Sum on a column in a collection based report

• Any method to create a total SUM of a column whose values based on LAG?

  I have a question here, and the challenge is to explain my situation well. I am developing a workbook that shows by project and month, the cost of this period and the change in the cost of the previous period. I want a total SUM on the columns of this period cost and cost change in prerequisite Mth. So what I want to do resembles something like this--
  
  Months of project cost this time Chg prior Mth cost
  
  ABCDE Jan $50,000 NULL (since no line before)
  ABCDE February $ $75,000 25 000
  Mar $60,000 ABCDE - 15 000
  ------------------------ ----------------------------------------------
  Total of $ $185,000 10 000
  
  I do the Chg of cost of prior Mth as a new calculation and use the formula insert model process to use the model of the difference f (x) to create my calculation. Who is working just great. If you look at the underlying code for this new section, you can see the LAG function used in the calculation of this value. I'm late to a single line, as you can see in the example above.
  
  I can create a new total and take a NAP in the cost column this time and get the right answer (the $185 000).
  
  The problem that I am running is that I get nothing when I try to summarize my prior Mth column cost Chg. The result is just empty (prints the text of the total, but no amount).
  
  My thought is that the NULL row in this column was to spoil the AMOUNT of work. So, I created a new calculation and said CASES WHERE prior cost Chg of Mth IS NULL THEN 0.00 ELSE cost Chg of Mth prior. So I get a new column with the same numbers, except for the first line, where I now have a 0 instead of NULL. Then, I created a new total (SUM function) on this new column. Heck. Same result with regard to the other column. I do not receive an amount.
  
  Everybody run on an issue to try to sum a column of numbers being calculated from a SHIFT function in discoverer? Any suggestions on how I could get a SUM to calculate correctly to this column cost Chg prior Mth? Or have I met one of those irritating questions "cannot manage in discoverer?
  
  Of course I can export the workbook results run to Excel and create the calculation in there, and that works fine.

  Hi John
  Thanks for the question and great information. That really helped. I love this kind of questions. They make me think :-)

  Just a thought but have you tried to change the AMOUNT for a sum of CELL?

  The SUM will try to assess the LAG on the total that would be invalid as, at least in theory, the SUM of the CELL must literally add the values.

• Calculate the sum of the columns

  Hello!
  
  Am using jdeveloper 11.1.2.1
  
  I created a table VO based EO. I need to calculate the sum of the column named price.
  
  I use the expression PoView.sum ("Price"). In this PoView is the name of VO and the price is the name of the column.
  
  While spin AMModule I got an exception like
  
  PoView name not found in the given object.

  Hello

  You must use the name accessor EO or VO instead of the name of VO.

• Update of the collection based on (wwv_flow.g_f01) report

  Hi all
  I have a page in my application that contains 3 standard reports based in a collection. There is a main report and from there you explore the other report, and from there you can go down to another (3rd report) that I'm trying to update a member of the collection based on an lov. I don't know how to insert the value from the lov in the 3rd report.
  
  
  Select seq_id
  IN CURR_SEQ_ID
  of apex_collections
  where collection_name = "ARGYLL_INVOICES."
  and c001 | C002 =: P12_EPSB_JE_HEAD_LINE_NUM;
  
  apex_collection.update_member_attribute (p_collection_name = > 'ARGYLL_INVOICES',)
  p_seq = > CURR_SEQ_ID p_attr_number = > 17, p_attr_value = > "EDMO");
  
  It works fine, but of course, it is hard coded. I would use the api wwv_flow.g_f01 but I can't make it work with my rudimentary understanding of this api call.
  
  apex_collection.update_member_attribute (p_collection_name = > 'ARGYLL_INVOICES',)
  p_seq = > CURR_SEQ_ID p_attr_number = > 17, p_attr_value = > wwv_flow.g_f01 (a few references here);
  
  
  Any guidance would be most appreciated.
  
  Thank you

  Here is an excerpt from a quick tutorial on the use of collections. I'm including the section of the report you can see the corresponding values:

  SELECT rownum, apex_item.hidden(1, c001),  --Key ID
       apex_item.text(2, c002, 8, 8) VALUE1,
       apex_item.text(3, c003, 3, 3) VALUE2,
       apex_item.text(4, c004, 8, 8) VALUE3,
       apex_item.date_popup(5, null,c005,'MMDDYYYY',10,10) MY_DATE
  FROM APEX_COLLECTIONS
  WHERE COLLECTION_NAME = 'MY_COLLECTION'
  

  It will be a report as a SQL report - you are just pulling the data from the collection. You can always ask the nice formatting, naming, sorting, etc. of a standard report. In the report, the user will have 3 values 'text' and a Date with the date picker. You can change the format, make sure just to change all four procedures.

  What is critical to note here are the numbers that come just before the column names. These numbers become identifier in the table used to capture data. What is APEX is creates an array of up to 50 items designated as F01 - F50. The F is static, but the number that follows, it matches the number on your tax report above, IE, F01 will contain the primary key value, F02 will contain the first numeric value, etc.. Although not strictly necessary, it is advisable to assign these values so you don't have to guess.

  A note more: I try to align c00x values in the column with the values of F0X collection in the table to stand straight, but they are values that do NOT have to match. If you have a request that you think could get developed, you can leave gaps where you want. Remember, however, that you have only 50 columns of table to use for the data entry. It is the limit of F0X table even if a collection can have up to 1000 values.

  Now, you need a way to capture the user input. I like to create this as a PRELIMINARY procedure CALCULATIONS/VALIDATIONS in this way the user can see what they changed (even if it is false). Use Validations to intercept errors.

  declare
    j pls_integer := 0;
  begin
  for j1 in (
    select seq_id from apex_collections
    where collection_name = 'MY_COLLECTION'
    order by seq_id) loop
    j := j+1;
    --VAL1 (number)
    apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
        p_seq=> j1.seq_id,p_attr_number =>2,p_attr_value=>wwv_flow.g_f02(j));
    --VAL2 (number)
    apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
        p_seq=> j1.seq_id,p_attr_number =>3,p_attr_value=>wwv_flow.g_f03(j));
    --VAL3 (text)
    apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
        p_seq=> j1.seq_id,p_attr_number =>4,p_attr_value=>wwv_flow.g_f04(j));
    --VAL4 (Date)
    apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
        p_seq=> j1.seq_id,p_attr_number =>5,p_attr_value=>wwv_flow.g_f05(j));
  end loop;
  end;
  

  Clear as mud? Walk slowly through it. The syntax tells APEX Collection (p_collection_name) (p_seq) line, then what attribute/column (p_attr_number) updated with the value (wwv_flow.g_f0X (j)). The number of the attribute is the column number of the collection without the 'c' on the front (IE c004 in the collection = attribute 4).

  See if this helps answer the question. You'll notice that I'm grabbing values SEQ_ID of the collection and a loop through them one at a time and using them to find the index of the JavaScript array holding the corresponding value, I need to use in the update part.

  A few quick hits.

  You can merge the two for loops

  You have not need one of the constants 1 and 2 in the index table.  They will solve automatically when you expand on the index picture, once you have wired to 0 in the column index.

  It seems a lot of handling additional table spent unnecessarily.

  See below.  I did not try to duplicate your code to see how it actually works, but I believe that I have attached will give the same result with less steps.

  

• Is there an alternative way to compute the sum of a column without accessor view

  Hi Experts,

  JDev 12 c,

  I have a column A and I'm total calculation of column A with the same VO as a view accessor. And calculating as below

  EmployeeViewAccessor.sum ("ColumnA").

  But this way, it loads the VO 2 times as it loads the accessor aswell.

  So is there an alternative way to calculate the sum of a column.

  Thank you

  You cannot change this collection. You must create a new. And you use no reserved words (for example, the "group") for the names.

  DECLARE

  CURSOR c1 IS (SELECT e.*, cast (null as varchar2 (10) GroupName, cast (null as name varchar2 (10))))

  FROM emp e);

  The collection must be inserted before you can use this topic.

  In the Begin block, you have to collect a loose and insert inside: something like

  BULK COLLECT INTO l_array
  FROM ALL_USER

• sum of a column of the dimension

  Hello
  If my requirement of report said we get SUM (Treasury of column) of the dimension table then can we do it? I have undersatnd that function must be used for measures in fact table. What are we doing to reach the sum of the columns in the dimension table? The report tries to compare the sum (column done) sum (dimension columns). Earlier when I used the sum on the column dimension function he gave no precise results. Please advice.

  Unfortunately, I could not explain this matter in a simple unique way, without seeing exactly the report and generated queries

  In the simple table, OBIEE is supposed to do something like this (I assume you put the attribute of the year, money and a measure of 'real')

  "+ select +".
  + Year +.
  + Sum (cash) +.
  + Sum (fact measure) +.

  + Of +.
  + time_dim_table, +.
  + cash_dim_table, +.
  + fact_table +.

  + where (joins).
  + Group by year +.
  "

  You can check if the physical demand looks like this, in order to understand the results.

  In the PivotTable, it's totally different.
  Your physical demand will be no aggregation: so what will:

  "+ select +".
  + Year +.
  + Cash +.
  + Sum (fact measure) +.

  + Of +.
  + time_dim_table, +.
  + cash_dim_table, +.
  + fact_table +.

  + where (joins).
  + Group by year, money +.
  "

  But, OBIEE then apply logic calculatiosn to display goods results in the PivotTable.
  Who can explain the different results.

  But don't forget that told you right: avoid the aggregation on the dimension attributes. You can sometimes has good results (ex: using the pivot, or other), but it's not really the best way to make your reports. If you often need a "sum (cash"), create a new table of logic made with the 'picture of cash' (even if it is also a dimension table).

• How to adjust column widths individual classic SQL report

  Hello

  I use Oracle APEX v4.2 with IE8 browser and basically tries to adjust widths of individual columns in my classic SQL report. Basically, I have three columns I want to spacing, so that the width of the entire region for the report is used, but am not sure how to proceed.

  I drilled in individual columns and specified the column widths as the element, but in vain.

  Would appreciate help on how to do this for each column and hope that I do not need to change the model of report (if possible).

  Thank you.

  There is an element of uncertainty in what we suggest as well, because you have not specified the theme and the report of model that is used. This information is required for any question of formatting or the visual layout.

  I drilled in individual columns and specified the column widths as the element, but in vain.

  Report in some themes templates may be missing in the #COLUMN_WIDTH substitution string # required for use of the declarative column widths, as shown here: Re: width of column in reports

  I don't know why it would be missing from a theme of so-called "modern" (perhaps the lack of documentation affects even the Oracle theme designers), but you can add it to the models listed in this thread.

  Width of the element applies only to controls on a form in a table.

  Would appreciate help on how to do this for each column and hope that I do not need to change the model of report (if possible).

  This can be done using selectors CSS attribute (for the themes of quirks mode non-traditional, because you are using a legacy version of IE). Add a style sheet in CSS Inline property page:

  #ALIAS,
  td[headers="ALIAS"] {
  width: 40%;
  }
  

  where the ALIAS value in the attribute selector matches the required column alias, and the width property specifies the column dimension required and the units.

  Note that the percentage widths will be compared to the width of the report table. Therefore, it may be necessary to also specify widths (100%) for the table of report and its components. Exactly how is based on the report, the region and the page templates and theme used, information that was not provided.

  Hello

  I implemented a small suitcase of test on apex.oracle.com and I get the error even if I use the download format.

  I have a table
  test_blob (identification number, name varchar2 (10), blobcont blob)

  If I create IR as

    select
      id,
      name,
      blobcont
    from test_blob
  

  and then I set the download format I got the error.

  If you want this to work you need to change your query to

    select
      id,
      name,
      dbms_lob.getlength(blobcont) blobcont
    from test_blob
  

  And there still define download for blob on column blobcont format.
