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 a function that is being called three time using UNION and wanted to know if this can be improved to just one call while incorporating all the table joins.
select field1,fdate,fname,username,stepnum from ( SELECT M.FIELD1, TO_CHAR (M.FIELD_DATE, 'MM/DD/YYYY HH24MISS') AS FDATE, M.FIELDNAME AS FNAME, M.USERNAME,
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 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

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 to write function that receives department name and an aggregation operation (average, maximum, minimum) and apply the operation on the salary of employees working on the given department and return the result.
here is my select statement:

I'm currently doing migration from Oracle 10gR2 RDF to Oracle 11gR2 Semantic Technology.I followed the steps on the documentation and successfully created the network using the following:
----- EXECUTE SEM_APIS.CREATE_SEM_NETWORK('rdf_tblspace'); CREATE TABLE rdf_network_trace (id NUMBER, triple SDO_RDF_TRIPLE_S); --Created SEQUENCE andTRIGGER FOR rdf_network_trace id [code]....
when I looked at my Node Ids, they were like +635762253807433724+, +6118969225776891730+. The problem is, I am not the one who is assigning Node Ids, They were automatically generated when inserting TRIPLE data to the rdf table.
Now, I am trying to come with an alternative. My first thought was to use materialized views with Fast Refresh - refresh only changed rows. This might not even work because there are many contraints when using Fast refresh. I am in the process of learning their data model so I do not know much.
My Oracle DB 10g R2 running on AIX 5.3 OS. When I am shutting down the oracle I see that it is waiting for complete the active calls and I determined that these active calls/processes are from remote machines.
When I try to run this ps -ef as shown below, it shown me number of oracle process with LOCAL=NO
I am working on the quality center oracle database to write a query that fetches all steps of a test case including the ones having calls to tests. Structure of table is explained below. I've made up an example and attached it as an image to this post. This image also has the expected result of the query I want to write.
Table Name: STEPS (This table contains steps belonging to tests. Some steps are simply calls/links to other tests)
Columns: STEP_ID (primary key - integer) STEP_NAME (char) STEP_DESC (char) ORDER (integer) TEST_ID (reference to table TEST.test_id) [code].......
Referring to the example (see attached image), I'm looking to write a query that gives me all steps (including steps from called tests) of the test - "Empty trash from mailbox" in the correct order.
To start with I can write the following query to get steps of the test - "Empty trash from mailbox". SELECT * FROM steps WHERE test_id = (SELECT test_id FROM test WHERE test_name = 'Empty trash from mailbox')
You have a stock_amt value in one table and there is a procedure that updates and substracts from this stock_amt.
lets say in a store a have a stock amount of 50 items and this procedure, for each sale is subtracting from this value and it is not allowed to go below zero. The process, beside the update, on this column (set stock_amt = stock_amt - x) is doing a lot of other updates on other tables and it total it takes like 0.5 seconds. Everything is fine till I want to execute this procedure by 50 users in parallel.
The initial implementation, to avoid some dead locks and we put a lock on that column (stock_amt) but there where to much waits. we cannot hold that lock for 0.5 seconds.
What will be the best approach for this? For this stock amt problem, maybe the solution can be a trade like: do not update that column every time but once in a while, by another process or by a materialize view logic.
but what if my column is a critical value like a Prepay balance or bank balance and it needs to be updated in near real time. What will you do?
As part of an interface I've implemented, I have a 'listener' concurrent request that registers for a dbms_alert and uses wait_one to detect appropriate alerts. When an alert has been detected, a loader concurrent request is kicked-off, before the listener loops back to the wait_one call. I've set a nominal wait_one timeout period of ten minutes. It is not envisaged that many alerts will be raised - maybe several a day at the moment, but I am always reluctant to use polling unless I can avoid it.
Our EBS system has gradually ground to a halt after the release of this program, and the DBAs suspect this as a possible cause. CPU usage was very high overall, with various java-related usage figure also being high.
The overall idea is to have a 'poor-mans' equivalent of OAI, so I'd hope to add more listeners, with each being the equivalent of an OAI adapter.
Surely a big powerful thing like Oracle EBS is not going to keel over just because of a few processes doing little more than waiting for alerts?
I am trying to execute two scripts at the same time (concurrent) in Oracle SQL Developer. I know we can schedule a job using DBMS_job package and define the job. But is there any other way of doing it using Threads ?
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

ADAMS and WARD we're removed from the result, why is it? did it rank it as UNIQUE per sal and ename?
I have a stored procedure that is run from a command within our Clarity application.
The procedure involves some SQL Reads and SQL Inserts.
We have experienced users running the SP at the same time (slim chance to do this) and it creating duplicate entries.
if there is a clever way of preventing the same SP to be run concurrently?
Initially I was thinking of having the first step of the SP to interrogate a flag into a custom table - which the SP then sets to 1 if it is running, and 0 at the end.
Are there better more efficient/effective ways of doing this?
I want to run multiple Reports Concurrently, being called from my Form.
Suppose I have 10 Reports Say Report1, Report2, ....Report10.
I am using "RUN_PRODUCT" to call these Reports from my Form. But it's taking too long time to run all the Reports one after another. Can I run all these Reports Concurrently at the Same time.
I want to add a new validation to restrict concurrent user and/or session from a client. (we have almost 60 client firms using the software to enter daily trasnactions). All users from all clients are connecting to the database using a common functional ID.
What I did was: 1) Add a column 'user_logged_in' in the master table for client and update it as Y when user from that client logged on to the system, 2) Insert the application logon details (we can figure out the client details from this) into a global temp table, 3) Create a logoff trigger to update the 'user_logged_in'flag in client master table by using values from global temp table when session logged off and 4) Restrict the users from same client if the flag is 'Y'
But the problem in this case is logoff trigger will not be executed in case if the session got killed or terminated abnormally.
