• Select the last value for each day of the table

  Hello!
  
  I have a table that contains several measures for each day. I need two queries on this table, and I'm not sure how to write them.
  
  The table stores the rows (sample data)
  

  *DateCol1                 Value       Database*
  27.09.2009 12:00:00       100           DB1
  27.09.2009 20:00:00       150           DB1
  27.09.2009 12:00:00       1000          DB2
  27.09.2009 20:00:00       1100          DB2
  28.09.2009 12:00:00       200           DB1
  28.09.2009 20:00:00       220           DB1
  28.09.2009 12:00:00       1500          DB2
  28.09.2009 20:00:00       2000          DB2

  Explanation of the data in the sample table:
  We measure the size of the data files belonging to each database to one or more times a day. The value column indicates the size of the files of database for each database at some point (date in DateCol1 European model).
  
  
  What I need:
  Query 1:
  The query must return to the last action for each day and the database. Like this:

  *DateCol1       Value      Database*
  27.09.2009        150          DB1
  27.09.2009       1100          DB2
  28.09.2009        220          DB1
  28.09.2009       2000          DB2

  Query 2:
  The query should return the average measurement for each day and the database. Like this:

  *DateCol1       Value      Database*
  27.09.2009       125          DB1
  27.09.2009      1050          DB2
  28.09.2009       210          DB1
  28.09.2009      1750          DB2

  Could someone please help me to write these two queries?
  
  Please let me know if you need further information.

• Take the minimum value for table data

  I'm storing test data in a table, with the hope that I can output the minimum value of the data. So far, I have used the table of max/min but can't make it work how I want. The test runs continuously in a loop of the holder. I get the minimum values in the table, but I would like to change the number of samples that the table contains, before it generates a minimum. The other option is that I run the test for a period of time (e.g. 3 seconds) and the table stores the data for this time then output 1 minimum value for the entire period.

  My current configuration VI is attached.

  Very appreciated

  Chris

  The size of the array in your VI is determined by the number of samples that you collect in your DAQ assistant, who is now 100 samples.  Never more, never less.

  How many samples do you want before you determine the minimum?

  Maybe what you really want to do is to build the table in the while loop and store it in a shift register, and when the loop has repeated enough times, then you take the minimum of built table.

• How to choose the maximum value in a column of a table by using the cursor and iteration

  Hello everyone
  I have a table loan_detail
  and a column inside loan_amount
  now I want to take the values in this table with the cursor, then using iteration that I want to take a max value of him using this slider
  Here is my table

  LOAN_AMOUNT
  
  100
  200
  300
  400
  500
  5600
  700

  I could make using the concepts of single loop, but when I tried to do by using the slider I wasn't able to do.
  Concerning
  Prost

  You can get the maximum value for a particular column in SQL, PLSQL needn't; Always avoid PLSQL so you can do it in SQL. But always as an example:

  declare
  number of Temp: = 0;
  Start
  for news in some loan_amt of loan_detail
  loop
  If (temp
  end if;
  end loop;
  dbms_output.put_line (temp);
  end;

• Get the highest value of acquired data

  Hi, how can I get the highest value of data according to data acquired using the accelerometer ADXL345 and LINX in LabVIEW?

  I want the highest data to be shown with a flag. However, the data being shown are always the last acquired data. My problem would be what happens if the highest data somewhere at the beginning or in the middle of all the acquired data? How to display the highest data using an indicator?

  Here's a look at my front, block diagram, and sample of the acquired data.

  

  

  

  From the front panel, the basic indicator of detected last poster 0.1929 (amplitude), which is the last value. But looking at the Excel file, the highest data are data which is 0.2013. The highest, I want to be displayed on the indicator not the last value. How do I do that?

  Thank you!

  I gave you an example of what you need to do - it is not okay if wire you the new value and the old value for the X or Y - it will always return the maximum of the two values so the order doesn't matter. It would have been more useful if you had posted what you tried the max & min. You need a registry to offset inside the loop (like I did with my while loop). If you only want to display the maximum value for each iteration of the loop for external, you must initialize the shift register by plugging a 0 to its terminal on the left. A shift register her pinned the value of the last run - probably not what you want here.

  24.10.2014.  23:51:10     1       2    25
  ...
  

  Let's say that the period is 21.10.2014. -23.10.2014. and I want to get the last balance recorded for zone 1. for each day. The result should look like this:

  Date         Time      Location  Box  Balance
  21.10.2014.  15:00:34     1       1    1237
  22.10.2014.  22:00:00     1       1    6742
  23.10.2014.  23:57:12     1       1    25
  

  So far, I managed to write a query that gives me the balance so that a SINGLE date (date more time in the table), but I need balance for EACH date in a specific period.

  My incorrect code (has not managed to implement "BETWEEN" for the dates...):

  SELECT TestTable.[Date], TestTable.[Time], TestTable.[Location], TestTable.[Box], TestTable.[Balance]
  FROM TestTable
  WHERE Time=(SELECT MAX(Time)
  FROM TestTable
  WHERE Location=1 AND Box=1 );
  

  TNX!

  NP

  Here's the correct query (just copy - paste):

  SELECT
  T1.Date,
  T1.Time,
  T1.Location,
  T1.Box,
  T1.Balance
  FROM TestTable T1
  INNER JOIN (
  SELECT
  MAX(Time) AS Max_Time
  FROM TestTable
  WHERE Location=1 AND Box=1 AND Date BETWEEN #10/27/2014# AND #11/1/2014#
  GROUP BY Date) T2
  ON T1.Time=T2.Max_Time;
  

  The problem is in the SELECTION within the INNER JOIN. This SELECTION selects the time max for each date, because we want this and then the entire table, we choose filelds we want, but now we have only fields with the time max.

  Here is a really good explanation of INNER JOIN if anyone is interested--> JOINT INTERNAL

  Peace!

  Why you don't want to use the analytical functions? Analytical functions, permitting the simpler, more robust and more effective to achieve these results, wouldn't you want that?

• Selection of lines with the range Paging VO

  Hello

  JDev 11.1.2.4

  I created a VO based on an OA. I added a transitional attribute in the original Version, this attribute is named Selelected of type Boolean initialized to false (default value Expression: false-Expression of Refresh value: false). That VO appears as an af:table. The attribute is displayed as selectBooleanCheckbox. The VO is set with an access mode of range Paging and a size of 28.

  < af:selectBooleanCheckbox value = "#{row.bindings.Selected.inputValue} '"

  label = "#{bindings." VwRhdPortfolioTranWrkSend11.hints.Selected.label}.

  required = "#{bindings." VwRhdPortfolioTranWrkSend11.hints.Selected.mandatory}.

  shortDesc = "#{bindings." VwRhdPortfolioTranWrkSend11.hints.Selected.tooltip}"id ="it1' autoSubmit = 'true '.

  valueChangeListener = "#{pageFlowScope.portfolioTransferBean.onWorkSelection}" >

  < f: validator binding="#{row.bindings.Selected.validator}"/ >

  < / af:selectBooleanCheckbox >

  The table shows the 25 lines. The user clicks one of the checkbox to select a line. The valueChangeListener is called with the new value (auto submit = true) as expected. Then the user scroll down for another "page" in the table, new lines are displayed. Then it scrolls to the first page. The previous selected checkbox is reset as not selected. The selection is lost.

  Is this expected behavior? If so how do you get a selection of lines with a VO of range paging.

  Thank you

  Try to create the transitional attribute in OT instead of VO.

  See you soon

  Does anyone know how to do this?

  Ok
  Try:

  WITH test_data AS (
  SELECT 1130 RecID, 16650 ProductID,  16650 VersionID, 1193  Category,  5 VersionNo, 'Category1' Type FROM DUAL UNION ALL
  SELECT 1130, 16650, 16650, 1205, 5, 'Category2' FROM DUAL UNION ALL
  SELECT 1130, 16650, 16650, 1242, 5, 'Category3' FROM DUAL UNION ALL
  SELECT 1130, 16650, 1130, 1193, 1, 'Category1' FROM DUAL UNION ALL
  SELECT 1130, 16650, 1130, 1205, 1, 'Category2' FROM DUAL UNION ALL
  SELECT 1130, 16650, 1130, 1242, 1, 'Category3' FROM DUAL),
  -- end test data
  max_data AS (
  SELECT RecID, ProductID, VersionID, Category, VersionNO, Type
    FROM test_data td1
   WHERE VersionNo = (
    SELECT MAX(VersionNo)
      FROM test_data td2
    WHERE td1.RecID = td2.RecID
       AND td1.ProductId = td2.ProductID))
  SELECT RecID, ProductID, VersionID, Category, VersionNO, Type
    FROM max_data
    UNION
  SELECT md1.RecID, md1.ProductID, td1.VersionID, md1.Category, td1.VersionNO, md1.Type
    FROM max_data md1
    JOIN test_data td1
   ON (md1.RecID = td1.RecID AND md1.ProductID = td1.ProductID)
  ORDER BY 1,2,3,5, 6
  
       RECID  PRODUCTID  VERSIONID   CATEGORY  VERSIONNO TYPE
  ---------- ---------- ---------- ---------- ---------- ---------
        1130      16650       1130       1193          1 Category1
        1130      16650       1130       1205          1 Category2
        1130      16650       1130       1242          1 Category3
        1130      16650      16650       1193          5 Category1
        1130      16650      16650       1205          5 Category2
        1130      16650      16650       1242          5 Category3
  

  And you simply:

  WITH max_data AS (
  SELECT RecID, ProductID, VersionID, Category, VersionNO, Type
    FROM test_data td1
   WHERE VersionNo = (
    SELECT MAX(VersionNo)
      FROM test_data td2
    WHERE td1.RecID = td2.RecID
       AND td1.ProductId = td2.ProductID))
  SELECT RecID, ProductID, VersionID, Category, VersionNO, Type
    FROM max_data
    UNION
  SELECT md1.RecID, md1.ProductID, td1.VersionID, md1.Category, td1.VersionNO, md1.Type
    FROM max_data md1
    JOIN test_data td1
   ON (md1.RecID = td1.RecID AND md1.ProductID = td1.ProductID)
  ORDER BY 1,2,3,5, 6
  

• The default value for a property with data of type boolean

  Hi all

  Is it a system preference setting, where the default value for a property with data of type boolean can be a Virgin? I want to keep the value by default in a vacuum, but every time I save the property even after empty selection, the default value changes to FALSE.

  

  In this case Boolean doesn't help you, you mayneed to create a chain of ownership and have true/false / "" as your list of values

• HP DV7-3063cl laptop PC: what is the maximum temperature for safe operation of the DV7 3063 cl with the upgrade of the 640 M CPU?

  I have recently restored a HP DV7 3063 cl laptop that died a hot mother (MB). I replaced the MB with a new Board of Directors of HP when the price has been reduced to $100, updated the CPU with an announced as new AMD 640 M and applied Arctic Silver on CPU and graphics chips. I put in 4 G memory cool, got the computer to work and installed Windows 10.

  The computer seems to run very hot and stopped twice from overheating during its first period of 2 weeks when it there was not a lot of calculating, fan was run at top speed at all times, and the laptop was high to allow good airflow below.

  According to the program of the Open Hardware Monitor, the CPU had reached 97-99 C a few times. I bought support cooling a player and that seems to help a lot, dropping the temperature to 20 ° C.

  What is the maximum temperature for safe operation of the DV7 with the upgrade of the 640 M CPU?

  Anything more than 90 c is too hot. You can specify the processor and the motherboard you have installed?

  Also if this from the Manual:

  Thermal paste is used on 1 CPU and heat sink section 2 that the services it. Thermal pads are used on the chip Northbridge 3 and 4, the graphical subsystem chip 5 contact Northbridge and graphics/heatsink contact 6. Thermal material replacement is included with all kits of spare parts of processor, heatsink and system board.

  So unless you have changed the cooling system to heat composed on the chip graphic you should have used a thermal buffer. Without the pad, it may leave just a small hallway and destroy the cooling properties. You can use a shim in copper or other piece of something metal to fill the void, but if you just put the heat sink down on the video chip you won't get optimal even with thermal cooling paste.

• Simulator Device.xml file has a tag with an attribute of memory, what are the optional values for this attribute of the os?

  In the Device.xml file, it starts with the tags of the os. Each os has a memory attribute. What are the optional values for the attribute memory?

  Can we really control the memory for the simulators?

  0x85000F03
  0x8C000F03

  These values refer to specific hardware configurations are simulated.  They should not be changed.

• Persistent for the subtraction of the background image collection (how to get the maximum value of each pixel in a series of images IMAQ)

  Hi all

  I have a system of LabVIEW which takes advantage IMAQ tools and features of the Vision Development Module.  A useful feature that I put in place is to be able to take a snapshot of the video stream and then subtract this single image among the subsequent images.

  What I want to do is to collect a series of images instead of one, and then create a unique image of these frameworks is just the maximum value of pixels in each pixel (a bit like a display persistent).

  It would probably be very easy to be implemented by converting the image to a table and then by doing math number on the table and then turning into an image, but I hope that someone here may know how to use the IMAQ/VDM tools to do this in a way more compact.

  Thank you very much

  MK

  How about using Max comparison IMAQ operation?
