I can' use sequence in the group by function and if I get equivalent analytic for above group by even then I can't write row_number as the order by gives detail record
I don't want to wrap this select inside other select
"representant" acct_id per group (about 300 rows total)acct_repres as( select distinct acct_id, origin_id, acct_parm_id from ( select a.* , source_id , dense_rank() over (partition by source_id origin_id order by acct_nbr nulls first, acct_id) as odr from account a join account_parm ap on (a.parm_id = ap.acct_parm_id) ) where odr = 1)select col1 , col2 , ( select accct_id from acct_repres ar where ar.acct_parm_id = t2.acct_parm_id) col3 , ( select count(1) from acct_repres) col4from some_table t1join other_table t2 on (....)
And here it comes.
The "acct_repres" subquery returns more than 300 rows when executed separately. But when used in CTE sometimes (depending on execution plan) it seems to have only one row - the value in the column col4 is "1",while value for col3 is NULL for most of the cases. It looks like the the dense_rank function and the condition "where odr =1" are evaluated at the very end.
When I use MATERIALIZE hint the result was the same. But when I put the result of account_repres into dedicated table and use that table instead of CTE the output is correct.
I have attempted to use the analytic function to keep a running total of the count of active calls based on the connect and disconnect times given for each record row.
I have the following query with analytic function but wrong results on the last column COUNT.
1)I am getting the output order by b.sequence_no column . This is a must. 2)COUNT Column :
I don't want the total count based on thor column hence there is no point in grouping by that column. The actual requirement to achieve COUNT is:
2a -If in the next row, if either the THOR and LOC combination changes to a new value, then COUNT=1 (In other words, if it is different from the following row)
2b-If the values of THOR and LOC repeats in the following row, then the count should be the total of all those same value rows until the rows become different. (In this case 2b-WHERE THE ROWS ARE SAME- also I only want to show these same rows only once. This is shown in the "MY REQUIRED OUTPUT) .
My present query: select r.name REGION , p.name PT, do.name DELOFF, ro.name ROUTE,
[code]...
My incorrect output[PART OF DATA]:Quote: REGIONPT DELOFF ROUTE THOR LOC SEQ COUNT NAASNAAS MAYNOOTHMAYNOOTHR010 DUBLINRD CEL 1 1 NAASNAAS MAYNOOTHMAYNOOTHR010 NEWTOWNRD CEL 2 1

My required output[PART OF DATA]-:Quote: REGIONPT DELOFF ROUTE THOR LOC COUNT NAASNAAS MAYNOOTHMAYNOOTHR010 DUBLINRD CEL 1 NAASNAAS MAYNOOTHMAYNOOTHR010 NEWTOWNRD CEL 1 NAASNAAS MAYNOOTHMAYNOOTHR010 PRIMHILL CEL 1

NOTE :Count as 1 is correctly coming.But where there is same rows and I want to take the total count on them, I am not getting.

I have one form, when i press f7 , it says the "The function has no meaning in this context" , how to make it query enabled block.Actually i am going to that block using when button pressed and execute_query.
I have the below query for which ename column has an index. As of my knowledge below queries 1st and 2st will not use index. Hence i used the 3rd statement and that too its not using the index. Finally i used the 4th query, but even the 4th query is not using the index. Then how do i make this query to use my index??? Do i need to create a function based index for this?
1. select * from emp where ename !='BH' ; 2. select * from emp where ename <> 'BH'; 3. select * from emp where ename not in ('BH'); 4. select * from emp where ename < 'BH' or ename > 'BH';
I have table called Orders with lots of fields from Imports Fields are ConsigneeKey,Shipto,ProductCode. and another table called Product. Main fields are ProductCode,Price,Weight,StdCube. Now I have two list of Consineekey,One which is shipto X area and another is of Y area. I want to make query like separate list of Orders which is shipto X,Y and Common Products in Both X and Y. I will supply list of Consigneekey in where clause.
I have created a custom form. I have field called Order No. When i query on Order no.. i should be able to pick order no as well as other fields related to it. how do i acheive this functionality. I mean the f11 and ctrl f11 querying functionality.
I have one report consist of two user parameters like FROMDATAE and TODATE and two queries in data model..
The 1st query is..
SELECT WONO,MCV_DATE,QTY FROM MCSHOP1 WHERE MCV_DATE BETWEEN :FROMDATE AND :TODATE;
It created two user parameters.ie FROMDATE and TODATE.
And 2nd query like this
SELECT MCVN FROM MCSHOP1 WHERE WONO=:WONO OR WONO LIKE 'RW%'||:WONO;
I dont know how to make 2nd query in data model. becoz the WONO will come from 1st query and LIKE command is there..But I tried in formula Column....but it returns more than one row...
create a procedure so that I could get minus query of 2 table as a result.
I have two table 1- src_table_list ,2- tgt_table_list both tables have 2 columns : serial_no,table_name and 100 records each. and details mentioned in column "table_name" are actually tables name which present in my testing database.
so I need one procedure which will pick one table_name from src_table_list and one table_name from tgt_table_name each time recursively and provide minus query as a result. as below.
select c1,c2,c3,c4 from table1 --(fetched from src_table_list) minus select b1,b2,b3,b4 from table2 --(fetched from tgt_table_list)
create the procedure..as I have to prepare minus query for more than 200 tables and then I need to test them for integration testing..
I have a dynamic query stored in a function that returns a customized SQL statement depending on the environment it is running in. I would like to create a Materialized View that uses this dynamic query.
I'm trying to do a pivot query in oracle to get the years from a column and make a separate column for each. I found an example of the code to use on the internet and i changed it for my own tables but i'm getting errors. Namely a "FROM keyword not where expected" error at the beginning of the 'avg(...' statements.
I have copied the code used in
select stud_id, 2006, 2007, 2008, 2009 from ( select stud_id, avg(case when year=2006 then ((present/poss)*100) else null end) 2006, avg(case when year=2007 then ((present/poss)*100) else null end) 2007, avg(case when year=2008 then ((present/poss)*100) else null end) 2008, avg(case when year=2009 then ((present/poss)*100) else null end) 2009 from attendance.vw_all_attendance_perc group by stud_id );
SQL> ed Wrote file afiedt.buf 1 select * 2 from (select deptno, ename, sal 3 ,dense_rank() over (partition by deptno order by sal desc) rank 4 from emp)

why is that i just added ename on the ORDER BY part of the DENSE_RANK and then SQL> ed Wrote file afiedt.buf 1 select * 2 from (select deptno, ename, sal 3 ,dense_rank() over (partition by deptno order by sal desc, ename) ran
[code]...
ADAMS and WARD we're removed from the result, why is it? did it rank it as UNIQUE per sal and ename?
How can I rewrite this without the analytic functions?
SELECT employee_ID, first_name, salary, RANK() OVER(ORDER BY salary desc) toprank_desc, RANK() OVER(ORDER BY salary ASC) toprank_asc FROM employees ORDER BY first_name
I have a table (events) with this structure: customer_id, event_id, ... For each customer_id there can be several rows in the table. I need to run a query of the format: select customer_id, expensive_function(customer_id),... from events.
The expensive_function to be applied to customer_id in the query is really expensive (a Java class calculating a check sum) and the events table has billions of rows.
Rows in events table have same customer_id for a few rows, then continue with a different customer_id ang again coming back to the first, etc.
I was thinking that it should be a way to trigger calculation of expensive_function only when customer_id changes, in order to reduce the number of calls. Only my knowledge about SQL is not going that far and I cannot use PL/SQL or any other procedural language, need to stick to standard SQL (or Oracle version of it).
I am building a reporting table using the count analytic function in order to count up several different attributes in one statement.What I find is that this method quickly eats up my TEMP space. This is 10gR2. I have attempted to use MANUAL workarea policy with as large ofsort_area_size as possible (2G) but that does not seem to have any effect on performance or TEMP usage. The RAW table is about 12G with 75 million rows. I am not that concerned about execution time, but rather TEMP usage.
--INSERT into <object>... select distinct file_sid,filename,control_numb,processing_date,file_class, vendor_id,vendor_desc, c_status_id,c_status_desc,
[code]...
I am not seeing any increase in onepass or multipass executions on the PGA during execution of this statement using...
SELECT CASE WHEN low_optimal_size < 1024*1024 THEN to_char(low_optimal_size/1024,'999999') || 'kb <= PGA < ' || (high_optimal_size+1)/1024|| 'kb' ELSE to_char(low_optimal_size/1024/1024,'999999') ||
[code]...
I'd like to get a better explaination of how analytics use the instance resources and TEMP space. For example if I add a count with a different window (such as the last two columns commented in the above query) I blow out my temp space (70G). Is the critcal factor the use of distinct? or multiple windows? or something else?
I need to return an ordered list of documents. The documents may belong to a set id (optional) and if so, are either a "master" or a "duplicate" type. For each set there can be only one master but many duplicates. My goal is to group all the sets together such that each master is proceeded by its duplicates.
There's also a documents table containing the documentid and among other things a page_count. In the following example I want to sort the documents first by page count but preserving the master/dupe grouping. Any documents which don't belong to a set or are just a duplicate without a master i want at the end of my set but also ordered by page count.
Here's an example set that I would want to order by:
As you can see I have a little bit of everything here. Docs 2001 and 2002 are the typical set of 1 master and its duplicate. Docs 2010, 2011, and 2012 is the same just a set of 3. Doc 2004 is a master but without any duplicates. Docs 2003 and 2014 are duplicates without a master (these docs have a master in the table but that doc isn't in the set i need to order by). Docs 2008 and 2009 do not belong to a set and as such do not have a master/dupe type.
The result i'm looking to achieve will be ordered as follows:
As I said above I first want to get the groupings of master/dupes and order ascending on the masters page count. For each duplicate of a master I then want to order the duplicates by page count. After I finished ordering all the master/dupe groups I then want to move on to the rest of the documents which will contain documents that don't belong to a set along with documents which are duplicates but have no master in my set. However, documents which are masters but without duplicates should have been ordered along with the other master/dupes groupings.
With this all in mind I have just been completely overwhelmed as to where to even start. Am I using analytic functions? Hierarchical stuff?
I have a question regarding analytic functions. I've been working with some functions, but I can't achieve the one which gives me the pretend result. I know to resolve this without using a function, with a internal select, but I think the analytical function is faster and proper.
desc tbl_female Name Null Type ------------------- ---------- ----------------- ANI NOT NULL VARCHAR2(12) CHAT_ID VARCHAR2(25) AGE VARCHAR2(5) RECORD_FILE VARCHAR2(25) SUB_DATE_TIME DATE STATUS VARCHAR2(15) LOGIN_STATUS VARCHAR2(15) CIRCLE_NAME VARCHAR2(10) INTEREST VARCHAR2(10) HOBBIES VARCHAR2(10) OLD_ID VARCHAR2(25) SORTED NUMBER FAIL NUMBER TIME NUMBER FLAG NUMBER POINT NUMBER SF NUMBER ACTIVE NUMBER
and Query depending on this table sometimes provide a row or sometimes not. Query is as follows which we are using
SELECT ANI INTO SUBANI FROM (SELECT ANI FROM TBL_FEMALE WHERE point=(select max(point) from tbl_female where circle_name in('pb','hr','hp','jk','pb','bir','dl','mp','mum','mh','gj') and sf=0 and login_status='LOGIN' and status in ('A','B') ) and circle_name in('pb','hr','hp','jk','pb','bir','dl','mum','mh') and sf=0 and login_status='LOGIN' and status in ('A','B') ORDER BY RANDOM.RAND_MAX(20)) WHERE ROWNUM = 1;
can I rewrite the following query without using the 'ROW_NUMBER() OVER ' part.The query is supposed to pull out the records whose CODE is not NULL and has most recent date for UPDATE_DATE . The reason I wanted to do this is, When I embed this query in between many other queries along with JOINs, My oracle server is unable to execute. So, I thought its better to supplant 'ROW_NUMBER() OVER ' logic with something else and try it. .
CURRENT QUERY: SELECT a.* FROM (SELECT b.*, ROW_NUMBER() OVER (PARTITION BY b.PIDM ORDER BY b.UPDATE_DATE DESC) AS Rno FROM ( SELECT * FROM SHYNCRO WHERE CODE IS NOT NULL )b )a WHERE a.Rno = 1
A B ---------------------- 2*3 2*4*5 4*5 column B contain no data.
I want to create a function which can be used in a select query,and the output should come like that :-
A B ---------------------- 2*3 6 2*4*5 40 4*5 20
Means column B contains the resultant value of column A.And the above output should come through a select statement.You can use any function inside the select statement.
