  Hello
  
  Take the base for our Referenece emp table and allows to assume that it contains about 60000 Records and all the deptno in this table are out of 10. Please allow an update statement that would update the deptno column in the table EMP ((according to) order by EMPNO) in each increment of 1 120 reviews. (DeptNo to be incremented by 1, 10, 11, 12, etc.).
  
  First 120 deptno records should be 10,
  Then 120 deptno records should be 11 and so on.
  .
  .
  .
  .
  .
  .
  For the last 120 deptno records should be updated with 500.
  
  Please notify.
  
  Kind regards

• List of PT TABLES, which contain the digital certificate

  Team,

  We have set up free sign certicate in our environment.

  So, can someone share the list of the PT TABLES, which contain the digital certificate.

  Because, we do not have to refresh the environment and I don't want to lose the digital certificate after the update.

  Thank you

  Take a look at the following.  I did something similar in refresh scripts

  • PSCERTDB - raw certificate data
  • PSCERTDEFN - certificates
  • PSCERTDEFNDEL - certificates delete record.
  • PSCERTISSUER - the issuer of the certificate

• How to upgrade an ESXi host from the command line

  Sorry for bumping an old thread. I'm new to ESXi. I'm under ESXi 5.5 build 1331820 and I am at a loss how to apply patches.

  Preferably, I would like to apply all the relevant patches through console (SSH). Can someone give me pointers how to do this? Thank you

  Moderator note (a.p.): branched to a new discussion of software patch to version 1331820?

  Welcome to the community,

  on how to patch a ESXi host from the command line, please see for example http://kb.vmware.com/kb/2008939

  Basically download you the latest hotfix package and install it using the command esxcli . That said, please make sure that your hardware is supported by the patch that you want to apply (see http://www.vmware.com/go/hcl). You can also do before installing the patch, is to do a "dry - run" to know what . VIBS are removed and which are installed by the patch. To do this add -dry - run to the esxcli command line.

  In the case where something goes wrong, you can revert to the previous state by pressing SHIFT-R , while the ESXi hosts begins the start-up.

• What is the right way to commit 100,000 lines?

  Hi guys and girls,

  With the help of JDev 11.1.2.3.0.

  I have 10 000 ranks of the master, gave each of them runs in 9 different algorithms, 90 000 detail lines.  I now need to commit the 100,000 (10 000 masters & 90 000 retail) lines to my database.  What is the best way to accomplish this feat?  I am open to suggestions and ideas.  I'm not married to a particular approach, any strategy and have little experience running such a large DataSet.

  Currently, I iterate through the lines view object 10 000 in my application and for each line module, apply a Prediction algorithm, whose results are inserted into an object of the detail view.  The main line of vo is updated with a reference for the best results in detail, and then all have been committed through getDbTransaction.commit ();

  Is there a way to say, commit 10 000 lines, let the database do its thing and once again the calculations?  Once the database did commit, commit an another 10,000.  In this way the module of the application and the database work in parallel rather than one waiting on the other.

  Thoughts?

  Thank you

  Will be

  It looks like that there. Check the Advanced Techniques of object entity - 11 g Release 1 (11.1.1.7.0)

  As far as I know, there is no parallel work (adf and db). What you can do is to use the PL/SQL to insert the data and calculations on the side of the db. This can be faster than to browse all lines in the adf.

  Yes, I slide collections and was trying to reach somwthing on similar lines to which you provided the code example...

  My essay is equipped to take a collection: initialized with values of say 3-4...

  Take other tables... A column... and update the column in the table (not PK, FK anything) using the values of the initialized collection...

  However, I am stuck between the two on how the UPDATE clause should be...

  OK, if it's just because you want to practice with collections, you might do something like this...

  Of course, there is treatment rank by rank and is not best for performance, but it allows you to access your collection that you created names.

• How to upgrade a table after each iteration?

  Hello

  I have a vi which works fine but the problem is that it updates all the data once the vi stops running. I want something as soon as (for outside for loop) 1 iteration it performs updates the table in front of the Panel, then 2nd iteration, it updates again and so on. Can anyone help me please with this.

  Thank you

  In fact, in your case, there are a simpler way to do it... If we talk about the pink channel on the first loop indicator.

  Just move the table from outside the loop inside the loop indicator.

• How to upgrade the table based on data in multiple tables?

  TABLE1:

  If TABLE1. TXN_ID present in TABLE2, I should update the form ABC TABLE1.NAME.

  If TABLE1. TXN_ID present in table 3, I should update TABLE1.NAME as XYZ.

  I can update this by running 2 scripts.

  UPDATE TABLE1 SET B.SID = 'ABC' WHERE

  IT EXISTS (SELECT 1 FROM TABLE2 B WHERE B.TXN_ID = A.TXN_ID);

  UPDATE TABLE1 SET B.SID = "XYZ" WHERE

  IT EXISTS (SELECT 1 FROM TABLE 3 C WHERE C.TXN_ID = A.TXN_ID);

  How can we do this in a single script? I have more than 10 tables as TABLE2 and TABLE3.

  Output should be:

• How to create a table with editable column values.

  Hello world
  I think it's very simple, but I am unable to find how to do this. This is my requirement. I need to create a table with n columns and 1 line initially. the user must be able to enter data into this table and click of a button must insert the data into the database table. Also, there should be a button at the bottom of the table to add 1 line to the table.
  
  I know how to do the insertion of data, but can someone please let me know how to create a table which allows the user to enter data and how to create a line button Add 1?
  
  
  Thanks in advance!

  Raghu,

  Go through the tutorial of Toolbox Page & Advanced section of the Guide of the OFA table.

  Step 1 - you need to create EO & VO from this EO. This EO will be table of database where you want to insert the data.

  Step 2 - create an advanced table region. (See this section in table advanced for more details)

  Step 3 - attach this VO in the BC4J region advanced Table component.

  looking over the data, first recordings and the third are legitimate serial numbers (correct to the customer's specifications), second record is not legitimate because it has a dashboard as a suffix, we found there are several illegitimate serial numbers exist, must be updated with the right of the serial numbers which I analyzed in great after having pulled data from mtl_material_transactions oe_order_lines_all, mtl_serial_numbers, mtl_system_items_b
  Basically, these are all RMA
  
  I need to update the second album under the name 1094SUZ-0538JQ0003-B by the guidelines, updating, I need to keep all the existing contracts, warranty, what ever material operations, there need to be same.
  
  We have a package to update serial numbers using the IB (csi_Item_Instance_Pub.update_item_instance) API, but it updates only the records which has no current serial number of this instance, if there is a serial number already exists, it does not work.
  
  user to define the error msg ' serial number 1094SUZ-0538JQ0003-a inventory of significant transactions. " This serial number cannot be used to update an existing Instance of point", but I need to update anyway! or am I missing something here, please advice me

  This used. Is perhaps not perfect, but you should get there. Only if the table is saved (all tables seeded should be registered) it will work.

  Select a.table_name, distinct b.column_name from fnd_tables a, fnd_columns b
  where a.table_id = b.table_id
  and upper (b.column_name) like ' % SERIAL.

  Also it is a very old, but if you need history for this change adds logic to insert story as well...

• How to upgrade a selection one line of the table based on values in another table when there is exactly one matching entry and negligence if there is more than a football game

  Hello

  I'm trying to achieve the following objectives:

  1. in table A, select rows based on the values in column 2. something like SELECT * FROM TABLE A WHERE (COLUMN2 = 'X' or Column2 IS NULL)

  2 and these values selected, I want to update Column3 from Table A if TableA.column1 = TableB.column1, but only if there is exactly one game. If there are multiple matches, column 3 of the table article updated.

  That's what I've tried so far.

  UPDATE TABLE_A

  SET

  TABLE_A.COLUMN3 = (SELECT COLUMN3 OF TABLE_B

  WHERE ((TABLE_B.COLUMN1 = TABLE_A.COLUMN1) AND ( TABLE_B.COLUMN1 IN (SELECT Column1 FROM TABLE_B GROUP BY COLUMN1 , HAVING COUNT (*) = 1)))

  WHERE EXISTS (SELECT * FROM TABLE_A)

  WHERE ((TABLE_A.COLUMN2 = 'X' OU TABLE_A.COLUMN2 = 'Y') AND (TABLE_A.COLUMN4 IS NULL OR TABLE_A.COLUMN4 = ' ')));

  More details on my DB environment:

  Version Info:

  Oracle Database 11 g Enterprise Edition Release 11.2.0.4.0 - 64 bit Production

  PL/SQL Release 11.2.0.4.0 - Production

  Toad, but, depending on whether the query updated all lines. I would really appreciate if someone could tell me how to fix my request.

  Thanks in advance.

  Exists it predicate in the block of update will be set to true if there is at least one row in table_a where column2 is X or Y and column4 is null or a space. You need to correlate exists it with the outer query query (I'm guessing on column1) to get the result I think you want.  However, who would update all rows in table_a who meets the criteria, there is a corresponding row in table_b, affecting Column3 lines form null not matched or not.  (Again), I'm guessing that's not your intention.  If you only want to update the lines in table_a which have a corresponding line in table_b and meet the other predicate, then I think you want something more like:

  Update table_a

  Set table_a.column3 = (select column3 of table_b

  where table_b.column1 = table_a.column1 and

  Table_B.Column1 in (select column1 from table_b

  Group by column1, having count (*) = 1))

  where ((table_a.column2 = 'X' ou))

  table_a.Column2 = 'Y') and

  (table_a.column4 is null or)

  table_a.column4 = ' ')) and

  table_a.Column1 in (select column1 from table_b

  Group by column1, having count (*) = 1)
