thanks...
remember JSP - total record count for mySQL

hello mr.
i don't want ur suggestion ok
i know that site.
no need to give suggestion if u don't give code.
its better to give proper reply instead of making a
comment in forum.
next time take care
He was perfectly justified in that remark. I have given you the information you need, nicely, twice. But I, and noone else here is going to do your work for you. We will point you in the direction you need to be looking, but we are not going to give code. If you attempt to code something yourself, and it doesn't work, then post the code you tried, and we may make some corrections to it. Then again, with the attitude you've shown so far we probably will not. But one thing no one here will do, is do your work. Especially not for free.
Now, if you are not willing to sit down, and look at the suggestion that has already been made, and attempt to use it. Then continue wasting your time, but go away and stop wasting our time.

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

I 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.

Count total number of record of table with deletion from archiving object

Does anyone know is there any SAP standard program to count the total number of record of the table with deletion from Archiving Object and display in repprt?

Not sure of the question. Are you looking to get the sql "select count(*) from table" from using the TopLink expression framework or are you getting that SQL already and want something else?
If you are looking just to get the count from a table/class, you can use a ReportQuery:
ReportQuery rquery = new ReportQuery(ClassToQueryOn.class);
rquery.addCount(); //equivalent to count(*);
session.executeQuery(rquery);
You can use a report query to return data instead of objects, and use selection criteria just like a normal read query.

How to Count total number of Words in PDF?

I am used Adobe Acrobat javascript inbuilt function getPageNumWords(<pagenumber>) it return the number of words present in specified page, but while am copy and paste text content from PDF file to MS Word, Words count given by MS Word is little bit differ, so any one know in which aspect Acrobat count the words?
Which words count result is correct?
Shall is go with Acrobat Words count result or MS Words count result?
But I want to count the total number of words in PDF file (my input is PDF file) else can I go with iText?
Words count in PDf using iText is possible?

Word counts are likely to vary a little according to how you count. For instance, are hyphenated words one or two words? What if the hyphen is at the end of a line? Do numbers count as words? Headers and footers? Captions?
Generally, you just accept a slight variation. If you are counting words in a professional context, i.e. where payment is per word, you probably need a contractual definition of how words are to be counted; in the absence of one, I suggest you use Word.

Hw to find total number of records

Hi All,
Can anyone help from these
1. how to find total number of reports for a particular cube/ods... need step - step solution
2. how to find total number of records for a particular Cube and ODS and Aggr's to till date.
3.what is sandbox,mirror sys,instance of a sys..?
4.what r TWS(Tivoli Workload Scheduler) jobs? how these r different to standard schedulers?
Thanks in ADv
Linda

Hello Linda,
As you have lots of answers on first 2 so i'll start from 3rd onward.
3. Sandbox is mostly practice system where you can do all kind of R&D, mirror sys can be mirror image of any system depends on the organization and instance of system is again mirror image of one system.
4. TWS is third party tool for scheduling which doesn't come along with SAP like standard scheduler as TWS has been prepared specially for this purpose so it has some more features than standard.
Hope it helps.

How do I count the number of records returned in the CMIS query

How do I count the number of records returned in the query CMIS?
SELECT COUNT(*) FROM ora:t:IDC:GlobalProfile WHERE ora:p:xRegionDefinition = \'RD_PROJETOS_EXCLUSIVOS\''}
Euler Homero

Hi Euler,
interestingly enough, the reference guide for CMIS ( http://wiki.alfresco.com/wiki/CMIS_Query_Language ) that I found does not mention the COUNT function at all. On the other hand it states that: "The SELECT clause identifies which virtual columns to return in the result set. It can be either a comma-separated list of one or more queryNames of properties that are defined by queryable object types or * for all virtual columns."
There are, however, some other posts like e.g. http://alfrescoshare.wordpress.com/2010/01/20/count-the-total-number-of-documents-in-alfresco-using-sql/ which state that they could make it working.
Having asked in the WebCenter Portal forum, I assume that your content repository is WebCenter Content. The CMIS doc for the Content is available here: http://docs.oracle.com/cd/E23943_01/doc.1111/e15813.pdf (no COUNT there either). It does, however, mention explicitly that "CMIS queries return a Result Set where each Entry object will contain only the properties that were specified in the query.". This means your could rather investigate the Result Set. Note that there are also other means than CMIS how to get the requested result set (e.g. calling a search service directly via so-called RIDC).
In the given context I am also interested what your use case is. OOTB CMIS in WebCenter Portal is used, for instance, in Content Presenter, where it is content rather than "parameters" what's displayed.

How to get total number of result count for particular key on cluster

Hi-
My application requirement is client side require only limited number of data for 'Search Key' form total records found in cluster. Also i need 'total number of result count' for that key present on the custer.
To get subset of record i'm using IndexAwarefilter and returning only limited set each individual node. though i get total number of records present on the individual node, it is not possible to return this count to client form IndexAwarefilter (filter return only Binary set).
Is there anyway i can get this number (total result size) on client side without returning whole chunk of data?
Thanks in advance.

Hi,
Thanks for suggesting a soultion, it works well.
But apart from the count (cardinality), the client also expects the actual results. In this case, it seems that the filter will be executed twice (once for counting, then once again for generating actual resultset)
Actually, we need to perform the paging. In order to achieve paging in efficient manner we need that filter returns only the PAGESIZE records and it also returns the total 'count' that meets the criteria.
If you want to do paging, you can use the LimitFilter class.
If you want to have paging AND total number of results, then at the moment you have to use two passes if you want to use out-of-the-box features because LimitFilter does not return the total number of results (which by the way may change between two page retrieval).
What we currently do is, the filter puts the total count in a static variable and but returns only the first N records. The aggregator then clubs these info into a single list and returns to the client. (The List returned by aggregator contains a special entry representing the count).
This is not really a good idea because if you have more than one user doing this operation then you will have problems storing more than one values in a single static variable and you used a cache service with a thread-pool (thread-count set to larger than one).
We assume that the aggregator will execute immediately after the filter on the same node, this way aggregator will always read the count set by the filter.
You can't assume this if you have multiple client threads doing the same kind of filtering operation and you have a thread-pool configured for the cache service.
Please tell us if our approach will always work, and whether it will be efficient as compared to using Count class which requires executing filter twice.
No it won't if you used a thread-pool. Also, it might happen that Coherence will execute the filtering and the aggregation from the same client thread multiple times on the same node if some partitions were newly moved to the node which already executed the filtering+aggregation once. I don't know anything which would even prevent this being executed on a separate thread concurrently.
The following solution may be working, but I can't fully recommend it as it may leak memory depending on how exactly the filtering and aggregation is implemented (if it is possible that a filtering pass is done but the corresponding aggregation is not executed on the node because of some partitions moved away).
At sending the cache.aggregate(Filter, EntryAggregator) call you should specify a unique key for each such filtering operation to both the filter and the aggregator.
On the storage node you should have a static HashMap.
The filter should do the following two steps while being synchronized on the HashMap.
1. Ensure that a ConcurrentLinkedQueue object exists in a HashMap keyed by that unique key, and
2. Enqueue the total number count you want to pass to the aggregator into that queue.
The parallel aggregator should do the following two steps while being synchronized on the HashMap.
1. Dequeue a single element from the queue, and return it as a partial total count.
2. If the queue is now empty, then remove it from the HashMap.
The parallel aggregator should return the popped number as a partial total count as part of the partial result.
The client side of the parallel aware aggregator should sum the total counts in the partial result.
Since the enqueueing and dequeueing may be interleaved from multiple threads, it may be possible that the partial total count returned in a result does not correspond to the data in the partial result, so you should not base anything on that assumption.
Once again, that approach may leak memory based on how Coherence is internally implemented, so I can't recommend this approach but it may work.
Another thought is that since returning entire cached values from an aggregation is more expensive than filtering (you have to deserialize and reserialize objects), you may still be better off by running a separate count and filter pass from the client, since for that you may not need to deserialize entries at all, so the cost on the server may be lower.

SQ02 InfoSet Get Count of Total Number of Records that will be processed

I am developing a query (SQ01) and am currently working on building an InfoSet (SQ02).
The Infoset was set up using a 'Direct read of table'. Next, I'm adding some various fields and then going to Extras and trying to define some code to get the total number of records that my query will be processing. I'm not sure if SAP pulls a filtered result set into a temporary table (by default - if so how could I reference it?) that I can reference or is just pulling in a row at a time in the record processing code, but my question is in regards to getting a record count of how many records are returned in my result set PRIOR TO going through all of the records.
Overall, I'd like to be able to have a field that says Record X of Y. I can get the X part for each line, but cannot get 'Y' until the very end. Any help or ideas would be much appreciated. I've looked around a bunch, but haven't found anything like what I'm requesting.
Query Output would look something like:
Record X1 of Y | Title1 | Amount1
Record X2 of Y | Title2 | Amount2

Hi Subin,
     I have tossed around this idea in my head, but am trying to figure out how to get the values and selection options from the query screen to incorporate into my Select statement within my infoset. The problem I'm running into is that my user enters a group of account numbers and an ending date that has to be pulled from the SQ01 query screen to the SQ02 infoset code. I've looked around for examples on pulling the data from the query screen, but have been unsuccessful thus far. Say for instance I have 15 specific accounts that the user is entering in and they want any records that have been submitted prior to the end of the current month and the start of the business year.
     On my query screen they would enter in something like
Business Year: 2011
Reporting End Date: <= 31.03.2011 (Which equates to all records between 01.01.2011 AND 31.03.2011)
Account #s: 0000, 0001, 0003, 0005, ..., 9999 (These are a variable amount of accounts entered and could include options such as not equal to or even between ranges etc)
In my START-OF-SELECTION code I would need a select like:
NOTE: This is just a pseudo code format, not checked for syntax here
SELECT count(*)
FROM TABLE
WHERE BusinessYear = '2011' AND
    RecordDate Between 01.01.2011 AND 31.03.2011 AND
    Accounts IN (0000, 0001, 0003, 0005, ..., 9999).
So In this select I need to reference the values in the SQ01. How would I reference the account #'s and whether or not the user has entered an account number and said Not Equal on it etc. This select statement would have to be built on the fly, since it's not guaranteed to be the same for each run.
Thanks,
Mark

Count the number of records

Hi all,
I have a BEx report that displays a list of empnos and their details based on a selection. Now I want to count the number of recrods that were selected and display the total number of records that were selected. How can this be done?
Thanks,
Sam

Dear all,
Thanks for the suggestions. Actially I had solved it in another way.
As suggested by Sharma, I had used a CKF as count, But i did not want the empnos to come as the rows with 1 displayed across each row.
I was trying to bring a summary in there.
So I had created a structure in Rows and in the structure created a new selection and in that selection included Employee.
This solved the problem that I was facing.
Thanks everyone for your time and effort!!
Cheers,
Sam

Count the number of records between two key values (BTREE)

How can I count the number of keys between two values?
I'm using python driver, and BTREE access method.
====>
ideally what I want is to average a whole time-series data set (the intervals can change) to a given number of points. The keys are the time stamps and the values are the data that needs to be averaged. I need to count the number of records between two time stamps so that I can divide that number by the number of points i need, and average the data. What is the best way to do this? Or should I just keep the intervals for the time stamp constant and use RECNO access method?
Thank you
(first post btw.. and why aren't there many people in stackoverflow who answer Berkeley DB questions?)

BDB is an embedded db and it does not have any internal counters or statistics that you could grap to use for this. You will need to do it manually.
You can create a cursor, grap the records you want, each time you get the next record you bump a counter.
If you are using RECNO, you can use a cursor to get the record number of the record (DB_GET_RECNO), and if all you data is in
sequentail records with no missing records you can figure out the total count by take last rec # - initial rec # + 1 to get a total count.
If you switch over to the SQL API, you can issue a SQL query to give you a count. Select count(*) Where .......
Since you have to grab the data anyway, then best may be to count records as you go along.
thanks

How to find the number of records per months in cube

Hi,
how to find the number of records per months for my all cubes?
Can i use the ListCube transaction to find totl number f records per cube monthwise ?
Jimmy

Hi,
Here is a program to generate no of records and list of ODS and Cubes in Active version.Schedule this program in background and create a cube to load this information and schedule to the data from the file generated by the program. Schedule this all per you requirement.
1.Copy the code into your Z<programname> from Se38.
2.change the FILENAME in CALL FUNCTION 'GUI_DOWNLOAD' in the program to the location from where you can pick the information to load data to cube(eg Application server).
3.Save program.
4.Schedule the program in background as required
5.Create cube with infoobjects to hold no of records and Infoprovider name
6.Load this cube based on event after the program job is done.
Hence you can report on this cube to see no of records in CUBE or ODS in your box.
Please find the code below.

How to find the number of records in ods?

how to find the number of records in ods?
Pls suggest the solution apart going to the table of ods and seeing the number of records.
Is there any program or function module to see the number of records in ods?
For eg: SAP_INFOCUBE_DESIGNS is a program which gives the detail (number of records) of infocube.

Hi,
I was looking at this and found the following tables that may be of help.
One of these tables will include a summary of the record count of all the tables in your system based on the last time each table had it's database statistics calculated:
DBSTATTADA
DBSTATTDB2
DBSTATTDB4
DBSTATTDB6
DBSTATTINF
DBSTATTMSS
DBSTATTORA
We run on an Oracle database so the table record counts can be taken from DBSTATTORA. Type in AZ in table selection field in SE16 to restrict the output to ODS (or DSO) tables only.
The record count is at the time indicated in the timestamp field. Obviously this is not real time but should not be too out of date - if it is you may be having performance issues and should get your DBA / Basis to run a full refresh of DB stats.
Hope this helps, alhtough not real time the table should give you a decent indication of the size of all your ODS objects (or any other table for that matter!)
