Group by behaviour on order of selected row

When using a GROUP BY clause with one or more columns, will the results be in the sorted order of GROUP BY columns (by default) or shall we use ORDER BY clause?

"Oracle use the sort algorythm he wants. He can ascending-sort, descending-sort, hash-sort, or any other internal algorythm."
"You may get lucky and find that your result set is sorted in the order of the GROUP BY columns, but we recommend always using the ORDER BY clause whenever sorting is required."

Selected rows appear in random order when selected from ADF Table

Hi All,
I am working in ADF 10.1.3
I have a ADF Table with a multi select option associated with a DataBean, My requirement is when I select multiple rows from the table and click on some button to goto next page, the selected rows are not getting populated as per the selection order.
Example: If I select 1st,3rd,5th,7th,9th rows from the ADF Table then in the next page I see the results as 3rd,1st,5th,9th,7th. - Randomly it is getting displayed.
I am using the following code to get the records from Multi select ADF Table.
I am adding the selected records to a List.
selectedRowSet = this.getTable1().getSelectionState().getKeySet();
rowSetIter = selectedRowSet.iterator();
if (selectedRowSet.size() > 0)
Integer index = Integer.parseInt((String) rowSetIter.next());
Object rowData = this.getTable1().getRowData(index.intValue());
The order is getting jumbled when I see the final list.
Pls help me in this.
Thanks

Hi Frank,
Thanks for the update.
We are using 10.1.3.3 and already our application in QA Testing. User need this to be fixed. Is there any work around for this problem?
Thanks

Oracle 8i vs Oracle 9/10: Group by and order of returned rows

Hello people,
I've searched the forum for threads on this topic: the order of returned rows in queries which have a GROUP BY clause, and found out that Oracle states that GROUP BY clause does not guarantee that the order of returned rows will be the same every time nor the rows will be ordered someway. I've confirmed this information in the Oracle documentation for the GROUP BY clause for Oracle 9 and 10. But I couldn't find the same in the Oracle 8 documentation (SQL Reference), in which the GROUP BY clause section does not mention anything about the order of returned rows in queries which have a GROUP BY (except for something about using a GROUP BY and a HAVING clause together, which is not helpful in this situation).
Besides, I have an Oracle training book: "Introduction to Oracle: SQL and PL/SQL" for Oracle 8, where the GROUP BY clause is said to perform a default ordering, here is the text:
"By default, rows are sorted by ascending order of the columns included in the GROUP BY list. You can override this by using the ORDER BY clause".
So, I need to find out if Oracle 8 GROUP BY clause did some kind of sorting over the returned rows as it is said in the training book and if this behavior changed in Oracle 9. And more important: where to look for to find documentation about this change.
Thank you, guys, I really hope someone could help me with this.
Fer.

And this statement from Tom (taken from the link above) says more about why the sort (even when done because of group by) should not be relied upon:
<quote from="asktom link above">
and even when it does sort as a by product of its processing, the sort is a
BINARY SORT, not your sort (with your language and character set)
</quote>

To select particular rows from order by select query

Hi all,
I want to select particular rows from a order by select query like...
select * from emp order by ename;
If i pass 3 and 7 dynamically in where clause or something like that, it has to show rows from 3 to 7 only.
Thanks in advance
Pal

This?

   select e.*,
      row_number() over (order by ename) rn
   from emp e)

How to show employee names in descending order but 3rd row is fixed and always top on the table ?

how to show employee names in descending order but 3rd row is fixed and always top on the table ?
for example employee names is A,B,C, D, E
and output is C,E,D,B,A

Since you are posting in the design forum, the short answer is - you don't. Rows in a table have no inherent order that you can rely on and the "position" of rows is a visual characteristic that should be implemented by the application that displays
this information or by the query that is used to generate the resultset.
So the next question is how one accomplishes this particular order within a select statement. That is a tsql question which, for future reference, is best posted to the tsql forum. In addition, many of the questions or issues that you will face
have been discussed in the forums - often many, many times. The first thing you should do when faced with an issue is to simply search the forums and leverage the the knowledge that has already been discussed. In doing so you are quite likely to
see suggestions or related issues that you should consider in your search for a solution.
Now, to answer the question - you need to formulate a order by clause that forces the rows to be sorted in the manner you desire. Effectively you have 2 levels of sorting. The first level divides your rows into 2 groups. Group 1 consists
of rows where name = E and Group 2 is everything else. Following that you then need to sort the rows in each group by name in descending order. Something like:
order by case name when E then 1 else 2 end, name desc

Problem with ordering in select query.

Hi,
We have the following query:
SELECT s.surveyid, m.messageid, m.text FROM MS_SURVEY s, MS_MESSAGES m where (m.messageid=s.survey_desc or m.messageid=s.survey_heading or m.messageid=s.user_profiles) and s.surveyid=xxx
This query selects 3 rows, one for description, one for heading and one for user profiles.
The problem is that, we have 4 databases. 2 Oracle 8.1.5, one Oracle 8.1.6 and one 8.1.7
This query when run on 8.1.7 and 8.1.5 will give us the result in the order:
1...description
2...heading
3...user profile
But, when run on 8.1.6 (which is the client setup of oracle)
The result is in the order:
1...user profile
2...heading
3...description
This project has still not been delivered because of this problem and we are already late by 2 months.
Please somebody let me know why this is happening?
I cannot change the code...as it has been tested for 1 month on staging setup, where it is working fine.
I have no clue as to why this is happening on the Client setup ONLY.
Is it a problem of different oracle versions, or any client side db trigger is there, or any options which the client has selected during his/her db installation or whatever...?
Kindly help.
Thank you.
Regards,

Your query has no ORDER BY clause. Oracle does not guarantee (nor does any other RDB that I know of) to return rows in any particular order in the absence of an ORDER BY.
There are many factors that could affect the order in which rows will be returned in the absence of an eplicit ORDER BY clause. Among these are things like order of insertion of rows, access path chosen by the optimizer, the shoe size of the requestor.
You are going to have to change your code if you want a guaranteed order of the records.

How to deselect the selected row when we come back again?

Hi all,
I have one screen(100),which contains records.User can select any one record and click 'Details' button.Then it will take to screen 110.When I am coming back to screen 110 again.The previously selected row is again in selected mode only.Now if I am selecting another row and click the 'Detail' button.I am getting the error saying that 'Please select one record'.In debugging mode also I checked using the FM get_current_cell but nothing is getting selected surprisingly.

Hello Balaji
The sample report <b>ZUS_SDN_TWO_ALV_GRIDS_7</b> shows basically what I meant in my previous answer. There is no row mark available on the first ALV list. Instead of bothering the user to push a button he or she can simply double-click on the ALV lists and sees the details of a customer.
As you can see there is absolutely no need to free any object instances or rebuild grid controls.
Final remark: based on the function module you mention I assume you are still using fm-based ALV lists. Do not use them. OO-based ALV lists are much easier to develop, to maintain and to enhance.

How to directly access a SELECTED row in a table using MasterColumn

I'm using a table with MasterColumn (TreeByNestingTableColumn) contains checkbox element.
In order to get the selected row I have to navigate the whole tree which is a very expensive when the tree is big.
I also tried without check box by just using MULTI ROW SELECTION property of the table but that didn't work.
Is there a way to directly access selected row like we do in the standrard table control?
Any help would be appretiated.

How to get column value of a selected row of ALV

Hello ,
I have application POWL POWL_UI_COMP uses another component POWL_TABLE_COMP.
This POWL_TABLE_COMP uses SALV_WD_TABLE.
I want to select value of ORDER id and it need to be passed whenever user selects a display order button(Which is self defined function generated in POWL_TABLE_COMP) . I am calling a display order on action of this display button(http://nap60.nalco.one.net:8042/sap/bc/webdynpro/sap/mt_order_app?IV_ACTIVITYTYPE=A&IV_EQUIPMENT=aaaa&IV_ORDERID=90001511&IV_ORDERTYPE=STD&IV_QMNUM=00&IV_TPLNR=00)
ORDERID is one column value of selected row of ALV table.
So please can you suggest , how to read ORDERID and pass it to the self defined function..
thanks in advance,
Sharada

Editing Cell Column of a selected row in UI table element.

Hi Experts,
I have a UI Table Element with three columns. First two columns are input fields in read only mode. Third column is a text edit field.
Now when I Select a row and press a button 'EDIT' i want that particular rows third column CELL alone to be in editable mode.
In order to achieve this, I created a WDY_BOOLEAN attribute in the same node which is used to bind the table. I binded this attribute to the READ ONLY property of third column.
In the EDIT button i wrote the following code.
lo_el_n_stp->set_attribute(
EXPORTING
name = 'A_EDIT'
value = ' ' ).
Here A_EDIT is the name of the attribute.
When i do this, my first rows third column is only going to EDIT mode and not the row which i selected.
Please tell me how to solve this problem.
Thanks in advance.

Hi thanks for your reply.I have already tried this, the problem is i am not getting the seleted row value by using the below code
l
lo_nd_node1->get_static_attributes(
IMPORTING
static_attributes = ). "here you will get the selected row
Its giving me the first row value.

A selected row in af:table does not get sorted.

Hi,
When a table supports single selection and the table contains quantity of rows gt it can fit into its viewport, then, on sorting, selected row gets out of the sorting process. But when you move to the end of the table, select a row there and then sort the table, then all rows sorted correctly. The selected row, after sorting, always set as a first row in the current viewport, doesn't matter whether it is in the order or out of it.
Noteworthy, when number of rows is lt the viewport allows:
1. sorting works as it should to;
2. on sorting/PPR'ing, as it gets some time, one can see how the viewport updates in two steps and in the first step the first row is the selected one.
JDev's version is 11.1.1.3.0.
VO, iterator and tree bindings, af:table all the props related to data retrieving, fetching and row displaying have default values.
What can cause that?
Thx,
Y.

Hi,
so what you are saying is that the selected table row is not sorted but added on top. I tried to reproduce this with 11.1.1.3 but can't see the issue. I tried with editable and read-only tables

Error in receiving tableview data for selected row

Hi Collegues ,
We plan to realize an application for the maintanance of planning data . In the first step we created a value help page by using a tableview with iterator class ( 1 of the 3 methods of the Interface was filled with logic ) . We don't use any controller for that application .
A global internal table with the relevant help value data ( fgrvalues ) is used for the tableview and the call is :
TYPE I .
+CLASS CL_HTMLB_MANAGER DEFINITION LOAD.
CLEAR ONCLICKEVENT.
IF EVENT_ID = CL_HTMLB_MANAGER=>EVENT_ID.
    EVENT_DATA = CL_HTMLB_MANAGER=>GET_EVENT( REQUEST ).
    IF ( EVENT_DATA IS NOT INITIAL ) AND
            ( EVENT_DATA->EVENT_TYPE = 'click' ) .
            ONCLICKEVENT = EVENT_DATA->SERVER_EVENT .
    ENDIF.
ENDIF.+
CASE ONCLICKEVENT.
WHEN 'take' .
   TABLE ?= CL_HTMLB_MANAGER=>GET_DATA( REQUEST = REQUEST
   NAME = 'tableView'
   ID = 'fgr1_vhelp' ) .
   TABLE_EVENT = TABLE->DATA.
   IF TABLE_EVENT->SELECTEDROWINDEX IS NOT INITIAL.
      ROWSELECTION = TABLE_EVENT->SELECTEDROWINDEX.
-> ROWSELECTION - Content is now the index of the selected tableview row
We always get the selected row in TABLE_EVENT->SELECTEDROWINDEX and the table TABLE_EVENT->ALLCOLUMNNAMES filled ( column ZX_FGR1 is the 2nd column )
but we never got the tableview data for that tableview row no matter what we tried . We tried it with a tableview-event fired on 'rowselection' by user line-selection . We have deactivated the iterator or changed the BPS design value . With the same result - nothing was given back .
We found that the System-Call Return value of :
+system-call ict
did
ihttp_scid_get_form_field
parameters
m_c_msg " > c handle
name " > form field name                value " < form field value
                m_last_error. " < return code+
in the method IF_HTTP_ENTITY~GET_FORM_FIELD is empty . M_LAST_ERROR occurs with value '20' .
+ ASSIGN ROWSELECTION TO .
COLUMN_VALUE = TABLE_EVENT->GET_CELL_VALUE( ROW_INDEX =
COLUMN_INDEX = '2' ). -> Column Value is empty !!+
   +CALL METHOD TABLE_EVENT->GET_CELL_VALUE
      EXPORTING
        ROW_INDEX = TABLE_EVENT->SELECTEDROWINDEX
        COLUMN_INDEX = '2'
      RECEIVING
        VALUE = COLUMN_VALUE -> Column Value is empty !!+
   +CALL METHOD TABLE_EVENT->GET_SIMPLE_DATA ....
         -> Column Value is empty !!+ *----
What could be the reason for that problem ? In generally it must be possible somehow to read the tableview data for one or all rows of the mentioned tableview .
We hope that someone can help and are very thankful for a hint or solution . If you need more details please let us know .
Please Remark: It's no solution for us to read the data by using the created internal table fgrvalues and the selectedrowindex cause in a later step we plan to update an ODS table with the manual modified planning data of an editable tableview .
Thanks a lot in advance
Dirk Läufer

Hi collegues ,
It's done .
After we've got a very helpful little hint from Brian :
The <htmlb:tableView> renders a table to the browser. It does not keep a copy of the table. The browser will also never return the table. Never. What it can return are inputfields for each cell. But then only if each cell is custom rendered as an inputfield.
we could certainly solve the problem .
We set the field we want to get back from table view on not editable inputfield via the tableview-iterator method IF_HTMLB_TABLEVIEW_ITERATOR~RENDER_CELL_START :
DATA: LCL_TABLE       TYPE REF TO CL_BSP_BEE_TABLE   ,
      LCL_INPUTFIELD2 TYPE REF TO CL_HTMLB_INPUTFIELD .
CASE P_COLUMN_KEY .
WHEN 'ZX_FGR1'.
*    Field Firm Group
     CREATE OBJECT LCL_INPUTFIELD2.
     LCL_INPUTFIELD2->ID        = P_CELL_ID.
     LCL_INPUTFIELD2->WIDTH     = '100%'.
     LCL_INPUTFIELD2->MAXLENGTH = 4.
     LCL_INPUTFIELD2->TYPE      = 'STRING'.
     LCL_INPUTFIELD2->DESIGN    = 'STANDARD'.
     LCL_INPUTFIELD2->DISABLED = 'TRUE'.
     LCL_INPUTFIELD2->VALUE =
         GET_COLUMN_VALUE( COLUMN_NAME = 'ZX_FGR1').
     P_REPLACEMENT_BEE     = LCL_INPUTFIELD2 .
Now the method in OnInputPorcessing:
TRY.
      CALL METHOD CL_HTMLB_MANAGER=>GET_SIMPLE_DATA
          EXPORTING
            REQUEST       = RUNTIME->SERVER->REQUEST
            ID            = 'fgr1_vhelp'
            ROW_IDX       = TABLE_EVENT->SELECTEDROWINDEX
            COL_NAME      = 'ZX_FGR1'
          CHANGING
            DATA          = FGRVALUES_LINE-ZX_FGR1 .
         IF NOT FGRVALUES_LINE-ZX_FGR1 IS INITIAL.
*                 selektierte Firmengruppe übernehmen
                  ZX_FGR1     = FGRVALUES_LINE-ZX_FGR1   .
                  CALL METHOD NAVIGATION->SET_PARAMETER
                        EXPORTING NAME = 'ZX_FGR1'
                                  VALUE = ZX_FGR1.
         ENDIF.
      CATCH CX_SY_CONVERSION_ERROR .
   ENDTRY.
works properly as it should be ...
An enormous Thanksgiving to you , Brian !!!!

Improving performance:How to know selected rows in af:table through chk box

Hi,
I've a VO which has 3 transient variables. 2 of these transient variables getting the values from a view accessor. Using the other transient variable in the Ui to select the rows in the af:table.
In my UI, I've a table and a Check Box to select the rows. I want to get the selected rows through the check box, in the backing bean for my business requirements.
I've used below logic to get the selected rows. Here, I am iterating through the entire viewobject rows, so it is impacting the performance of the UI. How can I know the selected rows in the bean? or How can I improve the performance?
I also applied below view criteria, but still its not performant.
// ViewCriteria vc = vo.createViewCriteria();
// //.getViewCriteriaManager().getViewCriteria("SelectedMerchantCriteria");
// ViewCriteriaRow vcr = vc.createViewCriteriaRow();
// vc.setCriteriaMode(ViewCriteria.CRITERIA_MODE_CACHE | ViewCriteria.CRITERIA_MODE_QUERY);//MerchantName1
// //vcr.setAttribute("MerchantName1", "1017 CAFE");
// vcr.setAttribute("SelectToMap", "true");
// vc.addRow(vcr);
// vo.applyViewCriteria(vc);
// vo.executeQuery();
public void mapSupplierMerchant2(ActionEvent actionEvent) {
// Add event code here...
OperationBinding method = null;
AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance();
Map pageFlowScope = adfFacesContext.getPageFlowScope();
ArrayList merchantMappingList = new ArrayList();
Long primaryVendorId = null, groupId = null;
CollectionModel tableModel = (CollectionModel) this.getMerchantTable().getValue();
JUCtrlHierBinding tableBinding = (JUCtrlHierBinding) tableModel.getWrappedData();
ViewObject vo = tableBinding.getViewObject();
// ViewCriteria vc = vo.createViewCriteria();
// //.getViewCriteriaManager().getViewCriteria("SelectedMerchantCriteria");
// ViewCriteriaRow vcr = vc.createViewCriteriaRow();
// vc.setCriteriaMode(ViewCriteria.CRITERIA_MODE_CACHE | ViewCriteria.CRITERIA_MODE_QUERY);//MerchantName1
// //vcr.setAttribute("MerchantName1", "1017 CAFE");
// vcr.setAttribute("SelectToMap", "true");
// vc.addRow(vcr);
// vo.applyViewCriteria(vc);
// vo.executeQuery();
List<JUCtrlHierNodeBinding> merchantList = (List<JUCtrlHierNodeBinding>)tableBinding.getChildren();
JUCtrlHierNodeBinding merchantNode = null;
List supToMap = new ArrayList();
boolean isMerchantSelected = false, isMasterSup = false;
Long merchantIdToMap = null, masterSupId = null;
Row r = vo.first();
while(r!=null) {
System.out.println("================================ " + r.getAttribute("MerchantName1") + " " + r.getAttribute("SelectToMap") );
if(r.getAttribute("SelectToMap")!=null) {
isMerchantSelected = (Boolean) r.getAttribute("SelectToMap");
if(isMerchantSelected) {
merchantIdToMap = (Long) r.getAttribute("MerchantMapId");
if(merchantIdToMap!=null) merchantMappingList.add(merchantIdToMap);
r = vo.next();
if(merchantMappingList.size()>0) {
primaryVendorId = (Long) pageFlowScope.get("primaryVendorId");

AdfFacesContext.getCurrentInstance().addPartialTarget(this.getMerchantTable());
tableBinding.getViewObject().setRangeSize(25);
FacesMessage message = new FacesMessage("The selected merchants have been mapped to the group. Please save the changes. " );//+ adfFacesContext.getPageFlowScope().get("merchantGroupName") );
message.setSeverity(FacesMessage.SEVERITY_INFO);

} else {

FacesContext.getCurrentInstance().addMessage(null, message);
}

Hi
Please check this post [http://adfwithejb.blogspot.in/2012/08/hi-i-came-across-one-common-use-case.html].
It has clear explanation of how to provide a checkbox for selection of rows. You can also go through my comments at the end of the post. That should solve your problem of iterating through the entire VO.
Thanks,

How to data from selected row of a TABLE

Hi ,
I have a table displaying some PO order details. In the last column , I have a field with element Link to Action . My requirement is , that when I click on the link to action column of specific row , I want to get the data present( specifically the the data present on the first column which is PO number) i that specific row.
How can i get this data?
Regards
PG

Hi PG,
If you want to get Selected row data, you can use get_selected_elements
Try this example code.. this gives you selected records into one table..
DATA lo_nd_et_postab_1 TYPE REF TO if_wd_context_node.
DATA lo_el_et_postab_1 TYPE REF TO if_wd_context_element.
DATA ls_et_postab_1 TYPE wd_this->Element_et_postab_1.
DATA lt_et_postab_1 TYPE wd_this->Elements_et_postab_1.
DATA: wa_temp TYPE REF TO if_wd_context_element,
        lt_temp TYPE wdr_context_element_set.
navigate from <CONTEXT> to <ET_POSTAB_1> via lead selection
lo_nd_et_postab_1 = wd_context->path_get_node( path = `ZSHP_EXTENDED_DUE_LI.CHANGING_3.ET_POSTAB_1` ).
CALL METHOD lo_nd_et_postab_1->get_selected_elements
    RECEIVING
      set = lt_temp.
LOOP AT lt_temp INTO wa_temp.
    CALL METHOD wa_temp->get_static_attributes
      IMPORTING
        static_attributes = ls_et_postab_1.
    append ls_et_postab_1 to lt_et_postab_1.
    CLEAR ls_et_postab_1.
ENDLOOP.
lo_nd_et_postab_1->bind_table( new_items = lt_et_postab_1 ).
NOW LT_ET_POSTAB_1 Contains selected records in table.
Hope it helps...
Cheers,
Kris.

How do i copy and paste selected rows from numbers to another numbers worksheet

I have asked this question before, but it sounds as if numbers did not have the update at that time. I have pasted a spreadsheet from excel into numbers. I would now like to take selected rows, for example, row 5, row 9, row 22, row 27, etc, copy these entire rows, and pastte into another blank numbers work sheet. In excel, one can hold down the ctrl key, and click on each row they want to copy, and all will be copied in one operation, Than you can paste into a new excel work sheet. I have tried this on my ipad 2 many times, holding down the command key, and tapping on each row I want to copy. I just cannot get this to work. Please let me know how to do this, if numbers even has this possible. Thanks.

I have tried this on my ipad 2 many times, holding down the command key, and tapping on each row I want to copy.
Command Key.... on ipad? Ddint know there was one.
As for copying non-continuous ranges, cannot be done on ipad at this time. On a desktop maybe, but i cannot test it right now.
Each row can be done individually, or you could sort the rows to grab the range you want. To do this (espeically if there is nothing that is unique about them), just make a new column and place a 1 in the cell for each row you want to copy, sort. That will place all your rows together and enable you to copy.paste them back out.
If you want to preserve the original sort order, make another column (I usually use A for this) and put in =ROW() as the equation. Fill it down for the whole table and copy/paste values over it. now after you do any kind of sorting, you can always return the list to the original sort order.
