  Hi Harshhh36,

  Usually, after the computer restarts, the drivers install automatically and it will stop the errors.

  You can also refer to the computer or the network card manufacturer's Web site to download and install the latest version of the drivers for the network card.

  You can also check in the updates of windows updates available for the network adapter driver.

  For more information, see the article:

• My DVD-RAM works too slowly on Satellite M70

  i've got Matt dvd - ram * one in my satelliteM70 installed in the secondary IDE channel.

  The "DMA if available", it has enable in Device Manager but the player is still in PIO mode then write a DVD disc it takes me 45 minutes. I deleted the second IDE channel and installed again, but it did not help.

  What can I do else?

  Burning speed you use when writing DVD? Do you use DVD-R, DVD - RW, or DVD-RAM media?

  Please do a little bit more information.

  By the way I M70 - 159 and I am very satisfied with the functionality of DVD - RAM drive. For me it is important that created DVDs are usable and I don't like about 5 or 10 minutes of more burning procedure.

• DF820 Digital Photo Frame slideshow works too slowly

  Hi all

  I have a frame of DF820 loaded with about 100 JPEGs on a SanDisk Ultra II SD 2 GB card map.  The size of the picture varies, but most are less than 500 KB.

  The slideshow will run no faster than about 25 sec/pic.  We see the response time even if I use the next or previous buttons.  I have truied to switching between various options, such as Original or Optimal, but nothing seems to affect it.

  For what it's worth, when I turn it on, it takes about 15 seconds to start the hourglass, and another 25 for the first image to load.

  Can someone tell me what could be the problem?

  Kind regards

  Never mind.  I changed the photos I put about 50 KB, and they load very well.  I'm always surprised how slow, it loads a file, but I guess that's by design.

• SDO_RELATE within PL/SQL query with rownum clause runs slowly on 12 c - works great on 10 g

  Hello

  I use the database 12.1.0.2 with a node 2 RAC on Windows.

  I am struck by a really weird performance problem with a particular query.  Bear with me while I try to explain...

  I have a chart with lines 30 sdo_geometry million, in 7 partitions with a local partitioned spatial index divided.  Called BIG_PARTITIONED_TABLE for this example.

  I query the table to search for one line with a geometry that is equal to the geometry of my request.  In this case I use sdo_relate with "mask = equal".  Instantly returns:

  SQL> select id, geometry
    2  from       BIG_PARTITIONED_TABLE o
    3  where      sdo_relate(o.geometry, sdo_geometry(2002, 2157, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 1),
    4     SDO_ORDINATE_ARRAY(604853.595, 692379.864, 604879.046, 692350.272)), 'mask=equal') = 'TRUE'
    5  and rownum = 1;
  
          ID
  ----------

  Elapsed: 00:00:00.10
  
  

  But if I put the same query in PL/SQL, so it takes 21 seconds:

  SQL> declare
    2     l_id number;
    3     l_geom sdo_geometry;
    4     l_window_geom sdo_geometry;
    5  begin
    6     l_window_geom := sdo_geometry(2002, 2157, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 1),
    7             SDO_ORDINATE_ARRAY(604853.595, 692379.864, 604879.046, 692350.272));
    8
    9     select id, geometry
  10     into l_id, l_geom
  11     from    BIG_PARTITIONED_TABLE o

  13     and rownum = 1;
  14
  15  end;
  16  /
  
  PL/SQL procedure successfully completed.
  
  Elapsed: 00:00:21.13
  
  

  If I remove the "rownum = 1", then it returns instantly:

  SQL> declare
    2     l_id number;
    3     l_geom sdo_geometry;
    4     l_window_geom sdo_geometry;
    5  begin
    6     l_window_geom := sdo_geometry(2002, 2157, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 1),
    7             SDO_ORDINATE_ARRAY(604853.595, 692379.864, 604879.046, 692350.272));
    8
    9     select id, geometry
  10     into l_id, l_geom
  11     from    BIG_PARTITIONED_TABLE o
  12     where   sdo_relate(o.geometry, l_window_geom, 'mask=equal') = 'TRUE';
  13
  14  end;
  15  /
  
  PL/SQL procedure successfully completed.
  
  Elapsed: 00:00:00.03
  
  

  If using sdo_equal instead of sdo_relate and keep the "rownum = 1", then it returns instantly.

  SQL> declare
    2     l_id number;
    3     l_geom sdo_geometry;
    4     l_window_geom sdo_geometry;

  Here is a comparison of the plans to explain.  First, here's the good thing, that is using the spatial index (BIG_PARTITIONED_TABLE_SPIND):

  select id, GEOMETRY
  FROM
  BIG_PARTITIONED_TABLE O WHERE SDO_EQUAL(O.GEOMETRY, :B1 ) = 'TRUE'
  AND ROWNUM = 1

           1          1          1     DOMAIN INDEX  BIG_PARTITIONED_TABLE_SPIND (cr=98 pr=0 pw=0 time=43250 us)
  
  

  Then the slow that does not use the spatial index.

  select id, GEOMETRY

  I tried adding an indication / * + index (o BIG_PARTITIONED_TABLE_SPIND) * / but that did not help.

  I am struck this issue during testing of upgrade 10.2.0.5 to 12.1.0.2.  The query works perfectly on 10g - we note only that this question on 12 c.

  I can't use sdo_equal as the real mask that we want is equal + dommagescausdspar + covers.  I'm just using equal here to simplify the test.

  I use "rownum = 1" because I want to just the first result.  In practice I can rewrite probably is a FOR LOOP, I get out after the first result, but that seems all just awful.

  Any ideas?  If anyone has seen anything like this before?  Its an optimizer delivers really so I'm going to cross post the SQL Forum after a certain time, but thought I would post it here first.

  Thank you

• SQL query simple SQL Developer takes, the wizzard of XE does not work

  Hello everyone
  
  I wrote this simple query that developer SQL works well, but when I try to run a report based on this sql query, it tells me invalid sql statement. It's true, maybe it's not valid because this IF clause in there... but Developer SQL seems to be very tolerant or includes more...
  
  I wrote this is because obviously if there is no Boss, ie = 0 then I would get an error when it division by 0, so I put that 0 just for selecting the right
  
  
  If count (bosses) > 0
  Select company, zip code.
  sum (Boss/staff)
  assessment
  Group of company, zip code
  
  Thank you very much
  
  Alvaro

  Ok. This should work:

  Select company, zip code.
  -case when count (staff)! = 0 here end sum (Boss/staff)
  assessment
  Group of company, zip code

  If this does not work, could you please explain, how your table looks like?

• SQL query for the region of the tree

  Hello

  I was wondering if someone is able to help me work on a SQL query, to format the data in the table required in a part of the tree... I've never used a tree and I'm fighting to get the right data (if possible).

  The data in the table looks like this:

  

  I want to put it in a tree, using level 1 level6 with a final layout that would look like this:

  

  As you can see, the data are formatted in level6 down in the tree, but are filled in the table from level 1. Not all of the columns will be filled, so level2 for anyone 4 (France) is the equivalent of level in the tree like level6 to person 1 (Spain).

  This is Apex 4.2.5

  Oracle 11.2.0.3.0

  Sample data:

  CREATE TABLE employees
     ( employee VARCHAR2(100),
       level1 VARCHAR2(100),
       level2 VARCHAR2(100),
       level3 VARCHAR2(100),
       level4 VARCHAR2(100),
       level5 VARCHAR2(100),
       level6 VARCHAR2(100)   
     );
  
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person1','Team One','Recruitment','Human Resources','Fictituous Company','Murcia','Spain');
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person2','Team Four','Testing','IT','Big Corporate','Hanover','Germany');
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person3','Big Corporate','Hanover','Germany', null, null, null);
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person4','Brittany','France', null, null, null, null);
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person5','Team Three','Testing','IT','Big Corporate','Hanover','Germany');
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person6','Public Relations','Government Agency','Brittany','France', null, null);
  
  

  Added example given.

  Hello

  Apex-user wrote:

  Thanks Frank, this is a good example, I can work with that! Your assumptions are correct.

  A question I came, however, is that I have a data segment that comes across poorly formatted so to speak... where only the lower levels (1-2, etc.) have been filled from the bottom up.

  An example of this data would be:

  1. INSERT INTO employees (employee, level 1, 2, level3, level4, level5, level6) VALUES ('Person7', 'One Team', 'Test', null, null, null, null);

  As you can see that if you rerun the select, the test team is now duplicated, both at the level of the root in the tree as it should.

  You are not sure if the sql can be adjusted to account for this, or if it's too hard?

  It is obviously a question of data and I am trying to solve this separately (extracted data from another system out of my control).

  Thank you!

  Sorry, I'm confused.

  You say that my assumptions were correct.  What includes supported that "If test ' occurs under 'IT' in a row, then the extent of the 'Testing' occurs, it must be under"IT "?  Right after you say that assumptions are correct, you give an example where 'Testing' occurs under 'IT' to a single line, but it is not less 'IT' to another line and where is 'One Team' under 'Testing' in a line, but is 'One Team' under 'Recruitment' in another row.

  When a situation like this occurs, how you cope?  Whenever you have a problem, please post the exact results you want from the given sample data, and an explanation of how you get these results.  If you don't know about what would be the ideal results, or if you are flexible on the exact results, then at least give an example and explain your reasons.

  Maybe you want to change the got_parent of subquery like this:

  WITH unpivoted_data AS

  (

  SELECT *.

  Employees

  UNPIVOT (node_name

  FOR lvl (level1 AS 1

  level2 AS 2

  level3 AS 3

  level4 AS 4

  level5 AS 5

  level6 AS-6

  )

  )

  )

  got_parent AS

  (

  SELECT c.node_name

  MIN (p.node_name) AS a parent

  Of unpivoted_data c

  LEFT OUTER JOIN unpivoted_data p ON p.employee = c.employee

  AND p.lvl = c.lvl + 1

  GROUP BY c.node_name

  )

  SELECT LPAD (' ' ')

  2 * (LEVEL - 1)

  ) || Node_name AS entity

  OF got_parent

  START WITH parent IS NULL

  Parent = node_name PRIOR CONNECTION

  ;

  In this way, if 'Test' is current 'IT' in one line, but not under what in another line, whether under would consider the 'IT' request and not to be a root.  If 'One Team' sudden 'Testing' in a line, but under "Recruitment" in another line, it will be (arbitrarily) consider it under "recruitment".

• A map of OWB (service line) SQL query

  If I trace a session, run a map OWB (base line), the trace file contains the actual SQL query?

  The problem with me is that when I execute this rank - based OWB card, is throw me an error CursorFetchMapTerminationRTV20007, BUT (most time consuming) when I take on the intermediate SQL insert query, it works very well (and also in a very short time)

  The executing State = COMPLETE

  message = text ORA-06502: PL/SQL: digital or value error: character string buffer too small

  CursorFetchMapTerminationRTV20007 = message text

  N ° of task errors = 0

  N ° task warnings = 2

  N ° errors = 1

  Since this card OWB (truncate insert) is the line in function of where I can't back-end of the generated pl/sql package request OWB so I was wondering if I trace the session, check the trace file, maybe I'll able to see the exact SQL query generated. But I wanted to confirm the same.

  Yes, the real run SQL in session will be in the trace file.

• Pool pane there problem with long sql query?

  Hello

  I use Jdeveloper 11.1.2.2.0

  In the application I'm developing, there is a long sql query to call (it's a function from a package, which may take a few minutes to run) and I want to display a progress bar for the user.

  The progress bar component is a "progress indicator" and the percentage of achivement is refreshed by a component 'pool' with 1-second interval.

  The two components are connected in a javabean.

  The function with the sql query is the javabean too.

  To run the sql query that is long on background I am calling from a thread, and the pool component get the advancement of the percentage of a pipe filled with the sql function.

  If the function to run is just a long loop of java operations the progress bar works fine, but if I put my long sql query instead, stop listener pool should be performed to stop long, s sql queryo progress are updated only at the end of the long sql query.

  You have any ideas?

  Thank you

  Thanks for your replies. Unfortunately, it was not the solution to my case, sql procedures to block the entire application while ADF awaits them at the end...

  To solve my problem, I finally used a PL SQL Job to call my sql procedure (dbms_job.submit).

  The application is released right after the call and the component of the pool is not more secure!

  Kind regards
