How can i select some row from multiple row in the same group of data

row , select only one row which Column B = 'NG'
the result i want =

DECLARE @forumTable TABLE (a INT, b CHAR(2))
INSERT INTO @forumTable (a, b)
VALUES
(1, 'OK'),(1, 'NG'),

ON f.a = f2.a

How to efficiently select random rows from a large table ?
Hello,
The following code will select 5 rows out of a random set of rows from the emp (employee) table
select *
from (
select ename, job
from emp
order by dbms_random.value()
where rownum <= 5my concern is that the inner select will cause a table scan in order to assign a random value to each row. This code when used against a large table can be a performance problem.
Is there an efficient way of selecting random rows from a table without having to do a table scan ? (I am new to Oracle, therefore it is possible that I am missing a very simple way to perform this task.)
thank you for your help,
John.

How can I select the workbook belongs to particular AWm
Hi,
How can i find oracle discoverer plus workbook is belongs to which awm/measure folder thru SQL.
I have 2 workbooks namely workbook1,workbook2 .These workbooks created based on 2 different Aw in 2 different users.
When you give the workbook name in a sql how to find this workbook belongs to this awm ??
I can able to find the workbook belongs to which user from BISM_OBJECTS but I couldn't locate the workbook belongs to which Awm/MeasureFolder name.
Any idea??
Thanks,
Natarajan.UHi
Unfortunately, just like with standard Discoverer which stores its workbooks as a binary object inside EUL5_DOCUMENTS, the same applied to the OLAP workbooks. You won't be able to read the inner workings I'm afraid.
Oracle do have a workbook dump utility for the standard Discoverer. You might want to ask Support if they have a similar tool for examining OLAP workbooks.
Best wishes

How can i select the next column instead of next row when press enter key
I need to know how can i select the next column instead of next row when i press the enter key.By default ,when i press enter key the next row is selected and the column remain unchanged but I wants opposite that is the row should remain unchanged but column index will changed.
Thanks to all.Well, the right arrow key will already move you to the next column, so the easiest way to do this is to modify the InputMap to have the Enter key invoke the same Action as the right arrow key.
You can search the forum for my "Table Actions" (without the space) example that will show you how to do this. -

We'll I don't think there's a easy way to delete a lot of emails besides deleting all of them. To delete all of them click on inbox them edit then "mark all" then trash/delete. Other than that you will have to specifically deleted the ones you want to delete.

How can I select the existing worksheet while using OLE2 to open the template workboo
Source:
application:=ole2.create_obj('Excel.Application');
workbooks:=ole2.get_obj_property(application,'Workbooks');
args := ole2.create_arglist;
ole2.add_arg(args, 'c:\RptTemplate.xlt');
workbook:=ole2.invoke_obj(workbooks,'Open',args);
ole2.destroy_arglist(args);
worksheets:=ole2.get_obj_property(application,'Worksheets');
args := ole2.create_arglist;
ole2.add_arg(args, 'Sheet1');
worksheet :=ole2.invoke_obj(worksheets,'Select',args);
ole2.destroy_arglist(args);
Problem:
1. While executing the above code, error -305500 occurs after executing "worksheet := ole2.invoke_obj(worksheets','Select',args)". How can I select the sheet i wanted in the template ??
2. As I refer to the forms on-line document, it stated that the ole2 programmers documentation can provide all object types and methods that can be used with the OLE2. Does any link can provided to download the specified documentation ??The error is probably that your Worksheets variable is actually empty. Looking at your code I think the problem is that you try and get the value of the worksheets collection from the application then you should try and get it from the Workbooks object.

Thanks for the support
HansHi,
I had posted a similar query few days back to place excel file in text frame. And I found out that, it is not possible to specify formatting option for any of microsoft document when using Indesign SDK.
But we can do this by running script.
If you are able to specify the formatting option through script, write code to get script object & execute this script through Indesign SDK.
I was able to specify formatting option, sheet number, range etc through this.
Hope this helps.

How can I view the size of a particular event in iPhoto '11?
How can I view the size of a particular event in iPhoto '11? The 'Get Info' option is not displaying the size of the event like it used to in iPhoto 8.
But the event does not really have a size - you can export the photos and make the size pretty much what you want - while it is in iPhoto it is an event
I guess that iPhoto could report the size of the original photos as imported - or the size of the modified photos if exported as JPEGs - or the size of the modified photos if exported with a maximum dimension of 1080 - but the event simply is photos and does not have a "size" until you export it
Obviously you want to know the size but the question was
what is your puprose for knowing the size?
WIth that information maybe there is a way to get you what you want
But the basic answer is simply that an event does not have a size - an event is a collection of photos and each photo has either two or three versions in the iPhoto library and each photo can be exported for outside use in several formats and at any size

How can I sum the values in a given column on sheet 1 i.e. A1:A50 based on the adjacent columns specific value i.e. B1:B50 = “Dinning Room” on sheet 2
For Example:
SHEET 1
A
B
$50
Dinning Room
$800
Dinning Room
$300
Kitchen
$1,000
Master Bedroom
$100
Dinning Room
SHEET 2
Display the total SUM amount of each Project based on Sheet 1
Project Name
Total Cost
Dinning Room
$950
Kitchen
$300Would be a good idea to open iWork Formulas and Functions User Guide and search for the description of the function named SUMIF
The Guide is available for every user thru the Help menu.

*How can we use the internal table in module pool programming? Clarify plz*
If we creating a screen using the table having four fields(for e.g.). The screen has the functions of display, modify, delete, save, exit etc for the fields. The front-end of the screen having I/O fields of the table using internal table. How can we declare the internal table in the screen?
HI,
Create one WA for your Internal table and then map it to your fields.
For Example,
Data : begin of wa,
name(10),
age type i,
end of wa.
data : it like table of wa with header line.
Then in screen create input fields with the name, age and ***.
Then the user entered values are stored in name age and ***.
then you can manipulate with that values using wa.
Thanks. -
