Number of rows returned for a report

I want to create reports on serveral tables, the number of rows in these tables varies a lot (5, 5000, and the other one can have 10000+ rows).
In the Reports Attributes page, is there a way to set the max number of rows return to the number of rows of the table? For example, for a table that has 10000 rows now, may grow to 20000 rows in the near future. If I specify the "Max Row Count" to 20000, the number may be outgrown yet again soon. If I can specify "Max Row Count" to "Current number of rows in the table" then this problem will not happen. Can it be done?

that "Max Row Count" attribute is used to limit the number of rows returned by a htmldb report region. in your case it sounds as if you want to show all available rows all the time. in that case you'd be fine to just put a very large number into that field like 4million. that way you'd always show all your rows.
hope this helps,

  • How to get the number of rows returned by a report?

    Hi,
    I'm developing my first application in APEX and so far everything seems fine, except I can't figure out this very simple thing: I have a report based on a PL/SQL block returning an SQL string. I'd like to have a message (something like "X rows returned") just before the report. The closest thing I could find was "X to Y out of Z" in the pagination styles, but that's not what I want. Also I don't think running the same query to get COUNT() is wise.
    Any help would be appreciated.
    Thanks,
    Konstantin

    My guess is that it only shows the number of rows it has retrieved. I believe the defailt is for it to only retrieve 50 rows and as you page through your report it retrieves more. So this would just tell you how many rows was retireved, but probably not how many rows the report would contain if you pages to the end. Oracle doesn't really have a notion of total number of rows until the whole result set has been materialized.

  • Total Rows returned in interactive report

    Hi
    I have an interactive report that displays a warning message if more than 200 rows are returned. Is there anything within APEX that tells me the exact number of rows returned in my report, or at the very least if my report has exceeded my 200 row limit?
    I have a button on my page that I only want to display if the number of rows returned in my query is <= 200.
    I know that I could use say NDS to execute my select statement in order to determine the number of rows as a seperate statement - but this seems a bit of over-kill.
    Many thanks

    You can change the this from report attributes. Click on Edit page >> click on the Interactive report >> click on Report Attributes on the top >> down the bottom there is an option where you can change the row numbers and error message etc.

  • How to Customize the Message "No Row Returned" from a Report

    Hi,
    I've been trying to customize the Message "No Row Returned" from a Report.
    First i followed the instructions in Note:183131.1 -
    How to Customize the Message "No Row Returned" from a Report
    But of course the OWA_UTIL.REDIRECT_URL in this solution did not work (in a portlet) and i found the metalink document 228620.1 which described how to fix it.
    So i followed the "fix" in the document above and now my output is,..
    "Portlet 38,70711 responded with content-type text/plain when the client was requesting content-type text/html"
    So i search in Metalink for the above and come up with,...
    Bug 3548276 PORTLET X,Y RESPONDED WITH CONTENT-TYPE TEXT/PLAIN INSTEAD OF TEXT/HTML
    And i've read it and read it and read it and read it and can't make heads or tails of what it's saying.
    Every "solution" seems to cause another problem that i have to fix. And all i want to do is customize the Message "No Row Returned" from a Report. Please,...does anyone know how to do this?

  • Including column from fact table reduces number of rows returned

    Hello
    I am facing this issue where in a report I select 5 columns from a fact table. Out of these five columns one of the column is "Amount" for which the aggregation rule is defined as Sum in RPD.
    When I include these five column and filter results based on some criterion , I get all the rows (three rows) that satisfy the criterion. No I add a sixth column to my report and suddenly I only see one row returned by my report. Addition of this sixth column does not affect the criterion as the criterion is not based on this column. But this sixth column is a calculated column.
    I tried different things but because the report was just getting columns from one table (fact) and suddenly inclusion of one column leads to reduction in number of rows , I was unable to find any reason why would that happen.
    So I thought that some one in community may know that in what scenario this happens.
    Thanks

    Are there any repeated values? I'm wondering if what you're seeing is actually suppression of repetition in the results. Edit the analysis, go to the criteria tab, click column properties, go to the Column Format tab, and change the setting for value suppression from 'Suppress" to "Repeat". Repeat for each of your 6 columns and check the outcome.
    Otherwise, I would try testing with other calculations and also bring in some columns from dimension tables to see how this affects the result. You should be able to come up with a case-by-case scenario to work out exactly what causes the rows to be suppressed which will get us one step to closer to working out why the rows get suppressed.
    Thanks,

  • How to get number of rows return in SELECT query

    i'm very new in java, i have a question:
    - How to get number of rows return in SELECT query?
    (i use SQL Server 2000 Driver for JDBC and everything are done, i only want to know problems above)
    Thanks.

    make the result set scroll insensitve, do rs.last(), get the row num, and call rs.beforeFirst(), then you can process the result set like you currently do.
             String sql = "select * from testing";
             PreparedStatement ps =
              con.prepareStatement(sql,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
             ResultSet rs = ps.executeQuery();
             rs.last();
             System.out.println("Row count = " + rs.getRow());
             rs.beforeFirst();~Tim
    NOTE: Ugly, but does the trick.

    TELL ME HOW MANY ROWS YOU HAVE IN TABLE?
    Because you have only *6 rows* in you column, if you less than 10 rows then it displays only containied/exist rows. nothing much
    select ename,empno from emp where rownum < 10;Thanks

  • Limiting number of rows returned by SQVI

    I've created a query in SQVI and I need to limit the number of rows returned by the query.  (I'm using the query as an exploratory tool, and it's not easy to predict how many records will be returned based on the selection fields I'm using.)
    Is there any way to add a 'Maximum No. of Hits' field to the SQVI selection screen similar to what is found when using SE16?
    Thanks,
    Bob

    It's not surprising that you are confused because the documentation doesn't bother to explain what the "fetch size" actually is, it just says that setFetchSize sets it and getFetchSize gets it. As I understand it from some other documents I read about JDBC, the fetch size is a number that may be used internally by the JDBC driver. Here's an example of how I understand it (others, I know you will feel free to correct me if you disagree):
    When the driver produces a result set with a very large number of records, it has to generate those records and deliver them to the system that requested them. If the database is not on the same system, then those records must all travel over the network. It could be a performance problem if you had to wait for (say) 80,000 records to travel across the network. Enter the fetch size. If you set the fetch size to 100, then the driver will bring the records across in batches of 100, as the program calls for them. Now, this buffering is transparent to your program; the driver doesn't tell you that it's getting another batch and you can't tell it to get another batch. So it is not a solution to the problem that everybody has here, namely how to display your records 10 per page and allow the user to go back and forth among those pages, like search engines do.

  • Getting the number of rows returned from ResultSet

    Hi,
    Does anyone know a method to get the number of rows returned with a query using the Resultset class?
    Thanks.

    Hi 281080,
    If your database and JDBC driver support it, in order to use the solution that da-alexj has suggested, you need to create a 'scrollable' "ResultSet" -- the javadoc for method "createStatement()" (in class "java.sql.Connection") has more details.
    However, I have found with Oracle 8.1.7.4 database and Oracle (thin) JDBC driver, that part of their implementation of the "last()" method (in class "java.sql.ResultSet") is to actually iterate through the entire "ResultSet" in order to reach the last row. If your "ResultSet" is very large (I tested it with a 100,000 row "ResultSet"), this will take a long time.
    Just wanted to make you aware of that.
    Of-course, this may be irrelevant to you since I didn't see any mention in your post of what database and JDBC driver you are using.
    Hope this has helped you, anyway.
    Good Luck,
    Avi.

  • How do you limit the number of rows return from query?

    How do you limit the number of rows return from query? Do all databases support this kind of feature?

    i think the standard is limit
    to get the top 30
    select * from mytable LIMIT 30;returns the first 30 rows
    also if you want a range
    select * from mytable LIMIT 10,30;returns 30 rows starting from 10
    this last one is useful for displaying ranges... something similar happens in these forums when viewing topics and messages

  • Number of rows returned in a query

    Is there a way to get the number of rows returned from a query without itterating through the itterator?
    Thanks,
    Yon

    No.
    Because rows are not all returned until you start interating.
    Some times I have seen people do a count query before the normal query, this helps out if you need a count to set things up.
