• The way of writing to a wireless bridge between two different routers.1:broadband and dir 2:dlink 605 l

  I want to bridge.and wireless I can't do that... Please send me how to write to a wireless bridge between two different routers.

  1:broadband
  and
  2:Dlink dir 605 l,

  Hi Mohammed Ehsan Jourah,.

  Thanks for posting the request in the Microsoft community forums.
  I understand that you need to know how to make a wireless bridge between two different routers

  What version of the operating system is installed on the computer?

  To connect multiple computers, install a network adapter in each and run a network CAT5 cabling to connect each one to a hub (and thus the other.) The computer that will serve as a transition will have a standard network card for wired and a wireless network adapter that will connect to the wireless (WAP) access point or gateway on the second network.

  A network bridge is software or hardware that connects two networks or more so that they can communicate. You can create only a single bridge network on a computer, but a bridge can handle any number of network connections.

  You can try the steps at the bridge between two different routers wireless.
  a. determine the coverage area. When using two or more routers, the coverage area should be divided, and each router should be placed in a central location in each subdivision. If you add a wireless router to an existing network, this may mean moving the first router.
  b. decide which router is the main router. The main router is connected to the Internet, a LAN cable or other networks. It should be as close to the wired network connections or who has the best line of sight to another wireless network. In addition, the main router should be a high range router, allowing large tables of State and more users.
  c. buy a spare antenna, as the antennas that come with most routers do not have very good range. Quality omnidirectional antennas can push the range and signal strength of each of the routers, which, in turn, will reduce the cost by allowing routers less cover more space overall.
  d. deploy the primary router carefully. This router is the most important and requires most of the time of installation and options. Set the WEP (Protocol) encryption Service Set Identifier (SSID) and wireless, set up the Internet connection and test the router with some clients (computers). Once you get the main router deployed, deploy other routers should be easy.
  e. deploy the secondary routers, which must be configured to operate in "mode of transition." Secondary routers should be deployed around the perimeter of a large area or 'hot spots' where users placed - for example, will convene a bench Park or the table.

• Utility FNDLOAD between two different servers

  Hi friends,
  For the phase of the UAT of our project, we have a new server (server with RedHat Linux ES4 HP).
  We need to migrate reports form the unfounded (IBM - AIX 5.3 p) server to the new.
  FNDLOAD works between two different servers?
  If not, please tell me the reason why it doesnot work between servers.
  I would also like to know if there is a way to migrate data between two servers.

  As indicated in the documentation, it does not work between servers. You export the metadata and get an output file. Then, you take the output file and transfer it to the new source. Complete with examples, including the necessary part of XDOLoader.

  When I tried using a General left join she gave much more duplicate rows.
  I have 100 lines in curepress, then I would have only 100 lines in the final result but I get my as 233 lines output, this may be due to CUREPRESSMASTER. CURINGGROUP = NAMINGMASTER. Certificate3 this condition.
  
  Please suggest me some queries.

  This may be due to CUREPRESSMASTER. CURINGGROUP = NAMINGMASTER. Certificate3 this condition.

  Yes. Because the above join result in one-to-MANY relationship. Look at your data

• The space between two different paragraph style

  Hello!

  I'm working on a book, and I would like to first of all a standard space between two paragraph styles.

  I have the paragraph of text and the reference point. I would like to put an extra space when a paragraph of text is followed by a reference point and vice versa.

  I usually do it in html with CSS, it's like

  p.text + p.citation {pad-bottom: 5px;} 
  

  My goal is to have a space between the text and citations, even if citations are multi point (and of course, without any paragraph empty additional)

  Is this possible?

  concerning

  Lila

  You probably need to two additional styles to represent the paragraph "first" that uses the text or styles of citation, with spacing before added, and text or reference style defined as following Style, like matches, for each, so that you can use for the first paragraph after a change. You can base teas on current styles and just add space.

• Screen flashes like a strobe light between two different "parts".

  Well, this is going to be hard to explain...

  The short version: my screen is spazzy.

  The long version: welp. It flashes like a strobe between two 'parts' as I call them. Part A is what I'm supposed to be viewing (browser, screen, scanner, antivirus, etc.) and part B being one of several things. The blue and black lines vertical, multicolored stripes, my desktop background. And it just flashes back. Sometimes when I move my mouse over the flashing area it goes back to what ever it is supposed to be (instead of my background OR task bar, it's just my taskbar) and, so, sometimes not. Sometimes, compounding the problem.

  It's driving me crazy.

  And not only it is completely in the path, it slows down my computer by my college courses online a pain in the thigh.

  I ran Webroot SecureAnywhere, CCleaner and Defraggler. All to nothing does not.

  Any help would be greatly appreciated. I'll even write a paragraph full dripping with disdain, if it's something stupid.

• Join between the tables with Order By

  Hello

  Sorry if my question has already been postponed. I Googled, but I can't find any solution.

  This is the version of my DB: database Oracle 10 g Enterprise Edition Release 10.2.0.3.0.

  I created 3 tables. They contain up to 4000 lines.

  When I join without the order of closed I got a very quick response (less than 1 second), when I simply add Order By it gets more than 30 seconds!

  The order is on a Date field from the first table.

  Here's my query:

  Select *.

  tableOne tone

  two tableTwo full outer join on tone.message_id = ttwo.message_id

  outer join complete tableThree on two.field_id = tthree.field_id

  tone.ts desc order;

  I have some difficulties to export the plan to explain it...

  Should I create any clue? where? on the orders of field? on the join field?

  Any tips? Thank you.

  NO, it would not be

  Oracle does not work like that.

  ORDER BY is always, really always done LAST.

  ALWAYS.

  The second statement is a JOIN EXTERNAL LEFT and not a FULL OUTER JOIN, so the results will be different.

  Why "assume you' yours 'assumptions' are always right?

  They are not. You were probably in your dipers when I was already performance in Oracle 6.0.33

• Left join with three-table join query

  I am trying to create a query that left me speechless. Most of the query is simple enough, but I have a problem I do not know how to solve.
  
  Background:
  We have stock stored in i_action.
  
  We have the attributes available for each type of action. The attributes available for each action are described in shared_action_attribute. Each type of action can have three attributes or none at all.
  
  We have the values stored for the attributes in i_attribute_value.
  
  An example says:
  We have a transfer action (action_code B4). The action of B4 entry into i_action records the fact that the transfer took place and the date at which he spoke. The attributes available for a transfer action are the function code receiver, the receiving unit number and the reason of transfer code. These types of attributes available and their order are stored in shared_action_attribute. The actual values of the attributes for a specific action of transfer are stored in i_attribute_value.
  
  Now i_action and i_attribute_value can be connected directly in action_seq in i_action and ia_action_seq in i_attribute_value. A left join on these two tables provides results for all actions (including actions that have no attributes) and assign values (see Query 1 below).
  
  There are two questions. First of all, I want only the first two attributes. To specify the attributes of the first two, I also i_attribute_value a link to shared_action_attribute (which is where the order is stored). I can build a simple query (without the left join) which connects the three tables, but then shares without attributes would be excluded from my result (see Query 2 below).
  
  The second problem is that I'd actually a row returned for each action with first_attribute and second_attribute in the form of columns instead of two lines.
  
  The final query will be used to create a materialized view.
  
  Here are the tables and examples of what is stored in the:

  Hello

  You can use an alias for column (such as staff_seq) in the ORDER BY. Unfortunately, it's the only place where you can use it in the same query, where it was defined.
  You can use it anywhere in the super-requetes, however, so you can still work around this problem in assigning the aliases in a subquery and GROUP BY (or other) in a Super query, like this:

  WITH   ungrouped_data      AS
  (
      SELECT ia.action_seq, ia.action_date, ia.action_code,

                                WHEN ia.action_code = 'G1'

                                   THEN VALUE
                                WHEN ia.action_code IN ('A0', 'A1')
                                   THEN '67089'
                             END IGNORE NULLS
                            ) OVER (PARTITION BY ia.ici_charge_inquiry_seq ORDER BY ia.action_date, ia.action_seq),

                WHEN display_order = '1'
                THEN VALUE

        LEFT JOIN i_attribute_value iav
             ON iav.ia_action_seq = ia.action_seq
        LEFT JOIN shared_action_attribute
             ON sactatt_sact_code = sact_code
           AND sactatt_sat_type = sat_type

  GROUP BY  action_seq
  ,       action_date

  There are other alternatives for special cases, but none of them work in this particular case.

• Extracting data from table using the date condition

  Hello
  
  I have a table structure and data as below.
  
  create table of production
  (
  IPC VARCHAR2 (200),
  PRODUCTIONDATE VARCHAR2 (200),
  QUANTITY VARCHAR2 (2000).
  PRODUCTIONCODE VARCHAR2 (2000).
  MOULDQUANTITY VARCHAR2 (2000));
  
  Insert into production
  values ('1111 ', '20121119', ' 1023', 'AAB77',' 0002');
  
  Insert into production
  values ('1111 ', '20121122', ' 1023', 'AAB77',' 0002');
  
  Insert into production
  values ('1111 ', '20121126', ' 1023', 'AAB77',' 0002');
  
  Insert into production
  values ('1111 ', '20121127', ' 1023', 'AAB77',' 0002');
  
  Insert into production
  values ('1111 ', '20121128', ' 1023', 'AAB77',' 0002');
  
  Insert into production
  values ('1111 ', '20121201', ' 1023', 'AAB77',' 0002');
  
  Insert into production
  values ('1111 ', '20121203', ' 1023', 'AAB77',' 0002');
  
  Insert into production
  values ('1111 ', '20121203', ' 1023', 'AAB77',' 0002');
  
  Insert into production
  values ('1111 ', '20130103', ' 1023', 'AAB77',' 0002');
  
  Insert into production
  values ('1111 ', '20130104', ' 1023', 'AAB77',' 0002');
  
  Insert into production
  values ('1111 ', '20130105', ' 1023', 'AAB77',' 0002');
  
  
  Now, here I want to extract the data with condition as
  
  PRODUCTIONDATE > = the current week Monday
  
  so I would skip only two first rows and will need to get all the lines.
  
  I tried to use it under condition, but it would not give the data for the values of 2013.
  
  TO_NUMBER (to_char (to_date (PRODUCTIONDATE, 'yyyymmdd'), 'IW')) > = to_number (to_char (sysdate, 'IW'))
  
  Any help would be appreciated.
  
  Thank you

  by the way: it is generally a good idea to store date values in date columns.

  One of the many reasons why store date information in VARCHAR2 columns (especially VARCHAR2 (200)) is a bad idea, it's that the data invalid get there, causing errors. Avoid the conversion of columns like that at times, if possible:

  SELECT     *
  FROM     production
  WHERE     productiondate     >= TO_CHAR ( TRUNC (SYSDATE, 'IW')
                            , 'YYYYMMDD'
                         )

• Several foreign key joins between two tables

  Hello
  
  I have a question about the creation of a repository.
  
  I have a date and a fact dimension. The fact table has about 10 columns in foreign key to the date Dimension.
  
  In this case I should create 10 aliases to create joins in the physical layer and MDB or y at - it another way to handle this situation.
  
  I ask this question because 10 aliases can get very confusing for me at the later stage of time when creating reports.
  
  With the help of OBIEE 10.1.3

  If you want to see in the industry as
  End date, start date, date etc. nearby
  you need to create 10 aliases for this purpose in the physical layer, make them drag in MDB and model, and then drag to the area of topic

  Score pls correct/good
