• Performance issue Bulk Insert PL/SQL table type

  Hi all
  
  I put in work of a batch to fill a table with a large number of data records(>3,000,000). To reduce the execution time, I used PL/SQL tables to temporarily store data that must be written to the destination table. Once all documents are piling up in the PL/SQL table I use a FORALL operator for bulk insert the records in the physical table.
  
  Currently, I follow two approaches to implement the process described above. (Please see the code segments below). I need to choose how to best wise performance between these two approaches. I really appreciate all the comments of experts about the runtime of the two approaches.
  
  (I don't see much difference in consumption of time in my test environment that has limited the data series. This process involves building a complex set of structures of large product once deployed in the production environment).
  
  
  Approach I:_
  DECLARE
  TYPE of test_type IS test_tab % ROWTYPE directory INDEX TABLE;
  test_type_ test_type.
  ins_idx_ NUMBER;
  BEGIN
  ins_idx_: = 1;
  NESTED LOOPS
  test_type_ (ins_idx_) .column1: = value1;
  test_type_ (ins_idx_) .column2: = value2;
  test_type_ (ins_idx_) .column3: = value3;
  ins_idx_: = ins_idx_ + 1;
  END LOOP;
  
  I_ FORALL in 1.test_type_. COUNTY
  INSERT INTO test_tab VALUES (i_) test_type_;
  END;
  /
  
  
  Approach II:_
  DECLARE
  Column1 IS a TABLE OF TYPE test_tab.column1%TYPE INDEX DIRECTORY.
  Column2 IS a TABLE OF TYPE test_tab.column2%TYPE INDEX DIRECTORY.
  Column3 IS a TABLE OF TYPE test_tab.column3%TYPE INDEX DIRECTORY.
  column1 column1_;
  column2_ Column2;
  column3_ Column3;
  ins_idx_ NUMBER;
  BEGIN
  ins_idx_: = 1;
  NESTED LOOPS
  column1_ (ins_idx_): = value1;
  column2_ (ins_idx_): = value2;
  column3_ (ins_idx_): = value3;
  ins_idx_: = ins_idx_ + 1;
  END LOOP;
  
  FORALL idx_ in 1.column1_. COUNTY
  INSERT
  IN n_part_cost_bucket_tab)
  Column1,
  Column2,
  Column3)
  VALUES)
  column1_ (idx_),
  column2_ (idx_),
  column3_ (idx_));
  END;

  Performance is more than just reducing the execution time.

  Just as smashing a car stops more than a car in the fastest possible time.

  If it was (breaking a car stopping all simply), then a brick with reinforced concrete wall construction, would have been the perfect way to stop all types of all sorts of speed motor vehicles.

  Only problem (well more than one actually) is that stop a vehicle in this way is bad for the car, the engine, the driver, passengers and any other content inside.

  And pushing 3 million records in a PL/SQL 'table' (btw, that is a WRONG terminology - there no PL/SQL table structure) in order to run a SQL cursor INSERT 3 million times, to reduce the execution times, is no different than using a brick wall to stop a car.

  Both approaches are pretty well imperfect. Both places an unreasonable demand on the memory of the PGA. Both are still row-by-row (aka slow-by-slow) treatment.

• How to find lines that are inserted in the last minutes n?

  Hi all
  I have a log table where, whenever a warning is issued, a new row is added. The table contains a field with the sysdate when the warning was issued.
  I would need to collect all the warnings in the last 30 minutes (supposed) and send a mail to the administrator. Looking at some FAQ I have explained this:
  
  Select * from PROCEDURE_LOGS p where ((p.DATE_LOG-sysdate) *-1440) < 30
  
  However, it does not do anything.
  Can someone help me correct this statement?
  Thank you very much
  Frank

  Assuming that the field is a DATE field and time information are included in this field to date. Then your application should work.

  I would write it differently, but the logic is the same.

  select *
  from procedure_logs p
  where (sysdate - p.date_log) * 24 * 60 <= 30
  ;
  

  Perhaps the information is not yet committed, so that you don't see it in your additional session?

  Look at your data and consider wheather this record must be included or not.

• Bulk insert in an external table

  Hi, I get the error ora-29913, ora-01410 trying to do a bulk insert of external table

  INSERT

  IN CORE_TB_LOG

  (SELECT 'MODEL', 'ARCH_BH_MODEL', ROWID, "MODEL-D-000000001', - 45, 'A', SYSDATE, 'R'")

  OF ARCH_BH_MODEL1

  ERROR on line 1:

  ORA-29913: error in executing ODCIEXTTABLEFETCH legend

  ORA-01410: invalid ROWID

  ARCH_BH_MODEL1 is the external table.

  
  

  What's wrong?

  
  

  Thank you.
  

  Hello

  There is no ROWID in external tables.

  It makes sense: ROWID identifies where a line is stored in the database; It shows the data file and the block number in this file.

  External tables are not stored in the database.  They exist independently of any data file in the database.  The concept of an Oracle block does not apply to them.

  Why would you copy the ROWID, even if you could?

  Apart from ROWID and SYSDATE, you select only literals.  You don't want to select all the real data of the external table?

  What is the big picture here?  Post a small example of data (a CREATE TABLE statement and a small data file for the external table) and the desired results from these sample data (in other words, what core_tb_log must contain after INSERTION is complete.)  Explain how you get these results from data provided.

• Bulk insert table

  Hello
  Version 10g
  
  I need to get an array of 100 recordings in pl/sql procedure.
  The table is built on columns.
  Then I need bulk insert into the table.
  
  Question: Is it possible to get a table in the stored procedure?
  
  Thank you

  Yes you can get it. Check the code below.

  SQL> create type trec is object (a number, b number);
    2  /
  
  Type created.
  
  SQL> create type tlist is table of trec;
    2  /
  
  Type created.
  
  SQL> create table coltab(col1 number, col2 number, entry_date date);
  
  Table created.
  
  SQL> ed
  Wrote file afiedt.buf
  
    1  create or replace procedure arraytest (p tlist) is
    2  begin
    3  for i in p.first..p.last
    4  loop
    5  insert into coltab values
    6  (p(i).a,p(i).b,sysdate);
    7  end loop;
    8* end;
  SQL> /
  
  Procedure created.
  
  -----------Testing--------------------
  SQL> declare
    2  l tlist := tlist(trec(1,2),trec(4,3));
    3  begin
    4  arraytest(l);
    5  end;
    6  /
  
  PL/SQL procedure successfully completed.
  
  SQL>
  SQL>
  SQL> select * from coltab;
  
        COL1       COL2 ENTRY_DAT
  ---------- ---------- ---------
           1          2 04-AUG-10
           4          3 04-AUG-10
  

  If you do not use the concept of line, try this. This works in a similar way.

   create or replace procedure arraytest (p tlist) is
   begin
   insert into coltab
   select t1.*, sysdate from table(p) t1;
  end;

• OracleCommand - insertion of configurable tables memory leak...

  Hello
  
  I have a .net application batch bulk inserts into a table using parameterized paintings sent to a stored proc.
  
  The pseudo-device application looks like this:
  
  For each report
  -Recover 14 K of data lines
  
  -create tables based on data
  
  -specify link count
  
  -connect
  
  -OracleCommand.ExecuteNonQuery <-this IS WHERE MEMORY JUMPS AND NEVER CAME OUT
  
  -Connection.Close)
  
  -Connection.Dispose)
  
  -OracleCommand.Dispose)
  
  Next report
  
  
  
  At this point I'm very nearly causing a System.OutOfMemoryException exception
  
  If I add more aspects to the process that I don't know that it will happen.
  
  
  IS THERE A WAY TO RECOVER THIS MEMORY OTHER THAN THE WAY I DO? I TRIED SEVERAL WAYS (using OracleCommand..., OracleCommand = null, OracleCommand.dispose) BUT IT's NOT FACT NO DIFFERENCE.
  
  
  
  Thank you

  Hello

  PACO is the version of the specific customer. 11g odp requires client 11g, 10g OPD requires 10g client etc. I'm surprised your app works even based on what you said (check the forums initializer Exception Type, you'll see a mess of positions).

  In any case, the answer is, you need to install a new Oracle and ODP client to use the new ODP. There is also a bundle of xcopy from 11 g that makes it a little less painless.

  It will be useful,
  Greg

• Bulk Insert for 10 million records - error - Snap shot too old

  Hello
  
  I try to use 'Bulk Insert' for the insertion of 10 million documents. This piece of code is placed in the procedure. For my bad, I have found often the procedure (managed by a batch process) becomes the question of "Snapshot too old" error-ed
  Through a few blogs made me feel this cold size Undo retention aid increase.
  My question is: fact between it "COMMIT" contributes to the error. The value of the validation between the Bulk Insert is 100,000.
  
  Thanks in advance!

• Single line vertical when using the ADF to Scan or copy on HP Officejet Pro 8600

  Printer HP Officejet Pro 8600 Premium (CN577A)

  OS: MS 7 64-bit

  When you use the ADF for my printer HP CN577A Officejet Pro 8600 Premium, I get a single vertical line on the document which is produced. This occurs when copying or scanning, both black and white and in color. If I scan or copy using the glass, I do not get the vertical line.

  I already tried troubleshooting.  I unplugged the printer, left without electricity for several minutes; that didn't fix the problem.  Then, I cleaned the rollers and glass; I always get the vertical line, but only when using the ADF.

  My firmware version is up to date (CLP1CN1150CR).

  What should I check next?

  The only difference between the ADF and scanning flat, from a point of view of the scanner is there on the glass, it happens.  I suggest you get a bright flashlight and examine the corresponsing area hence is the line, it's almost certainly a spot on the strip of thin glass which is being just in the right place.

  I've seen some people suggest that put a flashlight almost parallel to the Strip, it shines from the bottom can highlight the area problem.

• HP 8500 has showing vertical red lines on all the documentation scanned with the ADF

  I had scanned a doc with red ink which I guess was still a little damp.  I have cleaned the rollers, but still get a few red vertical lines on copies scanned on the ADF.  Help please.

  Hello

  Some of the red ink may have been transferred to the scannerglas in the ADF, so clean it only to.

• I'm getting a vertical line in the middle of the page when I use the ADF on my Officejet Pro 8500 a but

  HP Officejet Pro 8500

  Windows XP

  No error message

  No changes to the system

  Scan using the ADF puts a vertical line in the middle of the scanned page.  This does not happen when I scan from the flat screen

  Brian, this is going to be a pretty easy fix. What you're going to need to get is a lint cloth (as a microfibre cloth or a filter coffee) and get just a wet touch. Then, open the top of your printer to reveal the glass. There are two sections, one large, and that is a thin strip of glass on the left side. If the line makes its appearance in the ADF scans/copies only - clean this thin section with a moist, lint cloth.

  This should help you!

  Let me know and have a great day!

• LJ Pro M1536 vertical line on copies of the ADF

  I have a (JSF) page that has table. My requirement is I need make the line as read only with the exception of the newline (created with the new button) as update / insert able. Please suggest a way around so that the user can only add records to the table but couldn't change all existing records in the table.
  
  Please advice.

  If you are using ADF business components, just go to the VO on which is based the table and brand every attribute as "Editable when new" only.

• How to jump a line to insert in the staging table

  Hello world
  
  I'm actually transform data from a source table in the staging table and staged, and then at the final table. I generated a primary key using the sequence. As I put the insert method of the staging table as truncate/insert. So whenever the mapping is loaded, intermediate table is truncated and new data are inserted but as I am with sequence of intermediate table, it will give the new numbering of old data from the source table and it will be duplicated data in the target table. So for this reason I use key look up on top of some attributes of entry and that the use of expression that I try to avoid duplication. At each exit of the attributes in the expression, I'm trying the case statement
  
  "BOLD" CASE WHEN INGRP1. ROW_ID IS NULL
  THEN
  INGRP1.ID
  END * bold *.
  
  Because of this condition, I get the error message
  
  "BOLD"
  Warning
  ORA-01400: cannot insert NULL into ('SCOTT'. "" "" STG_TARGET_TABLE '. "" ROW_ID")
  "BOLD"
  
  But I'm stuck when the row_id value is zero, that that condition or statement should I write to jump the insertion of data. I want to insert data only when ROW_ID IS NULL.
  
  
  
  
  Kindly help me.
  
  Thank you
  
  Concerning
  Suhail Dayer

  You do not need identical tables to use LESS, only the 'select list' must match. Assuming you have the key of the enterprise (one or more columns that uniquely identifies a row of your data source) in the source and the final table, you can do the following:

  -Use a Set operation where the result is the key to the business of staging table LESS the key to the business of the final table
  -The output of the set operation is then joined to the staging table to get the rest of the attributes for these lines
  -The output of the join is inserted into the final table

  This will ensure that the lines with the new keys to the company are responsible.

  Hope this helps,
  Roald
