Select top 10 rows for each product

Hi,
I have to build a query in the following way:
I have a query like,
select dept, product, product_sold
from products
order by 1, 2 desc
But I have a requirement, not to show all the products in dept . I need to show only first 10 rows of each 'dept' column.
Please help me in acheiving this.

You would do something like this (untested):
select dept
, product
, product_sold
from (
   select dept
   , product
   , product_sold
   , row_number() over (
      partition by dept
      order by product
      , product_sold
   ) rn
   from products
where rn <= 10;Assuming that I have correctly guessed the ordering you require...
cheers,
Anthony

Selecting top x rows for each of the groupby clause

Hi Gurus (again).
I have this query to select the top 24 rows:

+) where rownum <=24+
The problem here is that I have a group by "proid" clause in addition to the dates. My purpose is to be able to select the top 24 rows for each of the "proid" that is already grouped by the date. Essentially, the top 24 is the last 24 weeks pertaining to that "proid". How can I do this effectively without creating heaps of UNION clause for each of the "proid"?
thanks in advance

How to select the first row for each pair of values ?

Hi guys, am hoping someone can help me here.
If I have 4 tables - Building, Dept, Emp, Text
B D E T
A 1 Z blah1
A 1 X blah2
A 1 W blah3
A 2 V blah4
A 2 G blah5
A 2 H blah6
B 1 K blah7
B 1 L blah8
B 2 E blah9
B 2 F blah0
I need a query that will bring back the first bit of text for each pair of building and dept records.
So the results I would get would be
A 1 blah1
A 2 blah4
B 1 blah7
B 2 blah9
blah2 wouldnt be returned, because we have already had a record from the Building A, dept 1 pairing.
Likewise we wouldnt get blah5 because we have already had a record from the Building A, dept 2 pairing.
Can this be done in 1 query??
Thanks all.

Hi Pituach, thanks for your reply.
in result Country or grpid should not be repeated... in your result 'GB' and 'US' is repeating.
1) select countries with maximum value of 'Value' for a 'grpid'
2) 'grpid' & country should not be repeated.
3) we need to take next maximum
value if 'grpid' not there a for
highest value.
Result:
Country

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
Cologne, Germany

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 ;-)

XML DB: is it possible to get a row for each element in a container element?

I have an XML document containing a container element (collection). If I query, using an XPath expression, the contained elements I get a row for each container element with the contained element concatenated. Is it possible to get a row for each contained element?
I run this simple query:
select extract(xmltype('<colors><color>Red</color><color>Green</color></colors>')
, '/colors/color/text()').getstringval() from dual
And get this result:
EXTRACT(XMLTYPE('<COLORS><COLOR>RED</COLOR><COLOR>GREEN</COLOR></COLORS>'),'/COL
RedGreen
1 row selected.
What I would like to have is:
Red
Green
2 rows selected.
Wishful thinking or possible? Many thanks!

Sure. This is where our XMLSequence() function comes in. It allows you to treat the top-level nodes in a nodeset as if they were rows in a table when combined with the TABLE() operator. Here's an example.
First, to make the SQL look a little cleaner, I like to define a function like this:
create or replace function testdoc return xmltype as
begin
return xmltype('<colors><color>Red</color><color>Green</color></colors>');
end;.
To break out the nodeset of <color> elements as a table, we use the following query:
select value(list_of_color_elements).extract('*/text()').getStringVal() as color
from TABLE( XMLSequence( extract(testdoc(),'/colors/color'))) list_of_color_elements.
Or, using the new-in-9.2 extractValue() operator so we don't have to remember the text() part:
select extractValue( value(list_of_color_elements), '.') as color
from TABLE( XMLSequence( extract( testdoc() ,'/colors/color'))) list_of_color_elements.
Here the TABLE(XMLSequence(...)) combo produces a table of XMLType, with one XMLType object in each row of the table.
In general, if the XMLType instance were coming from an XMLType table xmltab the query would look like this:
select extractValue( value(colors), '.') as color
from xmltab x, /* Important that this table comes earlier in the FROM clause! */
TABLE( XMLSequence( extract( value(x),'/colors/color'))) colors.
And if the XMLType were instead in a column of XMLType named doc in a table xmltab, then we would have the syntax:
select extractValue( value(colors), '.') as color
from xmltab x, /* Important that this table comes earlier in the FROM clause! */
TABLE( XMLSequence( extract( x.doc ,'/colors/color'))) colorsOnce you get the hang of it, you'll see that the combination of TABLE(XMLSequence()) to "shred" XML nodes into rows, and XMLAgg() to aggregate fragments of XML across multiple rows back into a single document, is quite powerful.

FillBy always fills in the same row in data grid view. How to make it fill in a new row for each click of the Fillby Button? VB 2010 EXPRESS?

Hi there,
I am a beginner in Visual Basic Express 2010. I have a Point of Sale program that uses DataGridView to display records from an external microsoft access
database using the fillby query.
It works, but it repopulates the same row each time, but i want to be able to display multiple records at the same time, a new row should be filled for
each click of the fillby button.
also I want to be able to delete any records if the customer suddenly decides to not buy an item after it has already been entered.
so actually 2 questions here:
1. how to populate a new row for each click of the fillby button
2. how to delete records from data grid view after an item has been entered
Thanks
Vishwas

Hello,
The FillBy method loads data according to what the results are from the SELECT statement, so if there is one row then you get one row in the DataGridView, have two rows then two rows show up.
Some examples
Form load populates our dataset with all data as it was defined with a plain SELECT statement. Button1 loads via a query I created after the fact to filter on a column, the next button adds a new row to the existing data. When adding a new row it is appended
to the current data displayed and the primary key is a negative value but the new key is shown after pressing the save button on the BindingNavigator or there are other ways to get the new key by manually adding the row to the backend table bypassing the Adapter.
The following article with code shows this but does not address adapters.
Conceptually speaking the code in the second code block shows how to get the new key
Public Class Form1
Private Sub StudentsBindingNavigatorSaveItem_Click(
sender As Object, e As EventArgs) Handles StudentsBindingNavigatorSaveItem.Click
Me.Validate()
Me.StudentsBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.MyDataSet)
End Sub
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'MyDataSet.Students' table. You can move, or remove it, as needed.
Me.StudentsTableAdapter.Fill(Me.MyDataSet.Students)
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Me.StudentsTableAdapter.FillBy(Me.MyDataSet.Students, ComboBox1.Text)
End Sub
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Me.MyDataSet.Students.AddStudentsRow("Jane", "Adams", "Female")
End Sub
End Class

Hi,
Let me make sure u r working with table control.
First u have to create a event(VALIDATE) to do the validation.
Inside the event,
1. First get the current index where user has pointed the curson
2. Once u get the index read the internal table with index value.
3. Now u can compare the col1 and col2 values and populate the error message.
1. DATA : lo_elt TYPE REF TO if_wd_context_element,
l_index type i.
lo_elt = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
CALL METHOD LO_ELT->GET_INDEX( RECEIVING MY_INDEX = l_index.
above code should be written inside the event.
Thanks,

How can I have one row for each object?

Post Author: farnaz
CA Forum: WebIntelligence Reporting
I have 3 objcts that one of them is ID and second one is internal code and the third one is quantity.There is more than one value for each ID (becouse of internal code).I want to create a report based on ID and quantity (not based on internal code).I make a break on ID but the result shows me more than one row for each ID.so how can i have just one row for each ID?
another question:
how can I post screen shot of the results to my messag in forum?

Have you tried to omit "internal code" from your grid? In normal circumstances, if you have "ID" and "Quantity" on the grid, then WebI will on its own summarize Quantity based on ID, however, this is provided that Quantity has been set up as a measure (or metric). The quickest way to tell if Quantity is a metric or not is to observe the color of its icon when you look at it in the data panel. If it is a purple (or sometimes appears as pink or fuscia) dot, then it's a measure, but if it is a blue box then it is a dimension. If you need Quantity as a measure then this will have to be modified at the universe (make it look like "sum(Quantity)" in the select phase of the object, and insure the object is defined as a number....

Roles for each Product in Oracle Apps 11i

Hi,
I have one requirement to create role for each product...
For example:
Inventory (INV)... I need to create a role, which will have select privileges on all tables of Inventory...like that for each production, I need to create...
I have one procedure:
(a) create role inv_read_role;
(b) spool the following statement
sql> spool inv_read.lst
sql> select 'grant select on INV.'||object_name||' '||'to INV_READ_ROLE;' from dba_objects where owner='INV' and object_type='TABLE';
sql> spool off
(c) Run the above spool file
Here we are done...
But, If I want to do this for all products in oracle apps 11.5.10.2..
is there any smarter way to do this????? any stored procedure???

I want to give readonly access to AP Tables to one database user or more no of database users.....how can we give...for that , we are going to create seperate role for each module in database..assign that role to database user...then he will be able to select only on that module tables......

Multiple parameters one row for each record

I have this query I want the user to be able to allow the user to enter multiple MATL_CODE_MOD as a parameters, the problem is that the GURMAIL table have multiple records one for each GURMAIL_MATL_CODE_MOD, so it will give me duplicates.. How I can code this, so I can allow the user to enter multiple MATL_CODE_MOD codes, and have only one row for each record...
and GURMAIL_MATL_CODE_MOD in ('8IBC','8IBD')
select
spriden_id,
spbpers_name_suffix   name_suffix,
spbpers_name_prefix   name_prefix,
spriden_last_name     last_name,
spriden_first_name    first_name,
spriden_mi            mi,
srbrecr_term_code,
srbrecr_majr_code,
srbrecr_program_1,
saturn_midd.utlq.f_matl_code_type(srbrecr_pidm)
FROM
saturn.srbrecr,
saturn.spriden,
saturn.spbpers,
SATURN.SPRADDR,
general.gurmail
WHERE
spriden_pidm = srbrecr_pidm
and gurmail_pidm = spriden_pidm
AND spriden_pidm = spraddr_pidm
--and srbrecr_term_code = decode(p_term ,'%',SRBRECR_TERM_CODE,p_term)
and spbpers_pidm = spriden_pidm
and spriden_change_ind is null
--and gurmail_matl_code_mod
and SRBRECR_PROGRAM_1 = 'CMQ'
and GURMAIL_MATL_CODE_MOD in ('8IBC','8IBD')
--AND SPRADDR_ATYP_CODE = 'CM'
AND SPRADDR_STREET_LINE1 IS NOT NULL;

Hi,
SELECT DISTINCT ...will keep duplicate rows out of the result set.
Depending on your data, another possibility might be to not join the table that contains GURMAIL_MATL_CODE_MOD. Do an EXISTS sub-query on that table instead.
If you need more help, post some sample data from all the tables, and the results you want from that data.
Simplify, if possible, You can probably post a problem with 2 or 3 tables, each with 2 or 3 columns, that will have the same answer.
