  Specifically, the two simple solutions provided were:

  1 using the row_number, entitled Oracle ranking based on descending order of the inside telephone each empnum group. And finally selects the lines which has least rank (of least since that order is descending for phone).

  SQL > column alternatecontact format A20;

  SQL >

  SQL > SELECT empnum, alternatecontact, relationship, phtype, phone

  2 from (SELECT a.*, row_number() over r (PARTITION BY empnum ORDER BY phone / / DESC))

  3 FROM xxc_contact one)

  4. WHEN r = 1

  /

  EMPNUM ALTERNATECONTACT RELATIONSHIP PHTYPE PHONE

  Daryl Dixon EN work 7777777777 123457

  Home 123458 Maggie Greene CH 6666666666

  2. with the help of MAX, Oracle automatically assigns the maximum phone for all the rows in each group of empnum. And finally selects the rows with the maximum phone. Order by clause is omitted here intentionally. You can find out why.

  SQL > SELECT empnum, alternatecontact, relationship, phtype, phone

  2 (SELECT a.*, MAX (phone) over (PARTITION BY empnum) rn FROM xxc_contact one)

  3 WHERE phone = rn

  4.

• How to retrieve a single record from access by program?

  I need to recover a single access record. I have two columns, 'Sess' and 'Topic' in my database. I want back the Session number ('Sess') for a particular topic and post it on the front panel. I wrote the attached VI based on an example I found. This VI contains the number of the Session for the first record, but I can't understand how to identify a search for a specific record in the table.  Thank you!

  Do a google search for «sql tutorial» You need to learn how the SELECT statement. The general syntax is:

  SELECT column_name (s)
  Table_name FROM
  WHERE column_name operator value

• Reading time to fetch multiple records vs. single record

  Hi all

  I have an application where I need to get several records, I use an SMU-5185, and basically, the problem is that it takes too long to retrieve multiple records, I did a test to measure the time it takes for the reading of the hole 32 MB of data and results.

  Parameters:

  Records to Fetch = 8192 (maximum 1 page = 4 KB, 8192 Records = 32 MB)

  Fetch time = 1100 ms

  Records to Fetch = 1

  Samples to Fetch = (2 ^ 25-1500) = 32MB

  Fetch time = 70 ms

  So, I want to know why it takes more time to get the multiplerecords if both are reading the same amount of data? Is there something I can do to decrease the recovery time?

  Thank you

  Hi Rodrigo,

  In fact, I think that the rate of release should be out of the equation, as in the while loop I wait until the end of the acquisition,

  You're absolutely right, I apologize for this oversight.

  I'm you test your code and see several times (about 930ms) Fetch when only pick a channel.  As soon as I specified two channels, the recovery time is an order of magnitude smaller (around 90ms).  Change the sampling frequency, fetch timeout and record length do not seem to affect this disparity in the order of magnitude.

  So to reiterate:

  In the case of single record , changing from one channel to both channels double recovery time.  It's what I expect.

  In the case of multi recording , changing from one channel to both channels decreases the time of recovery by an order of magnitude.  I don't think that.

  Furthermore, when I test in the example shipping niScope EX Acquisition configured standard I do not see this effect.

  (1) can you confirm that, in the case of multi account for your tests, you see that the recovery time reduced when you specify two channels instead of one?

  (2) can you confirm that you are not able to replicate that in the example Acquisition set up ?

  I have tabled a CAR 350194 to address this behavior more with R & D, but unfortunately I can't promise a timeline for the resolution.  I recommend at this stage unless you change Acquisition is configured when you set up your code instead of starting from scratch.  Support at home OR you can call at any time to check the condition of this CAR.

  To answer your question of why a use case takes more time than another, it will take more time to study according to the guidelines of this CAR.  We have already mentioned there is some overhead involved with multi-record fetch, but whether or not the time more or less long you see are good times is something that R & D will have to answer.

  Please let me know if you can confirm what I see by testing.

• SQL query to retrieve the same record because no. boxes

  Hi all

  I have a table of Bill XXINV.

  the columns are

  INVH_NO INVH_ITEM_CODE INVH_QTY INVH_BOXES

  1122                XXITEM1                    1                    5

  1123                XXITEM2                     2                   6

  I can do a sql query so that I can retrieve the same records repeated as number INVH_BOXES.

  Select * from XXINV

  where invh_no = 1122

  output:

  INVH_NO INVH_ITEM_CODE INVH_QTY INVH_BOXES

• DataGrid with a single record

  I have a main table on a single server and services by a session bean.   I have detail data on a second server and services by another session bean.   So, I have a dataGrid that displays the main table and then when a folder is selected in the grid of master data, then a request is sent to retrieve the detail data from the second server.   And as long as there is more detail for the master records selected record, the second grid data displays this data very well.   But if there is only a single record, for some reason any the detail dataGrid is not updated.   And now, if the first selection has only one folder, then it displays nothing.  What it should display at least one folder.  If you select the one that has more than one detail record, then he who does that one record of retail, it displays the last series of detail records that had more then a record.   Which is incorrect.   Its as if the call to fetch the new recordset has never been called.   And even if I select a master record that has more than one record of detail and then select another main record which also has more than a detail record, then it displays correctly.

  My master datagrid has a choice to change manager which is where I call for detail data extraction:

  		protected function peopleGrid_selectionChangeHandler(event:GridSelectionEvent):void
  		{
  		getPlacesResult.token = cSOracleBean.getPlaces (peopleGrid.selectedItem.id);
  		}

  on the detail data grid, data binding is:

  < s:AsyncListView list = "{getPlacesResult.lastResult}" / >

  I haven't used flex for a while, but the result will not be a collection but a single element. If I remember correctly, the trick is to create a collection, place the item inside and assign the grid data source using this collection...

• Find the lines with a single record

  Sorry for the description of the thread crap, I couldn't think more concise and useful.

  This is my sample data (using Oracle 11.2.0.3):

  WITH tbl_data AS
  (SELECT 1234 acnum, 'bob customer' party_name, 6565 party_id, 'BILL_TO' site_use FROM DUAL UNION ALL
  SELECT 4234 acnum, 'cheese waffles' party_name, 423423 party_id, 'SHIP_TO' site_use FROM DUAL UNION ALL
  SELECT 1223 acnum, 'terry trees' party_name, 32423 party_id, 'BILL_TO' site_use FROM DUAL UNION ALL
  SELECT 1223 acnum, 'terry trees' party_name, 32423 party_id, 'SHIP_TO' site_use FROM DUAL UNION ALL
  SELECT 1223 acnum, 'terry trees' party_name, 32423 party_id, 'LEGAL' site_use FROM DUAL)
  select * from tbl_data;
  

  I would like to return only records that have a single address or a single SHIP_TO, but not records that have both an address AND SHIP_TO.

  Something as simple as a condition at the end of:

  WHERE site_use = 'BILL_TO' OR site_use = 'SHIP_TO'
  

  Not obviously doesn't work because it returns all rows with the address or SHIP_TO, rather than those with a single GOLD the other.

  I need to find data on our system where customers have a single record, but not both and am stuck working logic.

  Any advice would be much appreciated.

  Thank you very much

  Hello

  Thanks for posting the sample data.  Don't forget to post the exact results you want from these sample data.

  "Record" is not a term of standard database.  Explain what you mean by the latter.

  Depending on what you want, here's a way:

  SELECT acnum

  OF tbl_data

  WHERE site_use IN ('address', 'SHIP_TO')

  GROUP BY acnum

  HAVING COUNT (DISTINCT site_use) = 1

• Pls help: SQL Loader support only a single record

  Hello!!!

  I'm trying to insert data into a table using SQL Loader.

  I entered on the command line,

  Post edited by: 3cd7ad85-b56c-4a9c-ae91-83be047aac2c

  Continue_load can only be used with direct path, unconventional path.  You must specify the record terminator and terminator of field, which is the same when your data are only a single column.  Please see the example below.  As for your digital problem, as you can see, it does not reproduce below.  Your problem could be due to many things.  He might try to read something else that what you think, he tries to read, because of something else being wrong.  It is possible that you need to use:

  (msisdn "to_number (ltrim (rtrim (: msisdn)))")

  to remove the leading and trailing spaces and convert it to a number.  You must provide a copy and pasting a full example, as I did below.

  -loading_data.dat content:

  233207332711 233208660745 233200767380

• Find and change a single record in the database

  I create a few forms that access an Access database that will be used to enter data into the database.  I am able to open the database files and scroll through records one at a time and have added features to be able to search and display a single record.  The problem I'm having is when I load a single record and then modify that file, I can't save the changes to the record, in other words, the record is not updated on the database.

  I can add new records and modify records as long as I scroll to them using the. next(),. last(),. first() and. previous() orders; However, when I insert a single record I can't figure out how to save the changes made to that record in the database.

  Here it is:

  xfa.sourceSet.DataConnection.open ();

  xfa.sourceSet.DataConnection.first ();

  var oDataConnList = xfa.sourceSet.DataConnection.nodes

  var oDataConnList.length = nCount;

  for (var i = 0; i)< ncount;="">

  If (CurrentRecord.rawValue! = SearchField.rawValue) {}

  xfa.sourceSet.DataConnection.next ();

  }

  }

  This establishes the data connection, made sure that it starts on the first record, counts the number of files and of volutes each record until he finds the one the user sought!

  Hello. I have two tables different 'address' (home and work). In some cases, a person will have a record in the two arrays 'address', while some people will have only a record in one or the other. I want to return a single record set by b.SID. So if a person has a criminal record in the two tables then I'm just grabbing a name and an address. How can I do this?
  
  Select b.SID, b.address

  where b.name = b.SID
  UNION
  Select b.SID, b.address
  people, work b

• Retrieve a single value from a file .lvm

  I have a large batch of files of worksheet whose name is a timestamp. I am writing a program that will get the value of a specific cell (the same cell in each file), coupled with the timestamp and each of them as a pair of coordinates, then save in a master spreadsheet. The goal is to extract a point each of the 700 files I and compile them into a single file.

  However, I've never used Labview to read the files before. I saw some stuff on how to read an entire worksheet in a table, but I was wondering if there was a way to say to Labview to look into a file and extract a single value. I open .lvm in Excel files, so, in my mind, I would be taking, for example, cell D2. Is this feasible? Should I read the entire worksheet in an array and use the index to pick it up on the table? If I do, how I would specify cell J2 as an array index (I have no experience with the berries in Labview either). In addition, if you have any tips on how to record easily 700 pairs of coordinates, that came together in the order, to a single spreadsheet, that is my next task.

  Essentially- I need to extract a single value of a spreadsheet in, ideally, the simplest possible. In addition, pointers on how to save the numbers gathered at each iteration of a while loop to a single worksheet are welcome.

  Thanks in advance for the help!

  FYI I have LabView v8.6

  You can't say LabVIEW to 'out' a specific 'cell' more you can tell Notepad to do. the .lvm files are just text files. When you open them in Excel, the column separator (default tabs) show to put the values in columns. In LabVIEW measurement file VI reading to read .lvm files. It creates the dynamic data, wrong data type that is next to useless. You will need to convert this type of data in a table by using the function convert of DDT. Or, you can use the VI read spreadsheet file. This will give you a table directly. You can just remove the specific item using the table to Index.

• Can I add multiple documents to the signature of a single record EchoSign?

  If my client is a television network, and they want to sign individual agreements for all of their affiliates, can I add all those separate agreements to an email? Or the customer must obtain an email separately for each station agreement? For example, Customer Contact even get 50 emails (for the 50 affiliated stations), coming one after the other and say 'sign this Document. EchoSign supports uploading multiple documents to a recording of "agreement"? Otherwise, the process of 'ease of use' electronic signature could backfire a lot of time...

  Hello

  Yes, you can add separate email agreements. EchoSign will automatically add the documents in a single transaction, then you can manually place the signature for each agreement fields separately.

  You can attach a total of 100 pages and size should be 10 MB or less (can be adjusted according to the type of subscription).

• Getting a list instead of a single record.

  Hello Experts,
  
  I'm trying to get a record in a table with the most amount of money. I used the following query to get the most out of money at the table, and he gave me the results.
  
  SELECT MAX (auction_item.item_highest_bid)
  OF 'auction_item '.
  
  I also need more of two fields in the same table. Item_id and seller_id. Now what happens, but when I write the SQL code following that I get a list of records instead of ONE record with the largest amount of money.
  
  SELECT MAX (auction_item.item_highest_bid),
  auction_item.item_id,
  auction_item.seller_id
  OF 'auction_item '.
  Auction_item.item_id GROUP,
  auction_item.seller_id
  
  Can please someone shows me what is the problem with my request and how I can get a SINGLE instead of the list record.
  
  Thank you very much in advance.

  There are several ways to get this information - subqueries sql analysis. A lot of it is based on the data.
  Is it possible that two or more records have the same MAX (auction_item.item_highest_bid)? And if so, how is - this be handled? I make a few assumptions about item_id and seller_id... so take with a grain of salt

  Either way... you must read about GROUP BY and aggregation in sql as this scenario is explained in the documentation/books.

  Without the benefit of a database to test this, here are a few ideas

  SELECT MAX (auction_item.item_highest_bid),
  auction_item.item_id,
  auction_item.seller_id
  Of auction_item
  WHERE auction_item.item_highest_bid = (SELECT MAX (i_auction_item.item_highest_bid)
  Of auction_item i_auction_item
  WHERE i_auction_item.item_id = auction_item.item_id
  AND i_auction_item.seller_id = auction_item.seller_id)

  Or

  SELECT i.item_highest_bid, i.item_id, i.seller_id
  FROM (SELECT a.item_highest_bid, a.item_id, a.seller_id
  Of auction_item one
  ORDER BY a.item_highest_bid DESC) I have
  WHERE i.rownum = 1

  Or

  SELECT i.item_highest_bid, i.item_id, i.seller_id
  (SELECT a.item_highest_bid, a.item_id, a.seller_id, ROW_NUMBER() over (ORDER BY a.item_highest_bid DESC) bid_rank
  Of the auction_item one) I
  WHERE i.bid_rank = 1
