SELECT COUNT(ApproachId) AS TotalInformationEffectContacts
FROM SourceData
Select * from SourceData Cross join RecordCnt
order by StartDateTime asc
Use GROUP BY datediff(ww,@startdate,@enddate)

How to find total recs in a local table for a particular condition
Hi,
How to find total recs in a local table for a particular condition?
Thanks,
CDWell, you may want to try this as well, and compare to the LOOP way. Not sure what kind of overhead you may get doing this way. Here ITAB is our main internal table, and ITAB_TMP is a copy of it. Again I think there may be some overhead in doing the copy. Next, delete out all records which are the reverse of your condition. Then whatever is left is the rows that you want to count. Then simply do a LINES operator on the internal table, passing the number of lines to LV_COUNT.
data: itab type table of ttab.
data: itab_tmp type table of ttab.
itab_tmp[] = itab[].
delete table itab_tmp where fld1 <> 'A'.
lv_count = lines( itab_tmp ).

How to find active sessions count on a server in weblogic server console
Hi All,
I would like to know how to find active sessions count on a server in weblogic console. I am using weblogic 11g.
Regards,
Sunil.On the deployment, monitoring tab, you can select web applications. Here the number of current sessions are listed per web application deployed on the domain.
The deployment itself (deployments, application, monitoring, sessions) shows a list of sessions and where it is located. Unfortunately, there is no aggregation (but that is something you can so yourself as well).
When you are using a load balancer in front, the count of sessions on per web application on the domain gives you some clue how many sessions there are present on each server.
That is to say, when load balancer is using round-robin (and does that correct), you can take the total number of sessions divide it by the number of servers. -
How to get visible row count in JTable ?
I have one table which is added to one scroll pane. For example my table have total 1000 rows, but at a time only 20 rows should be visible to the scroll pane. And I want to scroll the rows and show only 20 at a time.When user scrolls JTable then next time he can view only 1 to 21, then 2 to 22, and so on. I want to know how to get that number which represents the visible row( in this case it is 20).So kindly help me how to get visible row count. Any help regarding this will be appriciated.
Thanks and Regards,
Sheetalhow to get visible row count.First you need to get the viewport used by the scrollpane. Then you can use methods like getViewPosition() and getViewSize() to get information about the current postition of and size of the viewport.
Then you can use the table method getRowAtPoint(). to determine the first and last visible row which can then be used to calculate the visible row count.
When user scrolls JTable then next time he can view only 1 to 21, then 2 to 22, and so onThis is the default behaviour when a "block" scroll is done.
However when you click on the arrow button on the scrollbar it will only scroll a single row. You could override the getScrollableUnitIncrement() method to return the value from the getScrollableBlockIncrement() method.
However the user can still drag the scrollbar manually which would cause a problem. So you would also need to remove the MouseMotionListeners from the scrollbar to prevent this. -
How to return "Final Row Count" - where I have suppression filters etc
I am building a data interface that outputs "trade records"
Each report/file has a primary header record
each report/file has a secondary header record for EACH TRADE
each report/file has trade details per account under the secondary header record for EACH TRADE
each report/file has a primary footer record, that shows the total row count of the resultant details
the "Records" count in crystal is not what I need, as when the report prints/Exports, certain of those records are suppressed.
I only need what "lands" in my txt file in respect to that final number of total rows of data
Any suggestions are very greatly appreciated. My search thru the forum did not return an answer that I could see.
thank you!
Chris
Edited by: CHRISTOPHER MAINARD on Jul 27, 2010 5:14 PMThank you - I very much appreciate your response - but about the same time you posted - my experimentation and borrowing of like situation formulae seemed to solve it with some tweaking!
first I added this formula to count each "trade record"
Whileprintingrecords;
numbervar linecnt := linecnt +1
then, in the "file footer" added this:
tonumber({@totalRowCount})DistinctCount ({MoxyAllocation.OrderID})1
thank you again for your input, I'm betting I'll find a use for that in the near future.

The best way to do paging and get total rows count given a sql statement
Hi,
Just got a quick question.... what is the best way to do paging as well as the total rows count given by a sql statement.
e.g. "select * from emp"
1. I need to know the total row count for this statement.
2. I also need to do a 10 rows per page....
Is there a way to do it in a SINGLE statement for best performance?
Thanks experts.Sounds more like a "formatting" problem...

Total row count - where from is that value?
Hi,
I need the value of total row count that is displayed at the button of portal report. I need this value to use in my java script.
Is that value somewhere in database? Maybe any variable or hidden form element on the page?
Where from does the portal know when to show only the previous button and when both next and previous? It must by calucated somehow.
Thanks in advance.
best regards
Krzysztof Jungowski
nullThanks. Just to make clear:
Probelm:
I need to display links to pages with part of results at the bottom of page - just like in discussion group: Pages: [1] [2] [3] ....
Solution:
I know that there is a hidden form on every report rendered by portal. In that form there are several elements like:
pagenumer, minrow and maxrows. Updating these elements I can jump to every page with results.
Total row count problem:
The problem is that I don't know the number of pages. If I had a total row count value I would calculate the number of pages and create links only to existing pages.
best regards

3.0.9.8.5 - Total Row Count in reports
"Total Row Count" seems to be broken after applying patch 3.0.9.8.5.
After applying the patch, we viewed an existing report which returned (let's say) 25 rows (and I've got max rows per page set to 5):
The first page correctly says: "Total Row Count in Report- 25" and "Row(s) 1 - 5 "
But then clicking the 'next' button, the following page incorrectly says: "Total Row Count in Report- 10" and "Row(s) 6 - 10 "
So, the total row count is getting screwed up. Clicking "previous" in the example above, the total row count goes down to '5'.
Another 3.0.9.8.5 patch problem appears to be 5 extra <br>'s within the report customize page top level of buttons and the criteria form. Looks ugly.Thanks for the reply.
Is there nothing I can do to fix this problem before the next 3.0.9 patch comes out? We've have perhaps another few months to go before we make the move to portal release 2.
This one issue with patch 3.0.9.8.5 is mostly definitely a show-stopper for us...we cannot live with customers seeing errors as basic as "total rows" returned in queries....we will have to roll back to our previous patch level 3.0.9.8.3. By doing this, we will continue to get bad customer feedback because of the awful performance introduced by that patch (Internet Explorer HTTP 1.0 vs 1.1 / keepalives / SSL issue). That's not to mention that we won't see the benefits of the content-area export/import bug fixes in this latest pathset.
So, if there is ANYTHING we can do to fix this one problem, we (and our customers) would greatly appreciate hearing about it.
thanks,

How to find total memory for Oralce Memory utilization
Hi,
How to find total amount of memory utilized by oracle including SGA+PGA+PROCESS
Thanks,
AbkIs you OS 32-bit ? If you add /3gb in boot.ini , then it will limit oracle.exe to go only upto 3gb.
Add /PAE in the boot.ini and remove /3gb.
then use db_block_buffers parameter instead of db_cache_size
for using db_block_buffers, you need to set another parameter also.
use_indirect_data_buffers=true
db_block_buffers=<number of blocks
db_block_buffers=db_cache_size in kilobytes /db_block_size
(since db_block_size is 8 kllobytes by default in Windows..

How to find total number of records in a BDoc?
Dear all,
I have replicated about BP 1088 records from ISU into CRM system with block size 100. Technically on SMW01, for each successfully processed BDoc, there will be 100 records (corresponds to 100 block size). But due to some failed BDocs, not all "successfully" BDocs will have 100 records each, some may have only 1 record inside...or 30...or 88 for example. So, may i know how to find or is there a report i can look into to find the total number of records clearly shown for each of the successfully processed green status BDocs???
Please help and points will be rewards!!
Thank You
Best Regards,
CKI am just showing this to show how to get the rowcount along with the cursor, if the program has so much gap of between verifying the count(*) and opening the cursor.
Justin actually covered this, he said, oracle has to spend some resources to build this functionality. As it is not most often required, it does not makes much sence to see it as a built-in feature. However, if we must see the rowcount when we open the cursor, here is a way, but it is little bit expensive.

How to get the row count of a Table DATA?
Hi,
In my Adobe form layout, I have a Table node which is bound to an internal table. Now at runtime, I want to determine the number of rows that the internal table has, i.e the row count of the DATA node of the Table. How will I be able to determine the no. of rows of the internal table at runtime using Javascript? I am not being able to find any suitable answer in this forum. Please suggest. Thanks in advance.Hi,
If you bind the interactive form table to the internal table and specify some properties, the table will vary its row size according to the number of data available in the internal table.
You have to wrap the table in a sub form, check 'allow page break with contents' and property 'flowed'.
the table will automatically increase its row size...
Is this the reason for which you wanted for the row count..?
If so, this will help you..
Regards.
