Use of MAX function

Hi,
I am using parent-child hierarchy and in my reports I want to show Max(hierarchy_level). When I use the function MAX directly in the report it works fine in every way. But I want to have this kind of column in the BI Server presentation catalog so the user does not need to add MAX in Analysis/Answers (this is 11g). Normally this would imply a Max(hierarchy_level) as a logical function, but in the BI Server it is not allowed with MAX function in the logical function so it does not work.
The hierarchy level is just a column from a dimension table and creating it as a fact column is not a very good solution. I also tried to solve this in many different ways, but only the MAX funtion in Analysis/Answers allways give the correct result. Used in combination with other dimensions etc. I want the exact same behaviour as I get when using MAX in analysis.
Any good ideas to solve this? Is there another function in the BI Server that works the same way as MAX ?

Very often, about a primary key, see for example our italian accounting application (our VAT invoices:fatture IVA) ), where the holes might be a problem.
Yes Rosario, of course I know that, and that's why I said "in this scenario" : if primary key is the only purpose, I don't think holes could be a problem.
Buona giornata anche a te.

Use of MAX function in Query Designer

Dear all,
i want to create a report that gives ONE line per period that holds the MAX of several lines per period. So NO addition of the KF but just one line item.
I tried to use the MAX function and/or MAX drop-down boxes via properties on KF,
but they all provide the wrong result (mostly the MAX after summaction of the KF).
Any ideas ??
Greetz,
Herman

Hi Herman
Please check the KF infoobject property which might have been set to Summation. You need to change the property of the KF to MAX if you wish to have MAX value.
Hope this might be helpful to you
Thanks

Using the max function in a inner joined statement

I am trying to take from a database with two joined tables various datas from the record belonging to paul that has the highest entry number.
String query = "SELECT Table1.name, Table1.idNumber, Table2.Address Table2.entryNum FROM Table1 INNER JOIN Table2 ON Table1.idNumber = Table2.idNumber WHERE Table2.entryNum = max ( Table2.entryNum) AND Table1.name = 'Paul'";

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...

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 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

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)...

MAX Function not returning MAX

I have a query that is pulling in EDI 214 status codes, and want to pull in the last received status for status type "AG". To do this, I'm using the MAX function on the INSERT_DATE field of the status code AG, but the query keeps returning both AG status codes. I've tried this in a single query (Query 1) but it did not work so I also attempted it in a much smaller query to be used as a subquery, but that still did not work. Can anyone identify what the issue is with what I'm attempting to do?
Query 1 (All Inclusive):
SELECT BS.SHIPMENT_GID AS BUY_SHIPMENT_GID,
AGSS.EVENTDATE AS AG_EVENT,
D1SS.EVENTDATE AS D1_EVENT,

I appreciate any help.

Hi, Adam,
Welcome to the forum!
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
Simplify the problem as much as possible. Remove all tables and columns that play no role in this problem.
If you can show what the problem is using commonly available tables (such as those in the scott schem) then you don't have to psot any sample data; just the results and the explanation.
Always say which version of Oracle you're using.
See the forum FAQ {message:id=9360002}
MAX (insert_date) returns the latest insert_date. I think, in this problem, you don't really want the latest insert_date; you want the status code that's related to the last insert_date. One way to get that is the aggregate FIRST (or LAST) function.
Consider this query, using the scott.emp table:
SELECT       ename
,       hiredate
FROM       scott.emp
ORDER BY hiredate
,            ename
;Output:
ENAME      HIREDATE
SMITH      17-Dec-1980
ALLEN      20-Feb-1981
WARD       22-Feb-1981
JONES      02-Apr-1981
BLAKE      01-May-1981
CLARK      09-Jun-1981
TURNER     08-Sep-1981
MARTIN     28-Sep-1981
KING       17-Nov-1981
FORD       03-Dec-1981
JAMES      03-Dec-1981
MILLER     23-Jan-1982
SCOTT      19-Apr-1987
ADAMS      23-May-1987Say we're only interested in seeing the last hiredate, and the name of the person hired on that date:
LAST_ENAME LAST_HIREDA
ADAMS      23-May-1987Here's how to get those results using the aggregate LAST function:
SELECT       MIN (ename) KEEP (DENSE_RANK LAST ORDER BY hiredate) AS last_ename
,       MAX (hiredate)                                              AS last_hiredate
FROM       scott.emp
;What if there's a tie for the latest hiredate? For example, say we're only looking at people hired before 1982. In that case, the latest hiredate is December 3, 1981, and there happen to be two people hired on that date. This query
SELECT       MIN (ename) KEEP (DENSE_RANK LAST ORDER BY hiredate) AS last_ename
,       MAX (hiredate)                                              AS last_hiredate
FROM       scott.emp
WHERE        hiredate     < DATE '1982-01-01'
;produces only 1 row of output:
LAST_ENAME LAST_HIREDA
FORD       03-Dec-1981Why did it show FORD rather than JAMES? Because of the MIN function. When there happens to be a tie for the latest hiredate, MIN says to return the first ename (in normal sort order) of the rows that have that hiredate.
FIRST and LAST work with GROUP BY, too.
In the example above, we were only looking at one column related to the latest hiredate. If we neede to see several columns, it would be simpler to use the analytic ROW_NUMBER function:
WITH     got_r_num     AS
     SELECT emp.*
     ,     ROW_NUMBER () OVER ( ORDER BY hiredate DESC
                               ,            ename
                       ) AS r_num
     FROM    scott.emp

I hope this answers your question.
If not, post a more complete explanation of what you want to do. if you have to use your own tables, then post CREATE TABLE and INSERT statements for a little sample data. Post the results you want from that data, and explain how you get those results from that data.

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
FROM
( SELECT ITEM_KEY, ROW_NUMBER() OVER(ORDER BY BEGIN_DATE DESC) RN FROM
WF_ITEMS WHERE ITEM_TYPE = 'xxxxzzzz' AND ROOT_ACTIVITY = 'START_REQUESTS'
AND SUBSTR(ITEM_KEY,1,INSTR(ITEM_KEY,'-') - 1) = :B1
) T WHERE RN <= 1
call count cpu elapsed disk query current rows
Parse 0 0.00 0.00 0 0 0 0
Execute 1 0.00 1.57 0 0 0 0
Fetch 1 8700.00 544968.73 8180 8185 0 0
total 2 8700.00 544970.30 8180 8185 0 0
many 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.
