    The best way is not for everyone. Clear the caches unnecessarily makes your computer run more slowly while they are rebuilt. Did you have a specific problem that you thought that clearing cache can solve? If so, post on the real problem.

  • What is the best way to refresh the table after autosubmit (10.1.3.4)

    What is the best way to refresh the table after autosubmit?

    I have a page that contains a table where if one of the fields is changed it autosubmitted where the view object changes some attributes, based on the field having been changed. I need these modified attributes that appear in the table. But without doing anything, the only way to see these values is to cause the iterator updated table.

    I've been refreshing the table is having a method in a grain of beacking called "getSystemSettingIter.getCurrentRow ();". This seems to be a bit of a hack for me and I was wondering if there is a better way to get the table to update.

    Thanks in advance!

    Have you tried setting between the two partial page refresh?

  • Best way to update a table with separate values

    Hi, I would really appreciate some advise:

    I need to regularly perform a task where I update 1 table with all the new data that has been entered in another table. I cannot perform a complete insert because this will create data duplicated each time it works, so the only way I can think of is the use of cursors in the script below:


    CREATE OR REPLACE PROCEDURE update_new_mem IS
    tmpVar NUMBER;

    CURSOR c_mem IS
    SELECT nom_membre, member_id
    OF gym.members;
    CREC c_mem % ROWTYPE;


    BEGIN
    OPEN c_mem.
    LOOP
    SEEK c_mem INTO crec;
    EXIT WHEN c_mem % NOTFOUND;
    BEGIN
    UPDATE gym.lifts
    Name = crec.member_name
    WHERE member_id = crec.member_id;
    EXCEPTION
    WHEN NO_DATA_FOUND THEN NULL;
    END;
    IF SQL % NOTFOUND THEN
    BEGIN
    INSERT INTO gym.lifts
    (name, member_id)
    VALUES (crec.member_name, crec.member_id);
    END;
    END IF;
    END LOOP;
    CLOSE C_mem;

    END update_new_mem;



    This method works, but y at - it a (faster) easier way to update another table with new data only?

    Thank you very much

    Almost anything would be better than this treatment of slow-by-slow loop.

    You don't need a procedure, you should just use MERGE for this. See the examples in the section of the MERGER of the doc of the SQL language
    http://docs.Oracle.com/CD/B28359_01/server.111/b28286/statements_9016.htm

    MERGE INTO bonuses D
       USING (SELECT employee_id, salary, department_id FROM employees
       WHERE department_id = 80) S
       ON (D.employee_id = S.employee_id)
       WHEN MATCHED THEN UPDATE SET D.bonus = D.bonus + S.salary*.01
         DELETE WHERE (S.salary > 8000)
       WHEN NOT MATCHED THEN INSERT (D.employee_id, D.bonus)
         VALUES (S.employee_id, S.salary*.01)
         WHERE (S.salary <= 8000);
    
  • Best way to resolve this table?

    Lets say you're dealing with these two tables:

    CREATE TABLE VEHICLES
    (
    NUMBER OF VEHICLE_ID
    VEHICLE_NAME VARCHAR2 (100 BYTE),
    NUMBER OF MILES

    And some data for example as follows:

    Insert into VEHICLES (VEHICLE_ID, VEHICLE_NAME, MILES) Values (1, "Honda Civic", 75500);

    Insert into VEHICLE_PARTS
    (PART_ID, VEHICLE_ID, PART_TYPE, PART_DESCRIPTION, START_SERVICE_DATE, PART_TYPE_NAME)

    And you need produce a view that shows the flattened attached data where each vehicle has one row with columns representing their most recent part (which has a service as Start Date of null terminator).

    Like this:

    Car: Engine: tires:
    Honda Civic 1.6 VTEC Bridgestone Blizzaks
    Ford Taurus 3.5 L Duratec Nokian


    There he has a fast and efficient to do that?

    My current approach, which is the brute force method is to have a separate outer join for each column, I need to shoot with the condition of max (START_SERVICE_DATE) to get the current part for each type (engine, tires, etc...).

    but its so slow and painful code.

    I thought pivot but I don't think that Pivot help here since there is no aggregation going, right?

    Thanks for posting the CREATE TABLE and INSERT statements; It's very useful!

    I thought pivot but I don't think that Pivot help here since there is no aggregation going, right?

    Pivot is always aggregation; you take any number of rows in the table and only one line display. It is the aggregation.

    Anything with the partition could over aid? IM unfamiliar with this syntax

    Yes: ROW_NUMBER analytic function can help to identify the most recent line for each vehicle_id and part_type_name in vehicle_parts.

    Here's a way to do it:

    WITH     got_r_num     AS
    (
         SELECT     vehicle_id
         ,     part_description
         ,     part_type_name
         ,     ROW_NUMBER () OVER ( PARTITION BY  vehicle_id
                             ,             part_type_name
                             ORDER BY        start_service_date
                           )     AS r_num
         FROM     vehicle_parts
         WHERE     end_service_date     IS NULL
    )
    SELECT       v.vehicle_name
    ,       MIN (CASE WHEN r.part_type_name = 'ENGINE' THEN r.part_description END)     AS engine
    ,       MIN (CASE WHEN r.part_type_name = 'TIRES'  THEN r.part_description END)     AS tires
    FROM            vehicles     v
    LEFT OUTER JOIN     got_r_num     r  ON     v.vehicle_id     = r.vehicle_id
    WHERE       r.r_num     = 1
    GROUP BY  v.vehicle_name
    ORDER BY  v.vehicle_name
    ;
    

    You must add another column in the main query for each part. It's just one line of code, not nearly as bad but to join another subquery.

    Whenever you have a problem, don't forget to tell what version of Oracle you are using.
    The above query will work in Oracle 9 (and), but if you have Oracle 11, you'll want to use SELECT... PIVOT.

  • What is the best way to clear up the brightness of that horse without affecting the color?

    Screen shot 2012-12-30 at 6.41.55 AM.png

    Hi Matt-

    Unfortunately, the image you are working with a lot of solid black color data - this means that there is not much variation in tone to work with, as you expect to. However, I have provided a few steps below for you to experiment.

    1 using the quick selection tool, select only the area of the photo you want to brighten up - in this case, I chose the horse.

    2. go in Select > refine edge...

    3 use the tools to improve the outline to adjust your selection as needed (I would recommend clicking on the RADIUS Smart option).

    4. your selection active, click the fill/adjustment layer icon and select the curves. You can select other options in this menu as well if the curves does not give you the desired effect.

    5. set your curves (or other adjustments) for the look desired as you'd like.

    6. with your selected adjustment layer, click on the blending Mode dropdown at the top of the layers panel, and then select lighten (Alternatively, you can try any other mode of mix that gives you the look you want or brightness).

    7. below, you can see a side-by-side comparison of the images of the horse before and after. Because the black areas of the horse contains data of uniform color, there is no change. However, the bright sections of the horse became brighter and more dynamic while maintaining the tone of the original colors.

    If you want more information, here are two resources advanced on the change of the brightness of a picture:

    I hope this helped - if you need more help, feel free to post again. Good luck!

  • What is the best way to deal with a 'Implicit coercion' in a table to a sprite?

    Hi all!

    With the continued support of this forum, I'm getting closer to have a programme of work. I can't wait to be able to help others like me once I've finished learning the ropes of AS3.

    I'll briefly explain what I want to achieve and then followed with my question.

    Background

    I created a random number of 12 x 9 grid that fills each cell with an image, based on the numeric value of each cell. I also have a random play button that makes random numbers in the grid. The problem I am running became my click event of button to erase the current images off the grid in order to allocate the new (for example by removing the objects display battery in order to place the new ones in the same places).

    Question

    My question is this: what is the best way to manage an implicit constraint from a table to a sprite? I pasted my complete code below so that you can see how the functions are supposed to work together. My sentence is apparently not being able to use a value from array with a sprite (sprite represents the real layout of the grid on the pile of display while the table starts as a number that is assigned an image that must be transmitted to the sprite).

    ============================================================================

    Any help with this is greatly appreciated. Thank you!

    If you want to have an array of Sprites that you later clear that is fine. But this does not mean that your function should return to it.

    You need your function to return the sprite so that you can add it to the display list and everything what you need.

    So just have the function get Sprite, push it in the "toBeClearedInTheFutureArray" and then return a reference to the currently acquired sprite.

  • Best way to update the individual rows of a Table?

    I took a quick glance at a few examples, but did not get a clarification on this.  I am looking to have something close to a listbox control or the table to where I can update just one column of values to line a 1 time per second pace.  I'm looking to display our acquisition of data values in a table or a listbox control.  The single list box seemed to work well for that, but I couldn't use the row headers to list the names of channel beside the channel values.  I thought to link the values of cursor in two areas of list to do this, but did not find any info on it for the single list box.

    I have a few questions:

    (1) I have a 1 d table to where I want to use this data to constantly update the first column (with a multitude of lines) of a table.  I'm looking for the best route to not take too much time for treatment by doing this.

    What is the best way to update the individual rows of a table?   Invoke the node "Value of the cell value"... or is there another method?

    (2) why is that, after each iteration else, row values are deleted?

    Also, for adding additional channels originally arrray... it is better to use the 'Array' subset then the function "Construct the table" or function "Subset of the table" and "insert table"?

    See the attached example.

    Thank you.

    Jeff· Þ· Bohrer says:

    (2) why is that, after each iteration else, row values are deleted?

    Classic race condition.  dump the loop and node-p and just wire the 2D table on the terminal Board. !

    I don't see the race condition.  What I see is the table once the last element has been written for it all run the oil.  I saw looked it with point culminating performance on.

    But I agree entirely with writing to the Terminal.  It is a 1 d array, so you will need to use an array of generation and convert a 2D array in order so that he could write correctly.

    I understand how to create a view, but do not know how I handle updates/deletes/inserts with optimistic locking etc.

    Thank you in advance.

    The best way is to not use the tabular forms at all. Create an interactive report related to a form of single line based on a procedure that handles the DML and you will have a better way for users to access data and a much more robust maintenance page.

    If you need to use a tabular presentation, and then create a view to join the 2 tables, INSTEAD OF triggers on tables insert/update/delete according to needs and create the tabular form to the normal display.

  • Best way to update all the lines of a huge table

    Hi all

    I'm on Oracle 11.2 Enterprise edition.

    I asked a question, "assumes that there is a large table, say 3 GB size.» We need to update all rows in this table (e.g. col3 = col3 * 2), what is the best way to do this? »

    My answer was, there are 2 possible ways, depending on the number of indexes on the table

    (1) if there is a lot (or wholesale) index on the table OR the database is in FORCE LOGGING mode (due to log shipping), I just run an UPDATE command on the table and update all records. This will generate a lot of redo and undo, but we cannot do anything for indexes

    (2) if there is not a lot of clues, I'll create an empty table of the same structure (create table t2 nologging in select * from t1 where 1 = 2). Then, using an INSERT... AS SELECT... command, with the ' col3 * 2 "instead of col3, I insert any data into the new table with APPEND tip. Then create all indexes on the new table and finally, rename T2 T1

    In case the first solution, I can avoid the recreation of the index and save this I/O. In the case of newspapers, first solution makes more sense anyway.

    Second solution is logical, if we have the freedom of creating objects in NOLOGGING mode.

    What do you experts? I think in the right direction? or what?

    Thanks in advance
