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

Thanks. 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

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...

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 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

Thank 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.

How to get row count(*) for each table that matches a pattern

I have the following query that returns all tables that match a pattern (tablename_ and then 4 digits). I also want to return the row counts for these tables.
Currently a single column is returned: tablename. I want to add the column RowCount.
DECLARE @SQLCommand nvarchar(4000)
DECLARE @TableName varchar(128)
SET @TableName = 'ods_TTstat_master' --<<<<<< change this to a table name
SET @SQLCommand = 'SELECT [name] as zhistTables FROM dbo.sysobjects WHERE name like ''%' + @TableName + '%'' and objectproperty(id,N''IsUserTable'')=1 ORDER BY name DESC'
EXEC sp_executesql @SQLCommand

The like operator requires a string operand.
http://msdn.microsoft.com/en-us/library/ms179859.aspx
Example:
DECLARE @Like varchar(50) = '%frame%';
SELECT * FROM Production.Product WHERE Name like @Like;

Query to get rows betwen x and y + table total row count

Hi,
I try get rows between e.g. 100 and 150 when I sort by some column
My query is now like this
SELECT *
FROM
(SELECT a.*,
    row_number() OVER (ORDER BY OWNER ASC) rn,
    COUNT(1) over() mrn
FROM (SELECT * FROM all_objects) a
WHERE ROWNUM BETWEEN least(100,mrn) AND 150It is not very fast if I run that kind select from big table
Any tips to optimize this query?
Regards,
Jari

Hi,
I'm so bad with SQL :(
Here is sample where I need that kind query.
http://actionet.homelinux.net/htmldb/f?p=100:504
It looks standard Apex report but it is not.
It is just test to use query to output html using htp package
I send parameter start row, max rows, column I like order by.
Now I do query for cursor
    /* Report query */
    l_sql := '
      SELECT * FROM(
        SELECT a.*, row_number() OVER (ORDER BY '
        || l_sort_col
        || ' '
        || l_sort_ord
        || ') rn, COUNT(1) over() mrn
        FROM(' || l_sql || ') a
      ) WHERE rn BETWEEN LEAST(' || l_start_row || ',mrn) AND ' || l_last_row
    ;Then I loop cursor and output html.
You can order report by click heading and there is that pagination
I did not know that I could find examples by "pagination query" =), thanks for that tip for both of you.
I know Apex have reports ,
but I need have features that Apex templates can not provide at least yet.
So I have study that generating html tables using custom package instead Apex report should be best approach to get layouts I need.

Count total rows in database?

Hello all,
Is there a way to query the database for the total number of rows.... without using ANALYZE STATISTICS? (That would cause the db to sometimes use COST instead of RULE based optimization, slowing it down significantly.)
I know I could could brute force a total row count with something like:
spool get_total_rows.sql
SELECT 'SELECT COUNT(*) FROM '||owner||'.'||table_name||';'
FROM ALL_TABLES;
spool off
...then run get_total_rows and manually add all the counts.
But it just seems like there must be a cleaner way to do it.
Thanks much,
Natasha

Unique row count in table footer

JDev 11.1.1.6
Hi,
In my current table, I am able to show total row count at a table footer by using #{bindings.<myVO>Iterator.estimatedRowCount}.
I have a request from my user to show unique total row count. For example rows below:
1 A
2 B
3 A
4 C
The footer should show:
4 3
The second column has A, B, and C where A is counted only 1 (unique). Is there a way to achieve this?
Thanks.

Hi RRA,
This may work for a static # of rows (no filtering). In the table I use, I can do filtering and that certainly will make the count result be different if I use another VO for distinct result.
Thanks.

Dynamically Add Report Parameters & Get Row Count

In out Portal reports, we are inserting records into our own logging tables at the beginning of the report and updating the record at the end of the report. Currently, the sequential key has been added as a parameter so that we can access it through-out the report execution. Therefore, it displays on the parameter screen. We don't want the users to see this item. Is it possible to add it to the parameter list without having it display on the screen? Can this be done using a procedure in wwv_standard_util? Any other suggestions?
Also, we need to get the total row count of the query. Where can we get this value?

Working with VERY LARGE tables - is it possible to bypass row counting?

Hello!
For working with large result sets ADF provides the `Range Paging` mechanism for views, described in the 27.1.5 part of the Developer’s Guide For Forms/4GL Developers.
It works well, but as a common mode it counts total row count to allow paging. In some cases query `select count(1) from (SELECT ...)...` can take very, very long time.
But if a view object doesn't know row count (for example we can override getEstimatedRowCount() method ), paging controls doesn't appear in user interface.
Meanwhile I suggest that it's possible to display two paging links - Prev and Next, without knowing row count. Is it a way to do it?
Thank in advance,
Ilya Rodionov.

Hi Ilya,
while you wait for Franks to dig up the right sample you can read this thread:

Estimated row count

hello
i used estimatedrowcount on several occasions in my application to hide and show certain parts of the screen (normally in EL expressions)
why is it called ESTIMATED and not EXACT. Of course, there is a reason why i ask,
sometimes and in certain pages in which i add new row, it is not also the case that the value of EstimatedRowcount is always updated when a new row is inserted. Also what if another use is adding rows through the same page but from a different browser (different instance of the same applications).
In other words, when does the framework issues SELECT count() on the page to reflect an updated SELECT count().
In certain situation , i had to create VO in order to make sure that i control that the count() is specifically calculated when i need since i noticed that the default EstimatedRowCount does not always give the expected result and henceforth, could be unwise to depend on it to control the logic
rgds
ammar sajdi
Amman jordan

You are right, the estimated row count does not query the database every time you call the method. It just is designed to give you the estimated row count in the context of the "current query" of the VO. So, you perform a query. After the query is performed, the table binding, for example, calls the getEstimatedRowCount() method to determine how many rows are to be expected (keep in mind that probably not all rows are fetched at once after the query). Nothing wrong with that. The ViewObject is executed, 20 rows are fetched, the estimated row count tells the binding that there are 100 rows in the result. If then another user inserts a new row, then that typically will have no effect on the 100 rows, meaning you won't get 101 rows at a sudden. If you scroll through the result set, you will get the 100 rows. In order to get 101 rows, you will need to re-execute the query. Then the table binding will get the estimated row count and it will be 101.
As soon as the fetch is complete, meaning that all rows are fetched from the database and are in memory, then getEstimatedRowCount() no longer accesses the database (why should it?!) but just returns the count of fetched rows. Of course, taking into account any unposted rows that you may have created.
If you really want the row count from the database, why don't you just call getQueryHitCount()? Why must it be getEstimatedRowCount()?!

hi folks,
How to get a tables' row count (number of records)?
Values of table are filled by an RFC return structure. Or how can we get the number of records in the RFC return structure?
thanks in advance

Hi,
Check the size of the node bound to the table
lets say orders is the node bound to the table
//Replace orders with the node bound to your table.
