Is max function will carry sort operation..?
Hi friends,
Is the max function will perform sort operation in temporary
segments..? Please list the set of operations that will take
place for the following Query (Apart from Syntax & Fetching the
data).
Ex:
delete from tab1 p1
where p1.rowid < (select max(p2.rowid)
from tab1 p2 where
p1.c1 = p2.c2);
Regards,
G. Rajakumar.
you can get that information using explain plan command.

I have apple 4s and the operating system is iOS 5.1.1 got the update message of iOS 6. if update the iOS 6, other functions will work unchanging?
What other functions?
There have been some wifi related issues reported with the 4S being updated to IOS 6. There is no turning back once you update so keep that in mind.
I recommend updating via iTunes so that you make a backup of all your data. You may want to make an iCloud backup as well.
Other than that, I don't understand what other functions you are concerned about? -
Please review following SQL and it's execution plan. Why am I seeing 2 WINDOW SORT operations even though in sql . analytic function "row_number" has been used only once?
Also, In step 3 of the plan, why "bytes" goes from 35 GB(4th step) to 88GB when row count remains the same. In fact , since I'm selecting just 1st row , both row count as well as "bytes" should have gone down. Shouldn't it?

This type of pattern happens quite frequently in parallel execution with aggregation. A layer of slave processes can do partial aggregation before passing a reduced result set to the query co-ordinator to finish the job.
I wouldn't be 100% sure without building a model to check, but I think the logic of your quer allows the eight slaves to identify each "rownumber() = 1" for the data set they have collected, and the allows the query coordinator to do the window sort on the eight incoming rows (for each key) and determine which one of the eight is ultimate the highest date.So is it a normal pattern? Will step#7 & #4 do the same amount work as stated in PREDICATE information part of execution plan.?
You’re correct! There are 8 slave processes appears to be performing WINDOW PUSHED RANK ( Step#7 in Execution Plan ) as you see in following output. Per execution plan and your comment, each one appears to be finding partial set of rows row_num <= 1. It’s apparently doing lots of work and very slow even with 8 processes. So not sure , how slow would be QC doing the same work just by itself.
And as you see below , it’s [Step#7 ] very slow and half of the slaves performing multi pass sort operation. Even though , it was estimated 35GB for that operation, why it’s estimating work area size of only 6-14MB only? Also, It’s allocating so low amount of PGA than expected. P_A_T was set to approx 11 GB. Currently this was the only query/operation on the Instance.
Why it’s not allocating more PGA for that operation? [My apologies for diverting from my original question ].
I have included PGA stats as well here which was taken 5-10 minutes later than other PQ session information. It’s still shows that there is no shortage of PGA.
Moreover, I have observed this behavior (under allocation of PGA) especially for WINDOWS SORT operations for other SQLs too. Is it normal behavior ? I’m on 10.2.0.4.

Hi Everyone,
Am aware of the following flavors of MAX function
1) choose MAX from the folders/fields list (selected items tab)
2) create calculation using: MAX keep dense
3) create calculation using: MAX analytic function
questions, pls:
===========
a) with MAX regular, MAX keep dense, MAX - analytic function
is it necessary to sort it using tools/sort - choose fields to sort by?
or does the data get sorted due to the ORDER BY clause in MAX used in a calculation
b) how to understand the diff. bet. MAX keep dense and MAX - analytic function
1) i understand that analytic functions are applied after detail row processing
does MAX keep dense calculation happen during detail row processing?
2) how did you know to advise when to use MAX keep dense, and when to use MAX - analytic function?
tx for your ideas and assistance, sandraHi,
a) with MAX regular, MAX keep dense, MAX - analytic function is it necessary to sort it using tools/sort - choose fields to sort by? or does the data get sorted due to the ORDER BY clause in MAX used in a calculationIt is only necessary to use a sort if you want to have the rows returned in a specific order. The order by in the max calculation defines the maximum within the group or window. It may affect the order the rows are returned, but if it does this is not guaranteed and you should use a sort on the main query.
b) how to understand the diff. bet. MAX keep dense and MAX - analytic function
1) i understand that analytic functions are applied after detail row processing does MAX keep dense calculation happen during detail row processing?Yes
2) how did you know to advise when to use MAX keep dense, and when to use MAX - analytic function?In general, if you want the result on a single row, so you have one row for each group then you should use the aggregate max. If you want to use the same max on all the rows in the window (defined by the partition) then use the analytic max.

Setting to prevent "Function will be started in new session"
Hi all,
I'm focusing following problem / request.
User A is doubleclicking on a Inforecord number inside a puchase order position (ME23N). Now SAP is showing message MEPO014 (Function will be started in new session) and displaying master data of this inforecord in a new "window" (ME13). If the user has already 6 sessions open, he will get a error message "max. sessions ...!". So far so well.
Now the problem:
User B is doing the same, having already 6 sessions open and ME13 will be displayed in same session (window) where he doubleclicked the inforrecord (ME23N).
question:
is there a setting where i can influence the "new session" behaviour of SAP Gui?

How to use MAX() function with date field
Hi Frzz,
I have created a Graphical calculation view in which i have multiple records for each employee with different dates. But my requirement is to take the records which have maximum date.
I have converted the date into Integer and applied the MAX() function. But still am getting multiple records.
Is there is any other way we can achieve this requirement in Graphical Calculation view?? Your suggestion will really help me.
Thank you.
Krishna.Hmm... what have you tried out so far?
Look, I took the effort and created a little example, just for you
Assume we have a table that contains the logon dates of users.
Every line contains the logon date and some info on the user.
Very much like a not-normalized log file could look like.
Now, the output we want is: one line per user with the most current logon time.
Not too difficult:
1. Have a aggregation node that gives you the distinct user details - one line for every user:
2. Have another aggregation node that gives you the last (MAX) logon date per user:
Finally you do a 1:1 join on the USER_ID and map the result to the output.
Easy as pie

Is it possible to use extension functions in the select attribute of xsl:sort? This way I could sort the nodes based on a computed value.
e.g. <xsl:sort select="myns:myextfunc(ELEM1, ELEM2)">
I tried using a standard XSL function like

Hotspot-clicking (Insert function) plus ALV Sorting
Hi,
I have a requirement where the ALV display has to be SORTED based on values entered/changed on a certain column. The sort works ok when used with a custom APPEND button for new records (always inserted at the bottom of the list).
However, it does not work correctly when used with the Hotspot-click (INSERT functionality). It looks like if you CLICK on a particular record onscreen, you are actually addressing the original record in that position before the SORT was effected.
Is the Hotspot-clicking (Insert functionality) possible with ALV sorting? The ideal solution would be to have the ALV sorted at PBO and also at PAI so that the user can change existing records and add new ones with the sorting being updated everytime ON_DATA_CHANGED is triggered.
Will appreciate any help on this.
Thanks!
MichaelHello Michael
Thanks for further specifying your requirements. I have created the sample variant ZUS_SDN_ALVGRID_HOTSPOT_SORT_1 which contains two differences as compared to its template:
Replace table VBAK with VBAP (so we have two levels of sorting: VBELN, POSNR)
Move SET_TABLE_FOR_FIRST_DISPLAY method call into PBO
When I click on the hotspot (VBELN) a new row entry for the order number is created. The sorting (VBELN, POSNR) is kept even though the new row has been appended to the itab.

Hi,
i'm trying to understand what "buffer sort" operation is in the following explain plan:
0 SELECT STATEMENT
-1 MERGE JOIN CARTESIAN
--2 TABLE ACCESS FULL PLAYS
--3 BUFFER SORT
---4 TABLE ACCESS FULL MOVIE
In Oracle 9i DataBase Performance Guide and Reference, "buffer sort" is not mentioned although all other explain plan's operations are.
What does it mean? Does it take place in main memory or is it an external sort?
Thank you.A BUFFER SORT typically means that Oracle reads data blocks into private memory,because the block will be accessed multiple times in the context of the SQL statement execution. in other words, Oracle sacrifies some extra memory to
reduce the overhead of accessing blocks multiple times in shared memory.
Hope this will clear your doubts.
Thanks. -
Reorganize function will not allow "select rows that match"
I'm trying to sort data in a sheet the same way excel lets you sort by using "filter"
I'm told that using the Reorganize function will allow me to do this especially if I select the "select rows that match" options.
The only problem is that that options is grayed out and I can't use it.
Anybody else have any suggestions or instructions>?
ThanksMake sure you have selected a table

Using Max Function in View Criteria
Hi
I am having a requirement where by i need to make use of max function in view criteria but not able to see any such option. Can someone please help me over it. Here is the requirement.
In table i will be having multiple rows for an employee and i need to pick latest row based on a column say request_id For e.g.
Emp RequestId
A 1
A 2
A 3
A 4
So if i pass the employee id i should get Row Number 4. In simple SQL language I want something like this
select * from emp where empid=A and requestid=( select max(requestid) from emp where empid=A)
Just wanted to know is there any approach that i can use to do all this as part of View Criteria or any other way.
Any help is appreciated!!!
Thanks
AJOne way is this -
1)https://blogs.oracle.com/adf/entry/using_groovy_aggregate_functions_in (You might need to create a self-referencing VL for this , try if it works using a ViewAccessor too)
OR
Order by RequestId descending in your SQL for the VO if thats ok , then have the ViewCriteria for the EmpId and programmatically pickup the first row... -
I have the following tables along with their attributes(the
stared fields show the primary key:
Agent(AgentPhoneNo*, NameOfAgent)
Constituency(ConstituencyNo*,
ConstituencyName,District,RegionCode)
PollingStation(StationNo*,ConstituencyNo*,AgentPhoneNo,
StationName)
VoteResults(Party*, ResultsCategory*,Votes, AgentPhoneNo*)
Results category has two values (S,L) and the number of
parties is variable
My issue is this, below is my code that returns the total
votes received by each party with each constituency. This
query works fine.
<cfquery name="WinningPartyinConstituency"
datasource="#request.datasource#">
SELECT c.ConstituencyName, s.ConstituencyNo, v.Party,
Sum(v.Votes) AS TotalVotes
From (Constituency c
INNER JOIN PollingStation s ON c.ConstituencyNo =
s.ConstituencyNo)
INNER JOIN VoteResults v ON s.AgentPhoneNo = v.AgentPhoneNo
WHERE v.ResultCategory = 'L' AND s.ConstituencyNo IN (Select
ConstituencyNo From Constituency)
Group By c.ConstituencyName, s.ConstituencyNo, v.Party
Order By c.ConstituencyName
</cfquery>
Now I want to check and return the name and total votes of
the party with the maximum votes within each constituency. And but
I can't seem to figure out how to do that, especially because the
max() function takes only to
values.
I will appreciate any guidance on how to write a query that
returns the the party with the maximum votes in each constituency
and the votes it got. TIAMy approach would be to do 2 or 3 Q of Qs to get the numbers
I need. -
Improve built in SQL MAX function
Hi
I am trying to improve the performance of the built in SQL max function. right now searching through over 500,000 rows takes lot of time which can be reduced. Can anyone suggest me something which would be helpful in this or may be give me a link if it has been discussed before?
Anything is appreciated.
ThanksTolls wrote:
Um...considering you were planning on improving on the MAX function, I sort of thought you might actually know how to use it. Otherwise how would you know it was running slowly?thanks Tolls i'd figured it out right after i posted it. i guess i was too excited after reading (you got it in milliseconds) that posted right away without doing anything myself..but yeah it did make it super fast..thanks a lot for your help and time..

Where to go from here? Just execute your damn query. If you really did create the index on the right column and your database isn't stupid and there isn't a lot more to this problem then you told us about like some where clauses then that's it. She's as fast as she's going to get.
