell me which one is better Limit.
View 4 RepliesI have an app that reads records from a driver table in order to update another (account) table. The idea is that it runs quickly but does not impact other processes on the system. In total I have around 1M records to update.
Originally I wanted to BULK COLLECT and employ a LIMIT of 1000 with a FORALL. The problem with this approach though is that I make two updates. One to the target table but I also need to update the driver table showing that I have processed the record. Therefore I cannot use this option to commit every time I reach the LIMIT by having a COMMIT inside the LOOP.
So instead I I have a FOR LOOP and test the count, if it is 1000 then I want to commit. I thought this syntax would be fine but I get the 'Fetch Out of Sequence' error. Below is a copy of the code.. Is this being caused by the double update... as the format of the code looks correct to me (though it is late!!)?
PROCEDURE update_set IS
CURSOR cur_get_recs IS
SELECT account_num,
ttw_active_flag,
acct_rowid,
rowid driver_rowid
FROM driver_table
FOR UPDATE OF processed;

I am trying to update a table column values if any change occurs using bulk collect and for all update not able to get idea. below is the proc working out.it is for insert and update using the cursors.

V_PARAM T_TEST_TAB;
V_STATUS NUMBER;

The procedure uses bulk collect to fetch from a normal cursor, Then I am using for all to insert into target table, The number of rows are 234965470
Question: What should ideally be the limit for my bulk collect ?
According to below, it should be in hundreds[URL]...
I put a bulk collect limit of 50000 - took close to 2 hours then i tried 10000 - just 3 mins shorter than the above time But if you commit every 500 rows, Then is there not another theory that frequent commits is not good ?
Is there something I have to ask the DBAS ?
Using the Bulk collect for insert into table,it's raising the below error.
ORA-00600: internal error code, arguments: [25027], [130], [1], [], [], [], [], [], [], [], [], []
I used bulk collect and for all statements to select and insert the data in temp table.The select SQl is returning one row. But its not inserting this row into temp table.Its not throwing any exceptions. Used ref cursor because the select statement is going for every cursor.
here modified the code and provided only one cursor.

I am processing 1 lakh rows.tell me the reason why bulk collect is taking more time. ? According to my knowledge it should take less time. do i need to check any parameter?
optimize this code. Scenario have to update about 40 million rows to static value, I'm committing 1Million rows in one loop. The first 1 millions rows are getting updated very fast probably in a 2 minute, after that the code just hungs and i don't see increase in committed rows.

I have a table emp as mentioned below:
SELECT * FROM EMP_TEST;
EMP_TEST
-----------------------------------------------------
ENO EFIRSTNAME ESECONDNAME DEPTNO
1 JOHN PAI 10
2 ABC DEF 20
3 EFG GHI 30
Now the primary key in this above table is pk_emp_test_eno on eno.
I have a requirement where i need to dump some dummy data (600000000 numbers of data ) into the emp_test based on these existing data without disabling the constraints (maintaining unique constraint for each record). And while inserting i want to commit after every 1000 insertion.
in bulk inserting dummy datas into the table as it is taking much more time to insert into the same.
1. how can i impose a restriction on a table so that the data gets updated only specific period of time say 9 a.m. to 10 p.m.
2. Can i use bulk collect in dynamic sql? If yes how?
We want to send the following XML message as IN parameter to the procedure

I need a procedure to get the records from the table for every SKU of XML message from the table and take one record for each SKU based on order precedence.And send the set of output records to the .net code. The order precedence is
If MODEL is not null that record should be high precedence and consider max lead_time
If MODEL and VK_UNIT is NULL then the precedence goes to STATE_ID.
The parameters in the procedure are
CREATE OR REPLACE PROCEDURE sku_proc
(
p_bu_id IN number,
p_model IN varchar2,
p_vk_unit IN XMLTYPE,
p_country_id IN varchar2,
[code].......
Query to get the data from the table based on the parameters.
SELECT bu_id,
model,
vk_unit,
country_id,
state_id,
Lead_Time,
[code].......
Here every SKU from XML message should be passed as p_vk_unit to VK_UNIT column in the query
210-39348
210-39348
210-39348
405-12132
340-30904
340-30904
340-30904
403-10890
403-10890
709-10007
Based on the above query assume we got the following records.
BU_ID MODEL VK_UNIT COUNTRY_ID STATE_ID LEAD_TIME FC
0 M123 210-39348 AB 0 20 A
0 M123 210-39348 AB 0 30 B
0 NULL 210-39348 AB 0 10 C
0 M123 405-12132 AB 0 10 A
0 NULL 340-30904 AB 0 30 C
0 M123 340-30904 AB 0 20 B
0 M123 340-30904 AB 0 10 A
0 NULL 403-10890 AB 0 10 B
0 M123 403-10890 AB 0 20 A
0 M123 709-10007 AB 0 10 B
0 NULL NULL AB 0 20 B
0 NULL NULL AB 1 30 A
Th final query has to return the following result to the OUT parameters p_Lead_Time p_FC of the procedure.
LEAD_TIME FC
30 B
10 A
20 B
20 A
10 B

I have external file like (.csv or .txt) which contain million of record...i wnat to upload it in backend by using form 6i/10g.
by using package text_io.fopen i read it and by using for..loop conventional method insert record into table...but it will take time..
Is there any way like we use bulk collect and FORALL in backend for inserting data into table..
Is there any way to read external file at a time and insert it ...so minimize inserting time....process will become fast.
using FORALL for inserting data into table.
Below pl/sql works fine when we write all the cursor data together:
DECLARE
TYPE t_rec IS TABLE OF T%ROWTYPE;
l_tab t_rec;
CURSOR cur IS SELECT a,b FROM t;
BEGIN
[Code]...
but I want to insert including some constant value while inserting the data like
DECLARE
TYPE t_rec IS TABLE OF T%ROWTYPE;
l_tab t_rec;
CURSOR cur IS SELECT a,b FROM t;
BEGIN
[Code]...
How to do this by using forall, or how to do without hiting performance ( more than 5000 rows i have to write.

I'm able to run the program successfully using FOR LOOP instead of BULK COLLECT but wish to run using bulk collect.
Okay I am not asking for detailed solution here but I have quick query.
One of the procedure have this cursor query returning say 10 columns and have declared an collection of that cursor type.
Now the cursor is bulk fetched in the collection.
By any means it is possible to happen that bulk collection will scramble column values ?
The cursor seem to return expected output. But when table insert happens using the collection there I see values are mismatched.
I was wondering if bulk collect can be an issue ?
How to resolve this issue?
