Max number of rows?

Hi,
We have a new implementation of Enterprise X1 3.1 and are trying to determine what determines the maximum number of rows that can successfully be generated using Webi. Is there a hard limit that Webi has (assuming the Universe max rows is deactivated)?
Also, is there a limit for Live Office extractions into Excel? What are the main drivers for this limit?
Finally, all other factors being equal, are there different limits for the number of rows a query can return successfully in Webi vs Deski vs BEx? How does the performance of these three tools compare to each other in terms of speed?
Thanks!
Darryl

Thanks for your reply! I also got a response back from SAP / BObj that I'll share:
Q) We have a new implementation of Enterprise X1 3.1 and are trying to determine what determines the maximum number of rows that can successfully be generated using Webi. Is there a hard limit that Webi has (assuming the Universe max rows are deactivated)?
=> There is a limit to the number of pages Web Intelligence reports can have. This is because there are a maximum number of pages (per report) the server can process. This number depends on the paper size chosen. Generally, it is approximately 590000 inches vertically by 590000 inches horizontally. Therefore, if you choose a smaller paper size, you get more pages but may not see all the pages of the report.
Resolution:
To work around this behavior, you can either make each line smaller to get more records, or split your report into more than one report to see all your data.
Q) Is there a limit for Live Office extractions into Excel? What are the main drivers for this limit?
=> By default its set to 512 rows and columns....however you can change this by modifying the Liveoffice_config.properties file...you can locate this file in /dswsbobje/lib/dsws_liveoffice_provider.jar.
Q) Are there different limits for the number of rows a query can return successfully in Webi vs. Deski?
=> Although there is no official limit on the number of rows that can be handled by DeskI, it is really not meant to be used like a database, i.e. for returning millions of rows. The purpose of BusinessObjects reporting tools is to get useful information, which is not possible with millions of rows.
=> It has been observed that when the number of rows increases beyond 1.5 million approximately, it starts affecting the Desktop Intelligence performance. This behavior may vary from machine to machine depending upon the available resources and programs (processes) running in the background.
=> The limit is related to the number of rows those can actually be displayed in the report and not how many can be loaded into the data cube. All the rows get loaded in the cube however when it comes to rendering them in the report the problem may arise.
Example: Report A returns 2 million rows into the cube however due to the report design there are only 200 rows in the actual report page and can be run successfully. Report B tries to render all 2 million rows into the actual report page and can fail.
Workaround:
Use filters in the report so that it will retrieve less number of rows and will also help to display useful data.

Max number of rows in a BEX structure

Hi gurus,
we need to create a structure with 164 key figures, and before starting doing it, does anybody knows which is the max number of rows that can be created on a BEX structure?
I'm not asking about max number of rows on a query, i'm asking about the number of entries that you can manually create on a structure. Is there a maximum?
Thanks in advance,

How to set max. number of rows in a table?

Hi,
I'm working on a SCADA interface. In this application there are different tables with vertical scroll bar.
I prefer to make visible only the initialized rows (I've initialized 40 blank rows of a table with a string array). Since the window not contain all 40 rows but only 20 rows, I set the rows number of "table properties window" to 20; so I added a vertical scroll bar.
Now, when a user scroll the scroll-bar, he can view not only the 40 rows initializated, but an undefined number of rows.
There's a way to visualize only a limited number of rows?
Thanks in advance!

Max number of rows to display in a pivot table

I have a pivot table with two row levels and I need to fix the max amount of rows to display at the second level to five. Can I do that on excel 2013?
Example
Row Levels
Machine A
Part 1 (to be displayed)
Part 2 (to be displayed)
Part 3 (to be displayed)
Part 4 (to be displayed)
Part 5 (to be displayed)
Part 6 (not displayed)
Machine B
Part 1 (to be displayed)
Part 2 (to be displayed)
Part 3 (to be displayed)
Part 4 (to be displayed)
Part 5 (to be displayed)
Part 6 (not displayed)
and so go on.

Hello,
you can use a filter to display only the top 5 items of the second level, based on their value. To do that, right-click on a label in the second level, then select Filter > Top 10. Change the 10 to a 5 in the next dialog.
You can also create a label filter, but it only takes one filter condition.
Another way is to select the rows you don't want to be shown, then use right-click > Filter > Hide Selected Items

Table's max number of rows

Hi,
I am a newbie to Oracle and I would like to get you comment of the following questions:
1. What it the maximun number of rows that a table should have in order to be adequately handled in the sense of Create, Read, Update and Delete?
2. To be more specific , let say I have the following table:
file_id (INT)
senetence_id (INT)
sentence (CLOB)
Primary key (file_id, senetence_id)
The queries I would like to do are:
select - select all sentences for a certain file_id
insert - insert a new sentence (for a specific file_id)
delete - delete a sentence for a specific file_id.
search - get all sentences that contain a specifc string
The table's size is going to growth and could get to millions and even more.
Could i get into a point where I couldn't "work" with the table.
Thank you in advance for your assitance

Hi,
Welcome to forums.oracle.com
I am not sure of what you are looking for, DB itself used for storing information irrespective of Size of data (as its going to increased day by day).
The queries I would like to do are:
select - select all sentences for a certain file_id
select *
from <table_name>
where file_id = <specific_fileid>
insert - insert a new sentence (for a specific file_id)
insert into <table_name>
select <specific file_id>, <sentence>,EMPTY_CLOB()
from dual
or
insert into <table_name> values (<specific file_id>, <sentence>,EMPTY_CLOB())
delete - delete a sentence for a specific file_id.
delete from <table_name> where file_id = <specific file_id>
search - get all sentences that contain a specifc string
select from <table_name> where file_id = <specific file_id>
I could not able to understand further, are you looking specific to CLOB in your table. ??

BEx 7.X + MS Excel 2007 - Max number of Rows

Hi,
I've been looking for some way to show more than 65k rows in Excel 2007 using BEx Analyzer 7.X.
I have a customer that has this issue. I know that use more than 65k rows is not a property of a BI report and reports with more than 65k rows would have problems with performance, but my customer has this issue.
Do you know some way to solve this problem? Can Excel 2007 + BEx Analyzer 7.X show more than 65k rows?
Thanks,
Best Regards,
Marco Muniz

Hi Marco,
as far as I know in Excel 2007 it is possible to show
1,048,576 rows by 16,384 columns

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,
raj

How To Restrict Number Of Rows For Multiple Group In Report Output

Hi ,
I have a requirement to restrict number of rows in report output.I have three different group , if i use same no of rows to restrict then output is as expected but if i want Deduction group should have 7 rows , earning should have 5 rows and Tax group have 3 rows in report output then XML tag is not working.
Below is the XML tag i am using -
First i have declare the variable to restrict the rows -
<xsl:variable name="lpp" select="number(7)"/>
<xsl:variable name="lpp1" select="number(5)"/>
<xsl:variable name="lpp2" select="number(3)"/>
For Each -
<?for-each:PAYSLIP?>
<xsl:variable xdofo:ctx="incontext" name="DedLines" select=".//AC_DEDUCTIONS"/>
<xsl:variable xdofo:ctx="incontext" name="EarLines" select=".//AC_EARNINGS[ELEMENT_CLASSIFICATION!='Taxable Benefits']"/>
<xsl:variable xdofo:ctx="incontext" name="EarTaxLines" select=".//AC_EARNINGS[ELEMENT_CLASSIFICATION='Taxable Benefits']>
<?for-each:$DedLines?><?if:(position()-1) mod $lpp=0?> <xsl:variable name="start" xdofo:ctx="incontext" select="position()"/>
<?if:(position()-1) mod $lpp1=0?><xsl:variable name="start1" xdofo:ctx="incontext" select="position()"/
<?if:(position()-1) mod $lpp2=0?><xsl:variable name="start2" xdofo:ctx="incontext" select="position()"/>
Report output is tabular form (one page has two column - Earning and Deduction ) . Tax group comes below earning group.
Deduction Group -
<?for-each-group:$DedLines;./REPORTING_NAME?><?if:position()>=$start and position()<$start+$lpp?>
<?REPORTING_NAME?>
<?end if?><?end for-each-group?>
Earning Group -
<?for-each-group:$EarLines;./REPORTING_NAME?><?if:position()>=$start1 and position()<$start1+$lpp1?>
<?REPORTING_NAME?>
<?end if?><?end for-each-group?>
Tax Group -
<?for-each-group:$EarTaxLines;./REPORTING_NAME?><?if:position()>=$start2 and position()<$start2+$lpp2?>
<?REPORTING_NAME?>
<?end if?><?end for-each-group?>
Please let me know in case additional detail is require.
Thanks in Advance.
Thanks,
Harsh

variable lpp2 is declare to restrict EarTaxLines -
<xsl:variable name="lpp2" select="number(2)"/>
This will help to restrict the no of rows on one page , if we have more then two tax benefits line then layout will roll over to continuation page.
As part of report output my expectation is if i restrict Earning , Deduction and Tax benefits to same no of line for example - variable lpp ,lpp1 and lpp2 have same value "number(2)" , we can see the layout is continue on next page (restrict every group can have max two lines) .This is the reason we have 4 header grid , deduction and Tax Benefit lines are rolled over to continuation page .But if we restrict different value for each variable then continuation page layout is missing .
When we tried for <xsl:variable name="lpp2" select="number(3)"/> value continuation page layout is not getting generate for both employee number .

Ok, that only was to show simply that max option
might not an option to reduce execution time.Yes, but I/O variances have a tendency to really skew the observed elapsed execution time - making execution time alone a poor choice to determine what SQL will perform better than another.
Both MAX(ROWNUM) and COUNT(*) results in the same amount of I/O - as both uses the exact same execution plan, I/O wise. In this example, a FTS.
SQL> create table testtab nologging as select * from all_objects where rownum < 10001;
Table created.
-- warmed up the buffer cache with a couple of SELECTs against TESTAB in order
-- to discard PIOs from the results
SQL> set autotrace on
SQL> select count(*) from testtab;
COUNT(*)
10000
Execution Plan
Plan hash value: 2656308840
| Id | Operation | Name | Rows | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 35 (9)| 00:00:01 |
| 1 | SORT AGGREGATE | | 1 | | |
| 2 | TABLE ACCESS FULL| TESTTAB | 9262 | 35 (9)| 00:00:01 |

So seeing that we have the exact same baseline for both queries, and that PIO does not influence the results, we time a 1000 executions of both.

This shows that what makes the MAX() more expensive is just that - determining the MAX(). For each row, Oracle has to call its internal MAX() function with two values - the current max result and the new value. This function then returns the new max value. This overhead per row adds up to a significant overhead in execution time - making the MAX() approach 5x slower than the COUNT() approach.

How to get the number of rows written to the header of the spool file.

Hi
I need to create a header line for the spool file .
the header line should include fixed length values .
The header should include the number of records found in the table with a maximum begin date (begin_date is the column of the table)
To get the header in the spool file , i wrote a select query has :-
--SPOOL 'C:\Documents and Settings\abc\Desktop\output.TXT'
select 'W'||to_char(sysdate,'MM/DD/YYYYMi:HH:SS')||lpad(max(rownum),9,'000000000') ||'R'||max(to_char(school_from_date,'MM/DD/YYYY')) ||
rpad(' ',76,' ')
from dad.school
group by sysdate;
SPOOL OFF
which gets me all the rows in the table , but i only want the rows with the latest school_begin_date .
how can i achieve that ...
I know that a subquery should be written in the from clause to get the number of rows found with a maximum school_begin_date.
select 'W'||to_char(sysdate,'MM/DD/YYYYMi:HH:SS')||lpad(max(rownum),9,'000000000') ||'R'||max(to_char(school_from_date,'MM/DD/YYYY')) ||
rpad(' ',76,' ')
from dad.school where
select rownum from dad.school
where school_begin_date = max(school_begin_date) ;
the error i get is
ORA-00934: group function is not allowed here
I NEED HELP ..IN GETTING THE ROWNUM JUST FOR THE LATEST BEGIN_DATE ?
PLS HELP ME IN WRITING THE QUERY .
THANKS IN ADVANCE .

Try this:
select 'W'||to_char(sysdate,'MM/DD/YYYYMi:HH:SS')||lpad(max(rownum),9,'000000000')||'R'||max(to_char(school_from_date,'MM/DD/YYYY')) || rpad(' ',76,' ')
from dad.school
where school_begin_date = (select max(school_begin_date)
from dad.school);

How to Efficiently Sample a Fixed Number of Rows

Good afternoon. I need to select a specific number of random rows from a table, and while I believe my logic is right it's taking too long, 30 minutes for a routine data size. Hopefully someone here can show me a more efficient query. I've seen the SAMPLE function, but it just randomly selects rows on a one-by-one basis, without a guaranteed total count.
This is the idea:
INSERT INTO Tmp_Table (Value, Sequence) SELECT Value FROM Perm_Table, DBMS_RANDOM.VALUE;
SELECT Value FROM Tmp_Table WHERE ROWNUM <= 1234 ORDER BY Sequence;I'd need to put the ORDER BY in a subselect for ROWNUM to work correctly, but anyway that's just an illustration. My actual need is a little more complicated. I have many sets of data; each set has many rows; and for each set I need to return a specific (different) number of rows. Perhaps project A has three rows in this table, and I want to keep two of them; project B has two rows, and I want to keep one of them. So I need to identify, for each row, whether it's valid for that project. This is what my data looks like:
Project Person Sequence Position Keeper
A       Bill    1234     1        Yes
A       Fred    5678     3        No
A       George 1927     2        Yes
B       April   5784     2        No
B       Janice 2691     1        YesI populate Sequence with random values, then calculate the position of each person within their project, and finally discard people who's Position is greater than Max_Targets for the Project. Fred and April have the highest random numbers, so they're cut. It's not the case that I'm just trimming one person from each project; the actual percentage kept will range from zero to 100.
Populating the list with random values is not time-consuming, but calculating Position is. This is my code:
UPDATE Tmp_Targets T1
SET Position =
SELECT
   COUNT(*)
FROM
   Perm_Targets PT1
   INNER JOIN Perm_Targets PT2 ON PT1.Project = PT2.Project
   INNER JOIN Tmp_Targets T2 ON PT2.Target = T2.Target
WHERE
       T1.Target = PT1.Target
   AND T2.Sequence <= T1.Sequence
);The Target fields are PKs, and the Project and Sequence fields are indexed. Is there a better way to approach this? I could write a cursor that pulls out project codes and performs the above operations for each project in turn; that would be logically simpler and possibly faster. Has anyone here addressed a similar problem before? I'd appreciate any ideas.
This is on 9.2, in case it matters. Thank you,
Jonathan

You've not given any indication of how max targets for a given project is determined, so for my example I'm using the ceiling of 1/2 of the number of records in each project which gives the same number of yes and no responses per project as you had:
with dta as (
select 'A' project, 'Bill' person from dual union all
select 'A', 'Fred' from dual union all
select 'A', 'George' from dual union all
select 'B', 'April' from dual union all
select 'B', 'Janice' from dual
), t1 as (
select project
       , person
       , row_number() over (partition by project order by dbms_random.value) ord
       , count(*) over (partition by project) cnt
       , rownum rn
    from dta
select project
     , person
     , ord
     , cnt
     , case when ord <= ceil(cnt/2) then 'Yes' else 'No' end keep
from t1
order by rn
PROJECT PERSON ORD                    CNT                    KEEP
A       Bill   2                      3                      Yes
A       Fred   3                      3                      No
A       George 1                      3                      Yes
B       April 1                      2                      Yes
B       Janice 2                      2                      No
5 rows selectedIn this example I use an analytic function to assign a random ordering for each record within a project in the middle query, in the final output query I am determining the yes no status based on the order within a project and the count of records in the project. If you had a table of projects indicating the thresh hold you could join to that and use the thresh hold in place of the ceil(cnt/2) portion of my inequality in the case statement.

Max number of records in an internal table

Hi,
Can any one tell me what is the Max Number of records we can get into an internal table.
if you have any link of sap help on this please FWD.
thanks in Adv.
Regards,
Lakshmikanth.T.V

Hi lakshmikanth,
Internal Tables as Dynamic Data Objects
Internal tables are always completely specified regarding row type, key and access type. However, the number of lines is not fixed. Thus internal tables are dynamic data objects, since they can contain any number of lines of a particular type. The only restriction on the number of lines an internal table may contain are the limits of your system installation. The maximum memory that can be occupied by an internal table (including its internal administration) is 2 gigabytes. A more realistic figure is up to 500 megabytes. An additional restriction for hashed tables is that they may not contain more than 2 million entries. The line types of internal tables can be any ABAP data types - elementary, structured, or internal tables. The individual lines of an internal table are called table lines or table entries. Each component of a structured line is called a column in the internal table.

keerthi.

How do you change the number of rows returned by an advanced datagrid...Only displays 1000 rows....I

I am using coldfusion to query an oracle table....Query returns approximately 2000 rows, however the max rows the datagrid will display is 1000. Does anybody know how to change this...THANKS!!

Thanks so much for your answer that sounds like a good idea...
I found the answer to my initial problem...In my coldfusion I had set maxrows = 1000. So the datagrid was always returning 1000 records even when a lot more than that should have been returned...When I removed the maxrows parameter in the coldfusion code, my datagrid was now been populated with the correct number of rows...
thanks again for your help,
