• delete all the records in a table, the speed of insertion is not change.

  I have an empty table, and I insert a record need 100ms.
  During this table a 40,0000 trace, I insert a record need 1 s, it's ok, because I need to make a comparison according to an index before inserting a record need, so more record, more time.
  The problem is when I delete all the record in this table, the insertion time is always 1s, not reduce to 100ms. Why?

  Hello

  Read this part of the oracle documentation

  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14220/logical.htm#CNCPT004

  The reason is always 1s, because when you inserted 400ko record as HWM (high tide is the border between old and new space in a segment.) moved to the top. And when you remove all records of your HWM still in the same coordinate system and that you have not reset to 0. So when you insert 1 it save free space and after finding faces (usually a regular insertions got 6 steps it inserts data). If you truncate your table you and try it again it will be faster that your HWM is reset to 0.

• How to upgrade all the record for a particular column in a table based on search criteria.

  Hi all

  I'm new to ADF. I have a requirement where I have to perform the update of mass on a table.

  Scenario:

  Ex: I have a search region manual dept. where I search with deptId: 20. I get 20 records in my table. now I have another area where I have an inputchoice list that contains all the column names that exist in the dept table. Beside that, I have a text box and a button update

  The user now, first research with dept id: 20 and click on the button Search, where it shows 20 record in the table. He then select an input choicelist(ex: ManagerId) column, then enter the new value in the decision-making box(ex: abc) then click on the button update.

  Now, I want to, all the records in the ManagerId column with dept id: 20 update with the new value 'abc '.

  Can someone help me with the code.

  Thanks in advance...

  Hello

  If you go to your VO and generate the ViewObjectImpl, here you can create a method that contains two parameters, 1 the name attribute and 2 the value.

  Then you can follow something as explained in this post:

  ADF tutorial: how to apply actions in bulk to a view object lines

  The only difference is that you must create a method like this:

  ' Public Sub updateAttribute (attribute String, Integer value) {}

  RowSetIterator iter = createRowSetIterator (null);

  While (iter.hasNext ()) {}

  Line = iter.next ();

  row.setAttribute (attribute, value);

  }

  }

  Then execute you who expose a customer interface and then after you filter your table according to your criteria just this method passing the correct parameters.

  Concerning

• Changing all the semantic VARCHAR2 length in BYTE to CHAR columns

  Hello

  our database is to use character set AL32UTF8, i.e. multibyte.

  All our VARCHAR2 columns have been specified as VARCHAR (xxx) semantic unspecified length explicit, which makes VARCHAR(xxx BYTE) because NLS_LENGTH_SEMANTICS is set on 'BYTE' (default Oracle).

  I wonder now if it would cause problems to enter and execute the ALTER TABLE statement to change all the columns of VARCHAR2(xxx BYTE) to VARCHAR2(xxx CHAR), leaving the same xxx. For example, if a VARCHAR2 column (100 BYTE) would be amended to be VARCHAR2(100 CHAR).

  If I am not entirely mistaken, - on the contrary - it would make the columns longer, not shorter; I expect to not get errors on the values of existing records being too long to change the specifications of the column in this way (as it may happen when the shortening of a VARCHAR column, for example, of varchar (10) to varchar (5)). So I think the ALTER TABLE statements should go without problem.

  I would also change NLS_LENGTH_SEMANTICS to TANK.

  Are there problems or consequences I might meet when I do this? I'm not worried about the implications for code enforcement external or such, but simply the integrity / performance / etc on the database level.

  It is a 11.2.0.x of Oracle database.

  Thank you

  You can make this change to your drawings, but not for Oracle schemas or third party. It would usually not be supported.

  You will not get the errors associated with the data in the table. However, you can encounter errors due to:

  1 index of issues of key length - the maximum length of an index key in bytes (based on the column definitions, no real content column) is limited to about 70% of the size of the block of the tablespace containing the index. If you try to do a column belonging to a larger index key by applying the semantics of length in characters, you get an error if the change causes the index key limit.

  2. some columns cannot be changed. This includes, but may not be limited to, the columns that are referenced by expressions of virtual column and the functional index expressions, columns that have indexes defined on them, and columns field belonging to a partitioning key.

  3. you can not change the columns that store attributes of the type defined by the user in this way. You must change the definition of type instead.

  Also, do not change NLS_LENGTH_SEMANTICS initialization file. Include the keyword CHAR in your scripts or ALTER SESSION SET NLS_LENGTH_SEMANTICS = CHAR in these scripts. Value of the initialization file will affect all the scripts for Oracle products and third-party and can create tables with the semantics of unexpected length. Therefore, for compatibility reasons, this parameter in init.ora/spfile parameters is not recommended.

  If I understand correctly you need to change all your aps by changing the models?

  The fastest way is to change the actual models source if you have permission to do so.

  the table I fold models is wwv_flow_templates

  Uninstall the toolbar Ask and it should work again. There is a compatibility issue with the Ask and Firefox toolbar that prevents the opening of new tabs.

  There are a few places to check for the Ask toolbar:

  Hello mattyboy1212,

  Try these steps and see if you can associate the default programs. If they are associated with Word, and then change them to the correct program.

  1. click Start and then click Control Panel.

  2. click on programs link.

  Note: If you see small icons or large icons in the control panel display, you will not see this link. Click on the default programs icon, and then click the link associated with a file type or Protocol with a program . Go to step 4.

  3. click on the link to Open a file in a specific program type always under default programs .

  4. in the set Associations window, scroll down until you see the file extension that you want to change the default for program.

  5. click on the extension of the file to select it, once you have found what you are looking for.

  6. click the button of change... program above the scroll bar.

  The Open with dialog box should appear.

  7. look into options for programs recommended and choose the application you want to open it with the file extension when you double-click on the particular type of the file on your computer.

  8. click OK in the Open with window. Windows 7 is going to update the list of file associations to display the new default program to open this type of file.

  9. click the button close the bottom together associations . You can also close the window of the Control Panel if it is still open.

  10. at this stage, when you double-click on any file with this particular file extension, the program you partner in step 7 will launch and load the particular file.

  The left pane is a "choose one". "All photos" are just that. 'G' is a different option.

  Lightroom is not a file Explorer. He knows only the drives and files that you have imported the photos of. If LR shows not all of the photos that are on your hard drive, it is because you did not import all photos.

  If LR shows you a photo in "all photos" but do not show it in the folder you think he is in, go to "all photos", select the image, right click "view in the library folder. This will show you where LR think the picture is.
