Max function in select statemnt

Hi,
   Can someone help me with what is wrong in the following query...How to use the max function
in ABAP program select statement??
Thanks..
LOOP AT IT_ANLA_ANLZ INTO WRK_ANLA_ANLZ.
SELECT KANSW
            FROM ANLC INTO TABLE IT_ANLC WHERE GJAHR IN ( SELECT MAX(GJAHR) FROM ANLC ) and ANLN1 = WRK_ANLA_ANLZ-ANLN1
            AND BUKRS = WRK_ANLA_ANLZ-BUKRS .
APPEND IT_ANLC.
ENDLOOP.

Hi,
You have write your select query once,
and then loop on the internal table into
which data will get populated for its display.
SELECT KANSW
FROM ANLC INTO TABLE IT_ANLC WHERE GJAHR IN
( SELECT MAX(GJAHR) FROM ANLC ) and ANLN1 = WRK_ANLA_ANLZ-ANLN1
AND BUKRS = WRK_ANLA_ANLZ-BUKRS .
Then loop at internal table:
LOOP AT IT_ANLA_ANLZ INTO WRK_ANLA_ANLZ.
write: / wrk_anla_anlz-fields.
Endloop.
Hope it helps
Regards

Use COUNT or MAX functions inside of a query, and you have no data found

I'm writing a query with a COUNT and a MAX function.
    SELECT li.id
             , MAX(m.display_date)
            , COUNT(*)
     FROM li JOIN m ON (m.LIID=li.LIID)
    WHERE m.DISPLAY_DATE < SYSDATE - 7
    GROUP BY li.id;I would like to write a query that returns always a row foe each row in the table li.
If there are no records with the condition "WHERE m.DISPLAY_DATE < SYSDATE - 7", I would like to have a row with
- COUNT(*) = 0
- MAX(m.display_date) = TO_DATE('2010-06-08', 'YYYY-MM-DD'

MAX function

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, sandra

Hi,
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.

Using max function in PL/SQL

VERY URGENT...
Am new to oracle...
I've written a package that display gif images in form of histogram/bar chart. using html,
I need to use max function to display values proportionately.
please help. i need to complete this assignment by 2/9/00 by 10.00 am at the latest. I've half written a function but I don't know if there's a simpler way fo doing this. html enabled

First of all Thanks to all gentlemen who replied ..many thanks ...
Tried the ROW_NUMBER() option but still it is taking time...have given output for the query and tkprof results as well. Even when it doesn't fetch any record ( this is a valid cased because the input header id doesn't have any workflow request submitted & hence no entry in the wf_items table)..then also see the time it has taken.
Looked at the RANK & DENSE_RANK options which were suggested..but it is still taking time..
Any further suggestions or ideas as to how this could be resolved..
SELECT 'Y', 'Y', ITEM_KEY

It was worked fine until now....
Now i used the same query...
But the result is
MAX(ID)

Please help me... What is the reason?
I want the correct result...
Thanks in advance....

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
AJ

One 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...

Problem with max function in air

Hello ,how are you,I write this query : [b]SELECT *, max(trackerId) FROM sessiontracker [/b]in
sqlite manager and it works ,but when I use it in Air application ,it send me back this error:
ReferenceError: Error #1056: Cannot create property max(trackerId) on
com.afarinesh.models.SessionTracke
,I guess that Actionscript 3 can not pars max function.
I appreciate your help

Hello,
AIR does support max function. Please see Page 1067 of the actionscript developer's guide, which can be download from http://help.adobe.com/en_US/as3/dev/as3_devguide.pdf. And I tried the max function in my AIR application: create a table, insert some records into the table, and use the "select *, max(column) from table". It works fine.
I noticed your error is the ReferenceError and related to some AS class. So I am not sure if you use any ORM tool. If so, the issue may be caused by the use of the tool. Please check the configuration and usage of the tool.
Thanks,

Max value without using max() function

Hi
Is there any way to get the max value from a table without using MAX() function
Thanks

well if you think about it i'm sure you'll find a solution
what does max(field) means, it simply is the value of the field where no other value of the same field that is > than this value exists.
consider the following :
table TAB(
fld NUMBER(5));
translate the logic and you'll have
select a.fld from TAB a where NOT EXISTS(select b.fld from TAB b where b.fld>a.fld) and rownum=1;
of course there are better ways i'm sure, you'll just have to figure'em out.

Using Max function

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. TIA

My approach would be to do 2 or 3 Q of Qs to get the numbers
I need.

Bug? using MAX() function on char(1) column returns something larger

details:
-- we have a complex nested query, where we are essentially returning the max() value into a variable
-- the max() function is being used on a char(1) column
-- where MAX() is part of an inner select, we have started getting
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
errors.
SELECT MAX(X) INTO var FROM ... works in 9i and 10g
SELECT X INTO var FROM (SELECT MAX(X) X FROM ... worked in 9i, does not work in 10g!
-- We never had problems with the code until upgrading to 10g release 2.
-- the Solution is to cast the final value with TO_CHAR(). The cast MUST be done at the outer most point of the select:
SELECT TO_CHAR(X) INTO var FROM (SELECT MAX(X) X FROM ... works
SELECT X INTO var FROM (SELECT TO_CHAR(MAX(X)) X FROM ... causes an error!

I certainly looks like a bug, but you should raise an iTAR on Metalink since Oracle does not monitor this forum.
I was able to replicate your results on my 10.2.0.1 database.
There is an easier workaround than yours. Try
ALTER TABLE sql_bug_test MODIFY (z VARCHAR2(1));That seems to eliminate the problem on my instance.

Max() function in Data services

Hi Experts,
i'm using Data services (etl), and working on budget table(ms sql table),
1. the table has a field [budget amount] and [version_no],
2. before i extract the budget amount i need to know the highest version in [version_no] fields
3. can any body help me on this? i tried to use the script: ifthenelse(max(version-no),budget_amount, 0) but it retuns error when validation.
please help me on this:
thanks in advance
Archie72

Hi,
Connect a Query transform say Query1 from the source table
Inside Query1
select MAX(version no) into the output. Do not select the other budget field into the output.
Connect another Query transform say Query2 from the source table. Connect the output of Query1 also into Query2.
Inside Query2:
Join the source table and Query 1 in where
Query1.version no = SourceTable.version no
Select version no and budget into Query 2 output and connect it to target table.
Assuming that the source table has only version number and budget. You might have to tweak and make use of Group By as required where you use the MAX() function. SourceTable mentioned in the where condition will be replaced with your exact source table name

Max Function in @Prompt

Hi,
We have a week dimension in our Cal table. The user wants to use a condition where if he will enter week number (for eg: 13-2009) then data of that particular week should be displayed and if he will enter ' * ' then data of last week in the table will be displayed.
To fetch the last week we can use max(cal.week). But how to use it in prompt? Because when I am using max function then getting an error that group functions are not supported in prompt. Below is the prompt condition I am using:
CAL.WEEK IN (decode(@Prompt('Enter week (or * for last week)', 'A',, MONO,FREE),'*',(MAX(CAL.WEEK)),@Prompt('Enter week (or * for last week)', 'A',, MONO,FREE)))
I tried it by creating an object for MAX(CAL.WEEK) and then tried to use it in prompt, but since prompt doesnot support it, this object was not visible in the object list while creating the prompt.
Please help.
Thanks,
Kirti

The problem you are facing is that a condition containing a grouping function belongs in the having close, not in the where...
There is no way to create something in the universe that will be put in the having clause.
So what you need is to put it in as subselect, which can go in the where.
Try the predefined filter like this...
(CAL.WEEK = @Prompt('Enter week (or * for last week)', 'A',, MONO,FREE)
OR (@Prompt('Enter week (or * for last week)', 'A',, MONO,FREE)='*'
AND CAL.WEEK=(SELECT max(C2.WEEK) FROM CAL C2)))
Do not forget the brackets around the two conditions with OR
Good luck,
Marianne

Usage of MAX Function.

Hi,
One of our customers is facing an error while executing a PL/SQL block like,
declare
l_flag varchar2(30);
begin
select max('Y') into l_flag from v$database; -- Can use any table here
end;
however, when the select query is changed to as follows, no error is seen.
select substr(max('Y'),1,30) into l_flag from v$database;
Can someone please help me in identifying what could be issue?
Thanks,
Dola

We are actually trying to check if the table contains any rows.Hmmm, I would have thought that using a MAX() function to do that is rather expensive (if it's a large table)...
