How to get count of rows for a table?

Hi,
How to get count of rows for a table and secondly, how can i have access to a particular cell in a table?
Regards,
Devashish

Hi Devashish,
WdContext.node<Your_node_name>().size() will give you the no: of rows.
This should be the node that is bound to the table's datasource property.
WdContext.node<Your_node_name>().get<node_name>ElementAt(index_value); will select the row at that particular index.
You can access an attribute of a particular row as
WdContext.node<Your_node_name>().get<node_name>ElementAt(index_value).get<attribute_name>();
Hope this helps,
Best Regards,
Nibu.

How to get count as 0 for records not in table

Hi All,
I have requirement where I need count of records in the table based on ids. Example query below
SELECT empid ,
nvl(COUNT(id), 0) empcount
FROM employee
WHERE empid IN(1, 2, 4, 5)
GROUP BY empid
In the table only record for "empid=2" is present so I get count 1 for it. But with it I should get count as 0 for non existing records. Expecting below output
empid | empcount
1 | 0
2 | 1
4 | 0
5 | 0
Appreciate your help and Thanks in advance.
Regards.
Ashish

e.g.
SQL> select column_value deptno, count (deptno)
from emp, table (sys.odcinumberlist (10, 20, 100))
where deptno(+) = column_value
group by column_value
    DEPTNO COUNT(DEPTNO)
        10             3
        20             5
       100             0

How to get all minimum values for a table of unique records?

I need to get the list of minimum value records for a table which has the below structure and data
create table emp (name varchar2(50),org varchar2(50),desig varchar2(50),salary number(10),year number(10));
insert into emp (name,org,desig,salary,year) values ('emp1','org1','mgr',3000,2005);
insert into emp (name,org,desig,salary,year) values ('emp1','org1','mgr',4000,2007);

emp1     org1     mgr     7000     2007Please help me with this..

Frank,
Can I write the query like this in case of duplicates?
Definitely there would have been a better way than the query I've written.

OBIEE - How to get count of members for a level?

I have a dimension logical table and hierarchy defined in my BMM layer. I want to define a logical column that can get distinct count of members at Level0.
Level2
Level1
Level0
I tried creating a logical column using Level0 key and Count Distinct aggregation function in my dimension table. But when I use this column in the report, it gives navigation space error.
Any ideas/thoughts on how to achieve this?
Thanks in advance

Aggregations always work on columns in a logical fact table and never on a logical dimension
- Create a logical fact table based on the same physical table
- Create a logical join between the newly created fact table and the dimension table whose levels we want to count
- Create the Count Distinct columns, one each based on the level key columns
- Expose the columns to the presentation
- Deploy the rpd and it works like a charm

How to define 'First Vsible row' for Tree table in Web Dynpro

Hi,
I am using a table with a treebykeytablecolumn. The user can change the selected
line from another view and then I change the selected line within the tree according to his choice. This works fine.
Unfortunatelly, I did not succeed to change the displayed page in the tree, so the user has to scroll up or down to see the selected data, if it is not on the current page.
I try to bind the 'FirstVisibleRow', using the index of the selected element, but this
index does not fit. The page changes, but as the index is somehow 'wrong', it is not
the expected page that is shown.
Looping at the node, my selected element get index 30, but the selected line is the 8th one (regarding what is current ly open or not in the tree) and the 14th if we expand all nodes above.
So, is there a way to specify which line to be the 1st visible one when there is a tree column?
thanks a lot for your help.
reagrds,
barbara

Follow these steps,
1- Create an attribute with char1 in the view context e.g first_vis_row
2- go to the table properties in view and bind the property first_visible_row to this attribute.
3- NOw go to the wddoinit method of the view...
4- read the internal table and find out the index of the row which you want to set as first row. As in ur case you want a specific date in first row. So read the internal table and findout the index.
5- now write this code, say your attribute name is first row inside node flag1...(you can change it for yoru requirement)
DATA lo_nd_flag1 TYPE REF TO if_wd_context_node.
DATA lo_el_flag1 TYPE REF TO if_wd_context_element.
DATA ls_flag1 TYPE wd_this->element_flag1.
DATA lv_first_row LIKE ls_flag1-first_row.
* navigate from <CONTEXT> to <FLAG1> via lead selection
lo_nd_flag1 = wd_context->get_child_node( name = wd_this->wdctx_flag1 ).
* get element via lead selection
lo_el_flag1 = lo_nd_flag1->get_element( ).
* get single attribute
lo_el_flag1->get_attribute(
    EXPORTING
      name = `FIRST_ROW`
    IMPORTING
      value = lv_first_row ).
here change the lv_first_row to the index which you got after raeading the internal table.
suppose it's
lv_first_row = 4.
lo_el_flag1->set_attribute(
    EXPORTING
      name = `FIRST_ROW`
      value = lv_first_row ).
Hope it works.

Get all the rows of the table

Hi,
     In my example I want to get all the rows of the table. The table has 20 rows. The visibleRowCount is set to 7 and firstVisibleRow is set to 3.
     I have created the table as
     var oTable = new sap.ui.table.Table({
           id: "oTable",
           title: "My Table",
           visibleRowCount: 7,
           firstVisibleRow: 3,
           selectionMode: sap.ui.table.SelectionMode.Single
     I tried to get the rows of the table using the below code
     var table = sap.ui.getCore().byId("oTable");
     var rows = table.getRows();     //     Returns only 7 rows
    How to get all the rows of the table when the table is populated with a odata service ?

Hi Vishal,
The table only put in the html file the rows that you define in visiblerowcount (rows control). The method getRows, get this controls, and you only have 7. The table control render automacatically the data in thats rows when you scroll on it.
If that you want is to retrieve the data of the rows, you need catch it from the model:
oTable.getModel().getData();

How to get number of rows return in SELECT query

- How to get number of rows return in SELECT query?
(i use SQL Server 2000 Driver for JDBC and everything are done, i only want to know problems above)
Thanks.

make the result set scroll insensitve, do rs.last(), get the row num, and call rs.beforeFirst(), then you can process the result set like you currently do.
         String sql = "select * from testing";
         PreparedStatement ps =
          con.prepareStatement(sql,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
         ResultSet rs = ps.executeQuery();
         rs.last();
         System.out.println("Row count = " + rs.getRow());
         rs.beforeFirst();~Tim

How to create a new row for a VO based on values from another VO?

Hi, experts.
in jdev 11.1.2.3,
How to create a new row for VO1 based on values from another VO2 in the same page?
and in my use case it's preferable to do this from the UI rather than from business logic layer(EO).
Also I have read Frank Nimphius' following blog,but in his example the source VO and the destination VO are the same.

2.Drag and drop a Createwithparams button for VO1(id,amount,remark),

Hi,CM,
I'm really very appreciated for your quick reply! You know, today is Saturday, it's not a day for everyone at work.
My principal requirement is as follows:
1.select/check some rows from VO2, and for each selection create a new row with some attributes from VO2 as default values for VO1's corresponding attributes, and during this process the user may be cancel/uncheck or redo some of the selections.
--so it's better to implement it in UI rather than in EO.
2.it's better to implement this function with declarative way as in Frank Nimphius' blog.
--little Jave/JS coding, the better. I only have experience in ORACLE FORMS, little experience in JAVA/JS.
In order to get full information for the requirements of my use case, can take a check at:
How to set default value for a VO query bind variable in a jspx page?

How to get Only 20 rows? (Urgent)

Hi, everyone.
If I want to get only 20 words from a table,
how can I write query?
For example,
Table name: WORD (this table is like dictionary)
columns: W_WORD, W_MEANING
Select * FROM WORD
WHERE W_WORD LIKE 'H%'
ORDER BY W_WORD ASC
This query gets all the words starting with 'H'.
But, I want to get only 20 results(rows).
How can I do? I'm using MS Acess.
Please response me. Thank you.

You seem to be using SQLserver.
SELECT TOP 20 *
FROM WORD
WHERE W_WORD LIKE 'H%'
ORDER BY W_WORD ASC
Look up the TOP clause in the docs for further info, other DBMS may have different syntaxes for this functionality

What do you mean by "get" and "transfer"?
If the shift register is not what you want, use a plan tunnel instead.
Typically, programmers are interested in the first, not last, error.

Getting the first row for each group

Hi Everyone,
I have a query which returns a number of rows, all of which are valid. What I need to do is to get the first row for each group and work with those records.
For example ...
client flight startairport destairport stops
A fl123 LGW BKK 2
A fl124 LHR BKK 5
B fl432 LGW XYZ 7
B fl432 MAN ABC 8
.... etc.
I would need to return one row for Client A and one row for Client B (etc.) but find that I can't use the MIN function because it would return the MIN value for each column (i.e. mix up the rows). I also can use the rownum=1 because this would only return one row rather than one row per group (i.e. per client).
I have been investigating and most postings seem to say that it needs a second query to look up the first row for each grouping. This is a solution which would not really be practical because my query is already quite complex and incorporating duplicate subqueries would just make the whole thing much to cumbersome.
So what I really new is a "MIN by group" or a "TOP by group" or a "ROWNUM=1 by group" function.
Can anyone help me with this? I'm sure that there must be a command to handle this.
Regards and any thanks,
Alan Searle

Something like this:
select *
from (
   select table1.*
   row_number() over (partition by col1, col2 order by col3, col4) rn
   from table1
where rn = 1In the "partition by" clause you place what you normally would "group by".
In the "order by" clause you define which will have row_number = 1.
Edit:
PS. The [url http://download.oracle.com/docs/cd/E11882_01/server.112/e17118/functions004.htm#i81407]docs have more examples on using analytical functions ;-)
