Hello

When there is a WHERE clause, it always comes after the FROM clause. (Joints and their conditions are part of the FROM clause).
Try this:

WITH     got_rnum    AS
(
     SELECT     cod_acct_no
     ,     amt_instal
     ,     ROW_NUMBER () OVER ( PARTITION BY  cod_acct_no
                               ORDER BY          ctr_stage_no       DESC
                       ) AS rnum
     FROM    loan_schedule
)
SELECT     m.cod_acct_no, m.amt_disbursed, m.bal_book
,     r.amt_instal             AS high_amt_instal
FROM     loan_mast     m
JOIN     got_rnum     r     ON     r.cod_acct_no     = m.cod_acct_no
                    AND     r.rnum          = 1
WHERE   m.cod_acct_stat = '8' ----------[this is condition is newly added to apply the same in production to fetch desired record]

  • 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

    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);

  • DVT:pivotFilterBar - how to get the selected values of the filter

    Hi all

    I have a question: how to get the selected values from the pivot table filter bar programmatically?

    I tried to use
    pivotTable.getDataModel().getDataAccess().getValueQDR(startRow, startCol, DataAccess.QDR_WITH_PAGE);
    but to the edge of the side DATA INCORRECTESdeclarations page, it seems that it will return the cached values.

    Environment: JDev 11.1.1.3.0 without tasks.

    Thank you
    Miroslaw

    Hello

    You can retrieve the value selected in the PivotFilterBar through the PivotFilterBar model, instead of dataaccess:

    Download the template of the bar pivot filter instance
    QueryDescriptior queryDescriptor = (QueryDescriptor) pivotFilterBar.getValue ();

    retrieve a list of criterion, each of them is used to fill each lov in the pivot filter bar
    ConjunctionCriterion conjunctionCriterion = queryDescriptor.getConjunctionCriterion ();
    List criterionList = conjunctionCriterion.getCriterionList ();
    for (int i = 0; i)<_criterionList.size(); i++)="">
    AttributeCriterion = (AttributeCriterion) criterionList.get (i) criterion.

    _selected is the currently selected value
    Selected object = criterion.getValues () .get (0);

    System.out.println (_selected);
    }

  • How to get the greatest value of the width and/or height of two open images?

    Re: Photoshop CS6, worm 13.0.1 (x 32) on Win 7 SP1 (64-bit) 16 GB of RAM

    My Photoshop workflow processes repeatedly changing the games of two images of an irregularly shaped object, centered on a white background. After completing the changes, each canvas needs to be cropped, then the two resizing to square canvas of the same size.

  • How to get the peak value

    Can I know how to get the 2 peak values v1 and v2 and 2 duration times t1 t2.

    Since there is a small amplitude noise, difficult to use the Max simplely.

    Thank you.

    I can't watch your vi now (I'm at work), but if your signals are long enough, you might consider a median filter.  You can set the number of points before and after use.  I found that it is useful for some smoothing problems (not all).

  • How to get the parameter values of a step type custom when I create file and adding a type of step seq

    I use lv 8.5 and teststand 4.0.

    I did a step type custom and recorded at the MyTypes.ini in pallets of type.

    I specified a default module by opening the properties of the custom step of *.ini type window, then I put some values of the parameters.

    T1) when I open teststand and I add the custom step type manaully in seq file, the labview module parameter values are represented.

    But, if to use file (create and add support prototype stage), the labview module parameter values has the default value.

    Using joint file, how to get the setting custom step type values I put in *.ini?

    Q2) each type of step are automatically by name through the use of LoadTypePaletteFilesEx. When I open teststand and I add the custom step type manaully in seq file, the module is loaded automatically. Inside the attachment, I use a prototype of charge and a fixed path where the module labview is to load the labview module.

    Can I load module automatically without using a prototype of charge or how can I get a dynamic path of type step?

    I solved Q1 for myself by using the mapping tab of the parameter within the configuration to the default module window.

    Everyone knows Q2?
