Help with analytical function
I successfully use the following analytical function to sum all net_movement of a position (key for a position: bp_id, prtfl_num, instrmnt_id, cost_prc_crncy) from first occurrence until current row:
SELECT SUM (net_movement) OVER (PARTITION BY bp_id, prtfl_num, instrmnt_id, cost_prc_crncy ORDER BY TRUNC (val_dt) RANGE BETWEEN UNBOUNDED PRECEDING AND 0 FOLLOWING) holding,
what i need is another column to sum net_movement of a position but only for the current date, but all my approaches fail..
- add the date (val_dt) to the 'partition by' clause and therefore sum only values with same position and date
SELECT SUM (net_movement) OVER (PARTITION BY val_dt, bp_id, prtfl_num, instrmnt_id, cost_prc_crncy ORDER BY TRUNC (val_dt) RANGE BETWEEN UNBOUNDED PRECEDING AND 0 FOLLOWING) today_net_movement
- take the holding for the last date and subtract it from the current holding afterwards
SELECT SUM (net_movement) OVER (PARTITION BY bp_id, prtfl_num, instrmnt_id, cost_prc_crncy ORDER BY TRUNC (val_dt) RANGE BETWEEN UNBOUNDED PRECEDING AND -1 FOLLOWING) last_holding,
- using lag on the analytical function which calculates holding fails too
I also want to avoid creating a table which stores the last holding..
Does anyone sees where I make a mistake or knows an alternative to get this value?
It would help me much!
Thanks in advance!
Thank you,
but I already tried that but it returns strange values which are not the correct ones for sure.
It is always the same value for each row, if its not 0, and a very high one (500500 for example), even if the sum of all net_movement of that date is 0 (and the statement for holding returns 0 too)
I also tried witch trunc(val_dt,'DDD') with the same result (without trunc it is the same issue)
please help if you can, thanks in advance!

I need help with Analytic Function
Hi,
I have this little problem that I need help with.
My datafile has thousands of records that look like...
Client_Id Region Countries
[1] [1] [USA, Canada]
[1] [2] [Australia, France, Germany]
[1] [3] [China, India, Korea]
[1] [4] [Brazil, Mexico]
[8] [1] [USA, Canada]
[9] [1] [USA, Canada]
[9] [4] [Argentina, Brazil]
[13] [1] [USA, Canada]
[15] [1] [USA]
[15] [4] [Argentina, Brazil]
etc
My task is is to create a report with 2 columns - Client_Id and Countries, to look something like...
Client_Id Countries
[1] [USA, Canada, Australia, France, Germany, China, India, Korea, Brazil, Mexico]
[8] [USA, Canada]
[9] [USA, Canada, Argentina, Brazil]
[13] [USA, Canada]
[15] [USA, Argentina, Brazil]
etc.
How can I achieve this using Analytic Function(s)?
Thanks.
BDFHi,
That's called String Aggregation , and the following site shows many ways to do it:
http://www.oracle-base.com/articles/10g/StringAggregationTechniques.php
Which one should you use? That depends on which version of Oracle you're using, and your exact requirements.
For example, is order importatn? You said the results shoudl include:
CLIENT_ID COUNTRIES
1 USA, Canada, Australia, France, Germany, China, India, Korea, Brazil, Mexicobut would you be equally happy with
CLIENT_ID COUNTRIES
1 Australia, France, Germany, China, India, Korea, Brazil, Mexico, USA, Canadaor
CLIENT_ID COUNTRIES
1 Australia, France, Germany, USA, Canada, Brazil, Mexico, China, India, Korea?

If you'd like help, post your best attempt, a little sample data (CREATE TABLE and INSERT statements), the results you want from that data, and an explanation of how you get those results from that data.
Always say which version of Oracle you're using.

Help with analytical function (ora 9...)
Hi everyone, is there a way to fill some missing numbers based on what have come before and after that missing number by starttime and based on how many missing data are between? ... by "simple" select? I know how to do that just theoreticly with simple math commands, but is there a way to apply them in sql (analytical functions)?
Thanks in advance for any ideas !
The missing number on line 17 could be calculated as 339+(1/2)*(356-339) = 347,5
The missing number on line 23 could be calculated as 355+(1/3)*(292-355) = 334
The missing number on line 24 could be calculated as 355+(2/3)*(292-355) = 313

Hello.
I am not used to anaylitic funtions and after reading a lot about them I am very confused.
I have a situation similar to the test_table I post below, I have a table with 2 columns event_code (number) and event_date (date) which make the primary key. I need to see all the event_code's and event_date's of the table, I also need to compare the columns value1 and value2 so that if value1>value2 and event_date for that record belongs to september of 2008 it takes the value 1 (0 otherwise):
WITH test_table AS
(SELECT 1 event_code, ADD_MONTHS (SYSDATE - 1, -3) event_date, 1 value1,
1 value2
FROM DUAL
UNION
SELECT 1 event_code, ADD_MONTHS (SYSDATE - 1, -2) event_date, 3 value1,
2 value2
FROM DUAL
UNION
SELECT 1 event_code, ADD_MONTHS (SYSDATE - 1, -4) event_date,

Hi,
Please find below table structure and insert scritps. Requesting for vluable help.
create table temp2 (col1 number,col2 varchar2(10),col3 number,col4 varchar2(20));
insert into temp2 values (1,'a',100,'vvv');
insert into temp2 values (2,'b',200,'www');
insert into temp2 values (3,'c',300,'xxx');
insert into temp2 values (4,'d',400,'yyy');
insert into temp2 values (5,'e',500,'zzz');
insert into temp2 values (6,'f',600,'aaa');
insert into temp2 values (7,'g',700,'bbb');
insert into temp2 values (8,'h',800,'ccc');
I am trying to get same output, what we get from below UNION query with ANALYTICAL Function.
select * from temp2 where col1 in (1,2,3,4,5)
union
select * from temp2 where col1 in (1,2,5,6)
union
select * from temp2 where col1 in (1,2,7,8);
I am seeking help by this dummy example to understand the concept, how can we use analytical functional over UNION or OUTER JOINS.
In my exact query, I am using same table three times adding UNION clause. here also we scan temp2 three times, so for bulky tables using 'union' would be hampering query's performance
It means i go with three time scans of same table that is not performance oriented. With the help of above required concept, i will try to remove UNIONs from my exact query.
Thanks!!Thanks for your time BluShadow and sorry as i think i couldn't make my query clear.
I try it again. Below there are three queries, you may see all three queries are using same tables. Difference in all three queries are just few conditions, which makes all three queries diff with each other.
I know, u cant run below query in your database, but i think it will convey my doubt to you. I have mentioned no. of rows with each clause and total i am getting 67 rows as my output. (Reason may be first n third query's result set are the subset of Second Query dataset)
So i want to take all common rows as well as additional rows, if present in any of the query. This is getting easliy done with UNION clause but want to have it in other way as here my same is getting scanned again n again.

EVALUATE in OBIEE with Analytic function LAST_VALUE
Hi,
I'm trying to use EVALUATE with analytic function LAST_VALUE but it is giving me error below:
[nQSError: 17001] Oracle Error code: 30483, message: ORA-30483: window functions are not allowed here at OCI call OCIStmtExecute. [nQSError: 17010] SQL statement preparation failed. (HY000)
Thanks
Kumar.Hi Kumar,
The ORA error tells me that this is something conveyed by the oracle database but not the BI Server. In this case, the BI server might have fired the incorrect query onto the DB and you might want to check what's wrong with it too.
The LAST_VALUE is an analytic function which works over a set/partition of records. Request you to refer to the semantics at http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions073.htm and see if it is violating any rules here. You may want to post the physical sql here too to check.
Hope this helps.
Thank you,
Dhar -
Having clause with Analytic function
can you pls let me know if we can use HAVING clause with analytic function
select eid,empno,sum(sal) over(partition by year)
from employee
where dept = 'SALES'
having sum(sal) > 10000I m getting error while using the above,
IS that we can use HAVING clause with partition by
Thanks in advanceYour having clause isn't using an analytical function, is using a regular aggregate function.
You also can't use analytical functions in the where clause or having clause like that as they are windowing functions and belong at the top of the query.
You would have to wrap the query to achieve what you want e.g.
SQL> ed
Wrote file afiedt.buf
1 select deptno, total_sal
2 from (
3 select deptno,sum(sal) over (partition by deptno) as total_sal
4 from emp
5 )
6 group by deptno, total_sal
7* having total_sal > 10000
SQL> /
DEPTNO TOTAL_SAL
20 10875

select (date2-date1)/24 from dual;date2-date1 is amount of days. Divide it by 24 and what? if you multiply it on 24 you will have a chance to know how many hours between these two dates. :-)Don't forget that a DATE type also includes a time component.I suppose it doesn't matter if you did a difference between two dates. The result is always number of days. -
Help needed with analytical function
I want to get the employee details of the highest and 2nd highest salaried employee in a particular department. But also the department should have more than 1 employee.
I tried the query and it gave me proper results. But I'm wondering if there is some other alternative than using the subquery.
Here is the table and the result query :
with t as
select 1 emp_id,3 mgr_id,'Rajesh' emp_name,3999 salary,677 bonus,'HR' dpt_nme from dual union
select 2 ,3 ,'Gangz',4500,800,'Finance' from dual union
select 3 ,4 ,'Sid',8000,12000,'IT' from dual union
select 4 ,null,'Ram',5000,677,'HR' from dual union
select 5 ,4,'Shyam',6000,677,'IT' from dual union
select 6 ,4 ,'Ravi',9000,12000,'IT' from dual
select * from
(select emp_id, mgr_id, emp_name, dpt_nme, salary, row_number() over (partition by dpt_nme order by salary desc) rn from t where dpt_nme in
(select dpt_nme from t group by dpt_nme having count(*) > 1)) where rn < 3Hi,
You need a sub-query, but you don't need more than that.
Here's one way to eliminate the extra sub-query:
WITH got_analytics AS
SELECT emp_id, mgr_id, emp_name, dpt_nme, salary
, ROW_NUMBER () OVER ( PARTITION BY dpt_nme
ORDER BY salary DESC
) AS rn
, COUNT (*) OVER ( PARTITION BY dpt_nme
) AS dpt_cnt
FROM t
SELECT emp_id, mgr_id, emp_name, dpt_nme, salary
, rn
FROM got_analytics
WHERE rn < 3
AND dpt_cnt > 1
;Analytic functions are computed after the WHERE clause is applied. Since we need to use the results of the analytic ROW_NUMBER function in a WHERE clause, that means we'll have to compute ROW_NUMBER in a sub-query, and use the results in the WHERE clause of the main query. We can call the analytic COUNT function in the same sub-query, and use its results in the same WHERE clause of the main query.
What results would you want if there's a tie for the 2nd highest salary in some department? For example, if you add this row to your sample data:
select 7 ,3 ,'Sunil',8000,12000,'IT' from dual union? You may want to use RANK instead of ROW_NUMBER. -

Hi all,
I need some help with ASO mdx function.
Avg({Leaves([Employees].Currentmember)}, [Calculated_Field]). This will give me the average for Calculated_Field for all levels of Employees. But i want to add more dimensions like Region and year.
Please advice how can I achieve this.
Thanks
Andyyou have to use cross join in order to add more dimension members to the formula.This will give you some idea

(select /*+ MATERIALIZE */ branch_code,
row_number() over(partition by branch_code, account order by bkg_date desc ) R,
account,
bkg_date,
lcy_closing_bal
from history t
select REP1.branch_code,
REP1.account,
REP1.bkg_date,
REP1.lcy_closing_bal,
NULL AS second,
REP2.bkg_date bkg_date2,
REP2.lcy_closing_bal lcy_closing_bal2,
NULL AS third,
REP3.bkg_date bkg_date3,
REP3.lcy_closing_bal lcy_closing_bal3
from (SELECT * FROM REP WHERE R=1) REP1, (SELECT * FROM REP WHERE R=2) REP2, (SELECT * FROM REP WHERE R=3) REP3
where
(REP1.BRANCH_CODE = REP2.BRANCH_CODE(+) AND REP1.ACCOUNT = REP2.ACCOUNT(+)) AND
(REP1.BRANCH_CODE = REP3.BRANCH_CODE(+) AND REP1.ACCOUNT = REP3.ACCOUNT(+))The point is I want to restrict (tune) REP before it used ,because , as you can see I need maximum three value from REP (where R=1,R=2,R=3) . Which analytic function and with wich options I have to use to receive only 3 values in each branch_code,account groups at the materializing time ?Radrigez wrote:

The first step is to put your subquery (which doesn't need to be materialized) into an inline view and restrict the result set on r in (1,2,3) as suggested by thtsang - you don't need to query the same result set three times.
Then you're looking at a simple pivot operation (assuming the number of rows you want per branch and account is fixed). If you're on 11g search the manuals for PIVOT, on earlier versions you can do this with a decode() or case() operator.
Step 1 (which could go into another factored subquery) would be something like:
select
branch_code, account,
case r = 1 then bkg_date end bkg_date,
case r = 1 then lcy_closing_bal end lcy_closing_bal,
case r = 2 then bkg_date end bkg_date2,
case r = 2 then lcy_closing_bal end lcy_closing_bal2,
case r = 3 then bkg_date end bkg_date3,
case r = 3 then lcy_closing_bal end lcy_closing_bal3
from
repThis gives you the eight necessary columns, but still (up to) three rows per branch/account.
Then you aggregate this (call it rep1) on branch and account.
select
branch_code, account,
max(bkg_date),
max(lcy_closing_bal),
max(bkg_date2),
max(lcy_closing_bal2),
max(bkg_date3),
max(lcy_closing_bal3)
from
rep1
group by
branch_code, account
order by
branch_code, accountRegards

Help with Sort function in Terminal
Hello all... this is my first post on here as I'm having some trouble with some Termianl commands. I'm trying to learn Terminal at the moment as it is but I would appreciate some help with this one....
I'm trying to sort a rather large txt file into alphabetical order and also delete any duplicates. I've been using the following command in Terminal:
sort -u words.txt > words1.txt
but after a while I get the following error
sort: string comparison failed: Illegal byte sequence
sort: Set LC_ALL='C' to work around the problem.
sort: The strings compared were `ariadnetr\345dens\r' and `ariadnetr\345ds\r'.
What should my initial command be? What is Set LC_ALL='C'?
Hope you guys can help?Various languages distinct sorting - collation - sequences.
The characters can and variously do sort differently, depending on what language is involved.
Languages here can include the written languages of humans, and a few settings associated with programming languages. This is all part of what is known as internationalization and localization, and there are are various documents around on that topic.
The LC_ALL environment variable sets all of the locale-related settings en-mass, including the collation sequence that is established via LC_COLLATE et al, and the sort tool is suggesting selecting the C language collation.
Here, the tool is suggesting the following syntax:
LC_ALL=C sort -u words.txt > words1.txt
This can also be done by exporting the LC_ALL, but it's probably better to just do this locally before invoking the tool.
Also look at the lines of text in question within the files, and confirm the character encoding of the file.
Files can have different character encodings, and there's no reliable means to guess the encoding. For some related information, see the file command:
file words.txt
...and start reading some of the materials on internationalization and localization that are posted around the 'net. Here's Apple's top-level overview.
In this case, it looks like there's an "odd" character and probably an å character on that line and apparently the Svenska ariadnetrådens.
Switching collation can help here, or - if the character is not necessary - removing it via tr or replacing it via sed can be equally effective solutions.
Given it appears to be Svenska, it might work better to switch to Svenska collation thanto the suggested C collation.
I think that's going to be sv_SE, which would make the command:
LC_ALL=sv_SE sort -u words.txt > words1.txt
This is all generic bash shell scripting stuff, and not specific to OS X. If you haven't already seen them, the folks over at tldp have various guides including a bash guide for beginners, and an advanced bash scripting guide - both can be worth skimming. They're not exactly the same as bash on OS X and some specific commands and switches can differ, and as bash versions can differ, but bash is quite similar across all the platforms. -
Help with bash function(set background=dark/light in vimrc)
I couldn't find any gvimrc files so I guess it uses the regular one. And since I work pretty much in X too I thought it would be nice with a function that sets background=light if I'm in X an background=dark if not. Is that possible?
/Richardvimrc configuration is not the same as bash.
You probably want something like this in your ~/.vimrc:
if has('gui_running')
set background=light
else
set background = dark
endif

Audio starts playing about 1/2 a second after set cursor
Sorry if this was answered elsewhere as I wasn't able to find my exact problem after searching. I'm using AA3 and Win7. The issue is this: wherever I place the cursor on the waveform, I'll hit play & the cursor moves, but I won't hear audio until a
