RDS Query Viewer - Rows Returned Limit

If you run a query within the RDS Query Viewer and the recordset is larger than 50 rows, only the first 50 are displayed. It would be nice to have the option to set the maximum (or have no maximum at all).
I realize there are a variety of database plug-ins and tools as noted on Charlie Arehart's blog. Most of these would get around this cap of 50 rows, but seeing as how we already have some database querying capability within the RDS toolset it would make more sense to just have it all in one place. I even find RDS Query Viewer useful for running other CRUD operations such as UPDATE, DELETE and INSERT.
If for some reason Adobe is feeling the Christmas spirit at this time in the year, then making the recordset grid copy-and-pasteable would be a hot feature to have as well.

Good point, Jose. I'd missed that myself. And I just noticed this limit of only the first 50 was the case for the Adobe Eclipse Extensions for CF8, too.
I guess in that respect I'd say that the fact I'd not noticed it until now in interesting: I've just used the feature to get a sense of what data is typically in a given table and its columns. For that, the first 50 are enough. But sure, if one wanted to browse all the records, being able to skip through would be nice (you could do that in Dreamweaver's RDS-based database viewer, which showed 25 at a time. Interestingly, HomeSite+'s database viewer simply showed all data.)
But sure, it might be nice to see paging through the records in CFBuilder's viewer. I could see how the ability to copy text from the grid can help, too.
And thanks for the mention of my CF411 site, Jose.

Cannot get RDS Query Viewer to work

This appears to be the same or similar problem with RDS Query Viewer that showed up in Ver 2.0.
Right clicking on a table and selecting RDS Query Viewer gives the following error:
Resource '/mydir/.rdsTempFiles/RDS Query Viewer does not exist.
The .rdsTempFiles directory with RDS Query Viewer file are created in mydir. The file is 0 bytes.
Anyone else seeing this?

Query Viewer not working

New install of CFB 2 on Win 7 32bit with CF901.
When right clicking on a database table in RDS Dataview I get an error , I get the error "/MyProject/.rdsTempFiles/RDS Query Viewer does not exist". The same is happening when trying to open the RDS Query Viewer.
This works correctly in CFB 1.
Any suggestions what is going on? Is it a permissions issue or something similar? The .rdsTempFiles directory is created in the /MyProject folder and shows up in the Navigator.
Thanks
Doug

Hi Kiran,
I cannot login to the Forums (the login is apparently down) so will answer what I have found.
Running CFB2 on Win 7 32bit. CFB 1 is also installed.
Tried the following: ( CFB 2 ALWAYS started with -clean option )
1. started with no projects at all in Nav. View.
     Added New Project called "test List" that was pointed to "C:\inetpub\wwwroot\testlist" folder - Query Viewer did not work
2. deleted project from Nav View, deleted .project, .settings., settings.xml, .rdsTempFiles from testlist folder.
     Added New Project called "test List2" that points to same testlist folder. Query Viewer did not work.
     Renamed "test List2" to "testlist". Query Viewer did not work.
3. Deleted project from Nav View, deleted .project, .settings, settings.xml, .rdsTempFIles from testlist folder.
     Restartd CFB2. Added New project called "testlist" that points to same testlist folder. QUERY Viewer worked successfully.)))
     Renamed testlist project to "Test List". Query Viewer worked.
Restarted CFB2 and repeated 1 and 2. Even re-started CFB2 after adding a new project before trying Query Viewer. Did not work.
Uninstalled CFB2. Reinstalled CFB2. Same results as 1,2,3.
Other interesting info.
In the Error Log when I start CFB2, I always get the following.
     Unable to create a template transfer. Com.adobe.rds.core
     Three more entries with No message except "No stack trace" - com.adobe.ide.coldfusion.server
This happens even after my reinstall.
Hope this helps.

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

How can I limit the number of rows returned by a select stat

How can I limit the number of rows returned by a select
statement. I have a query where I return the number of stores
that are located in a given area.. I only want to return the
first twenty-five stores. In some instances there may be over
200 stores in a given location.
I know is SQL 7 that I can set the pagesize to be 25....
Anything similiar in Oracle 8i?

Watch out. ROWNUM is run before ORDER BY so this would only
order the 25 selected

Problem with Top N Query when no rows returned (takes forever)

I have a table with 100 Million rows and I want to get the latest N records using:
SELECT * FROM
(SELECT * FROM tablename WHERE columnA= 'ABC' ORDER BY TIME DESC)
WHERE rownum <= N;
This works fine and is very fast when there are rows with columnA= 'ABC' but when there are no rows with columnA= 'ABC' the query takes forever.
The strange things is that the inner query returns immediately when run on it's own when no rows with columnA= 'ABC' exist e.g.
SELECT * FROM tablename WHERE columnA= 'ABC' ORDER BY TIME DESC
So why does it take for ever for to run:
SELECT * FROM (no rows inner query) WHERE rownum <= N;
I have also tried using:
SELECT * FROM
(SELECT columnA, rank() over(ORDER BY TIME DESC) time_rank
FROM tablename WHERE columnA='ABC')
WHERE time_rank <= N;
which returns instantly when there are now rows but takes much longer than the first query when there are rows.

I cannot see a real difference:With histogram we can see a difference on the elapse when no row returned and into explain plan.

No rows returned in the BIS views

I am new to Discoverer. I had connected to Financials Intelligence responsibility using discoverer desktop. When I tried to create a workbook in General Ledger Business Area to display the GL accounts, I get no rows returned message. I get the same message for any kind of report I try to create not only in GL business area but also in any of the seeded business areas provided by the Oracle. I can query it in toad and see the data but it is not retrieved in discoverer. what could be the problem? is there any profile options to be setup for my username or am I missing something?
Any help is greatly appreciated
Thanks

Here's the metalink note for those interested.
It's basically laying out all the steps to setup the info in Oracle Apps as alluded to by Simon and then perform a complete refresh of the BIS views in the database, bring in the new .eex file for changes, etc.

a. Profile > System
b. Check the 'Site', 'Responsibility' and 'Profiles with No Values' checkboxes
c. Enter "Applications Administration' in 'Responsibility' field
d. Enter FII: GL BIS Discoverer access (if it does not display the profile option, please try wildcard option "FII%GL%BIS%" )

Need to know how to limit the number of rows returned on Oracle

MS SQL Server has a command called 'set row count'.
We are trying to find similar one on Oracle.
What we are trying to do is that instead of using rownum in the query statement, we would like to find way to limit the number of rows returned. I understand that we can use JDBC resultSet object, but that's not what we want.
I know Oracle has one called arraysize, but this would not limit the number of rows returned either.
Pease help.
Thanks

I understand that we can use JDBC resultSet object, but that's not what we want.I'm not sure which feature of ResultSet you use and which not.
But if this question has anything to do with JDBC (that's the forum where you put it), I'd recommend to use Statement.setMaxRows(). This will limit the count of rows which your statement will fetch into it's ResultSet.

Hi,
I've come across a problem with the Oracle XMLTable command as follows:
- I have an XML doc (approx 30Mb) which contains 79k entries
- I have this referenced in Oracle as a BFile
- If I count the number of rows returned by the XMLTable command it does not equal 79k - instead the number is 79k - 65535
Is there a limit on the number of rows XMLTable can handle (ie. < 2 ^ 16) or am I missing something?
declare
xbfile BFILE;
res BOOLEAN;
countrows number;
begin
xbfile := bfilename('XML_DIR', 'test.xml');
res := DBMS_XDB.createResource('/public/test.xml', xbfile);
select count(*) into countrows from XMLTable('for $i in doc("/public/test.xml") return $i/ROWSET/ROW'
columns ID INTEGER);
dbms_output.put_line('count=' || countrows);
end;

Query rows returned VS csv rows downloaded

Does anyone know whether it's possible to have the rows returned by the query to the default of 500 but the actuall rows downloaded in the .csv file to be all the rows that would have been returned from the query? (otherwise the performance of the query is too slow if you try and get the limit of 10,000 rows)
Thanks
Alice

Alice,
You can define the number of rows on a page (using number of rows) and the total number of rows retrieved from your query (using max row count). The total number is whatâs returned when you export your report as a CSV file. And if youâre page renders too slowly when you set the total number of rows to 10000, you could try using the simple pagination style âRow Ranges X to Yâ. With this pagination style, the report would only process your result set up to the max row shown on the current page.

Marc

Why does view WWSBR_USER_FOLDERS return no rows to public ?

Hi,
I want to show a user dependent list of folders in a portal
report application component, but the view
portal30.wwsbr_user_folders does not show public folders to a
public (not logged in) user. The view does not return any rows. I
tested this by creating a portal report on the view, put the
report as a portlet on page. Logout and navigate to the page. The
report portlet shows "No Rows Returned". I would expect to see
the public folders in the report portlet. Am I doing something
wrong ? Is view portal30.wwsbr_user_folders the right view for
this kind of query ?
Environment:
9iAS version 1.0.2.2
Portal patch 3.0.9.8.1
RDBMS version 8.1.7.1.1

This is a bug. As a workaround, create two new views as follows:

The first view adds the condition (WHERE ISPUBLIC=1) to show any
public folder.
Don't change the original view definitions, and be sure you
grant access on WWSBR_USER_FOLDERS2 (or whatever you choose to
call it) to PORTAL30_PUBLIC (or whatever your public portal
schema is called).

Querying view gives multiple rows

I have a query that returns duplicate rows (5) when I write the query this way:
"Select *
from view v
, table_A a
where v.key = a.key"
However, if I write the query this way, the correct data is returned, i.e., only one row.
"Select *
from (select * from view v)
,table_A a
where v.key = a.key"
It also works correctly if I put the in-line view in the select portion of the select statement.
Any ideas?
Thank you for your help,
Tricia

With the second query, I get "ORA-00904: "V"."KEY": invalid identifier". Are you sure that it ran ok for you? v.key is out of scope in the where clause...
If I label the subselect as v, I get the same result as the first query - 5 rows.

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
