How to define in the optional the clause, the maximum value of a colum

Hi!
I'm using select data block from database toolset.
I want to use optional clause wiring to import only the maximum value of the column 2.
E.g. to import only the values greater than 1 you have to wire a string like this col2>1. But i don't know which string i have to wire to iport the maximum value of this column.
Thank you in advance.

Hi Larson
To select row n you either need a certain value (e.g. an index or something you know is unique in row n) or you select all values and extract one row in LV.
So the first statement would be "SELECT * (* means all columns, you could also specify the columns as well) FROM data WHERE [a value = another value]. This would give you just the rows where the where-clause is correct. The other way is to select all data and just extract row n from the array you get from the recordset.
There might be other ways, but these are two solutions I just had in mind.
Manuals - just google the internet for SQL (Structured Query Language) and you will find lots of websites providing this information.
Hope this helps.

  • How to find out the maximum value

    Dear all,
    i have one query where in i have to calculate Excise Duty based on the  maximum  sales qantity of all materials with the corresponding sales value... i mean i wil get the maximum value of a individual material no matter how many sales has done.i wil pick up the maximum sales qty and the correspondig sales value....
    This im able to solve by taking the condition as TOP 1..
    Now my question is if the same material qty is sold with differnt value then i have to pick up the  Max value and as usual the sales qty..... plz help me out
    Material              Sales Qty              sales value
           3000                10 kl                   1000INR
           3200                15 kl                   1100 INR
           4000                20 kl                   1000INR
    in this case my query is picking up the max qty of  20 and the value 1000 INR as i had taken TOP 1 on Sales qty ....
    <b>
    But In the below example  for the same material i have to pick up the 3 rd row  where the sales value is maximum and the corresponding sales qty 10 kl</b>

  • How to find out the maximum value of one array

    hi all..
    I have one array that consists of some elements
    so I want the maximum value of the list ...
    if anyone knows this please help me..
    thanks..

    >
    If your array is already sorted, you can do a binary
    search.
    I think there are already methods to do that in
    java.util.Arrays. (?)
    If not, it's not hard to find an example on the net.
    A binary search will be more efficient.1. If your array is already sorted, you do not need a binary search. Either check the value of arr[0] or arr[arr.length - 1] depending on the direction of sorting.
    2. If your array is not sorted, try this:
    int maxValue = arr[0];
    for(int index = 1; index < arr.length; index++)
      if(arr[index] > maxValue)
        maxValue = arr[index];
    }

    Venu,
    In your query try creating a formula, with the value of each record as the key figure in the formula.
    In the aggregation tab select maximum in the exception aggregation dropdown and then select material as the reference characteristic
    then when you include material in the rows it will only display the maximum value.
    cheers

  • How do I identify the maximum length of video in iMovie which can be made into a dvd in iDVD, please?

    How do I identify the maximum length of video in iMovie which can be made into a dvd in iDVD, please?
    I made a sellection of video clips  > pressed on "share" > on iDVD >  after one hour of formating the message was under "project duration"  : "Your project exceeds the maximum content duration. To burn your DVD, change the encoder setting in the Project Info window."
    I have edited out some of the clips and waited anothe hour or so bu the same message appeared !
    I want to know in advance how long can be the video clip sellection for the quality of video chosen ( the best before HD).
    please help if ou can.
    thank you very much indeed.
    Michael
    North London

    It's trying to tell you to change the encoding setting:
    iDVD encoding settings:
    http://docs.info.apple.com/article.html?path=iDVD/7.0/en/11417.html
    Short version:
    Best Performance is for videos of up to 60 minutes
    Best Quality is for videos of up to 120 minutes
    Professional Quality is also for up to 120 minutes but even higher quality (and takes much longer)
    That was for single-layer DVDs. Double these numbers for dual-layer DVDs.
    Professional Quality: The Professional Quality option uses advanced technology to encode your video, resulting in the best quality of video possible on your burned DVD. You can select this option regardless of your project’s duration (up to 2 hours of video for a single-layer disc and 4 hours for a double-layer disc). Because Professional Quality encoding is time-consuming (requiring about twice as much time to encode a project as the High Quality option, for example) choose it only if you are not concerned about the time taken.
    In both cases the maximum length includes titles, transitions and effects etc. Allow about 15 minutes for these.
    You can use the amount of video in your project as a rough determination of which method to choose. If your project has an hour or less of video (for a single-layer disc), choose Best Performance. If it has between 1 and 2 hours of video (for a single-layer disc), choose High Quality. If you want the best possible encoding quality for projects that are up to 2 hours (for a single-layer disc), choose Professional Quality. This option takes about twice as long as the High Quality option, so select it only if time is not an issue for you.
    Use the Capacity meter in the Project Info window (choose Project > Project Info) to determine how many minutes of video your project contains.
    NOTE: With the Best Performance setting, you can turn background encoding off by choosing Advanced > “Encode in Background.” The checkmark is removed to show it’s no longer selected. Turning off background encoding can help performance if your system seems sluggish.
    And whilst checking these settings in iDVD Preferences, make sure that the settings for NTSC/PAL and DV/DV Widescreen are also what you want.

  • How do you tell the color value of a pixel in an image data

    Hi,
    Given a BufferedImage of type, say BufferedImage.TYPE_4BYTE_ABGR, how do you tell the color value of a pixel in the image?
    Specifically, in the following code:
    Raster imgData = image.getData();
    int x = imgData.getMinX();
    int y = imgData.getMinY();
    int width = imgData.getWidth();
    int height = imgData.getHeight();
    I want to search the raster looking for a specific color, e.g., Color.WHITE.
    According to the API, "getSample()" may be used for this purpose. But, how do you know which color band a band index parameter in getSample() refers to? Does band index of 0 always refer to the RED band? Does band index of 1 refer to the GREEN band? etc.
    I'd greatly appreciate any help you may be able to provide.
    Thanks,

    In the print dialog underneath the settings for number of copies and print range you should see a dropdown menu probably called Layout. If you don't see that look for a button labeled Details and click it.
    Under the Layout menu you should find an option labeled Printer where you will find Printer specific options. Look for something there. You might also find an option called Color which may have options you are looking for.
    If this doesn't help, go to the printer manufacturer's website and look for answers there.

    Arun

    Hi,
    You're on the right track using COUNT (*), but, for this job, you want the analytic COUNT, not the aggregate COUNT.
    "GROUP BY x, y, z" means that the result set will only contain 1 row for each distinct combination of x, y and z. Most aggregate functions (including COUNT) have analytic counterparts that get the same results without reducing the number of rows.
    Here's one way you can use the analytic COUNT function:
    WITH     got_cnt          AS
         SELECT    customer_name
         ,       father_name
         ,       gf_name
         ,       COUNT (*) OVER ( PARTITION BY  customer_name
                               ,                 father_name
                         ,           gf_name
                         )     AS cnt
         FROM       cif_migrate
    SELECT    customer_name
    ,       father_name
    ,       gf_name
    FROM       got_cnt
    WHERE       cnt     > 1
    ;PARTITION BY in analytic functions corresponds to GROUP BY in aggregate functions.

  • How can i get the all values from the Property file to Hashtable?

    how can i get the all values from the Property file to Hashtable?
    ok,consider my property file name is pro.PROPERTIES
    and it contain
    8326=sun developer
    4306=sun java developer
    3943=java developer
    how can i get the all keys & values from the pro.PROPERTIES to hashtable
    plz help guys..............

    The Properties class is already a subclass of Hashtable. So if you have a Properties object, you already have a Hashtable. So all you need to do is the first part of that:Properties props = new Properties();
    InputStream is = new FileInputStream("tivoli.properties");
    props.load(is);

  • How to set up the maximum number of messages on a queue programmatically

    Hi,
    I am using IMQ 3.5 to implement a message layer for one of my projects. I created a "Job Status Queue", which receives job status report from a java application every minute. But I just want to keep the most current status report instead of all the job running history. How can I restrict the maximum number of messages to 1 programmatically?
    Any suggestion or help will be appreciated.
    Xiaoyun Tang

    You can't limit the destination size programmatically, but you can do it administratively and associate a behavior to occur when the limit is reached. In your case it sounds like you want a queue, 1 message deep, and to discard the oldest message when the queue is full. When you create the physical queue on the broker you can specify these attributes (you can also update them on an existing queue). For example:
    imqcmd create dst -t q -n StatusQ -o maxNumMsgs=1 -o limitBehavior=REMOVE_OLDESTFor more information see Chapter 6 of the Message Queue Administration Guide. In particular the "Managing Destinations" section:

  • How can I get the edited value from the editor in JTable

    I have a JTextField added as an editor to a cell in JTable.
    I value gets changed when I press enter.
    but in actionPerformed of the JTextField when I say
    String txtEditorValue = txtEditor.getText();
    I am getting the old value. How can I get the edited value? Thanks.

    Hi,
    I guess, your understanding of how JTable works together with its models is not good enough - for example the method getTableCellEditorComponent(...) of the TableCellEditor interface is used to get the component, that should be used as editing component - its second parameter is a value that should be used to setup the editing component - it is normally not the editing component itself.
    JTable uses an underlying TableModel to store the cell values - if you have edited a cell, JTable gets the value of the editing component by itself and stores it in the TableModel using its setValueAt(...) method. To retrieve this data you only need to query the TableModel using row and column of this cell as parameters
    say jt is your JTable, and row and column are the row and column of the cell - so to get the value, simply use
    Object obj = jt.getModel().getValueAt(row,column);
    if you know, that there is a String in this cell use
    String str = (String) jt.getModel().getValueAt(row,column);
    The editor component is used for the view of the JTable - you only want the data, which is stored in the model - you don't have to deal with the GUI components in this case.

  • How can i pass the Input value to the sql file in the korn shell ??

    Hi,
    How can i pass the Input value to the sql file in the korn shell ??
    I have to pass the 4 different values to the sql file and each time i pass the value it has to generate the txt file for that value like wise it has to generate the 4 files at each run.
    can any one help me out.
    Raja

    Can you please more elaberate., perhaps you should more elaberate.
    sqlplus is a program. you start it from the korn shell. when it's finished, processing control returns to the korn shell. the korn shell and sqlplus do not communicate back and forth.
    so "spool the output from .sql file to some txt file from k shell, while passing the input parameters to the sql file from korn shell" makes no sense.

    Dear Friend,
    Here when you have the callableSattement as ?=proc(?), the first ? is an output parameter. So you should register it as out parameter using registeroutparameter.
    Then you can get the value from the outparameter using callablestatement.getXXX().
    Try that way.
