SQL & PL/SQL :: Repeated Volume Value Should Become 0?
Jun 3, 2013
I have a query in oracle report in which i am getting this output.Manager Arnav have 2 employees Inder and kaushal whose salary is 10000 and 20000 respectively,
And another manager is Anjali whose employees are Kavya and inder whose salary is 40000 and 10000 respectively .as Inder is repeated I want the salary become 0 in place of 10000 second time.I am in dilemma,What should i do ,if i want to change 10000 to 0
Manager employee salary
Arnav Tiwari Inder 10000
kaushal 20000
Anjali Kavya 40000
Inder 10000[/b]
What should i do in the formula of salary.according to employee name .means if Name exists already then salary value should be 0 and if it comes for the 1st time then its actual value i.e 10000 should be printed.

I have table with the values as below.
C1C2C3C4
NAMEJOHN10ABC
NAMESMITH30DEF
NAMEROBERT60XYZ
I dont want to print the repeated value(NAME) of C1 multiple times as below.
C1C2C3C4
NAMEJOHN10ABC
SMITH30DEF
ROBERT60XYZ
I could do it using the below query using union with the rownum.
select * from (
select rownum rn, c1,c2,c3,c4 from table_new
) where rn =1
union
select * from (
select rownum rn, decode(c1,null,null),c2,c3,c4 from table_new
) where rn between 2 and 3
Is there any other way of displaying using a single sql query.

I have a query that seems to repeatedly call an index scan on a table for reasons I'm not sure about. Why it would be doing the index scan on totaldwellingarea in the dimensions table (DIMEN_PID_TDWELLAREA) repeatedly? This only seems to happen when I put on the range clause d.totaldwellingarea between scr.lowvalue and scr.highvalue.
I am using Oracle version 9.2.0.3.
select d.propertyid,d.totaldwellingarea, e.size_, scr.size_
from eqid e, dimensions d, brt_eval.size_code_ranges scr
where e.style not in ('1','A','G','L') and e.size_ = '0'
and d.propertyid = e.propertyid and e.style = scr.style and d.totaldwellingarea between scr.lowvalue and scr.highvalue;
CREATE
TABLE "BRT_ADMIN"."EQID"
(
"PROPERTYID" VARCHAR2(20 BYTE) NOT NULL ENABLE,
"EQID" CHAR(10 BYTE),
"ZONE_" CHAR(1 BYTE),
"AREA" CHAR(1 BYTE),

I am in the very early planning stages of a project the goal of which is to identify separate organizations which may in fact be the same organization.
Our first implementation of this task was a process designed to look for a few thousand organizations in a pool of a few hundred thousand organizations. To accomplish this we made heavy use of Oracle's Text index as well as a custom index type we created which utilized n-grams. This approach worked quite well for on-demand editing of the organizations, in which a user might log in and say in addition to what we already know about organization A we also know x, y and z does that change anything and worked acceptably well for the bulk processing we did on our "known" information once a week running for a couple of hours on the weekend.
We have now been tasked with reworking this initial implementation only now we want to look at a set consisting of several million organizations for potential matches which exist within the set. As in our initial implementation we will be breaking what we know about organizations into groupings so we aren't comparing a phone number to an email address and normalizing the data as much as we can so we ignore things like case and punctuation. Even after all this we are still talking about looking for similar values in a group which might be in the tens of millions (some types of data will have more than one value per organization).
My initial thought on the problem is to use n-grams though not in the way we did in the past. The basic idea here is that we break the search values up into all the substrings it is made of and look for other values which have a high number of those substrings in common.
SQL & PL/SQL was the best place for the question, but I could not think of a better one.

I was asked by my systems administrator if I could tell him how much redo log volume, on average, do I figure we generate in a day?
Just wondering how I might calculate this?
We have several production databases. If I wanted to calculate the above for one of them, would it be take all the redo logs for a day and total up the size in bytes? Maybe take a 5 day work week and take the average over the 5 days?

We have Root disk on all the unix servers and is mirrored using SVM using the internal disks. Also VxVM 5.0 MP3 is used as the volume manager to manage the SAN space allocated to the servers. On some instances, SVM is also used for allocating filesystem for application and database
We are required to move all the files from SVM to VxVM.
In the process we are Copying our Oracle binaries from SVM to VXVM.I am planning to use the CPIO command to do the same.Once i move to VXVM (Veritas Volume Manager), i will bring down the SVM.

I am facing a problem with utl_http.write_text in my pl/sql application. My requirement is to write data of size>32k. So I used a clob variable in write_text. But still it is showing numeric or value error when the data size is above 8k.
I have read that chunked transfer encoding will work. But I couldn't find out how this is done.

The prod stats has been implemented in development. The stats has been gathered 2 months back on dev while in production the stats has been gathered 2 weeks back.
My question shouldn't the high volume of data causes changes in plan in both the environment? My thinking is that plan can be different as the high volume of data are changing in prod it may lead to a different plan.
